Twenty-five patients (16 with malignant soft-tissue tumors and 9 with suspected recurrence), previously studied with conventional radiography and Computed Tomography (CT), were examined with Magnetic Resonance (MR) imaging. MR findings were surgically and anatomo-histopathologically confirmed. Six more patients with benign lesions were examined for differential diagnosis. MR capabilities are here evaluated to detect and eventually characterize the lesion, and to assess its exact location. No false positives were found, and there was only one false negative, in a case of recurrent Malignant Fibrous Histiocytoma (MFH). In another case of MFH the infiltration of the adjacent vessels and nerves was not imaged. After a careful review of all the examinations, MR imaging appears to be able to provide much information for surgical planning about tumor extent and margins, thanks to its contrast resolution between tumor and surrounding anatomical structures. Therefore, MR imaging can be reasonably employed as the examination of choice when a soft-tissue tumor is clinically suspected, because of the multi-planar images it provides with and of its differential imaging parameters.
25例患者（16例患有恶性软组织肿瘤，9例疑似复发），此前已接受传统X线摄影和计算机断层扫描（CT）检查，随后接受了磁共振（MR）成像检查。MR检查结果经手术及解剖组织病理学证实。另外6例患有良性病变的患者接受了检查以进行鉴别诊断。在此评估了MR检测病变并最终对其进行特征描述以及评估其确切位置的能力。未发现假阳性结果，仅在1例复发性恶性纤维组织细胞瘤（MFH）病例中出现1例假阴性结果。在另一例MFH病例中，未显示出相邻血管和神经的浸润情况。在对所有检查进行仔细回顾后，由于MR在肿瘤与周围解剖结构之间具有对比分辨率，因此它似乎能够为手术规划提供有关肿瘤范围和边界的大量信息。因此，当临床怀疑存在软组织肿瘤时，由于MR能提供多平面图像及其鉴别成像参数，故可合理地将其用作首选检查方法。
