Analysis of image success rate, image quality and influencing factors of 3.0T whole-heart non-contrast MR coronary angiography in 1053 cases

Key Points

Improvements in image quality and success rates can significantly enhance diagnostic outcomes.
This study identifies body mass index and heart rate as independent influential factors in imaging.
Utilization of compressed sensing technology contributes to reduced scanning time and enhanced image quality.
The approach is especially beneficial for elderly and respiratory unstable patients needing coronary assessments.

Abstract

Motivation: Coronary artery disease (CAD) is the leading cause of cardiovascular disease worldwide, causing more than 62% of heart failure. Non-enhanced CMRA does not require contrast agents and radiation, but the imaging time is long, and the success rate and image quality are limited. Goal(s): To shorten the imaging time, reduce motion artifacts, and improve tolerance and diagnostic accuracy through sparse sampling and optimized reconstruction. Approach: This study uses a 3D balanced steady-state free procession sequence (BTFE) with compressed sensing (CS) technology. Results: Findings reveal patient's body mass index (BMI) and heart rate are independent influencing factors. Impact: Our study to improve image quality can shorten scanning time, increase success rate, and significantly improve image quality. It is especially suitable for examination of elderly and respiratory unstable patients.
