MRI^¶
Major
Ratio of RV end-diastolic volume to BSA
Males	≥110 mL/m²	76	90
Females	≥100 mL/m²	68	98
or RV ejection fraction	≤40 percent
Minor
Ratio of RV end-diastolic volume to BSA
Males	≥100 mL/m²	79	85
Females	≥90 mL/m²	89	97
or RV ejection fraction	≤45 percent

PLAX: parasternal long-axis view; RVOT: right ventricular outflow tract; BSA: body surface area; PSAX: parasternal short-axis view.
* All the major and minor criteria listed in this table are in addition to the requirement that regional wall motion abnormalities must also be present.
¶ The sensitivity and specificity for males and females are the same as listed if, in addition to the stated wall motion criteria, there is either abnormal RV size or function or both.
