Magnetic resonance (MR) and CT of 50 musculoskeletal neoplasms were compared to investigate the relative values of these modalities in the assessment and staging of musculoskeletal neoplasms and to determine how often they are complementary and when they are redundant. The material included 25 benign and 25 malignant neoplasms, of which 33 were skeletal and 17 were of soft tissue origin. Magnetic resonance was superior to CT with respect to all morphologic criteria except for cortical bone destruction, calcification, ossification, and the assessment of lytic and sclerotic changes in flat bones. Magnetic resonance was found to be complementary to CT in 48% of the cases (30% malignant, 18% benign). Use of both MR and CT was considered redundant in 52% of the cases (20% malignant, 32% benign). Magnetic resonance was found to be the modality of choice for all benign and malignant soft-tissue neoplasms. Both modalities are complementary and necessary for complete evaluation of malignant skeletal tumors. Benign skeletal tumors should be considered for evaluation by CT, MR, or both on an individual case basis.
对50例肌肉骨骼肿瘤患者进行磁共振成像（MR）和计算机断层扫描（CT）检查，并比较两者在肌肉骨骼肿瘤评估和分期中的相对价值，以确定它们互补和冗余的频率。研究材料包括25例良性肿瘤和25例恶性肿瘤，其中33例起源于骨骼，17例起源于软组织。除皮质骨破坏、钙化、骨化以及扁平骨溶骨性和硬化性改变的评估外，磁共振成像在所有形态学标准方面均优于计算机断层扫描。在48%的病例中（30%为恶性，18%为良性），磁共振成像与计算机断层扫描具有互补性。在52%的病例中（20%为恶性，32%为良性），同时使用磁共振成像和计算机断层扫描被认为是多余的。对于所有良性和恶性软组织肿瘤，磁共振成像被认为是首选的检查方式。对于恶性骨肿瘤的完整评估，两种检查方式都是互补且必要的。对于良性骨肿瘤，应根据具体病例考虑采用计算机断层扫描、磁共振成像或两者结合进行评估。
