The regional clearance of 99mTc-diethylenetriamine penta-acetate (99mTc-DTPA) from the lungs was measured in 14 patients with noncardiogenic pulmonary edema, six patients with acute pulmonary edema secondary to heart failure, and 29 normal subjects. The radionuclide was delivered in an aerosol which was inhaled for 120 seconds, and the subsequent decline of radioactivity from the lungs was moni...
OBJECTIVE To assess early nephrotoxicity of CDDP (Cis-diamminedichloroplatinum) manifested by a decline in the glomerular filtration rate (GFR) estimated by plasma two sample clearance method (PSC 2) after 99mTc-DTPA injection. STUDY DESIGN Descriptive study. PLACE AND DURATION OF STUDY Department of Nuclear Medicine, Karachi Institute of Radiotherapy and Nuclear Medicine, Karachi, from Sep...
A 45-year-old man presented with loin pain and burning micturation. He had a positive Bilharzial titre and impaired renal function. Ultrasonography (USG) revealed right hydroureteronephrosis and a thickened bladder wall with areas of calcification. A diuretic 99mTc – DTPA scan (technetium-99m diethylene triamine penta acetic acid) showed features of obstruction in both the kidneys. Cystoscopy s...
OBJECTIVE To evaluate the effect of percutaneous transluminal renal angioplasty (PTRA) on split renal function (SRF) in patients with unilateral atherosclerotic renal artery stenosis (ARAS). METHODS We performed a retrospective analysis of all consecutively examined patients at our centre with significant ARAS undergoing PTRA during 2002-07. A significant ARAS was defined as a lesion with a t...
OBJECTIVE In the literature, there are many reports comparing relative renal function calculated with Tc 99m DTPA and Tc 99m DMSA in adults and children. However, there is no consensus about the results. As there is indeterminacy in the reliability of Tc 99m DTPA for the calculation of the relative renal functions, we retrospectively designed a study to compare the relative renal functions meas...
BACKGROUND Renal scintigraphy using 99mTc-mercaptoacetyltriglycine (99mTc-MAG3) is widely used for the assessment of renal function in humans. However, the application of this method to animal models of renal disease is currently limited, especially in rodents. Here, we have applied 99mTc-MAG3 renal scintigraphy to a mouse model of unilateral ureteral obstruction (UUO) and evaluated its utility...
Determination of creatinine clearance (Ccr) is not a reliable indicator of glomerular filtration rate (GFR), owing to tubular secretion of creatinine. It has been reported that Ccr measurements can approximate true GFR after cimetidine (Ci) administration. In this study, GFR was estimated by Cockcroft and Gault's equation (C(C-G)) based on measurement of plasma creatinine, and Ccr was determine...
AIM The aim of this study was to assess the degree of alterations of renal function by using 99m-technetium dimercaptosuccinic acid ((99m)Tc-DMSA) and 99m-technetium diethylenetriaminepentaacetic acid ((99m)Tc-DTPA) scintigraphy in spinal cord injury (SCI) patients. MATERIAL AND METHODS Twenty-two consecutive SCI (15 paraplegic and 7 tetraplegic) patients (mean age: 49.1±13.4 years) who had n...
