CTC is a safe and accurate cancer detection technique widely used overseas but underused here

Computed tomography colonography (CTC), also known as virtual colonoscopy, is a minimally invasive method for examining the whole colon using computed tomography to acquire images after distension of the colon with air or carbon dioxide through a small rectal tube. Dedicated software enables 2D and 3D fly-through models for interpretation. No sedation is required. CTC has been used since the mid-1990s, the earliest Australian experience being in 1996–1997.1
