The diagnosis of apical periodontitis and the differentiation between acute and chronic lesions with MRI requires images of identical anatomy with different contrasts (T1w and T2w). A reduction of examination time can be obtained by sharing the information of high frequency components of k-space. Using the information of an high resolution reference scan (T1w) a high resolution multi contrast image of a low-resolution T2w scan of the same anatomy can be provided.
