The lightbox was very bright, Takahashi had looked for a long time but could not see the necrotic bone mentioned by Yang Ping.
Yang Ping had already indicated the area with a slight abnormality, but in Takahashi's understanding, that was an impression made by a blood vessel, a typical vascular imprint. How could it be seen as necrotic bone? Necrotic bone and vascular impressions are two completely unrelated concepts and now they have become connected in the differential diagnosis.
Staring into the bright light for too long, Takahashi's vision began to blur, his eyes began to sting, tears were squeezed out, and he had to divert his gaze temporarily. He looked away, his vision filled with flashes of light, even people were flickering in his sight.
