28 июл. 2020 г. · The MRI myocardial viability protocol encompasses a set of different MRI sequences for the assessment of myocardial viability.

In accordance with the clinical definition, viability is deemed as present when below 50% of the area of the affected segment, and absent when greater than 50%.
