Emission computed tomography is a new, useful imaging technique; when a rotating gamma camera capable of such imaging is used multiple adjacent transverse sections may be obtained simultaneously, from which coronal and sagittal sections may be computed. The technique was used in a man undergoing urological investigation in whom excretion urography indicated a space-occupying lesion in the left kidney. Ultrasonography and radionuclide imaging showed nothing abnormal, but emission computed tomography using a rotating gamma camera showed that functioning cortical tissue extended across the middle of the left kidney. Radiographs were therefore reviewed and ultrasonography repeated, and it was concluded that the abnormality was a hypertrophied column of Bertin. Emission tomographic imaging of the kidney is a useful adjunct to other non-invasive studies.
发射计算机断层扫描是一种新型的、有用的成像技术；当使用能够进行这种成像的旋转γ相机时，可以同时获得多个相邻的横断面，由此可以计算出冠状面和矢状面。该技术用于一名接受泌尿外科检查的男性患者，排泄性尿路造影显示左肾有占位性病变。超声检查和放射性核素成像未显示异常，但使用旋转γ相机的发射计算机断层扫描显示，功能正常的皮质组织延伸至左肾中部。因此复查了X光片并再次进行超声检查，得出结论该异常为贝廷柱肥大。肾脏的发射断层成像对于其他非侵入性检查是一种有用的辅助手段。
