Comprehensive study of routine clinical use of cardiac MRI in a district general hospital setting

The study sought to evaluate the indications, image quality, safety and impact on patient management of cardiac magnetic resonance imaging (CMR) in a district general hospital setting.  The database was developed using retrospective analysis of patient records from the start of the local CMR service in January 2014 until January 2017. All 791 consecutive patients were included in the dataset.

The most important indications were the investigation of myocarditis/cardiomyopathies (54.5%), work-up of suspected coronary artery disease (CAD)/ischaemia (27.1%), and assessment of viability (9.1%). Image quality was diagnostic in 99.9% of cases. Mild adverse effects were reported for 3.8% of patients for stress CMR and in 1.1% of non-stress CMR. No serious adverse events were reported in this study population. In 26.5% of cases, CMR findings resulted in therapeutic modifications. In 18.1%, the final diagnosis based on CMR was different to that suspected before the CMR.

In conclusion, the findings of this study emphasise that CMR is a safe procedure with high image quality. In many cases, CMR can be shown to change a patient’s management plan.
