T1\u2010 and T2\u2010weighted images of the upper abdomen and pelvis were obtained before and after oral administration of OMR at doses of 100\u2013400 mg of iron in 300\u2013600 mL of water. Respiratory\u2010ordered phase encoding and presaturation pulses were used routinely for artifact suppression. All dose levels of OMR provided marking of the bowel by increasing intraluminal signal intensity; however, the degree and percentage of small bowel opacification appeared more prominent at higher dose levels of iron. Semisolid or watery bowel movements were noted in 31% of subjects, but no clinically important laboratory abnormalities were seen. OMR improved delineation of the head of the pancreas on T1\u2010weighted images in 72% of subjects but was less useful in defining the body and tail. OMR is a safe and effective bowel contrast agent for MR imaging. Because artifacts due to movement of hyperintense bowel may degrade the images, OMR may be most useful on short TR\/TE or fast imaging pulse sequences or when combined with antiperistaltic agents.<\/jats:p>","DOI":"10.1002\/jmri.1880020105","type":"journal-article","created":{"date-parts":[[2007,3,6]],"date-time":"2007-03-06T01:35:40Z","timestamp":1173144940000},"page":"25-34","source":"Crossref","is-referenced-by-count":17,"title":["OMR, a positive bowel contrast agent for abdominal and pelvic MR imaging: Safety and imaging characteristics"],"prefix":"10.1002","volume":"2","author":[{"given":"Randall M.","family":"Patten","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Albert A.","family":"Moss","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Theresa A.","family":"Fenton","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sharon","family":"Elliott","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2005,11,17]]},"reference":[{"key":"e_1_2_1_2_2","doi-asserted-by":"publisher","DOI":"10.1148\/radiology.149.1.6611926"},{"key":"e_1_2_1_3_2","doi-asserted-by":"publisher","DOI":"10.1016\/0730-725X(85)90009-8"},{"key":"e_1_2_1_4_2","doi-asserted-by":"publisher","DOI":"10.2214\/ajr.148.6.1259"},{"key":"e_1_2_1_5_2","doi-asserted-by":"publisher","DOI":"10.2214\/ajr.150.4.817"},{"key":"e_1_2_1_6_2","first-page":"839","article-title":"Magnetite albumin suspension: a superparamagnetic oral MR contrast agent","volume":"147","author":"Idder DL","year":"1987","journal-title":"AJR"},{"key":"e_1_2_1_7_2","doi-asserted-by":"publisher","DOI":"10.1148\/radiology.164.1.3588924"},{"key":"e_1_2_1_8_2","doi-asserted-by":"publisher","DOI":"10.3109\/02841858909174663"},{"key":"e_1_2_1_9_2","doi-asserted-by":"publisher","DOI":"10.1148\/radiology.175.3.2343116"},{"key":"e_1_2_1_10_2","doi-asserted-by":"publisher","DOI":"10.1148\/radiology.178.2.1987615"},{"key":"e_1_2_1_11_2","doi-asserted-by":"publisher","DOI":"10.1148\/radiology.178.3.1994417"},{"key":"e_1_2_1_12_2","doi-asserted-by":"publisher","DOI":"10.1016\/0730-725X(90)90136-P"},{"key":"e_1_2_1_13_2","first-page":"740","volume-title":"Book of abstracts: Society of Magnetic Resonance in Medicine 1990","author":"Watanabe T","year":"1990"},{"key":"e_1_2_1_14_2","doi-asserted-by":"publisher","DOI":"10.2214\/ajr.156.2.1898792"},{"key":"e_1_2_1_15_2","doi-asserted-by":"publisher","DOI":"10.1002\/mrm.1910080306"},{"key":"e_1_2_1_16_2","first-page":"13086","volume":"52","year":"1987","journal-title":"Federal Register.
