Peripheral pulmonary arteries: optimization of the spiral CT acquisition protocol.
Abstract
PURPOSE: To analyze the influence of collimation on identification of segmental and subsegmental pulmonary arteries on spiral computed tomographic (CT) scans. MATERIAL AND METHODS: Contrast material-enhanced spiral CT scans were retrospectively analyzed. Patients in group A (n = 20) underwent CT with 3-mm collimation, 1.00 second per revolution, and pitch of 1.7; those in group B (n = 20) underwent CT with 2-mm collimation, 0.75 second per revolution, and pitch of 2.0. A total of 800 segmental (20 arteries per patient) and 1,600 subsegmental (40 arteries per patient) arteries were assessed. RESULTS: The mean number of analyzable segmental arteries per patient was greater in group B patients (18.6 of 20.0 [93%]) than that in group A patients (17.0 of 20.0 [85%]) (P < .001). The mean number of analyzable subsegmental arteries per patient was greater in group B patients (24.6 of 40.0 [61%]) than that in group A patients (14.8 of 40.0 [37%]) (P < .0001). Frequency of identification on CT scans of 13 of the 40 subsegmental arteries was improved in group B compared with group A patients (P < .0001). CONCLUSION: Spiral CT with 2-mm collimation at 0.75 second per revolution enables marked improvement in the analysis of segmental and subsegmental pulmonary arteries.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
