Thirty\u2010two patients were prospectively evaluated by MR imaging using a 1.5\u2010T unit. Based on the results of a barium study and\/or digital examination, a balloon catheter was inserted to the level of the lesion before examination. Both conventional T1\u2010 and T2\u2010weighted images and gadopentetate dimeglumine enhanced fat\u2010suppressed T1\u2010weighted images were obtained for all patients. The kappa statistics were performed for the evaluation of interobserver agreement and the McNemar test was performed for the analysis of staging accuracy. When only T1\u2010 and T2\u2010weighted images were used, 5 of 32 tumors were not detected and the extent of 18 of 32 tumors were unclear. However, when gadopentetate dimeglumine enhanced fat\u2010suppressed imaging was added, 24 of 32 tumors were well defined and only one tumor was not detected. In determining the depth of invasion, the staging accuracy was 72% for conventional imaging and 68% for all images combined. There was no significant difference between with gadopentetate dimeglumine fat\u2010suppressed imaging and conventional imaging (<jats:italic>P<\/jats:italic> &gt; .05). Use of gadopentetate dimeglumine (fat\u2010suppressed imaging) resulted in overestimation of muscular invasion, peri\u2010rectal fat invasion, and adjacent organ invasion in 12 patients, whereas nine patients were overestimated without the use of gadopentetate dimeglumine. In the detection of metastatic lymph nodes, gadopentetate dimeglumine enhanced fat\u2010suppressed imaging also was not useful. Tumor detection was excellent using gadopentetate dimeglumine enhanced fat\u2010suppressed images. However, the accuracy of staging was not improved by obtaining such images.<\/jats:p>","DOI":"10.1002\/jmri.1880060309","type":"journal-article","created":{"date-parts":[[2007,3,16]],"date-time":"2007-03-16T00:02:49Z","timestamp":1174003369000},"page":"465-471","source":"Crossref","is-referenced-by-count":57,"title":["Rectal carcinoma: Prospective comparison of conventional and gadopentetate dimeglumine enhanced fat\u2010suppressed MR imaging"],"prefix":"10.1002","volume":"6","author":[{"given":"Hiromi","family":"Okizuka","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kazuro","family":"Sugimura","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Takeshi","family":"Yoshizako","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yasushi","family":"Kaji","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Akihiko","family":"Wada","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2005,11,17]]},"reference":[{"key":"e_1_2_1_2_2","doi-asserted-by":"publisher","DOI":"10.3322\/canjclin.41.1.19"},{"key":"e_1_2_1_3_2","first-page":"5","article-title":"The clinical staging of rectal cancer","volume":"13","author":"Trepper JE","year":"1987","journal-title":"Int J Radiat Oncol Biol Phys"},{"key":"e_1_2_1_4_2","first-page":"237","article-title":"Rectal cancer: the spectrum of selective surgery","volume":"69","author":"Mason YA","year":"1976","journal-title":"Proc R Soc Med"},{"key":"e_1_2_1_5_2","doi-asserted-by":"publisher","DOI":"10.1136\/gut.18.12.1045"},{"key":"e_1_2_1_6_2","doi-asserted-by":"publisher","DOI":"10.1002\/jmri.1880030207"},{"key":"e_1_2_1_7_2","doi-asserted-by":"publisher","DOI":"10.1097\/00004728-198803000-00006"},{"key":"e_1_2_1_8_2","doi-asserted-by":"publisher","DOI":"10.1148\/radiology.176.3.2389016"},{"key":"e_1_2_1_9_2","doi-asserted-by":"publisher","DOI":"10.1148\/radiology.179.1.2006270"},{"key":"e_1_2_1_10_2","doi-asserted-by":"publisher","DOI":"10.1148\/radiology.190.3.8115616"},{"key":"e_1_2_1_11_2","doi-asserted-by":"publisher","DOI":"10.1002\/jmri.1880030117"},{"key":"e_1_2_1_12_2","doi-asserted-by":"publisher","DOI":"10.1148\/radiology.182.2.1732961"},{"key":"e_1_2_1_13_2","doi-asserted-by":"publisher","DOI":"10.1148\/radiology.181.3.1947098"},{"key":"e_1_2_1_14_2","first-page":"403","article-title":"Staging of rectal cancer: assessment with Gd\u2010DTPA enhanced MR.
