Abnormal CT scans of the kidney in 176 patients were reviewed to note the contribution of pre-contrast images to the final diagnosis. Pre-contrast images added useful information only when CT was used to detect renal calcification, hemorrhage, or contrast extravasation and need not be obtained routinely.
回顾了176例患者的肾脏CT异常扫描结果，以评估平扫图像对最终诊断的贡献。仅当CT用于检测肾钙化、出血或造影剂外渗时，平扫图像才会提供有用信息，因此无需常规获取。
