Twenty-five patients with solitary cold thyroid nodules (SCN) were studied by fine needle aspiration (FNA) cytology, radionuclide perfusion scanning (RPS) and pentavalent technetium dimercaptosuccinic acid (99m Tc DMSA) scanning, with an aim to distinguish neoplastic from non-neoplastic nodules. All the patients were operated upon and the nodules were subjected to histopathological examination....

Noninvasive analysis of renal function in conscious mice is necessary to optimize the use of mouse models. In this study, we evaluated whether single photon emission-computed tomography (SPECT) using specific radionuclear tracers can be used to analyze changes in renal proximal tubule functions. The tracers included (99m)TC- dimercaptosuccinic acid ((99m)Tc-DMSA), which is used for cortex imagi...

Presence of multiple calculi in ureterocele is rare in children. A 6-year-old boy presented with hematuria in whom on x-ray and ultrasound multiple calculi were noted in the urinary bladder. At surgery a ureterocele containing multiple calculi was found. The postoperative (99m) Tc-Dimercaptosuccinic acid scan (DMSA) reported normal renal function.

AIM: To evaluate the clinical utility of hepatic clearance (HC) measured with technetium-99m-diethylenetriaminepenta-acetic acid-galactosyl human serum albumin (Tc-GSA) single-photon emission computed tomography (SPECT) to estimate the degree of liver

The intrathoracic kidney is one of the rare causes congenital ectopic kidney. present study discusses a case referred to our clinic with pre-diagnosis renal agenesis and diagnosis 9-year-old patient who applied complaining abdominal pain. left could not be shown in ultrasonography for patient's In Tc-99m dimercaptosuccinic acid (DMSA) scintigraphy performed on this, was detected far above its n...

Key words: hyperparathyroidism-radionuclide-imaging; primary and secondary hyperparathyroidism [1–3]. With hyperplastic parathyroid glands tetrofosmin hyperplasia; Technetium-99m-diagnostic use; tetrofosmin imaging gives an overall sensitivity of 84% and a specificity of 75%, higher than those of Tc-99m sestam-ibi, ultrasonography and magnetic resonance imaging Renal history [1–2]. The former h...

We present an autopsy case of primary leptomeningeal melanoma visualized with technetium-99m-hexamethylpropyleneamine oxime (Tc-99m-HMPAO) single photon emission CT (SPECT) of the brain. Increased uptake of Tc-99m-HMPAO coincided with leptomeningeal enhancement on MR images and with the tumor location of the autopsy findings. It was thought that Tc-99m-HMPAO could correlate closely with melanom...

Thirty patients had bone scintigraphy with both Tc-99m pyrophosphate (Tc-PPi) and Tc-99m diphosphonate (Tc-HEDP). The images were given a composite rating for quality and the basis of three sets of criteria, and were also compared for the number of lesions detected by each agent. The two agents provided no difference in scan quality. Nevertheless, in ten of the 30 patients, at least two of the ...
