In comparison to high field MR-scanners, the main
disadvantages of low field MR-scanners are reduced
signal-to-noise Ratio (SNR) and resolution in comparison
with higher magnetic field strength. Despite these
limitations, several publications which compared low
field MRI to arthroscopy showed good sensitivity and
specificity for the detection of cruciate ligament
ruptures and meniscus lesions. Since there are no
publications using low field MR-scanners of the newest
generation so far, the objective of this study was to
analyze the capabilities of low field MR-scanner of the
newest generation in the detection of musculoskeletal
knee injuries of acute trauma patients in comparison to
the gold standard (arthroscopy and CT). In our study we
observed very good sensitivity and specificity in the
diagnosis of traumatic meniscal tears, ACL tears as well
as fractures with low field MRI. Advantages of low field
MRI are the reduced costs for purchasing and
maintenance. It follows that high patient throughput
based on economic pressure is not necessary, allowing to
keep examination slots free for acute trauma patients.
