# Rectification of Priority: Giuseppe Vicentini (1860–1944) Presented the First Luminal Contrast Enhanced X‑Ray of the Digestive Tract on January 26, 1896

## TL;DR

Giuseppe Vicentini took the first X-ray of a contrast-enhanced digestive tract in 1896, correcting historical credit.

## Contribution

Corrects historical attribution by identifying Vicentini as the first to perform luminal contrast X-rays of the digestive tract.

## Key findings

- Giuseppe Vicentini presented the first X-ray of an opacified gastrointestinal tract in 1896.
- The X-ray was taken using an animal model during a pioneering study period.

## Abstract

Giuseppe Carlo Antonio Vicentini (1860–1944), professor of experimental physics at the University of Padova, Italy, presented on January 26, 1896, the X‑rays he made during a brief pioneering study period. Among those was the first roentgenograph of an opacified gastro‑intestinal tract, obtained of an animal model.
