Cure8 research brief
Reducing radiation and iodine exposure matters for people with Crohn’s disease who often need repeated imaging. Safer CT enterography protocols that maintain image quality could lower cumulative risks and contrast load.
Patients with Crohn’s disease who require CTE, radiologists and imaging teams, gastroenterologists managing imaging follow-up, and clinicians concerned about cumulative radiation/contrast exposure.
This was a single-center, prospective randomized trial of 102 Crohn’s disease patients comparing a standard CTE protocol, a low-dose protocol (100 kVp + ASIR-V), and a low-dose plus reduced-iodine protocol. The primary endpoint was subjective image quality; no significant differences were seen between groups.
Radiation dose was about halved in the low-dose groups; the combined low-dose/low-contrast arm achieved the predefined iodine reduction. Diagnostic accuracy for disease activity and stenosis was reported as exploratory but the study was not powered to demonstrate non-inferiority, so the diagnostic comparisons are inconclusive.
Practical takeaways: If radiation reduction is the priority, the study authors recommend the low-dose protocol; if both radiation and iodine reduction are desired, the combined protocol may be considered. These recommendations are protocol- and vendor-specific (GE Revolution 256-row CT) and should be applied in consultation with local radiology teams.
This is a single-center study on a specific CT platform and was not powered to prove diagnostic non-inferiority; reported diagnostic comparisons are exploratory. Local equipment, reconstruction software, and radiology expertise affect whether similar dose reductions and image quality can be achieved. Summary grounded in the article abstract.

People with Crohn’s disease who have an ileostomy have limited noninvasive ways to monitor small-bowel inflammation. This study suggests measuring fecal calprotectin from ileostomy output could help detect postoperative...
Transmural healing on CT enterography was associated with fewer hospitalizations over long follow-up, which could matter for long-term disease management and monitoring strategies in Crohn’s disease.
A noninvasive, explainable model that combines CT enterography radiomics with CRP could make it easier to monitor mucosal healing in small‑bowel Crohn’s disease without repeated invasive enteroscopy, especially after...
