OBJECTIVE The goal of this prospective study was to compare the efficiency of two types of MRU after diuretic administration to identify the non-dilated ureter. METHODS MR pelvic examinations were performed in 126 patients after receiving furosemide. Each patient underwent in addition to their protocol for context, two types of MRU: 2D T2-weighted FSE (T2w-MRU) and 3D Gd T1-weighted GE (CE-MR...

The objective of this study was to evaluate the Role of MRU as a single imaging modality in evaluation of Pelvi-ureteric junction obstruction. 40 patients of hydronephrosis suspected to have PUJ obstruction were enrolled for the study from May 2010 to Nov. 2012. All patients under went USG, intravenous Urography (IVU), Glomerular filtration rate (GFR) Calculation by Cockcroft-Gault formula and ...

BACKGROUND Magnetic resonance urography (MRU) is one of the most attractive imaging modalities in paediatric urology, providing largest diagnostic information in a single protocol. Therefore, the aim of our study was to assess the diagnostic value of MRU in children with urogenital anomalies (especially anomalies of the renal pelvis and ureter) and the renal function using different post-proces...

The objective of this study was to compare Magnetic Resonance Urography (MRU) with Intravenous Pyelography (IVP) in evaluation of patients with hydronephrosis on ultrasonography. 49 patients of hydronephrosis on USG were enrolled for the study from Jan. 2011 to Dec. 2012. All patients under went Intravenous Urography (IVU). MRU was done to determine the anatomical details and function of each r...

OBJECTIVE Limited evidence is available on predictors of medical resource utilization (MRU) and related direct costs, especially in treatment-experienced patients infected with genotype 1 hepatitis C virus (HCV). This study aimed at investigating patient and treatment characteristics that predict MRU and related non-drug costs in treatment-experienced patients with chronic hepatitis C (CHC) tre...

OBJECTIVES To prospectively compare the diagnostic performance and the visualization of the upper urinary tract (UUT) using a comprehensive 3.0T- magnetic resonance urography (MRU) protocol versus triple-phase computed tomography urography (CTU). METHODS During the study period (January-2014 through December-2015), all consecutive patients in our tertiary university hospital scheduled by a ur...

Magnetic Resonance Urography (MRU) is increaingly replacing Intravenous Urography (IVU) which has been the traditional modality for uro-imaging. However, the effectiveness and advantages of this new and costly modality need to be proven before defining its place in the uro-radiological armamentarium. We conducted a prospective study to assess the role of MRU in 100 consecutive cases where IVU w...

OBJECTIVE The purpose of this study was to compare the effectiveness of MR urography (MRU) with that of ultrasonography (US) in the evaluation of urinary tract when this failed to opacify during excretory urography (EXU). MATERIALS AND METHODS Twelve urinary tracts in 11 patients were studied. In each case, during EXU, the urinary system failed to opacify within one hour of the injection of c...

The buffer cache management algorithm used by almost all operating systems is known as LRU(Least Recently Used). LRU is known to perform well in applications with irregular reference pattern. However, it shows poor performance for sequential-pattern or looping-pattern applications with large-size data. For sequential or looping reference pattern, MRU(Most Recently Used) replacement policy is fr...
