To evaluate the feasibility of applying a barium enema-style bowel preparation protocol to CT colonography (CTC) in clinical practice.
11 patients underwent CTC using a simplified bowel preparation protocol based on magnesium citrate, similar to that used for barium enema. Two radiologists assessed the homogeneity of fluid tagging, volume of residual fluid, and degree of colonic distension in six colonic segments (cecum, ascending, transverse, descending, sigmoid, rectum) in both supine and prone positions. Each parameter was rated on a 4-point Likert scale (0 = optimal, 3 = inadequate). The mean score and proportion of segments achieving a score of 0 were calculated.
More than 85% of segments received a score of 0 for tagging uniformity and colonic distension, and over 90% for residual fluid. Mean scores were below 0.3 for all three parameters. These findings indicate that the preparation protocol provided sufficient colonic cleansing and distension comparable to previously reported standard protocols.
A simplified bowel preparation protocol adapted from barium enema practice can be effectively applied to CT colonography, achieving clinically acceptable image quality.
评估在临床实践中将钡灌肠式肠道准备方案应用于CT结肠成像(CTC)的可行性。
11例患者采用基于枸橼酸镁的简化肠道准备方案进行CTC检查,该方案类似于钡灌肠所用方案。两名放射科医生在仰卧位和俯卧位下评估六个结肠段(盲肠、升结肠、横结肠、降结肠、乙状结肠、直肠)的液体标记均匀性、残留液体量和结肠扩张程度。每个参数按4级李克特量表评分(0 = 最佳,3 = 不足)。计算平均得分以及得分为0的结肠段比例。
超过85%的结肠段在标记均匀性和结肠扩张方面得分为0,超过90%的结肠段在残留液体方面得分为0。所有三个参数的平均得分均低于0.3。这些结果表明,该准备方案能提供与先前报道的标准方案相当的充分结肠清洁和扩张效果。
源自钡灌肠实践的简化肠道准备方案可有效应用于CT结肠成像,获得临床可接受的图像质量。
