CT angiography covering both cervical and cerebral arteries using high iodine concentration contrast material with dose reduction on a 16 multidetector-row system.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
introductionOur aim was to examine the feasibility of a computed tomographic angiography (CTA) protocol using a reduced dose of high-concentration contrast material on a 16 multidetector-row system to visualize both cervical and cerebral arteries in one session.
methodsIn 31 consecutive patients, we performed CTA covering the cervical and cerebral arteries. The patients were assigned to one of three groups: group A, 100 mL of 300 mgI/mL; group B, 80 mL of 370 mgI/mL; and group C, 60 mL of 370 mgI/mL followed by a 30-mL saline flush. Arterial enhancements were quantified by measuring attenuation values of the common carotid artery, internal jugular vein, proximal middle cerebral artery (MCA), basilar artery, and straight sinus on source images. Visualizations of the carotid bifurcation and arteries continuing to the circle of Willis were rated on a three-point grading scale on CTA images for qualitative assessment.
resultsThere were no statistically significant differences in attenuation of all the target vessels among the three groups, with the one exception being a lower attenuation of the MCA in group C than in groups A and B (P < 0.01). Neither were there any significant differences noted among the three groups on the visual assessment.
conclusionUse of a reduced dose of high iodine concentration contrast material may provide an equal degree of image quality for CTA covering the craniocervical region on a 16 multidetector-row system.
