Abstract

The successful application of single photon emission computed tomography (SPECT) techniques to radionuclide evaluation of the skeleton depends on strict quality control measures, recognition of potential artifacts, and the selection of appropriate cases for specific reprocessing techniques. The application of simple image-processing routines to problems of "hot spot" and bladder pixel overflows facilitated a reduction in the technical inadequacy rate from 19% to 2% for SPECT evaluation of 100 hips, as well as improvement in diagnostic image quality in a variety of additional cases.

摘要

单光子发射计算机断层扫描（SPECT）技术在骨骼放射性核素评估中的成功应用取决于严格的质量控制措施、对潜在伪影的识别以及针对特定后处理技术选择合适的病例。将简单的图像处理程序应用于“热点”和膀胱像素溢出问题，有助于将100例髋关节SPECT评估的技术不足率从19%降至2%，并提高了各种其他病例的诊断图像质量。
