Although computed tomography (CT) pulmonary angiography is the\u00a0diagnostic gold standard, the\u00a0prognostic value of CT-derived radiological markers remains incompletely defined.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Material and methods<\/jats:title>\n                    <jats:p>This retrospective study included 91 patients with APE. CT-derived radiological parameters\u00a0\u2013\u00a0including the\u00a0Qanadli obstruction index (QI), Mastora score, right ventricle\/left ventricle (RV\/LV) ratio, and RV wall thickness\u00a0\u2013\u00a0were evaluated together with clinical severity scores (Pulmonary Embolism Severity Index\u00a0[PESI], and its simplified version\u00a0[sPESI]) and laboratory markers. Associations with disease severity and intensive care unit (ICU) admission were assessed using correlation and receiver operating characteristic (ROC) analyses.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Among the\u00a0patients, 52.7% were female and 27.5% required ICU admission. PESI, sPESI, QI, Mastora score, and RV\/LV ratio were significantly higher in ICU-admitted patients (all p\u00a0&lt;\u00a00.01). QI correlated significantly with PESI (r\u00a0=\u00a00.433), disease severity (r\u00a0=\u00a00.565), D-dimer (r\u00a0=\u00a00.510), and troponin levels (r\u00a0=\u00a00.536) (all p\u00a0&lt;\u00a00.001). The\u00a0Mastora score showed similar significant associations with clinical severity indices, RV\/LV ratio, and laboratory markers. ROC analysis demonstrated that PESI had the\u00a0highest predictive accuracy for ICU admission (area under the\u00a0curve, AUC\u00a0=\u00a00.849), followed by RV\/LV ratio (AUC\u00a0=\u00a00.838), sPESI (AUC\u00a0=\u00a00.791), and both QI and Mastora score (AUC\u00a0=\u00a00.782). Platelet-to-lymphocyte ratio, systemic immune-inflammation index, and RV wall thickness were not significant predictors.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>CT-derived obstruction indices and RV\/LV ratio provide clinically meaningful prognostic information for ICU requirement in APE, particularly when integrated with established clinical severity scores.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.5114\/pjr\/225890","type":"journal-article","created":{"date-parts":[[2026,8,24]],"date-time":"2026-08-24T08:59:18Z","timestamp":1787561958000},"page":"387-395","source":"Crossref","is-referenced-by-count":0,"title":["CT-derived radiological markers for predicting severity and ICU admission in acute pulmonary embolism"],"prefix":"10.5114","volume":"91","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-1430-1571","authenticated-orcid":true,"given":"Ya\u015far","family":"\u0130ncekara","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9216-4285","authenticated-orcid":false,"given":"\u0130brahim","family":"Meral","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8239-4896","authenticated-orcid":false,"given":"\u00d6mer Acat","family":"Acat","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"3061","published-online":{"date-parts":[[2026,8,17]]},"reference":[{"key":"ref-1964579","doi-asserted-by":"crossref","unstructured":"Henkin S, Ujueta F, Sato A, Piazza G.
