Lower-dose CT urography (CTU) with iterative reconstruction technique in children – initial experience and examination protocol
BACKGROUND Conventional X-ray urography is one of the basic imaging techniques in urinary tract diseases in children. CT urography (CTU) employing standard Filtered Back Projection (FBP) reconstruction algorithms is connected with higher radiation dose. Advanced iterative reconstruction techniques enable lowering the radiation dose to the level comparable with conventional X-ray urography with ...
متن کاملHydronephrosis and pyelonephritis in a pregnant woman: a proposal of MR urography clinical applications
Introduction. MR urography has been used satisfactorily to evaluate kidneys, pelvicaliceal system, ureters and bladder, this technique has the advantage of not using ionizing radiation and also the potential to provide functional information as CT or even more. Case report. We present a case of a 25-years-old pregnant woman with right lumbar pain and probable urolithiasis, the static fluid MR u...
متن کاملComputed Tomographic urography - A boon to renal enigma
Objective: Patients with suspected urinary tract disease are often referred for multiple studies such as excretory urography (EU), ultrasound (US), computed tomography (CT) or magnetic resonance imaging (MRI). With the recent development of multislice helical CT, many institutions have started to evaluate the use of CT as a single imaging test that partially or completely replaces EU. This stud...
متن کاملFast System Matrix Calculation in CT Iterative Reconstruction
Introduction: Iterative reconstruction techniques provide better image quality and have the potential for reconstructions with lower imaging dose than classical methods in computed tomography (CT). However, the computational speed is major concern for these iterative techniques. The system matrix calculation during the forward- and back projection is one of the most time- cons...
متن کاملA Child with Recurrent Urinary Tract Infection: Case Report
Introduction: In paediatric practice, the underlying anatomical abnormalities of urinary tract need to be considered in recurrent urinary tract infection. Case Report: A 5 year old girl presented with recurrent urinary tract infection. Ultrasonography revealed rounded anechoic lesion at the vesicle base continuous with dilated tubular structure inferolaterally to the left side of bladder sugges...
