|Comparative study to estimate diagnostic efficacy of 0,3 T MRI for evaluation of knee injuries, using arthroscopy as a reference standard|
Aims and objectives
Our aim was to evaluate the evidence for the diagnostic efficacy of 0,3-T MRI for knee injuries using arthroscopy as the reference standard.
Over the years, with the evolution of machines and study protocols, MR has been confirmed as a non-invasive and highly sensitive instrument in the evaluation of osteo-ligamentous structures, articular surfaces and peri-articular knee tissue.
Arthroscopy, on the opposite side, confirms a highly sensitive and specific procedure for evaluating endocapsular structures, but invasive and sometimes not well accepted as diagnostic mode.
High-intensity field devices (> 1T) allow for spatial and contrast resolution and a signal-to-noise ratio (SNR) not obtainable on low-field equipment (<0.5T), if not increasing scanning time at the expense of increasing artifacts from movement.
In this study, we emphasized the use of low-field equipment dedicated to the joints, cheaper and more versatile than the large and expensive high-field equipment of proven diagnostic quality.
