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 کاملUrinary bladder: normal appearance and mimics of malignancy at CT urography
The objective of this review article is to learn how to recognize anatomic variants and benign entities that mimic bladder cancer at computed tomography (CT) urography. Building on recent data that suggest that CT urography can be used to diagnose bladder cancer, recognition of anatomic variants and benign entities will help improve radiologists' ability to diagnose bladder cancer.
متن کاملSymptomatic extraperitoneal bladder perforation following transurethral bladder surgery: imaging with ct urography.
An 80 year-old man presented to his primary care physician with painless gross hematuria. He reported having intermittent episodes of pink urine containing small clots for about three months. He was initially treated with a single course of ciprofloxacin for presumed urinary tract infection. His symptoms did not improve with antibiotic therapy and he was then referred to our institution for a c...
متن کاملValue of Magnetic Resonance Urography Versus Computerized Tomography Urography (CTU) in Evaluation of Obstructive Uropathy: An Observational Study
Background Obstructive uropathy is a common public health issue that requires imaging research for providing necessary information. The data is important for determining treatment options, and may influence selective management choices. Objective The aim of the study is to determine whether magnetic resonance urography or computerized tomography urography is the best imaging modality among pa...
متن کاملAssessment of CT urography in the diagnosis of urinary tract abnormalities.
BACKGROUND To evaluate the accuracy of helical computerized tomography urography (CTU) in diagnosing urinary tract disease. METHODS We collected 102 patients who underwent CTU from March 2001 to September 2002. The clinical symptoms of these patients included: flank pain or hematuria, which were clinically suggestive of urinary system disorders. All patients received CT scan with or without i...
