Renal scintigraphy can provide the valuable split renal function which is not obtainable by other non-invasive measurements. This study was designed to investigate the feasibility of the assessment of relative renal function with Tc-MDP as compared with renal imaging radiotracers used for that purpose. Differential renal functioni.e the contribution of percent that each kidney makes to global r...

The reported incidence of unfused crossed renal ectopia is 1 in 75,000 autopsies. A majority of such cases go unnoticed, as they remain asymptomatic and are found incidentally at autopsy. We have presented such a case for its rarity, unusual presentation and association, and have discussed it in light of the available literature. In this report, a 7-year-old boy was pre-operatively diagnosed as...

We retrospectively compared the results of 67Ga chest scans and 99mTc-DTPA aerosol clearance measurements with those of fiberoptic bronchoscopy in 88 patients infected with the human immunodeficiency virus. Of 100 investigations, a pulmonary infection was diagnosed in 39, mainly Pneumocystis carinii pneumonia and a noninfectious disorder was found in 42, mainly Kaposi's sarcoma and lymphocytic ...

In order to improve on the technique of noninvasive detection of renal artery stenosis, we studied the effects of angiotensin converting enzyme inhibition with captopril on individual kidney hemodynamics and function as assessed by technetium-99m diethylenetriaminepentaacetic acid [( 99mTc]DTPA) renal flow studies and iodine-131 orthoiodohippurate [( 131I]hippuran) renography in experimental Go...

BACKGROUND Clearance of inhaled technetium-labeled diethylenetriamine pentaacetate (99mTc-DTPA) is a marker of epithelial damage and an index of lung epithelial permeability. The aim of this study was to investigate the role of 99mTc-DTPA scan in patients with Idiopathic Pulmonary Fibrosis (IPF). Our hypothesis is that the rate of pulmonary 99mTc-DTPA clearance could be associated with extent o...
