Parenchymal mean transit time analysis of 99mTc-DTPA captopril renography.
UNLABELLED Proposed renal hemodynamic mechanisms of captopril suggest that quantitation of renographic retention parameters should help identify patients suspected of having renovascular disease. The parenchymal mean transit time (MTT) is theoretically superior to other measures of retention, but data supporting its superiority are few. METHODS Two groups of subjects were studied with diethyl...
متن کاملSmall urine leak after renal transplantation: detection by delayed 99mTc-DTPA renography--a case report.
This case report involves a 45-y-old woman after cadaveric renal transplantation. The initial renal scan on the first postsurgical day showed normal findings. Subsequently, on the sixth postsurgical day, the patient had decreased urine output; 99mTc-diethylenetriaminepentaacetic acid renal scanning was performed again and did not show definite scintigraphic evidence of a urine leak. The patient...
متن کاملClinical Significance of Scintillation Camera Electronics
Recent advances in collimator design and detector size, combined with radiopharmaceuticals having high photon yield, have resulted in diagnostic tests that may deliver photon fluxes in excess of the levels at which scintillation cameras can process the data. Moreover, these high rates of photon input may im pair certain parameters of image quality (1 ,2). For certain diagnostic tests, such as c...
متن کامل99mTc-DTPA Diuretic Renography with 3 hours late output fraction in the evaluation of hydronephrosis in children.
OBJECTIVE Dynamic renal scintigraphy complemented by late gravity assisted postvoid images to 60 minutes is a frequently used diagnostic test in the evaluation of hydrone¬phrosis. The objective of this study is to evaluate the effectiveness in acquiring images at 180 minutes to calculate the late output fraction (LOF) of 99mTc-DTPA in the diagnosis of ureteropelvic junction obstruction (UPJO). ...
متن کاملAssessment of individual renal function in children using 99mTc-DTPA.
Differential renal function assessment using 99mTc-DTPA was carried out in 12 children aged between 3 weeks and 11 years who had undergone surgical procedures which allowed separate access to the urine output from each kidney. The results correlated well with those obtained by measuring individual kidney creatinine clearances. The best result was obtained using the technique of deconvolution an...
