增强磁共振血流成像对颅内血管性和占位性病变的诊断

目的：探讨Gd-DTPA增强MRA对颅内血管性和占位性病变的诊断价值。方法：经手术和/或病理及临床观察证实的63例占位性和历管性病变做增强MRA 3D-TOF法扫描，并与非增强扫描对照。结果：增强MRA能显示非增强MRA不能显示的动脉瘤和AVM、板障血管瘤的供血动脉、引流静脉及占位性病变的供血动脉。在显示海绵状血管瘤方面两者无明显差别。结论：Gd-DTPA增强MRA 3D-TOF法对颅内血管性和占位性病变的诊断有更大的应用价值。

Gd-DTPA Enhancement MR Angiography of Intracranial Occuping and Vascular Diseases

Purpose To investigate the diagnostic valuation of Gd DTPA enhancement MRA in intracranial occuping and vescular diseases. Methods Gd DTPA MRA(63 cases), MRA without Gd DTPA(16 cases)as a control group was performed with Elscint Prestige 2.0T MR,MRA. 56 cases were proved by operation or pathology, 7 cases were proved by clinical observation. Results The shape of aneurysms, the feeding arteries, the draining veins of AVM and diploe angioma, the feeding arteries of occuping were clearly showed by Gd DTPA enhancement MRA and were not showed by MRA without Gd DTPA.There wasn't much difference between cavernous angioma with Gd DTPA enhancement MRA and MRA without Gd DTPA in the shape and blood supply of cavernous angioma. Conclusion Gd DTPA enhancement MRA is useful and worthy for showing blood circulation of intracranial occuping and vascular diseases.
