[摘要] 目的 探討出血性腦梗死應(yīng)用核磁共振成像的診斷意義。 方法 選擇2015年6月21日~2017年5月19日我院70例出血性腦梗死患者為研究對象,根據(jù)診斷方式的不同均分為兩組。對照組采取CT檢查,觀察組予以核磁共振成像。觀察診斷準(zhǔn)確性及診斷特征。 結(jié)果 觀察組診斷準(zhǔn)確概率(94.29%)顯然高于對照組(P<0.05)。在圖像表現(xiàn)方面,可見斑片狀或者大片狀信號(hào)(長T1長T2),T1WI序列斑點(diǎn)狀、類圓形等低信號(hào)區(qū),高信號(hào)區(qū)表云霧狀,邊界清晰;T2WI序列可見內(nèi)信號(hào)不均勻(大片狀高信號(hào)區(qū));增強(qiáng)掃描表現(xiàn)為地圖樣、花邊狀強(qiáng)化(11.43%),腦回樣強(qiáng)化(2.86%);出血信號(hào)以低信號(hào)或等信號(hào)為主;額葉、顳葉、頂葉、顳及頂葉、小腦半球和顳、枕及頂葉概率分別為28.57%、14.29%、20.00%、11.43%、8.57%、17.14%;在梗死類型方面,腦深部血腫)、不規(guī)則出血、梗死區(qū)外周出血、混合型分別為11.43%、57.14%、20.00%、11.43%。 結(jié)論 針對出血性腦梗死患者,采取核磁共振成像技術(shù)臨床價(jià)值較高。

[Abstract] Objective To investigate the diagnostic significance of applying magnetic resonance imaging in hemorrhagic cerebral infarction. Methods A total of 70 patients with hemorrhagic cerebral infarction in our hospital from June 21, 2015 to May 19, 2017 were studied. They were divided into two groups according to different diagnostic methods. The control group took CT examination, the observation group took magnetic resonance imaging. Observed the diagnostic accuracy and diagnostic features. Results The diagnostic accuracy of the observation group(94.29%) was obviously higher than that of the control group(P<0.05). In terms of image features, patchy or large patchy signals(long T1, long T2), T1WI sequential spotted, quasi-circular low signal areas, and cloud-like high signal areas with clear boundaries; visible signals in T2WI sequence were non-uniform(Large patchy high signal area); enhanced scan showed map-like, lace-like enhancement(11.43%), gyrus-like enhancement(2.86%); low signal or equal signal took up most of the bleeding signals; frontal lobe, temporal lobe, parietal lobe, temporal and parietal lobe, cerebellar hemispheres and temporal, occipital and parietal lobes were 28.57%, 14.29%, 20.00%, 11.43%, 8.57% and 17.14% respectively; In terms of infarction type, hematoma of deep brain, irregular hemorrhage, peripheral bleeding in infarction area, mixed type were 11.43%, 57.14%, 20.00%, 11.43% respectively. Conclusion For patients with hemorrhagic cerebral infarction, the clinical value of using magnetic resonance imaging is significant.

出血性腦梗死即為腦梗死患者發(fā)病后,出現(xiàn)缺血區(qū)再灌注現(xiàn)象,引發(fā)繼發(fā)性出血,影像學(xué)檢查可見高密度造影(局限性或大面積繼發(fā)性出血),也被稱之為梗死后腦出血。近幾年來[1],此疾病發(fā)病概率逐漸增高,嚴(yán)重威脅患者身體健康及生命安全。出血性腦梗死與動(dòng)脈粥樣硬化、高血壓、糖尿病以及高血脂等因素有直接相關(guān)性,主要誘因?yàn)樾脑葱阅X栓塞,相比原發(fā)性腦出血,疾病早期并無特異性表現(xiàn),需通過CT等檢查明確疾病,預(yù)后較差,極易導(dǎo)致死亡,故尋找可靠的診斷方法意義重大,可有效控制病情發(fā)展、降低死亡率。本文旨在探討核磁共振成像應(yīng)用于出血性腦梗死中的臨床價(jià)值。
1 資料與方法
1.1 一般資料
選取2015年6月21日~2017年5月19日出血性腦梗死患者(70例),按照診斷方式的差異,均分為兩組。對照組:平均年齡(54.18±3.27)歲,最大65歲,最小47歲,男女比21:14(共35例),平均發(fā)病時(shí)間(8.04±1.16)d。觀察組:平均年齡(54.18±3.27)歲,最大67歲,最小45歲,男女比19:16(共35例),平均發(fā)病時(shí)間(8.20±1.32)d。兩組上述資料比較差異無統(tǒng)計(jì)學(xué)意義(P>0.05),具有可比性。……
