What is Image Quality of Lumbar Spine Imaging at 0.55T Low-Field MRI is Comparable to Conventional 1.5T MRI – Initial Observations in Healthy Volunteers about?

Rationale and Objectives: T a g g e d P To assess the potential of 0.55T low-field MRI system in lumbar spine imaging with and without the use of additional advanced postprocessing techniques.T a g g e d E n d Materials and Methods: T a g g e d P The lumbar spine of 14 volunteers (32.9 § 3.6 years) was imaged both at 0.55T and 1.5T using sequences from clinical routine. On the 0.55T scanner system, additional sequences with simultaneous multi-slice acquisition and artificial intelligencebased postprocessing techniques were acquired. Image quality of all 28 examinations was assessed by three musculoskeletal radiologists with respect to signal/contrast, resolution, and assessability of the spinal canal and neuroforamina using a 5-point Likert scale (1 = nondiagnostic to 5 = perfect quality). Interrater agreement was evaluated with the Intraclass Correlation Coefficient and the Mann-Whitney U test (significance level: p < 0.05).T a g g e d E n d Results: T a g g e d P Image quality at 0.55T was rated lower on the 5-point Likert scale compared to 1.5T regarding signal/contrast (mean: 4.16 § 0.29 vs. 4.54 § 0.29; p < 0.001), resolution (4.07 § 0.31 vs. 4.49 § 0.30; p < 0.001), assessabi
