摘 要：
INTRODUCTION: In our institutional experience, determination of the alpha (alpha) angle at MR arthrography as an indicator of the likelihood of cam-type femoroacetabular impingement (FAI) is fraught with inconsistency. The aims of this study were to quantify the degree of variability in and calculate the diagnostic accuracy of the alpha angle in suggesting a diagnosis of cam impingement, to determine the accuracy of a positive clinical impingement test, and to suggest alternative MR arthrographic measures of femoral head-neck overgrowth and determine their diagnostic utilities. MATERIALS AND METHODS: We carried out a retrospective analysis of MR arthrographic studies performed during a 4-year period, combined with chart analysis, which allowed identification of 78 patients in whom surgical correlation was also available. The status of a preoperative clinical impingement test was also noted. Patients were designated as having cam-type FAI (Group A, n = 39) if intra-operative femoral head-neck junction bony osteochondroplasty/arthoscopic femoral debridement was performed. Group B (n = 39) acted as controls. Three radiologists independently and blindly performed a series of measurements (alpha angle and two newly proposed measurements) in each patient on two separate occasions. An alpha angle of greater than 55 degrees was considered indicative of the presence of cam-type FAI. RESULTS: Performance values for alpha angle measurement were poor for each observer. There was considerable (up to 30% of the mean value) intra-observer variability between the first and second alpha angle measurements for each subject. Binary logistic regression analysis confirmed that the alpha angle is of no value in predicting the presence or absence of cam-FAI. A statistically significant difference existed between Groups A and B with regard to the newly proposed anterior femoral distance (AFD; p = 0.004). Using an AFD value of 3.60 mm or greater as being indicative of the presence of cam-FAI yields a 0.67 performance measure (95% confidence interval 0.55-0.79). The second proposed parameter (femoral neck ratio) was of no value in suggesting the presence or absence of this condition. The sensitivity, specificity, and positive and negative predictive values of the clinical impingement test were 76.9%, 87.2%, 85.7% and 79.1% respectively. CONCLUSIONS: Femoral alpha angle measurement is associated with considerable variability. This index performed poorly in our patient population and was statistically of no value in suggesting the presence or absence of cam-FAI. One of our proposed measures, the AFD, outperformed the alpha angle, though to an insufficient degree to suggest its routine incorporation into clinical practice. Our experience suggests that the clinical impingement test remains the most reliable predictor of the presence of this condition.

摘 要：
OBJECTIVES: To evaluate the short-term, mid-term and long-term follow-up of 285 patients who had undergone percutaneous vertebroplasty (PVP) for osteoporotic vertebral compression fracture (VCF) in our department from 2003 to 2006, and, particularly, to analyse our data on the safety and the usefulness of PVP for durable pain reduction, mobility improvement and the need for analgesic drugs. MATERIALS AND METHODS: Follow-up analysis was made through a questionnaire completed by the patients before and after PVP (1 week, 1 year and 3 years). The results are reported by subdivision of patients into groups (by gender, age and number of treated vertebrae), with special reference to pain management, drug administration and quality of life. RESULTS: All patients (285) were followed up for 1 week, 186 for 12 months, and 68 patients were followed up for 3 years. One week after PVP all patients reported normal ambulation (with or without pain), and more than 95% were able to perform activities of daily living (ADL) either without pain or with mild pain. There was no difference in pain relief between the genders after 1 week's follow up, but after 3 years better analgesia results were observed in women. There was no statistically significant difference in the visual analogue scale (VAS) values before PVP between age groups (P = 0.7) and gender (P = 0.4); Patients younger than 75 years had better outcomes than did older ones (>75 years) at 1 week and 1 year follow up. Patients also reported significant reduction in drug therapy for pain. CONCLUSIONS: PVP is a safe and useful procedure for the treatment of vertebral osteoporotic fractures. It produces enduring pain reduction, improves patients' mobility and decreases the need for analgesic drugs.

摘 要：
BACKGROUND: The purpose of this retrospective study was to assess the frequency of magnetic resonance imaging (MRI) signs of iliotibial band friction (ITBF) in patients with advanced medial compartment knee osteoarthritis. MATERIAL AND METHODS: Proton density-weighted (PDw) fat-saturated (fatsat) MR images (1.5 T, slice thickness (SL) 2.5-3 mm, eight-channel phased array coil) of 128 patients with isolated advanced osteoarthritis of the medial knee compartment and complete or subtotal (>80%) loss of cartilage were evaluated. There were 41 men and 87 women. Mean age was 63 years, range 34-89 years. The control group consisted of 94 patients with medial meniscus degeneration without cartilage loss (56 men and 38 women, mean age 50 years, range 16-89 years). MRI signs of ITBF were evaluated in both groups [poorly defined abnormalities of signal intensity and localized fluid collection lateral, distal or proximal to the lateral epicondyle; signal intensity abnormalities superficial to or deep by the iliotibial band (ITB)]. Transverse images were evaluated separately. Consensus evaluation using all imaging planes was performed. RESULTS: Of 128 patients with osteoarthritis, 95 had moderate or advanced MRI signs of ITBF (74.2%). Eighty-nine patients (69.5%) had advanced degeneration of the meniscus. In the control group, 26 of 94 patients had only moderate MRI signs of ITBF. There was a statistically significant difference between both groups for the presence of MR signs of ITBF (P <or= 0.01). CONCLUSION: MRI signs of ITBF were frequently present in patients with severe medial compartment osteoarthritis of the knee. Joint space narrowing with varus knee deformity may be a cause of ITBF.

摘 要：
OBJECTIVE: To correlate magnetic resonance (MR) image findings with pain response by provocation discography in patients with discogenic low back pain, with an emphasis on the combination analysis of a high intensity zone (HIZ) and disc contour abnormalities. MATERIALS AND METHODS: Sixty-two patients (aged 17-68 years) with axial low back pain that was likely to be disc related underwent lumbar discography (178 discs tested). The MR images were evaluated for disc degeneration, disc contour abnormalities, HIZ, and endplate abnormalities. Based on the combination of an HIZ and disc contour abnormalities, four classes were determined: (1) normal or bulging disc without HIZ; (2) normal or bulging disc with HIZ; (3) disc protrusion without HIZ; (4) disc protrusion with HIZ. These MR image findings and a new combined MR classification were analyzed in the base of concordant pain determined by discography. RESULTS: Disc protrusion with HIZ [sensitivity 45.5%; specificity 97.8%; positive predictive value (PPV), 87.0%] correlated significantly with concordant pain provocation (P < 0.01). A normal or bulging disc with HIZ was not associated with reproduction of pain. Disc degeneration (sensitivity 95.4%; specificity 38.8%; PPV 33.9%), disc protrusion (sensitivity 68.2%; specificity 80.6%; PPV 53.6%), and HIZ (sensitivity 56.8%; specificity 83.6%; PPV 53.2%) were not helpful in the identification of a disc with concordant pain. CONCLUSION: The proposed MR classification is useful to predict a disc with concordant pain. Disc protrusion with HIZ on MR imaging predicted positive discography in patients with discogenic low back pain.

摘 要：
OBJECTIVE: To assess the reliability of measurements of spinal canal narrowing, vertebral body compression, and interpedicular widening in burst fractures in radiography compared with multidetector computed tomography (MDCT). MATERIALS AND METHODS: Patients who had confirmed acute vertebral burst fractures over an interval of 34 months underwent both MDCT and radiography. Measurements of spinal canal narrowing, vertebral body compression, and interpedicular widening from MDCT and radiography were compared. RESULTS: The 108 patients (30 female, 78 male, aged 16-79 years, mean 39 years) had 121 burst fractures. Eleven patients had multiple fractures, of which seven were not contiguous. Measurements showed a strong positive correlation between radiography and MDCT (Spearman's rank sum test: spinal canal narrowing k = 0.50-0.82, vertebral compression k = 0.55-0.72, and interpedicular widening k = 0.81-0.91, all P < 0.05), except for the cervical spine (k = -0.50 to 0.61, with all P > 0.25) and for interpedicular widening in the thoracic spine (k = 0.35, P = 0.115). The average difference in measurements between the modalities was 3 mm or fewer. CONCLUSION: Radiography demonstrates interpedicular widening, spinal canal narrowing and vertebral compression with acceptable precision, with the exception of those of the cervical spine.

摘 要：
OBJECTIVE: Tibial tubercle lateral deviation and patellofemoral chondromalacia are associated with anterior knee pain (AKP). We hypothesized that increased tibial tubercle lateral deviation and patellofemoral chondromalacia on magnetic resonance imaging correlates with the presence of AKP and with failure of nonoperative management. MATERIALS AND METHODS: In this retrospective comparative study, a blinded musculoskeletal radiologist measured tibial tubercle lateral deviation relative to the trochlear groove in 15 controls, 15 physical therapy responders with AKP, and 15 physical therapy nonresponders with AKP. Patellar and trochlear cartilage was assessed for signal abnormality, irregularity, and defects. RESULTS: The mean tibial tubercle lateral deviation in controls, physical therapy responders, and physical therapy nonresponders were 9.32 +/- 0.68, 13.01 +/- 0.82, and 16.07 +/- 1.16 mm, respectively (data are mean +/- standard deviation). The correlation coefficients for tubercle deviation, chondromalacia patellae, and trochlear chondromalacia were 0.51 (P < 0.01), 0.44 (P < 0.01), and 0.28 (P < 0.05), respectively. On analysis of variance, tubercle deviation and chondromalacia patellae contributed significantly to prediction of AKP and response to physical therapy. The presence of chondromalacia patellae and a tubercle deviation greater than 14.6 mm is 100% specific and 67% sensitive with a positive predictive value of 100% and negative predictive value of 75% for failure of nonoperative management. CONCLUSION: Subjects with AKP have more laterally positioned tibial tubercles and are more likely to have patellar chondromalacia. Patients with AKP, chondromalacia patellae, and a tubercle deviation greater than 14.6 mm are unlikely to respond to nonoperative treatment. Knowledge of tibial tubercle lateralization and presence of chondromalacia patellae may assist clinicians in determining patient prognosis and selecting treatment options.

摘 要：
OBJECTIVE: The objective was to investigate the clinical and radiological characteristics of central giant cell granulomas (CGCGs) of the jaws. METHODS: A retrospective analysis of a 20-year database was performed regarding both clinical and radiological features of 22 patients affected with CGCGs of the jaws. RESULTS: Fourteen women and 8 men were included with the age range of 7-81 years (mean 31.7 years). Among the 22 lesions, 16 were located in the mandible and 6 in the maxilla. Painless swelling was the most common clinical feature in 18 of all cases. Limited mouth opening was noted in 2 patients where the lesions involved the condyle. Radiographically, 13 lesions were homogeneously osteolytic and 9 lesions were trabeculated. Fifteen lesions were unilocular and 14 lesions presented with well-defined but not sclerotic margins. CT images in 5 patients clearly showed the trabeculation within the lesions. The follow-up ranged from 1.5 to 11 years with a mean period of 5 years. Three out of 9 aggressive and 1 out of 13 nonaggressive lesions developed recurrence. CONCLUSIONS: Diagnosis of CGCGs of the jaws depends on both correct interpretation of clinical, radiographic and pathological data. Differentiation between aggressive and nonaggressive CGCGs should be considered to improve individual treatment planning.

摘 要：
OBJECTIVE: The purpose of this study was to evaluate the feasibility, quality, and possible future implications of magnetic resonance imaging (MRI) of the human hand and wrist at 7 T. MATERIALS AND METHODS: Images of the left hand of a healthy volunteer were acquired with a 7- and a 1.5-T whole body system and comparatively analyzed. Axial and coronal two-dimensional gradient echo (GRE) images with inflow saturation, coronal 3D GRE images, and time-of-flight angiographies were obtained without averaging. Image details were related to the complex hand anatomy. RESULTS: With the 7-T protocols established in this study, high-quality and high-resolution images of the hand and wrist were obtained. In the 2D GRE images at 7 T, small anatomical structures of the hand were depicted in vivo with superior detail and resolution, compared to 1.5 T and published studies at lower field strength. Signal-to-noise ratios (SNRs) were approximately five times higher at 7 T compared to 1.5 T. Additionally, thin 3D GRE images with good quality of the whole hand were obtained in a short acquisition time. Moreover, time-of-flight angiographies of the small hand arteries have been acquired without the application of contrast agents. CONCLUSION: Seven-tesla imaging of the hand can be used in vivo with ultra-high resolution and sufficient SNR.

摘 要：
The ischiorectal fossa may give rise to a wide variety of pathological entities, although it is composed of relatively few structures. Developmental cysts are included among the list. Large epidermoid cysts in the ischiorectal fossa have been previously described (Fujimoto et al., Clin Imaging 17:146-148, 1993; Ng et al., Can J Surg 49:435-436, 2006). However, to the best of our knowledge, there is no published case in the English literature of a dermoid cyst within the ischiorectal fossa. Using magnetic resonance (MR) imaging and a subsequent ultrasound-guided biopsy, we were able to offer a focused differential that included a dermoid cyst within the ischiorectal fossa in a 55-year-old man presenting with a painful mass on the buttocks. Hair and fatty components were obtained by targeted ultrasound-guided biopsy. On MR imaging, the mass was seen to be well circumscribed and registered a heterogeneous T1-weighted signal that corresponded to layers of fat and debris on short-tau inversion recovery (STIR) imaging. A well-defined ball of fat was noted centrally within the lesion, with a speckled low T1 and low T2 signal within it. Hair admixed with fat was obtained from it by targeted ultrasound-guided biopsy. There was no enhancement of the lesion after administration of gadolinium. On ultrasound, the lesion was well circumscribed and heterogeneous; the echogenic area corresponded to the fat signal seen on magnetic resonance imaging (MRI). The lower level echoes within the lesion corresponded to the debris seen on MRI. The central rounded area of speckling, registering fine posterior shadowing corresponded to the hairy contents obtained by the targeted ultrasound-guided biopsy. A differential diagnosis of all lipomatous lesions was included in the pre-biopsy report: fat necrosis within a lipoma; well-differentiated liposarcoma; myxoid liposarcoma and dermoid cyst. Histopathological diagnosis following complete surgical resection was that of a dermoid cyst.

摘 要：
A 53-year-old woman developed a subchondral insufficiency fracture of the right femoral head after undergoing a liver transplantation. Radiographs obtained at her first visit demonstrated a slight subchondral collapse in the superolateral portion of the femoral head. Magnetic resonance imaging (MRI) disclosed an irregular, discontinuous, low-intensity band on the T1-weighted image. After 7 months of conservative treatment, the hip pain and the radiograph abnormalities had both disappeared. On the follow-up T1-weighted MR image obtained 17 months after the onset, the band of low signal intensity was not obvious. A subchondral insufficiency fracture is one of the diagnoses to be considered in patients presenting with hip pain after a liver transplantation.

摘 要：
Ulnar artery pseudoaneurysms are very uncommon. The least common etiological mechanism is a single direct trauma. It is important to identify these lesions, which may have important clinical complications such as distal thrombosis with digital ischemia or gangrene. This report describes the features of sonography and magnetic resonance angiography of a histologically confirmed ulnar artery pseudoaneurysm.
