Single-photon emission computed tomography (SPECT) is a new imaging method that offers the advantage of cross-sectional imaging and improved contrast resolution as compared with conventional planar imaging. Preliminary SPECT studies of the liver for detection of metastatic disease are very promising. However, these studies indicate some potential pitfalls in the interpretation of the normal liver SPECT images. Experience with 58 tomographic studies obtained with a General Electric 400T rotating gamma camera is presented, with special emphasis on the areas of potential misinterpretation and on recognition of the normal anatomy as seen by this technique.
单光子发射计算机断层扫描（SPECT）是一种新的成像方法，与传统平面成像相比，它具有断层成像的优势，且对比分辨率有所提高。利用SPECT对肝脏进行初步研究以检测转移性疾病，前景十分广阔。然而，这些研究表明在解读正常肝脏SPECT图像时存在一些潜在的陷阱。本文介绍了使用通用电气400T旋转伽马相机获得的58例断层扫描研究经验，特别强调了潜在误判区域以及通过该技术所观察到的正常解剖结构的识别。
