The usefulness of dynamic MR and fat suppression imaging was investigated in 19 patients with pancreatic duct cell carcinoma. In addition to conventional spin echo imaging, dynamic MR and fat suppression imaging were performed. These images were evaluated for the detectability of lesions. The detectability of lesions was classified as good, fair or poor. On T1 weighted images, 26% of cases were evaluated as "good" and 32% as "fair". On dynamic MRI, 69% of cases were evaluated as "good" and 26% of cases as "fair". On pre- and postcontrast fat suppression images, 32% and 28%, respectively, were evaluated as "good", and 47% and 39% as "fair". Neither T2 weighted images nor enhanced T1 weighted images were useful. Direct comparison between dynamic MR and fat suppression images was also done. In 42% of cases, dynamic MR was superior to fat suppression images and in 42%, dynamic MRI was equal to fat suppression. In 16% of cases, fat suppression was superior to dynamic MRI. It was concluded that dynamic MR and fat suppression imaging were more useful than conventional spin echo imaging for the detection of pancreatic carcinoma.
对19例胰腺导管细胞癌患者进行了动态磁共振成像（MR）和脂肪抑制成像的有效性研究。除了传统的自旋回波成像外，还进行了动态MR和脂肪抑制成像。对这些图像进行病变可检测性评估。病变的可检测性分为良好、尚可或较差。在T1加权图像上，26%的病例评估为“良好”，32%为“尚可”。在动态MRI上，69%的病例评估为“良好”，26%为“尚可”。在对比剂注射前后的脂肪抑制图像上，分别有32%和28%评估为“良好”，47%和39%为“尚可”。T2加权图像和增强T1加权图像均无帮助。还对动态MR和脂肪抑制图像进行了直接比较。在42%的病例中，动态MR优于脂肪抑制图像，42%的病例中，动态MRI与脂肪抑制图像相当。在16%的病例中，脂肪抑制优于动态MRI。得出的结论是，动态MR和脂肪抑制成像在检测胰腺癌方面比传统自旋回波成像更有用。
