Comparative study on enhancement efficiency of T 1 quick3D and T 1 FSE quences of 1.5T MR for pelvic muscle/ZHANG Zhong-yuan, FANG Xin, WEI Chao, et al//China Medical Equipment,2020,17(7):59-62.
[Abstract] Objective: T o explore the enhancement efficiency of T 1 fast spin echo (T 1 FSE) and three-dimensional volume interpolation fast scrambling pha quence (T 1quick 3D) quences of 1.5T magnetic resonance (MR) on pelvic muscle and compare signal to noi ratio (SNR) and contrast noi ratio (CNR) of pelvic muscle post enhancement, so as to lect the optimal enhancement quences of soft tissue. Methods : 120 patients who underwent MR enhancement on pelvic cavity were lected. And they were divided into T 1 quick3D group (60 cas) and T 1FSE group (60 cas) according to the random number table. And T 1 quick3D group received T 1 quick3D group quence enhancement and T 1 FSE group adopted T 1 FSE quence enhancement scan, respectively. The SNR and CNR of the images of two groups at venous pha were measured by adopting region of interest (ROI) with same size. And the enhancement efficiencies of two kinds of quences on pelvic muscle were analyzed and compared. Results: Both two groups had well cooperation, and the successful rates of the enhancement of two kinds of quences were 100%. The results of SNR of the images of T 1 FSE quence and T 1 quick3D q
uence on gluteus maximus of pelvic cavity were 134.31±7.53 and 109.87±6.65, respectively, and the SNR of T 1FSE group was significantly higher than that of T 1 quick3D group (t =18.84, P <0.05). The results of CNR of gluteus maximus of pelvic cavity of the images of T 1 FSE quence and T 1 quick3D quence were 82.51±8.83 and 89.18±8.09, respectively, and the CNR of T 1 FSE group was significantly lower than that of T 1 quick 3D group (t =4.31, P <0.05). Conclusion: When the muscle of pelvic cavity undergoes enhancement scan with the two kinds of quences, both of them can obtain the images quality that satisfies the clinical requirement. The T 1quick 3D enhanced scan has no interlayer spacing, and its scan time only 35s, and it has faster acquisition speed, and it is contributive to implement 3D reconstruction. It is suitable for patients who cannot coordinate with the scan, and it is an important supplement to T 1 FSE enhanced quence.

关于黄鹤楼的诗句
心寒的句子说说心情[摘要] 目的：探讨1.5T磁共振常规T 1加权快速自旋回波(T 1 FSE)成像和三维容积内插快速扰相序列(T 1 quick3D)对盆腔肌肉增强的效能，比较盆腔肌肉增强后肌肉的信噪比(SNR)和对比噪声比(CNR)，以选取最佳软组织增强序列。方法：选取120例行盆腔磁共振增强的检查患者，按随机数表法将其分为T 1 quick3D组和T 1 FSE组，每组60例。T 1 quick3D组采用T 1 quick3D序列增强；T 1 FSE组采用T 1 FSE序列增强扫描。采用同等大小感兴趣区域(ROI)测量两组静脉期图像的SNR和CNR；分析比较两种序列对盆腔肌肉增强的效能。结果：两组患者均配合良好，两种序列扫描增强成功率为100%。T 1 FSE和T 1 quick3D序列图像盆腔臀大肌的SNR分别为134.31±7.53和109.87±6.65，T 1 FSE组的SNR高于T 1 quick3D组，其差异有统计学意义(t =18.84，P ＜0.05)；T 1 FSE组和T 1 quick3D组序列图像盆腔臀大肌的CNR分别为82.51±8.83和89.18±8.09，T 1 FSE组的CNR略低于T 1 quick3D组，其差异有统计学意义(t =4.31，P ＜0.05)。结论：采用两种序列对盆腔肌肉增强扫描时，均可获得满足临床诊断的图像质量，T 1 quick3D增强扫描无层间距，扫描时间仅为35 s，采集速度更快，并有利于三维重建，适合于不能配合扫描的患者，是T 1 FSE增强序列的重要补充。[关键词] 磁共振成像(MRI)；三维容积内插快速扰相序列；信噪比(SNR)；增强效能DOI: 10.3969/J.ISSN.1672-8270.2020.07.015
