Title: Measuring distance from the incisors to the esophageal cancer by FDG PET/CT:
Endoscopy as the reference
Version: 1 Date: 22 Nov 2021
Reviewer's report:
The authors, using endoscopy as the reference, evaluated the accuracy of FDG PET/CT in
measuring distance from the incisors to the PET detectable esophageal cancer.
This well-written article may have some point of comment.
1. The difference of patients' posture between two examinations exists. This is a fundamental
problem.
2. The authors need to support their measurement method and proof with some pictures for
example and full pictures as supplements.
3. In deviated esophagus or tortuous esophagus, the accuracy of measurement would be
compromised.
4. The mean "absolute" difference between two measurements around 1cm would be important
clinically. If the difference is positive or negative in all cases, the clinical importance would be
less important.
