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 Ménière's disease were included.
为了在单次静脉注射钆喷酸葡胺后在单个图像上分别显示内淋巴、外淋巴和骨，我们将灰度反转的正内淋巴（PEI）与原始的正外淋巴（PPI）图像融合，即从 PPI 中减去 PEI。减影显著提高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视评分。本研究纳入了 24 例疑似梅尼埃病的患者。
