Hence, this study introduces a bismuth nanoparticle (BiNP)\u2010infused electrospun polycaprolactone (PCL) small\u2010diameter graft (i.e., PCL\u2010Bi) for multimodal imaging. Control (aortic autologous), PCL, and PCL\u2010Bi were implanted as abdominal aortic grafts in Sprague\u2010Dawley rats (\n                    <jats:italic>n<\/jats:italic>\n                    = 3 per group) and monitored over 12 weeks using computed tomography (CT), a standard technique for vascular monitoring, and ultrasound\/photoacoustic (US\/PA) imaging, an emerging nonionizing alternative. BiNP infusion reduced fiber diameter and pore area without changing PCL's bulk porosity, thermal, and mechanical properties. In vivo, PCL\u2010Bi maintained high radiopacity on CT (&gt;1000 HU) and strong signal on PA imaging (&gt;4 AU) throughout the study. Radiopacity positively correlated with the PA signal of BiNP (\n                    <jats:italic>R<\/jats:italic>\n                    <jats:sup>2<\/jats:sup>\n                    = 0.9601,\n                    <jats:italic>p<\/jats:italic>\n                    &lt;0.001). All grafts maintained in vivo patency, and at week 12, PCL and PCL\u2010Bi showed comparable endothelialization, cell infiltration, and collagen deposition to control. Both PCL and PCL\u2010Bi showed features consistent with early active remodeling. Overall, our findings suggest that BiNP infusion enables multimodal monitoring via CT and PA imaging without obvious adverse effects on early patency and biological performance. Lastly, PA imaging represents a viable, nonionizing alternative to CT for monitoring radiopaque bioresorbable devices.\n                  <\/jats:p>","DOI":"10.1002\/adhm.71748","type":"journal-article","created":{"date-parts":[[2026,9,21]],"date-time":"2026-09-21T03:47:21Z","timestamp":1789962441000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Computed Tomography\u2010 and Photoacoustic Imaging\u2010Active Bioresorbable Electrospun Bismuth Nanoparticle\u2010Infused Small\u2010Diameter Vascular Grafts"],"prefix":"10.1002","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-5067-0334","authenticated-orcid":false,"given":"Allan John R.","family":"Barcena","sequence":"first","affiliation":[{"name":"Department of Interventional Radiology The University of Texas MD Anderson Cancer Center  Houston Texas USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Joy Vanessa D.","family":"Perez","sequence":"additional","affiliation":[{"name":"Department of Interventional Radiology The University of Texas MD Anderson Cancer Center  Houston Texas USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0009-3439-2026","authenticated-orcid":false,"given":"Marvin R.","family":"Bernardino","sequence":"additional","affiliation":[{"name":"Department of Interventional Radiology The University of Texas MD Anderson Cancer Center  Houston Texas USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6762-1149","authenticated-orcid":false,"given":"Dominic Karl M.","family":"Bolinas","sequence":"additional","affiliation":[{"name":"Department of Interventional Radiology The University of Texas MD Anderson Cancer Center  Houston Texas USA"},{"name":"College of Medicine University of the Philippines Manila  Manila Philippines"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kitz Paul D.","family":"Marco","sequence":"additional","affiliation":[{"name":"Department of Interventional Radiology The University of Texas MD Anderson Cancer Center  Houston Texas USA"},{"name":"College of Medicine University of the Philippines Manila  Manila Philippines"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1546-7565","authenticated-orcid":false,"given":"Kim Claudette J.","family":"Fernandez","sequence":"additional","affiliation":[{"name":"Department of Interventional Radiology The University of Texas MD Anderson Cancer Center  Houston Texas USA"},{"name":"College of Medicine University of the Philippines Manila  Manila Philippines"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7590-5846","authenticated-orcid":false,"given":"Archana","family":"Mishra","sequence":"additional","affiliation":[{"name":"Department of Interventional Radiology The University of Texas MD Anderson Cancer Center  Houston Texas USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5998-6423","authenticated-orcid":false,"given":"Erin Marie D.
