据报道，通过静脉注射单剂量钆双胺后从阳性外淋巴图像中减去阳性内淋巴图像创建的HYDROPS（阳性内淋巴信号的反转图像和阳性外淋巴信号的天然图像的混合）图像有助于识别内淋巴积水。为了进一步提高HYDROPS图像的对比噪声比（CNR），我们将T-2加权MR脑池造影图像乘以HYDROPS图像。10例疑似梅尼埃病患者被纳入。生成图像的平均CNR增加到HYDROP图像的200倍以上。
A HYDROPS (HYbriD of Reversed image Of Positive endolymph signal and native image of positive perilymph Signal) image, created by subtracting a positive endolymph image from a positive perilymph image after intravenous injection of single-dose gadodiamide, has been reported to facilitate recognition of endolymphatic hydrops. To further increase the contrast-to-noise ratio (CNR) of HYDROPS images, we multiplied a T-2-weighted MR cisternographic image onto the HYDROPS image. Ten patients with suspected Meniere's disease were included. The average CNR of generated images increased to more than 200 times that of HYDROP images.
