From these patients, 50 IDUS slices were examined with a\ncongruent relationship with the histologic section of resected tissue. The maximum\nthickening, minimum thickening, maximum\/minimum thickening ratio, and form factor of the\nmedial and lateral margins of the medial hypoechoic layer were determined using diagnostic\nimaging, and the results were compared at sites of cancer spread and non\u2010spread.<\/jats:p><jats:p>Twelve slices were obtained from the site of stenosis, 14 from sites of cancer spread, and 24\nfrom non\u2010spread sites. The maximum thickening, minimum thickening, and maximum\/minimum\nthickening ratio differed significantly between the sites of spread and the non\u2010spread.<\/jats:p><jats:p>The absolute values for wall thickening are useful for diagnosing the presence of intramural\nspread in patients with malignant biliary duct stenosis.<\/jats:p>","DOI":"10.1155\/dte.7.159","type":"journal-article","created":{"date-parts":[[2007,8,30]],"date-time":"2007-08-30T12:42:21Z","timestamp":1188477741000},"page":"159-164","update-policy":"http:\/\/dx.doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Diagnosis of Cancer Spread Using Percutaneous Transhepatic Biliary Cholangioscopy\u2010guided Ultrasonography for Malignant Bile Duct Stenosis"],"prefix":"10.1155","volume":"7","author":[{"given":"Hirokazu","family":"Inoue","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2001,1]]},"container-title":["Diagnostic and Therapeutic Endoscopy"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/downloads.hindawi.com\/archive\/2001\/326194.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1155\/DTE.7.159","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2024,8,7]],"date-time":"2024-08-07T22:49:39Z","timestamp":1723070979000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1155\/DTE.7.159"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2001,1]]},"references-count":0,"journal-issue":{"issue":"3-4","published-print":{"date-parts":[[2001,1]]}},"alternative-id":["10.1155\/DTE.7.159"],"URL":"https:\/\/doi.org\/10.1155\/dte.7.159","archive":["Portico"],"relation":{},"ISSN":["1070-3608","1029-0516"],"issn-type":[{"type":"print","value":"1070-3608"},{"type":"electronic","value":"1029-0516"}],"subject":[],"published":{"date-parts":[[2001,1]]},"assertion":[{"value":"2001-01-01","order":3,"name":"published","label":"Published","group":{"name":"publication_history","label":"Publication History"}}]}}
