【摘要】：目的:探討3.0T磁共振斷層血管成像(MRTA)各種掃描方法在腦神經(jīng)血管壓迫綜合征中的應(yīng)用,并分析各種方法的優(yōu)缺點(diǎn)。方法:對(duì)50例臨床診斷為面肌痙攣的患者,進(jìn)行t1-vibe-fs、t2-space-p2、3D-TOF FLASH三種序列掃描后,計(jì)算各組圖像信號(hào)噪聲比(SNR)和對(duì)比噪聲比(CNR),并分析比較其圖像質(zhì)量。結(jié)果 :t1-vibe-fs、t2-space-p2兩種序列圖像的SNR與CNR均高于3D-TOF FLASH序列(P均0.05),t1-vibe-fs序列圖像的SNR高于t2-space-p2序列(P0.05),CNR低于t2-space-p2序列(P0.05)。t1-vibe-fs、t2-space-p2兩種序列的圖像質(zhì)量評(píng)分均高于3D-TOF FLASH序列(P均0.05),t2-space-p2序列的圖像質(zhì)量評(píng)分高于t1-vibe-fs序列(P0.05)。結(jié)論:MRTA技術(shù)能清楚顯示顱神經(jīng)及責(zé)任血管,t1-vibe-fs結(jié)合t2-space-p2對(duì)顱神經(jīng)血管壓迫綜合征有重要價(jià)值。
[Abstract]:Objective: to investigate the application of 3.0T MRTA-MRTA in neurovascular compression syndrome and analyze the advantages and disadvantages of these methods. Methods: 50 patients with hemifacial spasm were scanned by t1-vibe-fst2-space-p2p2D-TOF FLASH. The image signal noise ratio (SNR) and contrast noise ratio (CRR) were calculated, and the image quality was analyzed and compared. Results the SNR and CNR of the two kinds of images were higher than those of 3D-TOF FLASH sequences (P = 0.05) and t2-space-p2 sequences (P < 0.05). T1-vibe-fsst2-space-p2 images had higher image quality scores than those of 3D-TOF FLASH sequences (P < 0.05) and t2-space-p2 sequences (P < 0.05). T1-vibe-fsst2-space-p2 sequences had higher image quality scores than those of 3D-TOF FLASH sequences (P < 0.05). The score was higher than that of t1-vibe-fs sequence (P 0.05). Conclusion it is valuable to display cranial nerves and responsible vessels of cranial nerves and responsible vessels with t2-space-p2 combined with t2-space-p2 in the diagnosis of cranial nerve and vascular compression syndrome.
