[Clinical trial of color-hybrid images for assessment of Gd-DTPA contrast enhancement].
Gd-DTPA (Gd) has been shown to provide effective contrast enhancement in MR imaging. However, it is sometimes impossible to evaluate Gd contrast enhancement (C.E.) in high intensity tissues like fat and bone marrow. To solve this problem, color-hybrid images (hybrid images) were generated by the use of an RGB mixing method. A total of 54 lesions, including 30 bone and soft tissue lesions and 24 gynecological lesions, were studied. In most cases, the hybrid images were superior to the original ones in terms of both morphologic and temporal evaluation of Gd C.E. The hybrid images helped to define the localization and extent C.E., by providing better visualization through the use of color display.
