This study was undertaken to investigate the relative merits of magnetic resonance (MR) imaging and computed tomography (CT) in the evaluation of primary lesions of the cerebral ventricles. Since 1982, 14 patients, 7 males and 7 females, aged 8 to 68 years were diagnosed as harboring ventricular mass lesions. Eight masses were located in the lateral, 5 in the third, and one in the fourth ventricle. The diagnostic contribution and relative merits of two imaging modalities were compared in each case. In 57 per cent of cases the CT scan was of superior diagnostic value, and in 21 per cent of the patients MR imaging proved to be either more sensitive or specific than CT scanning. The availability of intravenous contrast agents for CT and not MR, as well as the capability of CT to definitely identify lesion calcification, accounted for the better performance of CT scanning in this series of patients.
本研究旨在探讨磁共振（MR）成像和计算机断层扫描（CT）在评估脑室原发性病变中的相对优势。自1982年以来，14例患者（7例男性，7例女性，年龄8至68岁）被诊断为患有脑室肿块病变。8个肿块位于侧脑室，5个位于第三脑室，1个位于第四脑室。对每种情况下两种成像方式的诊断贡献和相对优势进行了比较。在57%的病例中，CT扫描具有更高的诊断价值，在21%的患者中，MR成像被证明比CT扫描更敏感或更具特异性。CT有静脉造影剂而MR没有，以及CT能够明确识别病变钙化，这解释了在这组患者中CT扫描表现更好的原因。
