There is extensive ongoing research in the field of Virtual colonoscopy/ CT colonography.  Therefore, each month there are numerous relevant publications.  It is difficult to keep up with all the developments.  In this section, each month I will highlight a selection of abstracts from scientific articles which I have found to be interesting. I encourage you to try to read the original article in its entirety, if you have the time.
