Introduction: Renal dynamic study is a well-established and popular test in routine practice of nuclear medicine. The test is non-invasive, rapid and unique in evaluation of the kidney function. In despite of its clinical values, the parameters derived from renogram are physiologically meaningless. That is due to the fact that renogram is not the true kidney function. From mathematical po...

Objective: An abnormal filtration fraction due to divergence between glomerular filtration rate (GFR) and effective renal plasma flow (ERPF) may lead to different estimations of absolute renal function, depending on the radiopharmaceutical administered. The purpose of this study was to estimate GFR and ERPF by measuring the clearances of technetium-99m diethylenetriamine pentaacetic acid (99mTc...

OBJECTIVE To derive the ethnic factor and validate the modified estimated Glomerular Filtration Rate (eGFR) by Modification of Diet in Renal Disease (MDRD) equation for Chronic Kidney Disease (CKD) patients of Rawalpindi. STUDY DESIGN Cross- sectional study. PLACE AND DURATION OF STUDY Armed Forces Institute of Pathology (AFIP), Rawalpindi, from July 2011 to July 2012. METHODOLOGY A total...

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...
