UNLABELLED Severe renal artery stenosis (RAS) is a relatively uncommon complication after renal transplantation but is a curable cause of hypertension, which demands reliable early diagnosis to reduce morbidity, mortality and graft loss. Captopril renography has been used for a number of years as a method of detecting RAS but controversy still exists as to the diagnostic accuracy of this test a...

Objective: There exists a variety of methodologies for the quantitation of effective renal plasma flow (ERPF) with 99"'Tc-MAG3, from very accurate in vitro techniques to less accurate, yet reliable and easy gamma camera methods. This study compares a new technique that uses a single blood sample but does not require the preparation of a standard, with the in vitro single sample ERPF determinati...

BACKGROUND Idiopathic retroperitoneal fibrosis (IRF) as an uncommon cause of obstructive uropathy is often primarily treated medically by the attending urologist. We evaluated dynamic enhancement analysis (DEA) as a possible predictor of response to medical treatment and for treatment monitoring. METHODS From 2007, 24 patients with fibrosis were assessed by magnetic resonance imaging (MRI) wi...

UNLABELLED We performed Tc-99m MAG3 dynamic renal scintigraphy followed by a SPECT/CT imaging to a 38-yr-old woman who had a fistula in the lower urinary tract after a gynecological operation for diagnostic purposes. After scintigraphy, CT and fusion images were evaluated, it was observed that the activity in the right lower quadrant was actually in the ileal lumen. When early and late SPECT/CT...

INTRODUCTION To observe the renal function recovery measured by diuretic renography in short and medium follow-up of patients with transperitoneal Anderson-Hynes laparoscopic pyeloplasty. MATERIAL AND METHODS WE PERFORMED A RETROSPECTIVE REVIEW FROM OUR SERIES OF LAPAROSCOPIC PYELOPLASTIES, AND WE APPLIED THE FOLLOWING SELECTION CRITERIA: 1) to have at least two MAG3 diuretic renography durin...

The authors report and discuss a case of bilateral renal artery stenosis in a hypertensive 9 year-old girl that was first suspected with Technetium-dimercaptosuccinic acid renal scintigraphy. The scintigraphy showed signs of acute renal failure while the patient was on enalapril for controlling her hypertension. Bilateral renal artery stenosis was confirmed with computed tomography angiography....

It remains challenging to predict the risk of rupture for a specific atherosclerotic plaque timely, a thrombotic trigger tightly linked to inflammation. CD11b, is a biomarker abundant on inflammatory cells, not restricted to monocytes/macrophages. In this study, we fabricated a probe named as (99m)Tc-MAG3-anti-CD11b for detecting inflamed atherosclerotic plaques with single photon emission comp...
