This study sought to determine updated conversion factors (k-factors) that would enable accurate estimation of radiation effective dose (ED) for coronary computed tomography angiography (CTA) and calcium scoring performed on 12 contemporary scanner models current clinical cardiac protocols compare these methods the standard chest k-factor 0.014 mSv·mGy−1cm−1. Accurate ED from CT scans is essential meaningfully benefits risks different imaging strategies optimize test protocol selection....
PURPOSE: To determine if simple renal cysts may be accurately characterized with helical computed tomography (CT) during peak levels of enhancement. MATERIALS AND METHODS: Water-filled "cysts" were suspended in varying concentrations iodine solution, meant to simulate enhancement, within an abdominal phantom. Volume-averaging effects minimized by scanning cylindric 5–30-mm a technique (collimation, 5 mm; pitch, 1:1). Axial and techniques then compared, volume-averaging evaluated 10- 20-mm...
The purpose of the study was to develop quantitative and qualitative criteria for diagnosing fatty liver on contrast-enhanced helical CT.Differential liver-spleen attenuation evaluated between 80 120 sec after injection in 76 patients who underwent CT. Unenhanced CT images had earlier established when minus spleen difference less than or equal -10 H (n = 18). Four observers not seen unenhanced used assess presence a five-point Likert scale, geographic areas spared from infiltration, relative...
PURPOSE: To evaluate thin-section computed tomography (CT) performed during the corticomedullary and nephrographic phases of contrast material enhancement in characterization renal masses. MATERIALS AND METHODS: A prospective study 30 patients was undertaken with CT to characterize 31 "indeterminate" In all patients, 5-mm-thick, contiguous, high-tube-current (320-340-mA) scans were obtained through kidneys before (axial mode), (helical mode, 25-second delay, corticomedullary-phase images),...
PURPOSE: To compare the diagnostic accuracy of focused helical computed tomography (CT) with orally administered contrast material that nonfocused CT and intravenously material. MATERIALS AND METHODS: After receiving oral material, 228 patients clinically suspected appendicitis underwent appendiceal (5-mm section thickness, 15-cm coverage in right lower quadrant). Immediately thereafter, entire abdomen pelvis was performed following intravenous administration (abdomen, 7-mm thickness;...

PURPOSE: To evaluate the belief that frequencies of contrast material extravasation and minor, nonidiosyncratic reactions correlate with intravenous injection rates. MATERIALS AND METHODS: Complications 6,660 consecutive injections for computed tomography were prospectively recorded. Ionic (n = 4,851) or nonionic 1,809) was injected at 0.5-4.0 mL/sec. The rate 1.9 mL/sec less in group 1 2,899), 2.0-2.9 2 2,475), 3.0-4.0 3 1,286). RESULTS: (0.6%) did not differ significantly between groups....
To determine the effects of cyst diameter and location (intrarenal, exophytic), renal attenuation, section collimation, computed tomographic (CT) interscanner variability on pseudoenhancement in a phantom model.A customized anthropomorphic was designed to accept 40-, 140-, 240-HU inserts containing intrarenal exophytic 7-, 10-, 15-mm cysts. Each insert were scanned with five different helical CT scanners by using 1.0-1.5-mm, 2.50-3.75-mm, 5.0-mm, 7.0-8.0-mm, 10.0-mm collimation. Means SDs...
We describe the findings of contrast-enhanced gated cardiac CT in 15 patients with 23 incidentally noted ventricular diverticula.Cardiac diverticula most commonly occur left ventricle but have been reported to all chambers heart. Despite reports their rare occurrence, are fairly common undergoing MDCT angiography.

OBJECTIVE. The objective of this article is to assess radiologist concordance in characterizing thyroid nodules using the American College Radiology Thyroid Imaging Reporting and Data System (TI-RADS), focusing on effect experience reader concordance. MATERIALS AND METHODS. Three experienced three less radiologists assessed 150 TI-RADS lexicon. Percent was determined for various endpoints. RESULTS. Interreader five categories 87.2% shape, 81.2% composition, 76.1% echogenicity, 72.9% margins,...
To determine the sensitivity and specificity of computed tomographic (CT) criteria for differentiating benign from malignant stomach lesions in patients with a thickened gastric wall at CT.A radiology department file search revealed 36 CT who underwent double-contrast barium suspension upper gastrointestinal tract examinations within 6 weeks before or after CT. The authors reviewed images without knowledge final radiologic, endoscopic, pathologic findings to degree thickening symmetry,...
Published cardiac CT angiography (CTA) reference measurements for the chambers, aorta, and pulmonary artery (PA) are incomplete compromised by study population, coronary disease (CAD), or its risk factors. The purpose of our was to establish sex-specific normalized ranges chamber size, wall thickness, ejection fraction (EF), aorta PA diameter on CTA in a population without CAD factors.Seventy-six patients (38 men 38 women) known diabetes; hypertension; smoking history; evidence structural...
Preoperative cardiovascular risk stratification before noncardiac surgery is a common clinical challenge. Coronary artery calcium scores from ECG-gated chest computed tomography (CT) imaging are associated with perioperative events. At the time of preoperative evaluation, many patients will not have had CT imaging, but nongated studies performed for variety indications. We evaluated relationships between coronary severity estimated previous and major events (MCE) after surgery.
