Knowledge regarding previous surgery is important when reporting abdominopelvic CT. We have examined 50 consecutive patients undergoing abdominopelvic CT to establish whether careful scrutiny of the images can reliably reveal evidence of previous surgery. The radiologist performing the CT study inspected the patient's abdomen for scars and established their nature by discussion with the patient. A second radiologist, unaware of the patient's clinical details, reviewed the CT images and predicted whether there had been any previous surgery. These predictions proved inaccurate: Only 51% of scars were recognised at this initial assessment (63% following retrospective review). Although the absence of major organs was reliably reported, even large paramedian scars were missed. Old scars were missed more frequently than recent ones. Accurate details of previous surgery are necessary when interpreting abdominopelvic CT.
在报告腹部盆腔CT时，了解既往手术情况很重要。我们检查了50例连续接受腹部盆腔CT检查的患者，以确定仔细查看图像是否能可靠地发现既往手术的证据。进行CT检查的放射科医生检查患者腹部有无瘢痕，并通过与患者讨论确定其性质。另一位不了解患者临床细节的放射科医生复查了CT图像，并预测患者既往是否接受过手术。这些预测被证明是不准确的：在最初评估时，只有51%的瘢痕被识别出来（回顾性复查后为63%）。尽管主要器官的缺失得到了可靠报告，但即使是较大的旁正中瘢痕也被遗漏了。陈旧性瘢痕比近期瘢痕更容易被遗漏。在解读腹部盆腔CT时，既往手术的准确细节是必要的。
