Unenhanced multidetector CT evaluation of urinary stones and secondary signs in pediatric patients.
PURPOSE This retrospective study evaluated the unenhanced multi-detector computed tomography (MDCT) findings of urinary system calculi and the secondary signs associated with ureteral stones in children. MATERIALS AND METHODS The study included 87 children (54 boys, 32 girls) with a mean age of 89 months (range: 5 months to 16 years) who were referred to us from various departments and were e...
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...
متن کاملRadiology 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 کاملDual-energy contrast-enhanced computed tomography for the detection of urinary stone disease.
OBJECTIVES To assess the value of dual-energy contrast-enhanced computed tomography (CT) imaging for the detection of urinary stone disease using dual-source CT. MATERIALS AND METHODS Forty consecutive patients (mean age 46.6 +/- 16.2 years, range 27-85 years) suspected of having urinary stone disease underwent dual-source CT of the urinary tract. A 3-phasic CT scan protocol consisting of a s...
متن کاملUnenhanced Spiral CT in Acute Ureteral Colic: A Replacement for Excretory Urography?
OBJECTIVE To compare the usefulness of unenhanced spiral CT (UCT) with that of excretory urography (EU) in patients with acute flank pain. MATERIALS AND METHODS Thirty patients presenting with acute flank pain underwent both UCT and EU. Both techniques were used to determine the presence, size, and location of urinary stone, and the presence or absence of secondary signs was also evaluated. T...
