[Application of T1-weighted images by contrast-enhanced frequency-selective presaturation in magnetic resonance
1Department of Radiology, Xiangya Hospital, Hunan Medical University, Changsha.
Abstract:
In this study contrast-enhanced frequency-selective presaturation T1-weighted images and contrast-enhanced spin echo T1-weighted images in 32 cases were detected and analysed comparatively regarding enhancing lesions and the signal intensity of enhancing lesions. The results showed that in the signal intensity of enhancing lesion, the contrast enhanced frequency-selective presaturation T1-weighted images showing high sign were greater than contrast-enhanced spin echo T1-weighted images. The former was better than the later in accurate evaluation of the margin, size and the differential diagnosis of enhancing lesion, especially in the regions containing more fat and bone marrow.
