Our aim was to use texture analysis of pulmonary emboli derived from thoracic computed tomography for prediction of mortality and prognosis of acute pulmonary embolism (PE). Overall, 216 patients (116 female, 53.7%) were included in the analysis. Texture analysis was calculated on axial slices of the contrast enhanced pulmonary angiography of the proximal embolus. Clinical scores, serological parameters, need for intubation, intensive care unit (ICU) admission and mortality was assessed and correlated with the texture features. In the correlation analysis, there were several associations with mortality in days, the highest for the parameter S(0,5)SumVarnc ( r = \u22120.43, P < 0.001). Another parameter, S(3,\u22123)AngScMom correlated with sepsis-related organ failure assessment score (SOFA)-score ( r = 0.31, P < 0.001). Several texture features correlated with venous lactate and glucose levels. In discrimination analysis, there were significant differences in regard to texture features between survivors and non-survivors and between patients with and without the need for ICU admission ( P = 0.02, respectively). These results highlight the potential clinical benefit of texture features in patients with acute PE as novel imaging biomarkers. Further studies are needed to validate these results. <\/jats:p>","DOI":"10.1177\/00033197221111862","type":"journal-article","created":{"date-parts":[[2022,8,17]],"date-time":"2022-08-17T01:17:45Z","timestamp":1660699065000},"page":"461-471","update-policy":"http:\/\/dx.doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":0,"title":["Computed Tomography Embolus Texture Analysis as a Prognostic Marker of Acute Pulmonary Embolism"],"prefix":"10.1177","volume":"74","author":[{"given":"Jakob","family":"Leonhardi","sequence":"first","affiliation":[{"name":"Department of Diagnostic and Interventional Radiology, University of Leipzig, Leipzig, Germany"}]},{"given":"Nikolaos","family":"Bailis","sequence":"additional","affiliation":[{"name":"Department of Diagnostic and Interventional Radiology, University of Leipzig, Leipzig, Germany"}]},{"given":"Marianne","family":"Lerche","sequence":"additional","affiliation":[{"name":"Department of Respiratory Medicine, University Hospital Leipzig, University of Leipzig, Leipzig, Germany"}]},{"given":"Timm","family":"Denecke","sequence":"additional","affiliation":[{"name":"Department of Diagnostic and Interventional Radiology, University of Leipzig, Leipzig, Germany"}]},{"ORCID":"http:\/\/orcid.org\/0000-0002-9273-3943","authenticated-orcid":false,"given":"Alexey","family":"Surov","sequence":"additional","affiliation":[{"name":"Department of Radiology and Nuclear Medicine, Otto von Guericke University, Magdeburg, Germany"}]},{"ORCID":"http:\/\/orcid.org\/0000-0001-8489-706X","authenticated-orcid":false,"given":"Hans-Jonas","family":"Meyer","sequence":"additional","affiliation":[{"name":"Department of Diagnostic and Interventional Radiology, University of Leipzig, Leipzig, Germany"}]}],"member":"179","published-online":{"date-parts":[[2022,8,16]]},"reference":[{"key":"bibr1-00033197221111862","doi-asserted-by":"publisher","DOI":"10.1111\/imj.14145"},{"key":"bibr2-00033197221111862","doi-asserted-by":"publisher","DOI":"10.1016\/S0140-6736(16)30514-1"},{"key":"bibr3
