It will also learn about the safety of 3-dimensional (3D) imaging device. The main questions it aims to answer are:\n\nDoes 3-dimensional (3D) imaging device improve the identification of patients with high risk adenomas? What adverse events do participants experience during colonoscopy? Researchers will compare 3-dimensional (3D) imaging device to traditional 2-dimensional (2D) imaging device to see if 3-dimensional (3D) imaging device works to improve high risk adenoma identification.\n\nParticipants will:\n\nUndertake colonoscopy examination using 3-dimensional (3D) imaging device or 2-dimensional (2D) imaging device.
