Fast and accurate calculation of myocardial T₁ and T₂ values using deep learning Bloch equation simulations (DeepBLESS).

ABSTRACT:

Purpose

To propose and evaluate a deep learning model for rapid and accurate calculation of myocardial T₁ /T₂ values based on a previously proposed Bloch equation simulation with slice profile correction (BLESSPC) method.

Methods

Deep learning Bloch equation simulations (DeepBLESS) models are proposed for rapid and accurate T₁ estimation for the MOLLI T₁ mapping sequence with balanced SSFP readouts and T₁ /T₂ estimation for a radial simultaneous T₁ and T₂ mapping (radial T₁ -T₂ ) sequence. The DeepBLESS models were trained separately based on simulated radial T₁ -T₂ and MOLLI data, respectively. The DeepBLESS T₁ -T₂ estimat
