Simultaneous Multislice–Based 5‐Minute Lumbar Spine MRI Protocol: Initial Experience in a Clinical Setting

Abstract

A 5-minute SMS-based MRI protocol for lumbar spine imaging is feasible and can be achieved without significant impact in the overall diagnostic quality.

Advanced deep learning-based image reconstruction in lumbar spine MRI at 0.55 T – Effects on image quality and acquisition time in comparison to conventional deep learning-based reconstruction

“…The resulting acquisition times of 01:23–02:39 min per sequence and 07:59 min for the entire imaging protocol render 0.55 T low-field MRI of the lumbar spine competitive to current imaging protocols at higher field strengths. Fore reference, Sartorreti et al reported a total scan time of 11:28 min when using parallel imaging at 1.5 T in 2019 [25] and Longo et al achieved a protocol time of 5:28 min by the help of simultaneous multislice imaging at 3 T in 2022 [26] . The reduction in acquisition time trough deep learning reconstruction in our is comparable to other recently published investigations, e.g.…”

Diagnostic evaluation of deep learning accelerated lumbar spine MRI

“…18 Accelerated MRI techniques such as parallel imaging and compressed sensing have been developed and applied in recent years, leading to a marked reduction in acquisition times. [19][20][21][22][23] DL techniques have gained significant attention and importance in various fields, especially neuroimaging. 24 As a subfield of artificial intelligence (AI), DL has revolutionized the way clinical imaging is performed, offering innovative solutions for disease diagnosis, detection, and tumor segmentation.…”

Validation and Feasibility of Ultrafast Cervical Spine MRI Using a Deep Learning-Assisted 3D Iterative Image Enhancement System

“…In the past three decades, various acceleration techniques have been introduced in MRI. [4][5][6][7] Parallel imaging harnesses multiple receiver coils to simultaneously collect the MRI data. 8 Partial Fourier capitalizes on inherent data redundancy due to Hermitian symmetry, collecting only a fraction of the k-space.…”

“… 10 Nowadays, by integrating these acceleration techniques, routine spine MRI has already trimmed its total acquisition time to approximately 5 minutes without compromising diagnostic performance. 5 However, the footsteps towards faster skeletal imaging should not be ended. Despite the achievement, spine MRI still holds much longer acquisition time compared to CT.…”
