To develop a single-shot spiral perfusion pulse sequence with outer-volume suppression (OVS) to achieve whole heart coverage with a short temporal footprint of 10 ms per slice location. A highly-accelerated single-shot variable density spiral pulse sequence with an integrated OVS module for reduced FOV (rFOV) perfusion imaging with 2 mm spatial resolution was developed and evaluated in simulations, phantom experiments and in clinical patients with (N=8) or without OVS (N=8). Images were reconstructed by block low-rank sparsity with motion-guidance (BLOSM) and graded by two cardiologists on a 5-point scale (1-excellent, 5-poor). Simulation and phantom results showed that OVS effectively suppressed the signal outside the desired FOV. Clinical patient data demonstrated high quality perfusion images with rFOV. The average image quality scores of full FOV cases and rFOV cases were 3.1 ± 0.64 and 2.3 ± 0.46 (p = 0.02) from cardiologist 1, and 2.5 ± 0.54 and 1.8 ± 0.47 (p = 0.04) from cardiologist 2, showing superior image quality for the rFOV images as compared to the full FOV images. A single-shot spiral perfusion sequence which utilizes OVS and BLOSM performs perfusion imaging with a very short temporal footprint per image supporting whole-heart coverage with good image quality.
