【摘要】：目的探討腦灰質(zhì)異位的MRI平掃及增強(qiáng)掃描特征及價(jià)值,提高對(duì)腦灰質(zhì)異常的表現(xiàn)及臨床特征的認(rèn)識(shí)。方法回顧分析2009年9月至2012年9月經(jīng)手術(shù)病理證實(shí)的10例腦灰質(zhì)異位患者,所有患者均進(jìn)行MRI平掃和增強(qiáng)掃描,分析其臨床及影像學(xué)表現(xiàn)。結(jié)果腦灰質(zhì)異位患者的MRI平掃表現(xiàn)如下,MRI平掃T1、T2、FLAIR軸位可見(jiàn)四疊體池偏左側(cè)枕葉區(qū)域團(tuán)片狀混雜信號(hào)影,病灶邊界欠清楚,信號(hào)不均勻;MRI平掃IR T1序列可見(jiàn)四疊體池偏左側(cè)枕葉區(qū)域病灶顯示更明顯;MRI平掃e DWI序列呈等信號(hào),未見(jiàn)擴(kuò)散受限。MRI平掃診斷的確診率達(dá)90%。MRI增強(qiáng)掃描軸位、冠狀位、矢狀位,可見(jiàn)四疊體池偏左側(cè)枕葉區(qū)域病灶無(wú)明顯強(qiáng)化。MRI增強(qiáng)掃描的確診率達(dá)100%。MRI增強(qiáng)掃描的確診率高于MRI平掃,診斷結(jié)果與臨床病理診斷結(jié)果相比,差異無(wú)統(tǒng)計(jì)學(xué)意義。結(jié)論腦灰質(zhì)異位的MRI表現(xiàn)具有特征性,MRI在腦灰質(zhì)異位的診斷中具有非常高的應(yīng)用價(jià)值,可以作為腦灰質(zhì)異位的重要檢查方法。
[Abstract]:Objective to explore the characteristics and value of MRI scan and enhanced scan of the heterotopic gray matter, and to improve the understanding of the abnormal performance and clinical characteristics of the brain gray matter. Methods from September 2009 to 2012, 10 patients with ectopic gray matter confirmed by operation and pathology in 9 menstrual period were retrospectively analyzed. All patients underwent MRI plain scan and enhanced scan, and their clinical and imaging findings were analyzed. Results the MRI of patients with cerebral heterotopia scan as follows, MRI scan, T1 T2, FLAIR axial visible quadrigeminal left occipital lobe patchy areas of partial mixed signal and the lesion boundary less clear, the signal is not uniform; MRI scan IR T1 sequence showed partial left occipital lobe region quadrigeminal lesions showed more obvious e DWI; MRI scan sequence was equal signal, no diffusion limited. The diagnosis rate of MRI scan was 90%. MRI scan axial, coronal, sagittal, visible partial quadrigeminal cistern left occipital lobe lesion showed no enhancement. The diagnostic rate of MRI enhanced scan was 100%. The diagnostic rate of MRI enhanced scan was higher than that of MRI, and there was no significant difference between the diagnosis and the clinicopathological diagnosis. Conclusion the MRI findings of gray matter heterotopic is characteristic. MRI has very high application value in the diagnosis of ectopic gray matter. It can be used as an important examination method for heterotopic gray matter.
