To evaluate the feasibility of reducing the injection velocity and volume of contrast agent according to BMI, and the effect of body weight (BW), body surface area\uff08BSA\uff09, body mass index\uff08BMI\uff09\uff0cand blood volume (BV) on aortic contrast enhancement when the voltage of third\u2010generation dual\u2010source CT is selected at 70\u2009KV.\n                    <jats:italic>Methods<\/jats:italic>\n                    . A total of 280 patients selected at 70\u2009KV were randomly divided into an experimental group and a control group. Each group was divided into 7 subgroups according to BMI \u226420, 20\u201321, 21\u201022, 22\u201023, 23\u201024, 24\u201025, and 25\u201326. The experimental group uses 2.3\/2.4\/2.5\/2.6\/2.7\/2.8\/2.9\u2009ml\/s injection speed with 350\u2009mgI\/ml contrast agents according to the subgroups; injection time was fixed at 10\u2009s. In the control group, the fixed injection flow rate was 3.5\u2009ml\/s, time was 12\u2009s with a total of 42\u2009ml. Subjects in both groups were inspected to adaptive prospective ECG\u2010gating sequence scanning, and subjective and objective image quality of the two groups were compared using Student's\n                    <jats:italic>t<\/jats:italic>\n                    \u2010test. BMI, BSA, and BV were calculated from the patient\u2019s body weight and height. We assess the relationship between aortic attenuation and BW, BMI, BV, and BSA using regression analysis or correlation analysis.\n                    <jats:italic>Results<\/jats:italic>\n                    . Significant differences exist in vascular enhancement between the two groups; SNR and CNR of objective image quality in the experimental group were lower than those in the control group (\n                    <jats:italic>P<\/jats:italic>\n                    \u2009&lt;\u20090.05). Both groups had the same subjective image scores (\n                    <jats:italic>P<\/jats:italic>\n                    \u2009&gt;\u20090.05). The number of vessels in the optimal enhancement range counts more in the experimental group than in the control group (\n                    <jats:italic>\u03c7<\/jats:italic>\n                    2 value\u2009=\u2009334.25,\n                    <jats:italic>P<\/jats:italic>\n                    \u2009\uff1c\u20090.05). In the control group, a weak to medium correlation was seen between vascular enhancement and BMI (\n                    <jats:italic>r<\/jats:italic>\n                    \u2009=\u2009\u22120.20), BW (\n                    <jats:italic>r<\/jats:italic>\n                    \u2009=\u2009\u22120.42), BSA (\n                    <jats:italic>r<\/jats:italic>\n                    \u2009=\u2009\u22120.46), and BV (\n                    <jats:italic>r<\/jats:italic>\n                    \u2009=\u2009\u22120.48) (\n                    <jats:italic>P<\/jats:italic>\n                    \u2009\uff1c\u20090.05 for all).\n                    <jats:italic>Conclusions<\/jats:italic>\n                    . Compared to BW, BSA, and BV, a weaker negative correlation exists between vascular enhancement and BMI when ATVS selects 70\u2009KV. However, as a much easier way to operate, the stepped low flow and low\u2010contrast agent injection based on BMI was feasible, and the image quality was more homogenized than that of the control group.\n                  <\/jats:p>","DOI":"10.1155\/2022\/7804015","type":"journal-article","created":{"date-parts":[[2022,7,16]],"date-time":"2022-07-16T14:50:19Z","timestamp":1657983019000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Ladder\u2010Like Low Iodine Delivery Rate Injection Protocols Based on BMI at 70\u2009KV by Automated Tube Voltage Selection in Coronary CTA"],"prefix":"10.1155","volume":"2022","author":[{"given":"Shang","family":"Ge","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jian-Yao","family":"Zhu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Han","family":"Liu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yuan","family":"Chen","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7908-2621","authenticated-orcid":false,"given":"Zhao-Huan","family":"Zhu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2022,7,16]]},"reference":[{"key":"e_1_2_10_1_2","doi-asserted-by":"publisher","DOI":"10.2214\/AJR.07.2653"},{"key":"e_1_2_10_2_2","doi-asserted-by":"publisher","DOI":"10.1007\/s00330-015-4191-4"},{"key":"e_1_2_10_3_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.amjcard.2016.12.028"},{"key":"e_1_2_10_4_2","first-page":"253","article-title":"Automatic tube potential selection with tube current modulation in coronary CT angiography: can it achieve consistent image quality among various individuals?","volume":"16","author":"Wang X.","year":"2018","journal-title":"Experimental and Therapeutic Medicine"},{"key":"e_1_2_10_5_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jcct.2014.07.003"},{"key":"e_1_2_10_6_2","doi-asserted-by":"publisher","DOI":"10.2214\/ajr.07.2765"},{"key":"e_1_2_10_7_2","first-page":"224","article-title":"Prediction of blood volume in normal human adults","volume":"51","author":"Nadler S.
