Tc-99m ethylcysteinate dimer brain SPECT perfusion imaging in ictal nonepileptic visual hallucinations.
Visual hallucinations can occur within the central nervous system and may be associated with a lesion anywhere in the visual pathway. The purpose of this study was to assess "ictal" regional cerebral blood flow with Tc-99m ethylcysteinate dimer (ECD) SPECT in patients having acute hallucinations, and to compare the findings to the "interictal" state. ⋯ This prospective preliminary study suggests that brain imaging using SPECT may be useful in identifying the mechanisms and evolution of blood flow abnormalities in certain subgroups of patients who have visual hallucinations and may assist in the selection of specific therapy.

Comparative StudyComparison of Tc-99m methylene diphosphonate, Tc-99m human immune globulin, and Tc-99m-labeled white blood cell scintigraphy in the diabetic foot.
The aims of this prospective study were to evaluate the contribution of Tc-99m methylene diphosphonate (MDP), Tc-99m human immune globulin (HIG), and Tc-99m white blood cell (WBC) to the diagnosis of osteomyelitis in the diabetic foot and to evaluate the surgical or medical therapy with Tc-99m HIG and Tc-99m WBC scans. ⋯ These results show that four-phase bone scintigraphy with early Tc-99m WBC scanning is preferred for detecting osteomyelitis of the diabetic foot. To evaluate the response to therapy, Tc-99m WBC scans are the preferred method, but if this is not available, Tc-99m HIG scanning can be used.

Case ReportsAsymptomatic large main pulmonary artery thromboembolism with a low-probability ventilation-perfusion lung scan.
The incidence of the interpretation of low-probability lung scans in asymptomatic patients with large central pulmonary embolisms and the prognostic implication of the ventilation-perfusion scan appearance in this clinical setting is not documented.
