| 摘 要： | 目的 探讨多层螺旋CT动态扫描肝灌注异常的CT表现、原因和临床意义.方法 符合一过性肝实质强化(THPE)患者48例,对各种类型的肝灌注异常现象的CT表现、病因和发生机制进行分析.结果 48例共72处THPE,其中,与肿瘤相关34例,非肿瘤者14例,32(44.4%)处表现平直边界扇形或楔形,20(27.7%)处不规则斑片状,15(20.8%)处结节状,5(6.9%)处呈网格状.结论 各种原因导致肝动脉血流重新分配和肝动脉门静脉异常交通,是产生肝灌注异常的主要机制.

| Abstract: | Objective To discuss CT findings,etiology and its clinical significance of hepatic perfusion disorders. Methods 48 patients with transient hepatic parenchymal enhancement (THPE) were chosen for this study. The etiologies,CT findings and mechanisms of different patterns of THPE were analysed. Results There were 72 THPE lesions in the 48 patients. Of 48 cases,34 cases were hepatic tumors and 14 cases were non-tumors. The lesions appeared as fan-shape or wedge-shape in 32(44. 4%), irregular patchs in 20(27. 7% ),nodular in 15 (20. 8%) and grid-form in 5 (6. 9 %). Conclusion Redistributing hepatic arterial flow and ar-terioportal shunt( APS) caused by various conditions are mainly the mechanism resulting in THPE. |
