多序列MRI在急性期脑出血中的临床应用价值分析

Clinical Application Value of Multisequence MRI in Acute Cerebral Hemorrhage

目的旨在分析多序列MRI在急性期脑出血中的临床应用价值。方法选取我院2016年1月-2017年7月收治的急性期脑出血患者共49例,患者均进行了多序列MRI检查,收集患者临床资料、影像学资料,分析多序列MRI扫描在检查急性脑出血中的价值。结果共31例(42.85%)患者出血灶T1WI中呈现为等信号,边界不清,呈现略低信号者9例(18.36%),环状低信号者9例(18.36%)。T2WI序列中,多数患者图像表现为血肿区域高信号,其中存在混杂信号,26例(53.06%)患者可见周边高信号水肿带,相对较窄,1例(2.04%)患者灶周水肿带呈明显高信号,伴中线移位。T2FLAIR为极低或低信号,3例(6.12%)患者T2FLAIR呈现外高内低信号;DWI序列中血肿中央为极低信号,周围存在中度水肿呈现明亮高信号,边界欠清,13例(26.53%)患者可见小片状稍长T2信号。12例(24.48%)患者血肿区中央出现极低信号,周边局部高信号区范围增宽,合并存在局部低信号区。结论多序列MRI检查可有效显示急性期脑出血的出血部位及信号特征,成像质量高,可为临床治疗提高有效影像学依据。

Objective To investigate the clinical value of multi-sequence magnetic resonance imaging(MRI) in acute cerebral hemorrhage. Methods A total of 49 cases of the acute phase of cerebral hemorrhage patients from our hospital from January 2016 to July 2016 were selected. All patients have performed multi-sequence MRI examination,and the patients’ clinical data, imaging data were collected. Two associated chief physicians analyzed the characteristics according to the result of the MRI scan in the acute phase of cerebral hemorrhage. Results The hemorrhage demanstrated equal signal on T1 WI in 31 patients(42.85%), with unclear boundary, slightly lower signal in 9 cases(18.36%), and circular low signal in 9 cases(18.36%). In T2 WI sequences, most patients with high signal images showing in the hematoma region, there were also mixed signals. And the peripheral high-signal edema zone was seen in 26 cases(53.06%), which was relatively narrow. In one case(2.04%), the peripheral edema zone was significantly high, with the midline displacement. T2 FLAIR signal of the lesion was extremely low or showed low signal,while in 3 cases(6.12%), the signal on T2 FLAIR was high, medium and low signal. In the DWI sequence, the center of hematoma was extremely and showed low signal, and the surrounding moderate edema presented bright and high signal, with unclear boundary. In12 cases(24.48%), the area of hematoma showed extremely low signal, and the peripheral areas that gave high signal were widened, and the area of local low signal area was implied.Conclusion Multi-sequence MRI examination can effectively display the location and image features of acute cerebral hemorrhage, with high imaging quality, and can improve the effective imaging data for clinical treatment.
