<b>Feasibility of MDCT Colonography in Ultra-Low-Dose Technique in the Detection of Colorectal Lesions:</b> Comparison with High-Resolution Video Colonoscopy

Abstract

Despite an effective dose of approximately 1 mSv, MDCT colonography using an ultra-low-dose technique performs as well as MDCT colonography with a standard dose, according to published data. After mathematic noise reduction, 82% of polyps larger than 5 mm can be detected.
