The estimation of glomerular filtration rate and effective renal plasma flow based on camera-based methods for diagnostic and prognostic are studied by manually ROIs drawing on dynamic renal scintigraphy. The manually ROIs drawing may reduce the convenience and reliability. This paper proposes a estimation of glomerular filtration rate and effective renal plasma flow based on camera-based metho...

PURPOSE To evaluate the effect of sildenafil, administered prior to renal ischemia/reperfusion (I/R), by scintigraphy and histopathological evaluation in rats. METHODS Twenty-four rats were divided randomly into two groups. They received 0.1 ml of 99mTechnetium-etilenodicisteine intravenous, and a baseline (initial) renal scintigraphy was performed. The rats underwent 60 minutes of ischemia b...

A patient with breast metastases is presented showing increased nodular renal uptake of tracer on bone scintigraphy that also demonstrated rib metastases and a large metastasis in the pelvis. However, vertebral body metastases were not shown when clearly demonstrated on CT with even partial compression on a thoracic spine film. Most of the renal lesions were hypoechoic on sonography, showed hyp...

BACKGROUND Renal scintigraphy with radiolabeled pentetic acid (diethylenetriamine pentaacetic acid [DTPA]) or, more recently, mertiatide (mercaptoacetyltriglycine [MAG3]), with or without captopril challenge, is widely recommended as a diagnostic test for renal artery stenosis. OBJECTIVES To address (1) whether the diagnostic accuracy has been improved by the use of captopril and the introduc...

A 35-year-old Asian male presented with complaints of fever, right-sided pleuritic chest pain and shortness of breath of 7 days’ duration, 1 month after a right percutaneous nephrolithotomy (PCNL) by supracostal puncture. On examination, the patient was pale and tachypnaeic with pulse 120/min and blood pressure 150/100mm Hg. He had stony dullness with decreased breath sounds in the right mammar...

Extraadrenal abnormal uptake on adrenocortical scintigraphy has been reported rarely in the normal gallbladder, lipid cell tumor of the ovary, or in clear cell type renal cell carcinoma. Clear cell type renal cell carcinoma contains glycogen and cholesterol like the adrenal gland, but the uptake of the radionuclide I-131 cholesterol has been reported to be low and not sufficient to image it. Ri...

Purpose: To evaluate the suitability of Tc-DTPA as a radiotracer in Persian cat's renal scintigraphy. Methods: twelve adult healthy Persian cats were selected. For scintigraphy, the animals were anesthetized and TC-DTPA was injected via the femoral vein as a bolus at a dose of 1.5 mCi. Immediately after intravenous injection of radiotracer, scintigraphic operation was conducted on the renal org...

We quantitatively evaluated total and individual renal function by technetium-99m mercaptoacetyltriglycine (Tc-99m MAG3) renal scintigraphy before and after radiofrequency ablation (RFA) of renal tumors. Eleven patients who underwent Tc-99m MAG3 renal scintigraphy 1 week before and after RFA were evaluated (7 men and 4 women; age range: 23-83 years; mean age: 60.6 years). Five patients had soli...
