Utilizing 3D fast spin echo anatomical imaging to reduce the number of contrast preparations in T1ρ$$ {T}_{1\rho } $$ quantification of knee cartilage using learning‐based methods
The proposed approach enables efficient <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML"> <mml:semantics> <mml:mrow> <mml:msub><mml:mrow><mml:mi>T</mml:mi></mml:mrow> <mml:mrow><mml:mn>1</mml:mn> <mml:mi>ρ</mml:mi></mml:mrow> </mml:msub> </mml:mrow> <mml:annotation>$$ {T}_{1\rho } $$</mml:annotation></mml:semantics> </mml:math> mapping using PD-weighted anatomical images, reducing scan time while maintaining clinical standards. This method has the potential to facilitate the integration of quantitative MRI techniques into routine clinical practice, benefiting OA diagnosis and monitoring.
