SPECT bone scintigraphy has been shown useful for detecting avascular necrosis (AVN) of the femoral heads. Because the femoral necks project in a 15-20 degree posterior angulation from the coronal plane, the femoral head is partially superimposed upon the acetabulum in standard coronal SPECT images. To avoid this problem, the authors now perform oblique angle reorientation of all hip SPECT studies. This new technique, which allows display of the hip in a more anatomic fashion and better definition of hip abnormalities, is described. No new data acquisition is needed, and only a small amount of extra time is required for reconstruction.
单光子发射计算机断层扫描（SPECT）骨闪烁显像已被证明在检测股骨头缺血性坏死（AVN）方面很有用。由于股骨颈从冠状面以15 - 20度的后倾角突出，在标准冠状面SPECT图像中股骨头部分重叠于髋臼之上。为避免这一问题，作者现在对所有髋关节SPECT研究进行斜角重新定位。本文描述了这项新技术，它能以更符合解剖学的方式显示髋关节，并能更好地明确髋关节异常情况。不需要进行新的数据采集，重建仅需少量额外时间。
