摘 要：
OBJECTIVE: With digital radiography development, information technology (IT) companies have developed specific software for templating procedures, requiring individual magnification assessments for each patient. The aim of this study was to determine the mean magnification factor of digital radiographs and to evaluate the possibility of using the mean magnification factor or clinical information in templating. MATERIALS AND METHODS: We retrospectively evaluated 100 primary total hip arthroplasty digital radiographs using the femoral head prosthesis as a calliper to determinate the mean magnification factor. Working on the assumption that altitude of the hip during radiograph is decisive in modification of magnification factors, we also looked for a correlation between weight, body mass index (BMI), altitude and magnification factor. RESULTS: The magnification factor was 126% (121-130%). A relationship was found between magnification factor (Mf) and weight (Mf = 7.10(-4)x weight (kg) + 1.21), but not BMI. In 98% of cases, if the weight-correlated formula is used, the sizing is correct or the error is +/- 1 mm. With the mean method the sizing is correct or within 1 mm in only 78.2% of cases. CONCLUSION: Levels of accuracy for the mean magnification factor and the weight-correlated formula are not as high as individual assessments using a calliper; however, they could be used in everyday practice where individual magnification factors have not been calculated.

摘 要：
OBJECTIVE: The objective was to demonstrate the feasibility of MRI/CT fusion in demonstrating lumbar nerve root compromise. MATERIALS AND METHODS: We combined 3-dimensional (3-D) computed tomography (CT) imaging of bone with 3-D magnetic resonance imaging (MRI) of neural architecture (cauda equina and nerve roots) for two patients using VirtualPlace software. RESULTS: Although the pathological condition of nerve roots could not be assessed using MRI, myelography or CT myelography, 3-D MRI/CT fusion imaging enabled unambiguous, 3-D confirmation of the pathological state and courses of nerve roots, both inside and outside the foraminal arch, as well as thickening of the ligamentum flavum and the locations, forms and numbers of dorsal root ganglia. Positional relationships between intervertebral discs or bony spurs and nerve roots could also be depicted. CONCLUSION: Use of 3-D MRI/CT fusion imaging for the lumbar vertebral region successfully revealed the relationship between bone construction (bones, intervertebral joints, and intervertebral disks) and neural architecture (cauda equina and nerve roots) on a single film, three-dimensionally and in color. Such images may be useful in elucidating complex neurological conditions such as degenerative lumbar scoliosis(DLS), as well as in diagnosis and the planning of minimally invasive surgery.

目的：目的是证明在证明腰神经根损害的MRI可行性/ CT融合。材料与方法：我们结合三维与3（3 - D型）计算机断层扫描（CT）的骨显像三维磁共振成像（MRI）神经架构（马尾神经根和两个软件的使用VirtualPlace患者）。结果：虽然神经根病变的条件无法评估使用核磁共振，脊髓造影或CT造影，三维成像/ CT融合成像功能明确的，三维的病理状态和神经根的课程，内外确认在椎间孔拱，以及增厚的黄韧带和地点，形式和背根神经节数。椎间盘之间的位置关系，或骨神经根骨刺，还可以描述。结论：使用三维成像/ CT检查为腰椎地区融合成像成功揭示了骨头建设的关系（骨，椎间关节，椎间盘）和神经结构（马尾和神经根在一个电影，3）二维和彩色。此类图片可能是有用的阐明，如退行性（DLS）公司腰椎侧弯复杂的神经系统疾病，以及在诊断和微创手术的规划。
