摘要
目的:探讨CDFI和MRA对颈动脉粥样硬化狭窄的诊断价值。材料与方法:用CDFI、MRA两种方法检查42例缺血性脑梗塞患者和40例对照组的颈动脉。结果:CDFI检查显示缺血性脑梗塞患者颈动脉病变发生率明显高于对照组(P<0.01)。本组病例轻度、重度狭窄的MRA与CDFI诊断完全符合,MRA和CDFI结果具有极好的一致性。结论:CDFI与MRA在诊断颈动脉狭窄中具有互补作用,两者结合使用能提高评估狭窄程度的准确性。
Purpose： To explore the value of CDFI and MRA for the diagnosis of the carotid stenosis. Materials and Methods. Comparative study on CDFI and MRA for 42 in- patients with ischemic cerebral infarction and the control group consisted of 40 in- patients without cerebmvascular disease. Results： The ultrasound examination showed that the occurrence rate of the lesion of the carotid arteries in patients with ischemic cerebral infarction was significantly higher than that of control group （P 〈 0.01）. THe diagnosis of the mild and severe carotid stenosis with MRA were in accord with CDFI. MRA and CDFI were in accord with each other. Condusion： CDFI an MRA are mutually complementary in diagnosing the carotid stenosis. Combined use of CDFI and MRA can increase the accuracy of the evaluation of the level of the stenosis.
