High contrast to noise ratio (CNR) using CO2 for colonic distension in 3.0 Tesla Magnetic Resonance Colonography (MRC)

چکیده
Purpose / introduction Magnetic Resonance Colonography (MRC) is studied as screening technique for colorectal cancer. The lack of ionizing radiation and the superior contrast resolution over computed tomography (CT) make MRC a valuable alternative to CT-colonography [1]. At present the optimal scan parameters and bowel preparation, aimed at high image quality and minimized patient burden, are not known. Importantly, patient acceptance of MRC is diminished as fluid enemas are used [2]. A strategy using carbon dioxide (CO2) for bowel distension as used in CT-colonography can be expected to lead to far better patient acceptance. The objective for this study is the quantitative assessment of Magnetic Resonance Colonography (MRC) quality at 3.0 Tesla, using CO2 as intraluminal contrast medium.

MR colonography: how does air compare to water for colonic distention?
PURPOSE To prove the feasibility of air-distended magnetic resonance colonography (MRC) and compare it with water-based distention. MATERIALS AND METHODS In five volunteers, the colon was imaged twice: once after distending the colon with air and a second time after distending the colon with water. A total of 50 patients, who had been referred to colonoscopy for a suspected colorectal patholo...

PURPOSE To assess colonic anastomoses in patients after surgical treatment by means of MR colonography (MRC) in comparison with conventional colonoscopy (CC). MATERIALS AND METHODS A total of 39 patients who had previously undergone colonic resection and end-to-end-anastomosis were included in the study. MRI was based on a dark-lumen approach. Contrast-enhanced T1-weighted (T1w) three-dimensi...

BACKGROUND MR coronary angiography (MRCA) has been demonstrated successfully at 3 Tesla (T). However, the advantages remain unclear. No systematic comparison of MRCA between 1.5 T and 3 T has been performed. Therefore, anatomic coverage, image quality, signal-to-noise ratio (SNR), contrast-to-noise ration (CNR), and susceptibility artifacts were compared in 23 subjects. METHODS AND RESULTS Id...

متن کاملColonoscopy detects significantly more flat adenomas than 3-tesla magnetic resonance colonography: a pilot trial.
BACKGROUND AND STUDY AIMS Colorectal cancer (CRC) is one of the most common cancers worldwide, and several efforts have been made to reduce its occurrence or severity. Although colonoscopy is considered the gold standard in CRC prevention, it has its disadvantages: missed lesions, bleeding, and perforation. Furthermore, a high number of patients undergo this procedure even though no polyps are ...
