Virtual biopsy probe system is 'almost perfect' in detecting precancerous polyps during colonoscopy
- ScienceDaily
- 10/3/23 05:00
The newest generation of "virtual biopsy" colonoscopy probes being tested demonstrate that it might soon be possible to use such a device to determine whether a colon polyp is benign and not remove it for biopsy. Currently, all colon polyps are extracted during a colonoscopy and sent to a pathologist for examination, which adds time, expense, and some surgical risk, to the...
