We aimed to quantify PTT in routine cardiovascular magnetic resonance imaging perfusion sequences. PTT may help in the diagnostic assessment and characterization of patients with unclear dyspnoea or heart failure (HF).<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Methods and results<\/jats:title>\n                  <jats:p>We evaluated routine stress perfusion cardiovascular magnetic resonance scans in 352 patients, including an assessment of PTT. Eighty-six of these patients also had simultaneous quantification of N-terminal pro-brain natriuretic peptide (NTproBNP). NT-proBNP is an established blood biomarker for quantifying ventricular filling pressure in patients with presumed HF. Manually assessed PTT demonstrated low inter-rater variability with a correlation between raters &amp;gt;0.98. PTT was obtained automatically and correctly in 266 patients using artificial intelligence. The median PTT of 182 patients with both left and right ventricular ejection fraction &amp;gt;50% amounted to 6.8 s (Pulmonary transit time: 5.9\u20137.9 s). PTT was significantly higher in patients with reduced left ventricular ejection fraction (&amp;lt;40%; P &amp;lt; 0.001) and right ventricular ejection fraction (&amp;lt;40%; P &amp;lt; 0.0001). The area under the receiver operating characteristics curve (AUC) of PTT for exclusion of HF (NT-proBNP &amp;lt;125 ng\/L) was 0.73 (P &amp;lt; 0.001) with a specificity of 77% and sensitivity of 70%. The AUC of PTT for the inclusion of HF (NT-proBNP &amp;gt;600 ng\/L) was 0.70 (P &amp;lt; 0.001) with a specificity of 78% and sensitivity of 61%.<\/jats:p>\n               <\/jats:sec>\n
