	Patient 1	Patient 2	Patient 3	Patient 4	Patient 5
Elastography pattern	Score 3	Score 3	Score 5	Score 5	Not performed
Contrast enhanced harmonic EUS	Slightly decreased enhancement at 1 min, followed by a continuously increasing enhancement at 3 to 5 min	Uniformly increasing enhancement	Strong continuous enhancement	Early enhancement within 1 min, followed by washout to hypovascular	Early enhancement, followed by gradual decrease after 1 min
