Read Chapter 33: — WHAT THE SCAN CANNOT SHOW

That winter, Daniel taught first-year students.

He displayed a PET image without giving the diagnosis.

"What do you see?" he asked.

Hands rose.

Metastatic disease. Inflammation. Physiological uptake. Technical artefact.

Daniel listened.

Then he changed the slide.

A photograph appeared: Margaret in her red lipstick and navy coat, glaring at the camera because Clara had taken the picture while she was eating.

The room became quiet.

"The scan was hers," Daniel said. "Never forget the grammar of that sentence. The image belongs to the patient before it belongs to you."

A student asked whether that made diagnosis harder.

"Yes," Daniel said.

"Isn't that bad?"

"No. It makes responsibility heavier. That's different."
