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 ...
OBJECTIVE Our aim was to evaluate whether high-resolution sonography can provide additional information concerning rib lesions compared with radiography or bone scintigraphy. MATERIALS AND METHODS Fifty-eight patients with high-uptake rib lesions seen on bone scintigraphy were selected. Radiography and rib high-resolution sonography were performed on these patients. High-resolution sonography...
The aim of the present study was to assess the predictive value of captopril scintigraphy with the new renal agent 99mTc-ethylenedicysteine (99mTc-EC) for post-interventional improvement in blood pressure. Twelve patients who had persistently high blood pressure with previous demonstration of various degrees of renal artery lesion on angiography were included into the study. Baseline and captop...
BACKGROUND Information on differential renal function following abdominal chemoradiation is limited. This study evaluated the association between renal function as measured by biochemical endpoints and scintigraphy and dose volume parameters in patients with gastrointestinal malignancies. MATERIALS AND METHODS Patients who received abdominal chemoradiation between 2002 and 2009 were identifie...
Contrast-enhanced ultrasound (CEUS) is an emerging technique to evaluate tissue perfusion. Promising results have been obtained in the evaluation of renal perfusion in health and disease, both in human and veterinary medicine. Renal scintigraphy using 99mTc-Mercaptoacetyltriglycine (MAG3) is another non-invasive technique that can be used to evaluate renal perfusion. However, no data are availa...
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...
Objective. To create a ureteral obstruction experimental model that can be proved through (99m)Tc-DTPA renal scintigraphy and histopathological studies, without causing total renal function loss. Materials and Methods. Ten New Zealand white rabbits were submitted to a surgical experiment to create a model of unilateral obstruction to urinary flow. Surgery procedure provided unilateral ureteral ...
