All these patients underwent non contrast enhanced helical computed tomography (CT) scan.
Although these studies have used excretory urography (IVP) as the reference standard, noncontrast helical computed tomography (CT) appears to be a superior reference standard.[1,2] The authors of this study examined the accuracy of hematuria testing compared with a reference standard of helical CT and attempted to differentiate between dipstick screening and different thresholds of microscopic hematuria.
Objectives: To study the use of helical computed tomography 2-D and 3-D images, and virtual endoscopy in the evaluation of airway disease in neonates, infants and children and its value in lesion detection, characterisation and extension.
Helical computed tomography (Asteion - Toshiba) was used for all patients.
A prospective cohort study evaluated spontaneous passage rates of ureteral calculi by size in 172 patients who were diagnosed by unenhanced helical computed tomography. (2) Investigators found spontaneous passage rates of 87% for 1-mm calculi, 76% for 2- to 4-mm calculi, 60% for 5- to 7-mm calculi, 48% for 7- to 9-mm calculi, and 25% for calculi larger than 9 mm.
Helical computed tomography of the neck with contrast infusion detected a possible vascular hemangioma in the right posterior lateral wall of the subglottic region.
Helical computed tomography (CT) of the neck and chest with three-dimensional reconstruction detected an abnormal communication between the trachea and the esophagus that was consistent with a tracheoesophageal fistula.
Can noncontrast helical computed tomography replace intravenous urography for evaluation of patients with acute urinary tract colic?
