多层螺旋CT与钆贝葡胺增强MRI对肝癌诊断价值比较

目的 比较多层螺旋CT与钆贝葡胺（Gd-BOPTA）增强MRI对肝癌的诊断价值。资料与方法 对19例同组患者依次行多层螺旋CT双期增强扫描、MR平扫及Gd-BOPTA动态、延迟扫描。比较多层螺旋CT动态增强扫描、MR平扫＋Gd-BOPTA动态扫描及联合MRI3种方法病灶检出的敏感性及对肝癌病灶定性诊断的敏感性、特异性和准确性。结果 3组病灶检出的敏感性及对肝癌病灶诊断的准确性以联合MRI组较高，差异有统计学意义。结论 Gd-BOPTA增强MRI对病灶检出的敏感性及肝癌病灶诊断的准确性优于多层螺旋CT。

Comparative Study of the Diagnostic Value of Gd-BOPTA Enhanced MR Imaging and MSCT in Hepatic Carcinoma

Objective To compare the diagnostic value of Gd BOPTA enhanced MR imaging with multi slice helical CT(MSCT) in hepatic carcinoma.Materials and Methods 19 patients with hepatic lesions were underwent with both dual phase enhanced MSCT scanning, MR plain scanning, Gd BOPTA enhanced MR imaging and delay MR scanning. The potential of lesion detection and sensitivity, specificity and accuracy of qualitative diagnosis with dual phase enhanced MSCT scanning, MR plain scanning, Gd BOPTA dynamic enhanced MR and combined MRI were analyzed.Results The combined MRI was superior to the others in lesion detection and accuracy of diagnosis which had statistical difference.Conclusion The potential of lesion detection and characterization of hepatic lesions are improved by Gd BOPTA enhanced MRI compared with that by MSCT.
