Abstract

Anatomical dedicated low-field-strength MR imaging (non-whole-body-systems) has been developed for examinations of the peripheral joints. It has several advantages compared to high-field-strength MR imaging (whole-body-systems). The dimensions are small, the noise is not as bad as in whole body systems and people do not suffer of claustrophobic attacks. However, our results of a prospective blinded study in 56 patients with three different kinds of peripheral joint injuries demonstrated that the 0.2 T dedicated system showed a significant lower rate of diagnostic accuracy compared to middle and high-field-strength MR imaging and scored with obvious lower image quality ratings.
