摘要
分析了2000例低磁场 MRI 的临床应用。检查部位以头颅、脊柱(含脊髓)、腹部居多,阳性率为77.8%。MRI 对腔隙性梗塞、中线及后颅窝肿瘤、椎管肿瘤、脊髓损伤等疾病的诊断优于 CT;在肝癌与肝血管瘤的诊断及鉴别诊断方面也优于 CT。而脑外伤、脑出血等仍应以 CT 为首选的检查方法。
To evaluate the usefulness of low Powered magnetic field of MRI 0.15-T, we retrospectively studied the MR imagings of 2,000 consecutive cases in brain,spine, abdomen,and thorax.The total positive rate is 77.8%.It was found that MRI is better than CT in demonstrating the cerebral lacunar infarction,tumors in medbrain,posterior cranial fossa and spinal canal,and also for the trauma in spinal cord.MRI is superior to CT in dioagnsing and differentiating tumors and hemangioma of liver.However,we still recommend that CT should be the first choice for trauma and hemorrhage of brain.
