【摘要】 目的比较Carebolus与testbolus两种测试方法在CEMRA中的有效性。方法搜集行CE-MRA的病例64例,其中头颈部26例,胸腹部18例,四肢20例。均在行CE-MRA前先进行Carebolus(51例)或testbolus(13例)测试。结果用Carebolus测试的有5例显示不满意;用testbolus测试的有1例不满意。其余CE-MRA效果均满意。结论Carebolus与testbolus两种测试方法各有优缺点,临床上应根据不同的成像血管和不同的血流动力学特点进行选择。更多还原

【Abstract】 Objective To evaluate the effectiveness of carebolus and testbolus in contrast-enhanced magnetic resonance angiography (CE-MRA). Methods CE-MRA were performed in sixty-four patients, including 26 CE-MRA of head-neck, 18 CE-MRA of thorax-abdomen and 20 CE-MRA of limbs. Either t carebolus or testbolus was performed before contrast-enhancement magnetic resonance angiography. Results High quality images were displayed except five cases with carebolus test and one case with testbolus test. Conclusion Optimal imaging protocol of test method in contrast-enhanced magnetic resonance angiography should be selected according to the target vessels and its characteristics.更多还原
