nuclear medicine imaging is routinely used for evaluation of perfusion and function of the transplanted kidneys. at present, the radiopharmaceutical of choice for this study in our center is tc 99m-ec. complications of the kidney graft are demonstrable in the early and delayed images. one of these complications is vesicoureteral reflux to the graft or to the native kidneys. we present a 27 year...

Renal scintigraphy is a physio-functional exploration permitting the exploration and assertion of unilateral renal agenesis. We report the case of a patient followed for a right hydronephrosis having revealed an agenesis of the contralateral kidney confirmed by 99mTc-DMSA scintigraphy. Also 99mTc-DTPA scintigraphy allowed the evaluation of the permeability of the urinary tract of the single rig...

Purpose: To evaluate the amalgamation of scintigraphy and sonography techniques in prognosticating renal disease. Methods: All patients were subjected to while 68 underwent ultrasonography. Ninety-six patients’ imaging data was statistically analyzed including 43 females 53 males. Renal U/S reported anatomical anomaly 94.1% versus 85.4% detected by scintigraphy. There 41 out diagnosed with hydr...

abstract background: screening for patients at risk of renal scarring is a challenge in children with acute pyelonephritis (apn). diuretic tc-99m mercaptoacetyltriglycine (mag3) scintigraphy with zero time injection of furosemide (mag3-f0) was observed to display focal parenchymal disorders. the advantages of mag3 include: lower radiation dose and short duration of the test. the aim of this stu...

A 2.5-year-old boy with a history of the previous incidental finding of an ectopic kidney in ultrasonography was referred to our nuclear medicine center for 99mTc-DMSA renal scintigraphy. The scan showed an unusual type of ectopic fused kidneys on the right side of the lower abdomen. In this anomaly, kidneys were fused completely across the medial portion of both upper and lower pole...

Introduction: Renal length measurement is an important diagnostic clue in several urinary tract abnormalities. Although ultra sonography is the most frequent used modality for renal size estimation, renal diameter assessment by 99mTc-DMSA scintigraphy is of great value. By now, pointing to the renal size in the 99mTc-DMSA scintigraphy report has not been recommended by gui...

A 24-year-old man whose clinical features were suggestive of renovascular hypertension was referred for captopril renal scintigraphy. Captopril renal scintigraphy was positive for renovascular hypertension only when the left kidney was analyzed in 2 separate regions. Angiography confirmed severe stenosis (90%) in the upper branch of the left renal artery.

Introduction:The optimal imaging time of a radionuclide scintigraphy is the time at which the organ of interest has the maximum uptake of the injected radionuclide. This study was performed to investigate the maximum uptake time of 99mTc-DMSA in rat renal scan. Methods: Renal scintigraphy was performed with 3 mCi of 99mTc-DMSA. Planar ima...

The authors report and discuss a case of bilateral renal artery stenosis in a hypertensive 9 year-old girl that was first suspected with (99m)Technetium-dimercaptosuccinic acid renal scintigraphy. The scintigraphy showed signs of acute renal failure while the patient was on enalapril for controlling her hypertension. Bilateral renal artery stenosis was confirmed with computed tomography angiogr...

INTRODUCTION This study aimed to ascertain whether nonopacified kidney on excretory urography (also known as intravenous urography [IVU]) indicates nonsalvageability. METHODS We retrospectively reviewed 45 adult patients with chronic unilateral urinary tract obstruction, in whom IVU revealed nonopacified kidney on one side but normal excretion on the contralateral side. Affected kidneys with ...
