ABSTRACT

OBJECTIVE:

There are concerns that not all costly advanced imaging is appropriate. However, studies about the appropriateness of magnetic resonance imaging (MRI) are sparse. The aim of this study was to review various MRI examinations done at a university hospital to determine whether there is inappropriate use.

METHODS:

Altogether 150 common MRIs (upper abdomen or liver, lumbar spine, knee, head and head of children performed under anaesthesia, 30 each) were reviewed consecutively. The referrals and corresponding patient files were analysed by senior radiologists and the indications of the examinations were compared to the referral criteria.

RESULTS:

Seven per cent of the examinations were deemed inappropriate. All the MRIs of the head done on children were indicated. One to three examinations in all other subgroups were not indicated. The most common appropriate indications were ambiguous hepatic, pancreatic or adrenal lesions, prolonged lower back pain, suspicion of meniscus rupture, brain malignancy and developmental disorder of a child, respectively.

CONCLUSIONS:

Although the proportion of inappropriate examinations was not high; financial issues and the growing number of patients referred for MRI are of concern. Education and regular use of up-to-date referral guidelines could help to further improve appropriateness. MAIN MESSAGES •Seven per cent of the MRI examinations analysed were inappropriate at a university hospital. •Everyday practices of a hospital may contribute to the level of appropriateness. •A survey of indications for previous MRI examinations might be helpful in various institutions.
