Atlas of Gastrointestinal Imaging, Chapter 5 -- The Colon and Rectum

Imaging evaluation of the large intestine has undergone remarkable advances over the past decade, particularly with the advent of CT colonography (CTC, also referred to as virtual colonoscopy). Optical colonoscopy (also referred to as conventional or invasive colonoscopy) and CTC allow for complementary diagnostic evaluation of the colonic mucosa.

Could AI scoring help with managing DCIS?

By Amerigo Allegretto

An AI model showed associations with recurrence after DCIS surgery and performed comparably to established clinical risk models.

February 11, 2026

Images of a 39-year-old who underwent screening mammography. Right craniocaudal (left) and mediolateral oblique (middle) views from preoperative mammography show suspicious grouped fine pleomorphic calcifications (arrows). After biopsy showed ductal carcinoma of situ (DCIS), patient underwent breast-conserving surgery, yielding final diagnosis of ductal carcinoma in situ (intermediate grade, hormone receptor positive). (Right) Screenshot of an output of a commercial AI tool applied to preoperative mammography. AI detected right breast lesion with score of 95% on both views (concentric colored circles). Present study’s reviewing radiologist deemed AI marking to correspond with site of DCIS.

Clinicians, beware: CT diagnostic accuracy varies by adnexal lesion type

By Kate Madden Yee

The modality correctly diagnoses dermoids and simple cysts, but is not as effective at identifying other types of adnexal lesions.

February 11, 2026

Axial contrast-enhanced CT scan in a 28-year-old premenopausal woman shows an incidentally detected solid-appearing left ovarian lesion (solid arrow) anterior to the uterus (U), associated with trace ascites in the right adnexa and cul de sac (dashed arrows). At pathologic analysis, this was shown to be ovarian dysgerminoma. Two readers misdiagnosed this lesion, one as a leiomyoma and one as an ovarian fibroma.
