Grade 3: filling delay or CVH area is entirely involved in the dilated vortex vein region.

Grade 2: 50% or more of filling delay or CVH area overlaps with the dilated vortex vein region.

Grade 1: less than 50% of filling delay or CVH area overlaps with the dilated vortex vein region.

Grade 0: no tendency for overlapping between filling delay or CVH area and dilated vortex vein region.
