Radiographic capsule-based system for non-cathartic colorectal cancer screening

摘要

Many patients are reluctant to undergo optical colonoscopy for colorectal cancer screening. The Check-Cap colon imaging system is a non-invasive test that comprises an ingestible imaging capsule that emits and detects ultra-low-dose radiation. The capsule generates a 3D reconstruction of the colonic lumen for detection of polyps and cancer. Preliminary preclinical and clinical testing has demonstrated safety and feasibility. Mean radiation dose is estimated at 0.04 mSv. In conclusion, we describe a novel capsule-based, patient-friendly colorectal test that holds potential for non-invasive screening.
