Comparative StudyEndocrine neoplasm scintigraphy: added value of fusing SPECT/CT images compared with traditional side-by-side analysis.
Positron emission tomography (PET)/computed tomography (CT) imaging integrates physiology and anatomy, providing a powerful dual-modality approach. Analogously, fusing independently acquired single photon emission computed tomography (SPECT) and CT images can overcome interpretive challenges in characterizing and localizing abnormalities by either modality alone, potentially enhancing diagnostic confidence. This study explores the added value of SPECT/CT image fusion compared with traditional "side-by-side" SPECT/CT image review for a variety of endocrine neoplasms. ⋯ CT correlation can be helpful in interpreting endocrine neoplasm SPECT imaging. SPECT/CT image fusion outperformed "side-by-side" SPECT/CT analysis for neoplasm anatomic localization and diagnostic confidence. Therefore, SPECT/CT fusion should be performed routinely because it potentially influences clinical decision-making and patient management.

Case ReportsThe scintigraphic appearance of de Quervain tenosynovitis.
The purpose of this study is to describe the scintigraphic pattern of de Quervain tenosynovitis, a common inflammatory condition of the thumb tendon sheaths related to repetitive use. ⋯ Bone scanning appears to be of value in the differential diagnosis of dorsolateral wrist pain when clinical findings are nondiagnostic. The scintigraphic appearance of de Quervain tenosynovitis can help to confirm the diagnosis while excluding other causes of wrist pain. Determining the sensitivity and specificity of this pattern will require further research.

Comparative StudyA study comparing SPECT and MRI in patients with anosmia after traumatic brain injury.
The initial or first clinical presentation of altered sensation of smell is directly linked to the degree of impaired sensitivity. We took the opportunity to examine normal and nonspecific MRI findings in 6 patients with known anosmia after traumatic brain injury with perfusion SPECT brain imaging. ⋯ This study identified altered blood perfusion pattern in otherwise normal anatomic structures on MRI.
