The Clinical Value of Serial Radionuclide Gastric-Emptying Scintigraphy for Objective Evaluation of Gastroparesis in a Patient with Superior Mesenteric Artery Syndrome Post Corrective Surgery.

Superior mesenteric artery syndrome is a rare cause of intestinal obstruction. The condition results from compression of the duodenum between the aorta and the superior mesenteric artery, which causes an impairment of gastric emptying and associated chronic symptoms. There is a need to objectively assess the severity of gastric-emptying disorder in these patients post-treatment to assess the efficacy of the conservative or surgical management.

Dual-tracer radionuclide imaging in hyperparathyroidism: thallium-201 parathyroid scintigraphy revisited.

Objectives: Tc-sestamibi is the current radiopharmaceutical of choice for the localization of hyperactive lesions of the parathyroid glands in patients with hyperparathyroidism. However, there are multiple factors that adversely affect the accumulation and retention Tc-sestamibi in the hyperfunctioning parathyroid tissue, resulting in a false-negative scan. The objective of this study was to investigate the possibility of an incremental diagnostic role of thallium-201 parathyroid scintigraphy in patients with presumably false-negative Tc-sestamibi scan results.

Pyomyositis mimicking osteomyelitis detected by SPET/CT.

Pyomyositis is a relatively infrequent, sub-acute primary bacterial muscle infection, which due to its non specific clinical findings is unlikely to be early diagnosed especially in diabetic patients. This diagnostic delay may be fatal. Therefore, early diagnosis and prompt treatment are imperative.
