Cardiac MRI Viability Transmurality Assessment

Assess myocardial viability from LGE transmurality. <25% transmural LGE: high viability; 26-50% intermediate; >50% non-viable.

Clinical Guidance

BMI is a screening measure of body size, not a direct measure of body fat. The standard WHO categories are underweight (<18.5), normal (18.5–24.9), overweight (25–29.9), and obese (≥30).

BMI can overestimate body fat in athletes with high muscle mass and underestimate it in older adults with low muscle mass. Interpret it alongside waist circumference and clinical context rather than as a standalone diagnosis.

How It Works

Assess myocardial viability from LGE transmurality. <25% transmural LGE: high viability; 26-50% intermediate; >50% non-viable

Each component has a specific meaning:

  • LGE transmurality — The lge transmurality recorded for the scenario being assessed.

Note: Interpret the cmr viability result against the thresholds and context described above.

How to Use

Enter the LGE transmurality for the scenario you are assessing. Assess myocardial viability from LGE transmurality. <25% transmural LGE: high viability; 26-50% intermediate; >50% non-viable. Use the cmr viability result to inform your calculation.
