Diffusely increased thyroidal uptake of F-18 fluorodeoxyglucose in a patient with non-Hodgkin's lymphoma and Graves' disease.

Increased uptake of F-18 fluorodeoxyglucose (FDG) has been reported in thyroiditis and hypothyroidism. The authors present a case where increased FDG uptake in the thyroid was subsequently corroborated with a pertechnetate scan and thyroid hormone levels to diagnose previously undetected Graves' disease in a patient of non-Hodgkin's lymphoma being followed-up with positron emission tomography for disease recurrence.

Efficacy of indigenously developed single vial kit preparation of 99mTc-ciprofloxacin in the detection of bacterial infection: an Indian experience.

Objective: To investigate the diagnostic efficacy of indigenously developed single vial kit preparation of Tc-ciprofloxacin (Diagnobact) for the detection of orthopedic infections.

Methods: Seventy-seven patients [25 with clinical suspicion of diabetic foot osteomyelitis (DFOM), 25 with orthopedic device-related infection (ODRI) and 27 with tubercular bone infection] underwent three-phase Tc-methylenediphosphonate bone scintigraphy followed by static Tc-ciprofloxacin imaging at 1, 4 and 24 h. Imaging (anterior and posterior views) was performed under a dual-head gamma-camera using a low-energy, high-resolution, parallel-hole collimator.
