Bone SPECT/CT offers additional information on pelvic insufficiency fractures, especially when there is incomplete formation of the H-sign on planar bone scanning.

Os acromiale is an anatomic variant that in rare cases can cause pain. (99m)Tc-methylene diphosphonate bone scintigraphy with SPECT/CT can play an important role in diagnosing this clinical entity. We present a male football player with shoulder pain secondary to a symptomatic os acromiale, and we demonstrate the findings on bone scanning with limited SPECT/CT that diagnosed this important clinical abnormality.

Although the use of 13 N-ammonia and 18 F-FDG PET shows great promise as a tool for diagnosing heart involvement in inflammatory diseases, it can be equally powerful for following disease progression and treatment outcome. We describe a case in which 18 F-FDG PET was effective in following up the treatment outcome of lupus myocarditis.

Inflammatory breast cancer is a rare and aggressive form of cancer characterized by dermal lymphatic invasion and tumor embolization resulting in erythema and edema. In many cases, by the time of diagnosis there is already distant metastasis. Mammography, sonography, CT, and MRI are usually performed for initial staging; however, PET/CT can also be used for initial staging as it offers additional diagnostic information.
