To study the qualitative value of multislice spiral CT (MSCT) dynamic enhancement scanning for solitary nodules (SPN) of the chest. Methods. In this paper, 40 cases of chest nodules (including 25 cases of malignant nodules, 8 cases of inflammatory nodules, and 7 cases of benign nodules) were first scanned to determine the scope of nodules. At the two rates of 5\u2009ml\/s and 3\u2009ml\/s, CT dynamic enhancement scans were performed at the center of the nodule, and the CT values, peak enhancement (PH) and peak time (PT) before and after SPN enhancement, were recorded. It is mainly strengthened, with 80% (20\/25) of net added value between 20 and 60\u2009Hu, and 20% (5\/25) &gt;60\u2009Hu or &lt;20\u2009Hu. The enhancement peak and peak time are (31.31\u2009\u00b1\u200910.62) Hu and 45\u2009s, respectively. The time-density curve (T-DC) showed a slowly rising type; the inflammatory nodules were mainly severely strengthened, with a net increase of &gt;40\u2009Hu. The enhancement peak value is (49.25\u2009\u00b1\u200912.44)\u2009Hu, and the peak time is 80\u2009s and 140\u2009s. There is a characteristic of rising and falling and then rising in the curve. Conclusion. Multislice spiral CT dynamic enhancement scan reflects the dynamic characteristics of chest nodular blood flow, which can be used to noninvasively evaluate and diagnose SPN.<\/jats:p>","DOI":"10.1155\/2021\/2887639","type":"journal-article","created":{"date-parts":[[2021,11,23]],"date-time":"2021-11-23T18:50:21Z","timestamp":1637693421000},"page":"1-8","source":"Crossref","is-referenced-by-count":1,"title":["Application of Multislice Spiral CT Imaging Technology in the Diagnosis of Patients with Chest Sarcoidosis"],"prefix":"10.1155","volume":"2021","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-9169-229X","authenticated-orcid":true,"given":"Hong-Fei","family":"Ma","sequence":"first","affiliation":[{"name":"The First Hospital of Jilin University, Changchun, Jilin Province 130012, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7291-3181","authenticated-orcid":true,"given":"Liang","family":"Chen","sequence":"additional","affiliation":[{"name":"The First Hospital of Jilin University, Changchun, Jilin Province 130012, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","reference":[{"key":"1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jfo.2014.09.009"},{"key":"2","doi-asserted-by":"publisher","DOI":"10.1063\/1.5085430"},{"key":"3","doi-asserted-by":"publisher","DOI":"10.1136\/annrheumdis-2015-eular.4144"},{"key":"4","doi-asserted-by":"publisher","DOI":"10.1142\/s0218127415400398"},{"key":"5","doi-asserted-by":"publisher","DOI":"10.1109\/tmi.2016.2536809"},{"key":"6","doi-asserted-by":"publisher","DOI":"10.1016\/j.future.2018.04.040"},{"key":"7","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pone.0147537"},{"key":"8","doi-asserted-by":"publisher","DOI":"10.1007\/s11277-018-5415-0"}],"updated-by":[{"DOI":"10.1155\/2023\/9856989","type":"retraction","label":"Retraction","source":"retraction-watch","updated":{"date-parts":[[2023,7,12]],"date-time":"2023-07-12T00:00:00Z","timestamp":1689120000000},"record-id":"49765"},{"DOI":"10.1155\/2023\/9856989","type":"retraction","label":"Retraction","source":"publisher","updated":{"date-parts":[[2023,7,12]],"date-time":"2023-07-12T00:00:00Z","timestamp":1689120000000}}],"container-title":["Journal of Healthcare Engineering"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/downloads.hindawi.com\/journals\/jhe\/2021\/2887639.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/jhe\/2021\/2887639.xml","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/jhe\/2021\/2887639.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2021,11,23]],"date-time":"2021-11-23T18:50:23Z","timestamp":1637693423000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.hindawi.com\/journals\/jhe\/2021\/2887639\/"}},"subtitle":[],"editor":[{"given":"Balakrishnan","family":"Nagaraj","sequence":"additional","affiliation":[],"role":[{"role":"editor","vocabulary":"crossref"}]}],"short-title":[],"issued":{"date-parts":[[2021,11,23]]},"references-count":8,"alternative-id":["2887639","2887639"],"URL":"https:\/\/doi.org\/10.1155\/2021\/2887639","relation":{},"ISSN":["2040-2309","2040-2295"],"issn-type":[{"value":"2040-2309","type":"electronic"},{"value":"2040-2295","type":"print"}],"subject":[],"published":{"date-parts":[[2021,11,23]]}}}
