Therefore, there is an unmet need to define the imaging features of calcified micro-gastric GISTs to facilitate diagnosis. This study retrospectively analyzed the computed tomography (CT) features of pathologically confirmed calcified micro-gastric GISTs.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Methods<\/jats:title>\n                <jats:p>The medical records (gastroscopy, pre-treatment gastric CT imaging [pre- and post-contrast scans], pathology) of patients with calcified gastric GISTs\u2009&lt;\u20091\u00a0cm in diameter confirmed pathologically after endoscopic submucosal dissection, endoscopic submucosal excavation, or endoscopic full-thickness resection were retrospectively reviewed.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Results<\/jats:title>\n                <jats:p>Seven patients had 8 calcified gastric GISTs\u2009&lt;\u20091\u00a0cm in diameter.

Lesions had a mean diameter of 5.2\u00a0mm (range, 1.3\u00a0mm\u2009~\u20097\u00a0mm). Unenhanced CT scans showed spots and high-density nodular calcifications in 3 submucosal lesions, 2 lesions in the muscularis propria, and 3 subserosal lesions that protruded outside the stomach. Among the 8 lesions, only two had solid soft tissue components surrounding the calcification, with one of these two showing post contrast enhancement of the solid soft tissue component.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Conclusions<\/jats:title>\n                <jats:p>Novel CT features of gastric GISTs included: commonly found in the gastric antrum, small size (&lt;\u20091\u00a0cm in diameter), calcification, few solid soft tissue components, and no abnormal enhancement in most cases.<\/jats:p>\n              <\/jats:sec>","DOI":"10.1186\/s12880-023-01146-8","type":"journal-article","created":{"date-parts":[[2023,11,20]],"date-time":"2023-11-20T16:02:30Z","timestamp":1700496150000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["CT features of calcified micro-gastric gastrointestinal stromal tumors: a case series"],"prefix":"10.1186","volume":"23","author":[{"given":"Li-Jun","family":"Chen","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yue-Dong","family":"Han","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ming","family":"Zhang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2023,11,20]]},"reference":[{"key":"1146_CR1","doi-asserted-by":"publisher","first-page":"1961","DOI":"10.1245\/s10434-018-6505-7","volume":"25","author":"T Nishida","year":"2018","unstructured":"Nishida T, Cho H, Hirota S, Masuzawa T, Chiguchi G, Tsujinaka T.
