Introducing hyperspectral imaging as a novel tool for assessing donor liver quality during machine perfusion: A case report

Figure 1 Hyperspectral image before discarding the liver - segments II and III. Macroscopically, patchy alterations are observed. Hyperspectral imaging reveals decreased oxygenation on the liver surface, primarily reflected in shades of green, indicating approximately 40%-50% oxygen saturation. Moreover, near-infrared perfusion detects critically low oxygen saturation levels, ranging from 0%-20%, at a depth of 4-6 mm in those areas.

Figure 2 Histological analysis of discarded liver. Histology shows areas of sinusoidal dilatation and congestion with atrophy and hypoxic injury of hepatocytes (left), and normal liver for comparison (right, original × 100).
