Table 4. CoV of individual data of RT data acquisition* and FB data acquisition**.

CoV	Dslow (×10-3 mm2/s)	PF (%)	Dfast (×10-3 mm2/s)
CoV of RT data (n=17)	17.06%	40.41%	51.04%
CoV of FB data (n=6)	8.72%	16.90%	24.00%

*, RT data acquisitions data from references (9-11,15,23,24,42,43,45,46,48,51,53-55); **, FB data acquisitions from references (19-21,40,41,47). CoV, coefficient of variation; RT, respiratory triggering; PF, perfusion fraction; FB, free-breathing.
