Key result
Omitting outer-volume suppression in single-slice spiral perfusion imaging improves image quality scores by 1 point.
Why the study?
To develop a high spatial resolution spiral first-pass myocardial perfusion imaging technique with whole-heart coverage at 3T to assess transmural perfusion differences, quantify ischemic burden, and improve detection of obstructive coronary artery disease.
Does whole-heart high-resolution spiral perfusion imaging at 3T provide high-quality images for assessing myocardial perfusion?
Does whole-heart high-resolution spiral perfusion imaging at 3T provide high-quality images for assessing myocardial perfusion?
Absolute Event Rate: 4.5% vs 3.5%
p-value: p=< .05
Whole-heart spiral perfusion imaging with high resolution at 3T is feasible and provides good image quality, particularly using single-slice acquisition without outer-volume suppression.
Whole-heart high-resolution spiral perfusion imaging at 3T is feasible with good quality; leaves open diagnostic performance versus standard methods.

Wang et al. (2021) studied Healthy volunteers and patients evaluated for coronary artery disease (n=42). Whole-heart high-resolution spiral perfusion imaging (single-slice without outer-volume suppression) vs. Single-slice with outer-volume suppression and simultaneous multi-slice acquisitions was evaluated on Image quality graded on a 5-point scale (5=excellent, 1=poor) (p=< .05). Whole-heart high-resolution spiral perfusion imaging at 3T achieved good image quality, with single-slice acquisition without outer-volume suppression scoring highest (4.5 vs 3.5 with OVS; P<0.05).
