The additive European MRI scoring system

Type of change	Score
Subchondral cysts Present in at least one bone Present in at least two bones More than three cysts in at least one bone More than three cysts in at least two bones Largest size > 4 mm in at least one bone Largest size > 4 mm in at least two bones	1 1 1 1 1 1
Enlargement of epiphysis	Absent = 0 Present = 1
Irregularity of subchondral surface	Absent = 0 Partially involved = 1 Totally involved = 2
Narrowing of joint space	Absent = 0 Joint space > 1 mm = 1 Joint space < 1 mm = 2
Subchondral cysts formation	Absent = 0 1 cyst = 1 >1 cyst = 2
Erosion of joint margins	Absent = 0 Present = 1
Gross incongruence of articulating bone ends	Absent = 0 Slight = 1 Pronounced = 2
Joint deformity (angulation and/or displacement)	Absent = 0 Slight = 1 Pronounced = 2
