Comprehensive MR Urography Protocol: Equally Good Diagnostic Performance and Enhanced Visibility of the Upper Urinary Tract Compared to Triple-Phase CT Urography
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...
متن کاملDual Energy CT - Analysis of Kidney Stones for Specific PatientTreatment
Regional brain atrophy is a typical structural symptom of Alzheimer's disease (AD). Magnetic resonance imaging (MRl) scans capture brain structure with high resolution and are often processed with automated segmentation and parcellation algorithm like Freesurfer to generate regional measures, llke cortical volume, cortical thickness and surface area, which are widely used as inputs in classific...

15 صفحه اولRadiology Rounds - July 2008 - Dual Energy CT for Renal Stones
Renal colic is a common presentation, with patients complaining of moderate to severe flank pain with or without hematuria. Unenhanced low-dose multidetector CT (MDCT) is recognized as the most accurate examination technique. It shows the precise location and size of renal stones within the kidney, the ureters, and the bladder. If the MDCT examination shows a ureteral stone <5 mm, the stone wil...
متن کاملSplit-Bolus Single-Pass Multidetector-Row CT Protocol for Diagnosis of Acute Pulmonary Embolism
BACKGROUND Currently computed tomography pulmonary angiography (CTPA) has become a widely accepted clinical tool in the diagnosis of acute pulmonary embolism (PE). OBJECTIVES To report split-bolus single-pass 64-multidetector-row CT (MDCT) protocol for diagnosis of PE. PATIENTS AND METHODS MDCT split-bolus results in 40 patients suspicious of PE were analyzed in terms of image quality of ta...
