摘要
目的 比较不同肠道准备剂对T2WI磁共振直肠高分辨成像图像质量的影响。方法 按入组条件筛选2020年6~12月在某三甲肿瘤专科医院行T2WI磁共振直肠高分辨成像的患者84例,按时间先后顺序前42例患者常规使用开塞露行肠道准备,为对照组;后42例患者使用和爽行肠道准备,为观察组。由同一技师在同一设备使用相同序列行T2WI磁共振直肠高分辨成像,由中心两位具有10年临床诊断经验的正高医师行图像质量评价,得分3分及以上定义为图像满足诊断需要,得分5分为优秀。将优片率(得分5分患者所占比例)与欠佳率(得分1~2分患者所占比例)行统计学分析。结果 对照组5分图像质量4例、占9.52%,图像质量欠佳4例、占9.52%;观察组5分图像质量15例、占35.71%;图像质量欠佳1例、占2.38%。图像质量优片率观察组明显大于对照组,P<0.05;图像质量欠佳率观察组明显小于对照组,P<0.05。结论 使用和爽法行肠道准备较开塞露法能够提高T2WI磁共振直肠高分辨成像图像质量,具有临床可操作性及推广价值。
Objective To compare the effects of different intestinal preparations on the image quality of T2WI highresolution magnetic resonance imaging of rectum. Methods According to the screening criteria, 84 patients who underwent T2WI high-resolution magnetic resonance imaging of rectum in a three-A tumor specialist hospital were selected(from June to December in 2020). In chronological order, the first 42 patients used Kaisailu for bowel preparation and served as the control group, and the last 42 patients used Heshuang for bowel preparation and served as the experimental group. T2WI highresolution magnetic resonance imaging of rectum was performed by the same technician on the same equipment using the same sequence, and the image quality was evaluated by two diagnosticians with senior professional post with 10 years of clinical diagnosis experience. A score of 3 or more is defined as the image quality meets the diagnostic needs, and a score of 5 is defined as the image quality is excellent. The excellent image rate(the proportion of image with a score of 5) and the suboptimal image rate(the proportion of image with a score of 1-2) were statistically analyzed. Results There were 4 cases with excellent image quality(9.52%), 4 cases with suboptimal image quality(9.52%) in control group;15 cases with excellent image quality(35.71%) and 1 cases with suboptimal image quality(2.38%) in experimental group. The rate of excellent image quality in experimental group was significantly higher than that in control group, P<0.05. Conclusion Compared with Kaisailu, the use of Heshuang for intestinal preparations can improve the image quality of T2WI high-resolution magnetic resonance imaging of rectum, which has clinical operability and promotion value.
