The identification of the culprit lesion in apical parodontitis is often difficult due to the only limited performance of X-ray based techniques in delineation of acute and chronic inflammation. We applied MRI in 11 pain patients and compared the outcome with cone beam CT images. T2-weighted MRI appears to be a promising tool for the identification of the acute inflamed lesion and clearly outperforms X-ray based techniques.
