Abstract Although few reports address the use of three-phase bone scanning (TPBS) and {sup 111}In-labeled white blood cell (In-WBC) scintigraphy in hip arthroplasty utilizing a porous coated prosthesis, the literature suggests that scintigraphic patterns in the uncomplicated patient may differ from that seen in the cemented prosthesis. There are three different types of bone scans that can be ordered. Gamma cameras and PET scanners are the 2 basic types of cameras used to image the radioactive decay from the radiotracers utilized in bone scintigraphy. During the bone scan, the tracer gives off a type of radiation called gamma radiation, and a camera . Bone scans can also play an important role in the diagnosis of radiographically occult fractures (such as undisplaced femoral neck fractures) as well as sacral and vertebral insufficiency fractures (Figure 4). For a bone scan with SPECT/CT imaging, a "SPECT" scan is combined with a "CT" scan to help localize an area of abnormal activity that may be present on the planar bone scan image.
