Colonoscopy, also known as virtual colonoscopy. This is an imaging technique that does not require an endoscope. This technique is much superior to other traditional diagnostic methods, so it is widely applied in modern medicine.

Colon cancer is one of the most common cancers in Vietnam. However, only about 20% of patients are detected when the disease is in the final stage and has metastasized. Meanwhile, colon cancer is a disease that can be cured when detected at an early stage. Therefore, screening for colon cancer through multi-slice CT scans will help patients have a better chance of survival.

Computed tomography colonography, also known as virtual colonoscopy (VC), was introduced in 1994 by Vining et al. They were the first to describe this modified computed tomography (CT) scan of the large intestine as a diagnostic test for colorectal carcinoma and polyps. Since then, virtual colonoscopy has become an essential test in the imaging of polyps and occult colorectal cancer in patients who are not candidates for optical colonoscopy.

Computed tomography colonography - virtual colonoscopy (C-scan CT) has become an important screening method in the detection of colon polyps and colorectal carcinoma (CRC). The main advantages of virtual colonoscopy are its non-invasive nature and high pathological assessment ability.
