In order to investigate the feasibility of the assessment of renal function with 99mTc-MDP, we compared renographical images, renogram patterns and the glomerular filtration rate (GFR) obtained by means of a modified Gates' method and 200 MBq of 99mTc-MDP with those obtained by means of 99mTc-DTPA. Because 19 of 20 patients had malignant tumors in the genitourinary tract, there was no differenc...

Introduction: Glomerular filtration rate (GFR) is the most important measure for early detection of deterioration of renal function. Patients with diabetic nephropathy need to be intensely monitored with GFR value. Many methods are used to estimate the GFR, all having their own advantages and constraints. The correlation of these methods with each other in patients with diabetic nephropathy nee...

Renal artery stenosis (RAS) is the most common cause of secondary hypertension. Preliminary data indicate that aspirin renography with hippurate may be more sensitive for detection RAS. In this study 20 patients with known or suspected RAS underwent aspirin renography (20 mg/kg orally 1 hour before injection of radiotracer) and captopril renography (50 mg orally) with 99mTc-DTPA. Renal an...

Objective: To evaluate the improvement of renal function after pyeloplasty measured by 99mTc-DTPA renography. Materials and Methods: This hospital based quasi experimental study was done in department urology, National Institute Kidney Diseases Urology (NIKDU) Bangladesh Research Rehabilitation for Diabetes, Endocrine Metabolic Disorders (BIRDEM) from July 2014 to December 2020. Sixty patients ...

INTRODUCTION L,L-ethylenedicysteine (EC) is a new carrier of technetium Tc 99m (99mTc) with a lower affinity to plasma albumin in comparison with diethylenetriamine pentaacetic acid (DTPA). We compared 99mTc-EC scan with 99mTc-DTPA scan in diuretic renography for patients with obstructive uropathy. MATERIALS AND METHODS Thirty-three patients with upper urinary tract obstruction were randomly ...

UNLABELLED Antibodies accumulate nonspecifically in infectious foci due to the locally increased vascular permeability. This study describes a method of infection imaging in which 99mTc-DTPA (diethylenetriaminepentaacetic acid) is trapped at the target by a previously administered anti-DTPA monoclonal antibody. DTIn1. METHODS Rats with Staphylococcus aureus-infected calf muscle were injected ...

The present investigation was undertaken to study the kinetics of 99mTc-labelled diethylenetriaminepenta-acetate (DTPA) as compared with inulin and 51Cr-labelled ethylenediaminetetra-acetate (EDTA). Twenty patients with various degrees of decreased renal function were studied. The renal clearance, plasma clearance and volume of distribution of all three tracers were measured after a simultaneou...

OBJECTIVE The aim of this study was to compare the renal function measured with either 99mTc-DTPA or 99mTc-EC dynamic scintigraphies with that measured using 99mTc-DMSA static scintigraphy. METHODS the values of relative renal function measured in 111 renal dynamic scintigraphies performed either with 99mTc-DTPA (55 studies) or with 99mTc-EC (56 studies) were compared with the relative functi...
