Parameters used for the characterization of LNs and associated scoring system. For volume, wash-in rate, and time-to-peak, data from left LNs were compared to data from control right LNs.

Score	Volume Ratio	Shape	Hilum	Wash-in Rate	Time-to-Peak
Score: 1	Left LN at least 5× larger than control (right) LN	Length–width ratio < 2 (round)	Not detected	Significantly reduced in left LN compared to control (right) LN	Significantly increased in left LN compared to control (right) LN
Score: 0	Left LN smaller or equal to control (right) LN	Length–width ratio > 2 (non-round)	Detected	Lengthened in left LN or equal to control (right) LN	Reduced in left LN or equal to control (right) LN
