[摘要] 目的 探討后循環缺血性眩暈采用CT、MRI和磁共振動脈成像診斷價值。方法 方便選取后循環性眩暈患者60例,均為該院神經內科或耳鼻咽喉科2015年4月—2016年4月收治,行CT、MRI和磁共振動脈成像檢查。采用CT對腦梗死進行檢查時結果呈陽性,不存在腦梗死病變的則呈陰性。而采用MRI對腦實質病變檢查時結果呈陰性,不存在腦實質病變的才呈陽性。 結果 該次選取的60例患者,采用CT檢查,陽性16例,占26.7%;陰性44例,占73.3%。MRI檢查,陽性46例,占76.7%,陰性14例,占23.3%,故差異有統計學意義(P<0.05)。基底動脈A型42條,B型、C型分別4條,無異常2條,A型合并B型改變2條。結論 后循環缺血性眩暈采用磁共振檢查,可為確診提供有力的參考依據,值得在臨床廣泛應用。

[Abstract] Objective To investigate the value of CT, MRI and magnetic resonance imaging in the diagnosis of Posterior Circulation Ischemia Vertigo. Methods Convenient selection 60 cases of posterior circulation vertigo were selected, all of which were admitted to our hospital from April 2016 to April 2015. The patients were treated with CT, MRI and magnetic resonance imaging. CT was positive in the examination of cerebral infarction, and there was no negative cerebral infarction. And the results were negative when MRI was used for the examination of brain parenchymal lesions, and there was no brain parenchymal lesions. Results The selected 60 patients, using CT examination, 16 cases were positive, accounting for 26.7%; negative in 44 cases, accounting for 73.3%. MRI examination, 46 cases were positive, accounting for 76.7%, negative in 14 cases, accounting for 23.3%, so with statistical difference(P<0.05). Basilar artery type A 42, type B, type C were 4, no abnormal 2, A type combined with type B change 2. Conclusion Posterior Circulation Ischemia Vertigo using magnetic resonance examination, can provide a powerful reference for diagnosis, it is worth in clinical widely used.

后循環也稱椎基底動脈系統,由大腦后動脈、椎動脈、基底動脈構成,主要負責對腦組織供血[1]。在臨床腦血管缺血性疾病領域,后循環缺血(PCI)較為常見,其以中老年人為好發群體,主要表現為行走不穩、頭痛、意識消失、眩暈等,對患者生存質量和身心健康均造成了嚴重威脅[2]。現階段,臨床缺乏對后循環缺血性眩暈與其他疾病引發頭暈的有效辨別,使治療受到不利影響,隨著影像學技術在近年取得的巨大發展成就,明顯提高了后循環缺血性眩暈的檢出率[3]。該次研究在2015年4月—2016年4月方便選取60例后循環性眩暈患者,就CT、MRI、磁共振動脈成像診斷情況展開探討,現報道如下。
