摘 要：
Magnetic resonance imaging plays an integral role in the detection and characterization of marrow lesions, planning for biopsy or surgery, and post-treatment follow-up. To evaluate findings in bone marrow on MR imaging, it is essential to understand the normal composition and distribution of bone marrow and the changes in marrow that occur with age, as well as the basis for the MR signals from marrow and the factors that affect those signals. The normal distribution of red and yellow marrow in the skeleton changes with age in a predictable sequence. Important factors that affect MR signals and allow detection of marrow lesions include alterations in fat-water distribution, destruction of bony trabeculae, and contrast enhancement. This two-part article reviews and illustrates these issues, with an emphasis on the practical application of MR imaging to facilitate differentiation of normal marrow, tumor, and treatment-related marrow changes in oncology patients.

摘 要：
OBJECTIVE: The objective was to describe the imaging findings following acute injury to the calf musculature. DESIGN AND PATIENTS: We retrospectively reviewed 59 MR examinations in patients who sustained injuries to the calf muscle from April 2001 to September 2004 (48 men, 11 women), with an average age of 31 and 47 years respectively (range in men 20-53; range in women 33-63). Attention was directed to the frequency of muscle involvement, the location of the injury within the musculotendinous unit and the extent of the injury. RESULTS AND CONCLUSIONS: A total of 79 separate sites of strain injury were identified (39 solitary, 20 dual). Of the 39 isolated strains, injury to the gastrocnemius was most common (19 out of 39; 48.7%), preferentially involving the medial head in 18 cases and the lateral head in 1 case. The soleus was also commonly involved (18 out of 39; 46.2%), with 2 cases (5.1%) of distal avulsions of the plantaris. Of the 20 dual injuries, a combination of gastrocnemius injury with soleus injury was the most frequent finding (12 out of 20; 60%). Dual injuries of both heads of the gastrocnemius muscles were demonstrated in 4 cases (20%), with the soleus and tibialis posterior injured in 3 cases (15%). A combination of soleus and flexor hallucis longus injury was seen in 1 case (5%). CONCLUSION: This retrospective study utilizing MRI demonstrates that the medial head of the gastrocnemius is the most commonly injured muscle of the calf, closely followed by the soleus, the latter finding rarely reported in the sonographic literature. Dual injuries of the calf muscle complex occur much more commonly than previously reported and may be of prognostic significance.

摘 要：
OBJECTIVE: The objective was to evaluate the magnetic resonance (MR) appearance of patellar osteochondritis dissecans (OCD). MATERIALS AND METHODS: We retrospectively analyzed MR images of 16 patients (18 cases, mean age 20 years) using OCD of the patella. In 5 cases surgery was carried out, and we compared the surgical findings with the MR imaging findings in these cases. RESULTS: In all 18 cases, OCD was located central-inferiorly on the patella, and the average size was 11 x 11 x 7 mm. Subchondral deformities were present in 16 out of 18 cases (88.9%), subchondral cyst formation in 4 cases (22.2%), reactive bone marrow signal in 8 cases (44.4%), overlying patellar cartilage abnormality in 14 cases (77.8%), loose body in 2 cases (11.1%), patella alta in 8 cases (44.4%), hypoplastic sulcus in 7 cases (38.9%), and synovitis in 4 cases (22.2%). In all 5 cases in which surgery was carried out, the cartilage abnormality classified on the MR images was confirmed, and a loose body was removed at arthroscopy in 2 of the 5 cases. CONCLUSION: Magnetic resonance imaging of patellar OCD typically shows subchondral deformity and variable abnormalities of the overlying patellar cartilage located central-inferiorly on the patella.

摘 要：
PURPOSE: To assess the heterogeneity of magnetic resonance (MR) imaging characteristics in primary lymphoma of bone (PLB), in particular the non-aggressive appearance. SUBJECTS AND METHODS: In a retrospective study, MR imaging features were analyzed in 29 patients with histologically proven PLB. The following parameters were evaluated: tumor size, bone marrow and extension into soft tissues, signal characteristics of bone marrow and soft-tissue components, including enhancement, and involvement of cortical bone (complete disruption, focal destruction, permeative destruction and cortical thickening). RESULTS: PLB presented with extension into the soft tissue in 22 (76%) of 29 patients, was only subtle in three of these 22 patients, and was absent in seven patients. Signal intensity (SI) of the soft-tissue part was most frequently homogeneously isointense with muscle on T1-weighted images (90%) and high on T2-weighted images (91%). Enhancement was predominantly homogeneous and diffuse (82%). In 93% of patients cortical bone appeared abnormal: among those patients complete cortical disruption was seen in 28%, with extension into soft tissues in all but one patient; a permeative pattern of destruction was present in 52% of patients, 66% of these had an associated soft-tissue mass. Two patients with normal-appearing cortical bone had no extension into soft tissues. In two patients focal cortical destruction was noticed; in one patient cortical bone was homogeneously thickened, and in one patient PLB was selectively localized within the cortical bone. SI of the bone marrow tumor component was more frequently heterogeneous (in 54%), compared with the soft-tissue component, being high on T2-weighted images in 89%, intermediate in 7% and low in 4%. Similarly, enhancement was heterogeneous in 59%. CONCLUSION: The MR imaging appearance of PLB is variable. In 31% of PLB patients, the tumor was intra-osseous, with linear cortical signal abnormalities or even normal-appearing or thickened cortical bone without soft-tissue mass, and, as such, PLB may not infrequently look non-aggressive on MR imaging.

摘 要：
INTRODUCTION: Radiological scoring systems used in experimental osteomyelitis combine several factors into a single score. Because response of bone tissue to infection is a dynamic process, such systems have limited ability to differentiate between treatment groups. The analyzing of radiological criteria separately at different stages of the disease may be superior to a general score. METHODS AND METHODS: Osteomyelitis was induced with Staphylococcus aureus in the left tibiae of 72 adult Wistar albino rats. The rats were assigned to one of six different treatment groups. Their radiographs were graded (1) by the use of previously published general scoring systems and (2) by the evaluation of periosteal reaction, bone deformation, diaphyseal widening, osteolysis, soft tissue swelling, bone mineral content (BMC) and bone mineral density (BMD), separately. The assessments were performed 3 weeks after induction as well as 3 weeks and 6 weeks after treatment. RESULTS: Periosteal reaction and diaphyseal widening demonstrated significant differences within 3 weeks of treatment, contrary to the general scores. After 6 weeks of treatment, individual criteria, including diaphyseal widening, osteolysis and BMC but only one of the general grading scores, were able to differentiate between treatment groups. CONCLUSIONS: For differentiation of treatments in experimental osteomyelitis individual assessment of radiological criteria is superior to previously published general scoring systems.

摘 要：
OBJECTIVE: The objective was to report the clinical and imaging patterns of nine cases of stress fractures of the rib diagnosed in Italian Olympic rowers. PATIENTS AND METHODS: Nine patients with stress fractures of the rib detected from 103 (8.7%) Italian team rowers competing between May 2000 and May 2006 were identified based on the database of a sports medicine institute. All athletes were male. They were aged between 17 and 31 years (mean: 24.4). Patient weight, fracture location, rowing side and imaging methods employed were noted. RESULTS: The diagnosis was made based on history, clinical examination and Tc-99m MDP bone scintigraphy. Eight of the 9 fractures were located anterolaterally between the fourth and ninth rib. In 1 of the 5 athletes with standard radiographs, a fracture line was visible and in 4 there was callus formation. In 2 athletes sonography was performed, which detected discontinuity of the rib surface and callus formation (1 case each). CONCLUSION: Stress fractures of the ribs are relatively common in competitive rowers. They are characterized by increasing lateral chest pain and typical scintigraphic, radiographic and sonographic findings.

摘 要：
OBJECTIVE: To evaluate MRI as a problem-solving tool for patients with an unexplained failed total hip replacement following conventional radiological assessment. METHODS AND MATERIALS: Patients' informed consent was obtained in all cases. Institutional review board approval was obtained. Twenty-eight patients with unexplained failed total hip replacements following conventional radiological assessment underwent additional MR imaging with an optimised turbo-spin echo sequence. Images were reviewed by two musculoskeletal radiologists by consensus and compared with findings at surgery, or following response to image-guided intervention or clinical follow-up. RESULTS: Of the 28 patients, MRI revealed an unsuspected diagnosis explaining the cause of prosthesis failure in 15 patients. In eight of 15 patients in this group, subsequent minimally invasive image-guided intervention obviated the need for revision total hip replacement. No cause for prosthesis failure was identified in 13 patients. DISCUSSION: MRI may be successfully undertaken in patients following total hip replacement, and, when performed, it frequently leads to an unsuspected diagnosis, allowing informed patient treatment. In this study it allowed the identification of an unsuspected diagnosis in over 50% of cases.

摘 要：
OBJECTIVE: To assess the specificity and sensitivity of MR arthrography of the hip in comparison with arthroscopy for the evaluation of intra-articular loose bodies. DESIGN: Over a 3-year period, 81 consecutive patients underwent a total of 82 hip arthroscopies by a single orthopedic surgeon for intractable hip pain. Of the 82 arthroscopies, 70 had pre-operative MR arthrograms. Of these, 57 were available for retrospective review, after which they were compared with the operative notes of the subsequent arthroscopies. RESULTS: Of 82 arthroscopies 16 (20%) demonstrated intra-articular loose bodies, while, in the study group, nine of 57 had loose bodies (16%). There was a total of seven discordant cases (five false negatives and two false positives). The sensitivity of MR arthrography for detection of intra-articular loose bodies was 44%, while the specificity was 96%. CONCLUSION: While the specificity of MR arthrography for the detection of intra-articular loose bodies was high (96%), the sensitivity was not nearly as good (44%).

摘 要：
Giant cell tumor (GCT) is a rare complication of Paget disease of bone. It usually occurs in the skull or pelvic bones of patients with long-standing polyostotic disease. This report describes a 62-year-old patient who presented with monostotic Paget disease of the distal femur complicated by GCT. He had a 2-year history of discomfort and pain in his left knee. Conventional plain films and MRI demonstrated the characteristic bone changes of Paget disease and an associated lytic lesion involving the epiphyseal and metaphyseal regions of the distal femur. A diagnostic curettage showed the characteristic histopathologic features of Paget disease and GCT. There was no evidence of malignancy. The clinicopathologic features of this rare lesion are described and correlated with a review of the literature.

摘 要：
The injection of polymethylmethacrylate (PMMA) is a minimally invasive image-guided procedure that is typically used to treat vertebral body fractures due to osteoporosis or neoplastic involvement. The injection of PMMA into various other locations including the sacrum, acetabulum, pedicles, femur and tibia has been reported previously, and these procedures have, overall, been highly effective at alleviating pain and discomfort. Although the injection of PMMA into the vertebral body is a very common procedure that has been performed for over 2 decades for the percutaneous treatment of vertebral body fractures, the percutaneous injection of PMMA has not been reported in the English literature as treatment for superior pubic ramus fractures. We report the percutaneous treatment of an acute superior pubic ramus fracture and of a chronic insufficiency fracture of the superior pubic ramus using a parasymphyseal approach to access the region of injury.

摘 要：
We report a case of granulocytic sarcoma exclusively manifesting as diffuse intramuscular infiltration of the proximal upper and lower limb girdle and the torso muscles in a patient with previous history of acute myelogenous leukemia 5a. Whole-body CT showed widespread distribution of ill-defined intramuscular, homogeneously enhancing lesions. On whole-body MRI, lesions were homogeneously hyperintense on fat saturated T2-weighted images, isointense on T1-weighted images and strongly enhancing after intravenous gadolinium contrast administration. Histopathology revealed muscular infiltration of blast cells with identical immunochemistry to the initial manifestation of leukemia, diagnostic for an extramedullary relapse manifesting as granulocytic sarcoma. CT and MRI characteristics of this previously undocumented manifestation of granulocytic sarcoma should assist in the identification of such cases.

摘 要：
We report a case of cystic teratoma of the diaphragm that was considered to be a soft tissue lipoma by the preoperative examination. A magnetic resonance imaging revealed an 8 x 8 cm well-demarcated, homogeneous mass. On T1- and T2-weighted imaging, the mass was isointense to fat. On the fat-suppressed imaging, the signal from the mass was reduced to the same degree as subcutaneous fat. We performed marginal excision. The tumor contained a large number of hairs and oily liquid; and it was connected to the diaphragm.

摘 要：
Sarcoidosis is a noncaseating granulomatous disease that involves multiple organs, most commonly the lungs, lymph nodes, skin, and eyes, but may be clinically evident in any organ system. Symptomatic muscular sarcoidosis is very rare and has been reported in only 1.4% of known sarcoidosis cases, while skeletal involvement has been reported in 1-13%. Different types of muscular and osseous sarcoidosis have been described in the literature. We present a case of muscular sarcoidosis, which is unique in its clinical presentation and imaging findings. The presence of the marked periosteal reaction, which has never been described with muscular sarcoidosis, also makes this case unique.

摘 要：
Berardinelli-Seip lipodystrophy (BSCL) is a rare, but widely distributed, congenital disorder of metabolism. It is characterized by insulin-resistant diabetes mellitus and marked deficiency of adipose tissue. The clinical and imaging features of the syndrome are mostly due to fat deficiency, diabetes, or to manifestations of secondary hyperinsulinemia, which results from the failure of the tissues to respond to insulin. Absence of fat may be generalized, or depending upon the subtype of the disease, may not affect areas where fat plays a mechanical function, such as the palms and soles. Muscles appear hypertrophic. In addition, characteristic, but idiopathic, peri-articular lytic lesions may be seen in some individuals. The combination of imaging, clinical, and laboratory findings is characteristic and readily recognized once the components of the syndrome are known.
