“…The authors described limited accuracy for low grade (I and II) cartilage defects, which is in agreement with our study. Other researchers using previous generation machines similarly found good diagnostic performance of low-field MRI systems when compared with arthroscopy, also highlighting the limitations for cartilage and meniscus evaluation 19–21 . Overall, 12/14 (86%) cartilage lesions and 15/17 (88%) meniscus lesions identified on 3 T MRI were also identified and equally graded on 0.55 T MRI.…”

“…Other researchers using previous generation machines similarly found good diagnostic performance of low-field MRI systems when compared with arthroscopy, also highlighting the limitations for cartilage and meniscus evaluation. [19][20][21] Overall, 12/14 (86%) cartilage lesions and 15/17 (88%) meniscus lesions identified on 3 T MRI were also identified and equally graded on 0.55 T MRI. One may hypothesize that a similar difference could be found when comparing 3 T with 1.5 T knee MRI, especially when considering low-grade lesions.…”

Objectives The aim of this study was to compare the detection rate of and reader confidence in 0.55 T knee magnetic resonance imaging (MRI) findings with 3 T knee MRI in patients with acute trauma and knee pain. Materials and Methods In this prospective study, 0.55 T and 3 T knee MRI of 25 symptomatic patients (11 women; median age, 38 years) with suspected internal derangement of the knee was obtained in 1 setting. On the 0.55 T system, a commercially available deep learning image reconstruction algorithm was used (Deep Resolve Gain and Deep Resolve Sharp; Siemens Healthineers), which was not available on the 3 T system. Two board-certified radiologists reviewed all images independently and graded image quality parameters, noted MRI findings and their respective reporting confidence level for the presence or absence, as well as graded the bone, cartilage, meniscus, ligament, and tendon lesions. Image quality and reader confidence levels were compared (P < 0.05 = significant), and clinical findings were correlated between 0.55 T and 3 T MRI by calculation of the intraclass correlation coefficient (ICC). Results Image quality was rated higher at 3 T compared with 0.55 T studies (each P ≤ 0.017). Agreement between 0.55 T and 3 T MRI for the detection and grading of bone marrow edema and fractures, ligament and tendon lesions, high-grade meniscus and cartilage lesions, Baker cysts, and joint effusions was perfect for both readers. Overall identification and grading of cartilage and meniscal lesions showed good agreement between high- and low-field MRI (each ICC > 0.76), with lower agreement for low-grade cartilage (ICC = 0.77) and meniscus lesions (ICC = 0.49). There was no difference in readers' confidence levels for reporting lesions of bone, ligaments, tendons, Baker cysts, and joint effusions between 0.55 T and 3 T (each P > 0.157). Reader reporting confidence was higher for cartilage and meniscal lesions at 3 T (each P < 0.041). Conclusions New-generation 0.55 T knee MRI, with deep learning–aided image reconstruction, allows for reliable detection and grading of joint lesions in symptomatic patients, but it showed limited accuracy and reader confidence for low-grade cartilage and meniscal lesions in comparison with 3 T MRI.

Since it was first introduced in the field of medical imaging in the early 1980s, MRI has become essential for the diagnosis and treatment of musculoskeletal conditions. Most imaging in the United States is performed on high-field (Ͼ1.0T), whole-body scanners. However, for reasons discussed below, imaging at low (Ͻ0.5T) and medium (0.5-1.0T) field strengths using small, low-cost, easily installed scanners in imaging centers and physicians' offices is gaining increasing popularity. Such scanners can be very useful for imaging the upper and lower extremities, from the shoulder to the fingers and the hips to the toes. In this review we provide an overview of the different available extremity scanners and their advantages and disadvantages, briefly review the literature regarding their use, and discuss our experience in using low-field extremity scanners to evaluate joints.
