Subtracted synthetic images in Gd-DTPA enhanced MR.
The evaluation of Gd-DTPA contrast enhancement (CE) in high intensity tissues on T1-weighted magnetic resonance images, such as fat and bone marrow, is quite difficult. In this study, we used subtraction and subtracted color images in an attempt to show more clearly the Gd-DTPA CE. In addition, we also carried out sequential post-Gd-DTPA imaging to assess the changes in enhancement of lesions with time. Twenty patients were studied with these methods and our results are illustrated.
