Model-based vs hybrid iterative reconstruction technique in ultralow-dose submillisievert CT colonography

Popis výsledku v původním jazyce

Objective: To compare image quality of different reconstruction techniques in submillisievert ultralow-dose CT colonography (CTC) and to correlate colonic findings with subsequent optical colonoscopy. Methods: 58 patients underwent ultralow-dose CTC. Theimages were reconstructed with filtered back projection (FBP), hybrid iterative reconstruction (HIR) or model-based iterative reconstruction (MBIR) techniques. In each segment, endoluminal noise (expressed as standard deviation of endoluminal density) was measured and image quality was rated on a five-point Likert scale by two independent readers. Colonic lesions were evaluated in consensus and correlated with subsequent optical colonoscopy where possible. Results: The estimated radiation dose was 0.41+/- 0.05mSv for the supine and 0.42 +/- 0.04mSv for the prone acquisitions. In the endoluminal view, the image quality was rated better in HIR, whereas better scores were obtained in MBIR in the cross-sectional view, where the endolumina
