Motivation: Coronary artery examination in elderly patients with low renal function and poor respiratory coordination has always been a clinical pain point.
Goal(s): Explore the feasibility of balanced steady-state free precession BTFE sequence for non-drug coronary imaging and find the optimal compressed sensing coefficient under this sequence
Approach: Acquire cs4, 6, and 8 images under BTFE sequence, record acquisition time and analyze objective indicators and subjective scores
Results: CS6 can achieve relatively high imaging quality in a short time
Impact: Our study may inform efforts to more rapidly perform non-contrast enhanced coronary MRI angiography in elderly patients.
