Values are n/N (%), median (range), or mean ± SD.

FPP = first-pass perfusion; LGE = late gadolinium enhancement; NA = not applicable; T1w-TSE = T1-weighted turbo spin echo; T2w-TSE = T2-weighted turbo spin echo; TI = inversion time; other abbreviation as in Table 1.

  • Per-patient analyses.

  • Hyperintensity/isointensity with short TI and hypointensity with long TI compared with the normal myocardium.

  • Quantified on a post-contrast TI scout sequence in 15 thrombi and 15 tumors (3 benign and 12 malignant).
