Current applications and controversies in bone SPECT/CT imaging

Bone scintigraphy is the largest single volume area in nuclear medicine, while PETCT is a close second. Most bone imaging is planar imaging for oncology. Bone SPECT/CT is a dual modality imaging test that has not gained as high a profile as other nuclear medicine techniques such as PETCT, despite recent significant advances in both SPECT/CT technology and availability. There is a remarkable lack of data regarding its indications, potential utility and accuracy. In addition, there is a lack of knowledge among referring clinicians as to how to optimally utilise this technique. SPECT/CT brings challenges in
terms of staff training, radiation protection, imaging protocols and interpretation time, but offers significant advantages in terms of diagnostic accuracy. Many nuclear medicine and radiology departments have upgraded to this technology, without a clear plan for putting the equipment to use, but rather evolving a plan over time. This article is a brief discussion of the utility and indications for bone SPECT/CT.
