The aim of the present study was to compare lung MRI findings, including T1 and T2 mapping, in a group of n = 11 patients with COVID-19 pneumonia who underwent a scheduled cardiac MRI, and a cohort of healthy controls. MRI scout images were used to identify affected and remote lung regions within the patients\u2019 cohort and appropriate regions of interest (ROIs) were drawn accordingly. Both lung native T1 and T2 values were significantly higher in the affected areas of patients with COVID-19 as compared to the controls (1375 ms vs. 1201 ms, p = 0.016 and 70 ms vs. 30 ms, p &lt; 0.001, respectively), whereas no significant differences were detected between the remote lung parenchyma of the COVID-19 patients and the controls (both p &gt; 0.05). When a larger ROI was identified, comprising the whole lung parenchyma within the image irrespective of the affected and remote areas, the COVID-19 patients still retained higher native T1 (1278 ms vs. 1149 ms, p = 0.003) and T2 values (38 ms vs. 34 ms, p = 0.04). According to the receiver operator characteristics curves, the T2 value of the affected region retained the higher accuracy for the differentiation of the COVID-19 patients against the controls (area under the curve 0.934, 95% confidence interval 0.826\u20130.999). These findings, possibly driven by the ability of MRI tissue mapping to detect ongoing inflammation in the lungs of patients with COVID-19, suggest that T1 and T2 mapping of the lung is a feasible approach in this clinical scenario.<\/jats:p>","DOI":"10.3390\/jimaging8120314","type":"journal-article","created":{"date-parts":[[2022,11,24]],"date-time":"2022-11-24T02:25:36Z","timestamp":1669256736000},"page":"314","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Characterization of COVID-19-Related Lung Involvement in Patients Undergoing Magnetic Resonance T1 and T2 Mapping Imaging: A Pilot Study"],"prefix":"10.3390","volume":"8","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4865-0454","authenticated-orcid":false,"given":"Giovanni","family":"Camastra","sequence":"first","affiliation":[{"name":"Covid-Cardiology Unit, Madre Giuseppina Vannini Hospital, 00177 Rome, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1410-6845","authenticated-orcid":false,"given":"Luca","family":"Arcari","sequence":"additional","affiliation":[{"name":"Covid-Cardiology Unit, Madre Giuseppina Vannini Hospital, 00177 Rome, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5284-3569","authenticated-orcid":false,"given":"Federica","family":"Ciolina","sequence":"additional","affiliation":[{"name":"Radiology Unit, Madre Giuseppina Vannini Hospital, 00177 Rome, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Massimiliano","family":"Danti","sequence":"additional","affiliation":[{"name":"Radiology Unit, Madre Giuseppina Vannini Hospital, 00177 Rome, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Gerardo","family":"Ansalone","sequence":"additional","affiliation":[{"name":"Covid-Cardiology Unit, Madre Giuseppina Vannini Hospital, 00177 Rome, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Luca","family":"Cacciotti","sequence":"additional","affiliation":[{"name":"Covid-Cardiology Unit, Madre Giuseppina Vannini Hospital, 00177 Rome, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Stefano","family":"Sbarbati","sequence":"additional","affiliation":[{"name":"Radiology Unit, Madre Giuseppina Vannini Hospital, 00177 Rome, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2022,11,23]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"727","DOI":"10.1056\/NEJMoa2001017","article-title":"A Novel Coronavirus from Patients with Pneumonia in China, 2019","volume":"382","author":"Zhu","year":"2020","journal-title":"N.
