Since HCP is not compatible with MRI, HCP measurements were performed within 20 min before and immediately after MRI, without intermittent fluid intake or release by participants. Intraclass correlation coefficients (ICCs) were calculated to validate HCP-VTC against MRI-VTC and to assess repeatability of HCP measurements before and after MRI. Bland\u2013Altman plots were used to assess agreement between relevant HCP- and MRI-VTC-derived parameters. Precision of HCP\u2019s measurement of VTC-derived parameters was determined for each study participant by calculating the coefficients of variation and repeatability coefficients.\n                    <jats:italic>Main results.<\/jats:italic>\n                    Left- and right-ventricular VTC ICCs between HCP and MRI were &gt;0.8 for all study participants, indicating excellent agreement between HCP-VTCs and MRI-VTCs. Mean (range) ICC of HCP right-ventricular VTC versus MRI right-ventricular VTC was 0.94 (0.88\u20130.99) and seemed to be slightly higher than the mean ICC of HCP left-ventricular VTC versus MRI-VTC (0.91 (0.80\u20130.96)). The repeatability coefficient for HCP\u2019s measurement of systolic time (tSys) was 45.0 ms at a mean value of 282.9 \u00b1 26.3 ms. Repeatability of biventricular HCP-VTCs was excellent (ICC 0.96 (0.907\u20130.995)).\n                    <jats:italic>Significance.<\/jats:italic>\n                    Ventricular volume dynamics measured by HCP-VTCs show excellent agreement with VTCs measured by MRI. Since abnormal tSys is a sign of numerous cardiac diseases, the HCP may potentially be used as a diagnostic screening tool.\n                  <\/jats:p>","DOI":"10.1088\/1361-6579\/ad13af","type":"journal-article","created":{"date-parts":[[2023,12,8]],"date-time":"2023-12-08T17:27:42Z","timestamp":1702056462000},"page":"01NT01","update-policy":"https:\/\/doi.org\/10.1088\/crossmark-policy","source":"Crossref","is-referenced-by-count":0,"title":["The hemodynamic cardiac profiler volume-time curves and related parameters: an MRI validation study"],"prefix":"10.1088","volume":"45","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-1874-7201","authenticated-orcid":true,"given":"Maurits K","family":"Konings","sequence":"first","affiliation":[{"name":"University Medical Center Utrecht (UMCU)"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Manuella Al","family":"Sharkawy","sequence":"additional","affiliation":[{"name":"The Surgical Company, Hemologic B.V., Amersfoort,"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3785-4985","authenticated-orcid":true,"given":"Sjoerd M","family":"Verwijs","sequence":"additional","affiliation":[{"name":"Amsterdam University Medical Centers"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9291-9441","authenticated-orcid":true,"given":"Adrianus J","family":"Bakermans","sequence":"additional","affiliation":[{"name":"Amsterdam University Medical Centers, University of Amsterdam"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Martijn","family":"Visscher","sequence":"additional","affiliation":[{"name":"The Surgical Company, Hemologic B.V., Amersfoort,"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Charles L","family":"Hollenkamp","sequence":"additional","affiliation":[{"name":"The Surgical Company, Hemologic B.V., Amersfoort,"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Denise P","family":"Veelo","sequence":"additional","affiliation":[{"name":"Amsterdam University Medical Centers"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3617-3256","authenticated-orcid":true,"given":"Harald T","family":"J\u00f8rstad","sequence":"additional","affiliation":[{"name":"Amsterdam University Medical Centers"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"266","published-online":{"date-parts":[[2024,1,10]]},"reference":[{"key":"pmeaad13afbib1","doi-asserted-by":"publisher","first-page":"20","DOI":"10.15420\/usc.2017:2:2","type":"journal-article","article-title":"Cardiac toxicity of cancer chemotherapy","volume":"11","author":"Asnani","year":"2017","journal-title":"US Cardiol.
