Seventy-four patients referred for computed tomography (CT) and ultrasound examination with a presumptive diagnosis of pancreatic disease have been studied using a low-field (0.08 T) magnetic resonance (MR) imaging instrument. A further 50 patients being examined for non-pancreatic disease were also examined to assess the appearances of the normal pancreas. All the MR examinations were performed using an interleaved saturation-recovery/short inversion time (TI) inversion-recovery sequence. Part or all of the pancreas was seen in 96% of normal cases. In inflammatory disease, MR was more accurate than either CT or ultrasound for diagnosis, whilst for the demonstration of pancreatic tumours, MR was found to be no better or worse than either CT or ultrasound. The use of specific T1 measurement for soft-tissue characterization was not useful because of the large overlap in values between normal, inflamed and malignant pancreatic tissue. T1 measurement was found to be useful in differentiating different pathological fluids.
对74例因疑似胰腺疾病而转诊接受计算机断层扫描（CT）和超声检查的患者，使用低场（0.08T）磁共振（MR）成像仪进行了研究。另外对50例因非胰腺疾病接受检查的患者也进行了检查，以评估正常胰腺的表现。所有MR检查均采用交错饱和恢复/短反转时间（TI）反转恢复序列进行。在96%的正常病例中可看到部分或全部胰腺。在炎症性疾病中，MR在诊断方面比CT或超声更准确，而在显示胰腺肿瘤方面，MR与CT或超声相比并无优劣之分。由于正常、发炎和恶性胰腺组织之间的值有很大重叠，使用特定的T1测量进行软组织特征分析并无用处。发现T1测量在区分不同病理液体方面有用。
