Magnetic resonance (MR) images of 13 intracranial mass lesions taken with the intravenous administration of gadolinium-DTPA were evaluated in comparison with precontrast computed tomography (CT), postcontrast CT, and precontrast MR. In the MR images taken with Gd-DTPA, tumor delineation improved in eight of 13 cases (62%) in comparison with precontrast MR images, and in seven of 13 cases (54%) in comparison with the overall evaluation of precontrast CT, postcontrast CT, and precontrast MR images. Tumor demarcation was unchanged in the remaining cases; no deterioration was observed with Gd-DTPA administration. MR imaging with Gd-DTPA should be performed to better evaluate the extent of intracranial mass lesions and to provide additional information.
对13例颅内肿块病变在静脉注射钆喷酸葡胺(Gd-DTPA)后所做的磁共振(MR)图像进行了评估,并与注射造影剂前的计算机断层扫描(CT)、注射造影剂后的CT以及注射造影剂前的MR图像进行比较。在注射Gd-DTPA后所做的MR图像中,与注射造影剂前的MR图像相比,13例中有8例(62%)肿瘤轮廓清晰度提高;与注射造影剂前的CT、注射造影剂后的CT以及注射造影剂前的MR图像的整体评估相比,13例中有7例(54%)肿瘤轮廓清晰度提高。其余病例中肿瘤边界无变化;注射Gd-DTPA后未观察到恶化情况。应进行注射Gd-DTPA的MR成像,以更好地评估颅内肿块病变的范围并提供更多信息。
