为了在静脉注射单剂量钆双胺后在单个图像上单独显示内淋巴、外淋巴和骨，我们将灰度倒置阳性内淋巴（PEI）与天然阳性外淋巴（PPI）图像融合，即，我们从PPI中减去PEI。减影显著改善了内淋巴和外淋巴之间的对比噪声比和内淋巴间隙的主观可见性评分。纳入了24名疑似梅尼埃病的患者。
For the separate visualization of endolymph, perilymph, and bone on a single image after intravenous injection of single-dose gadodiamide, we fused gray-scale inverted positive endolymph (PEI) with native positive perilymph (PPI) images, that is, we subtracted PEI from PPI. Subtraction significantly improved the contrast noise ratio between endolymph and perilymph and the subjective visibility score for endolymphatic space. The 24 patients with the suspect of Meniere's disease were included.
