Highly efficient image navigator based 3D whole‐heart cardiac MRA at 0.55T
The proposed approach enables 3D whole-heart CMRA at 0.55T in a 6-min scan ( <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML"> <mml:semantics><mml:mrow><mml:mn>5</mml:mn> <mml:mo>.</mml:mo> <mml:mn>9</mml:mn> <mml:mo>±</mml:mo> <mml:mn>0</mml:mn> <mml:mo>.</mml:mo> <mml:mn>7</mml:mn> <mml:mo> </mml:mo> <mml:mi>min</mml:mi></mml:mrow> <mml:annotation>$$ 5.9\pm 0.7\;\min $$</mml:annotation></mml:semantics> </mml:math> ), providing excellent image quality, minimal artifacts, and comparable vessel sharpness to previous 1.5T studies. Future work will include the evaluation of the proposed approach in patients with cardiovascular disease.
