Cure8 research brief
Noninvasive intestinal ultrasound with superb microvascular imaging (SMI) may help predict the presence and size of endoscopic ulcers in the terminal ileum of people with Crohn’s disease. That could improve noninvasive monitoring and help guide decisions about when to perform colonoscopy.
Clinicians who perform or interpret intestinal ultrasound, gastroenterologists managing Crohn’s disease, researchers studying imaging biomarkers, and patients interested in noninvasive monitoring options.
This retrospective study (204 Crohn’s disease patients) compared superb microvascular imaging (SMI) grades from intestinal ultrasound with ileocolonoscopy findings in the terminal ileum. Higher SMI and modified Limberg (mLS-SMI) grades were associated with greater prevalence of endoscopic ulcers.
SMI grade ≥1 had higher sensitivity but lower specificity than mLS-SMI ≥2 for predicting small or large ulcers. SMI is an ultrasound technique that detects low-velocity microvascular flow and here was graded 0–3 (SMI) and 0–4 (mLS-SMI).
The study reports sensitivity and specificity values for different grade thresholds; for example, SMI ≥1 predicted small/large ulcers with 70% sensitivity and 88% specificity. The authors conclude SMI grading may add information when evaluating ulcerative lesions in the terminal ileum.
If you’re a patient, note this is an imaging/diagnostic study (retrospective) and does not test a treatment. The findings suggest intestinal ultrasound with SMI could help flag ulcerative disease that may warrant endoscopic confirmation, but it does not replace colonoscopy.
This is a retrospective single-study report using a specific ultrasound platform and grading systems; sensitivity and specificity vary by chosen thresholds. Results may need prospective validation across centers and devices before changing practice.

Early intestinal ultrasound may predict one-year endoscopic remission in Crohn's disease, offering a noninvasive tool to guide treatment decisions and possibly reduce the need for some colonoscopies.
This study suggests intestinal ultrasound findings early after diagnosis — especially achieving “transmural remission” within 3 months — may predict better 1-year outcomes (sustained steroid-free remission and less need...
If intestinal ultrasound shows mild isolated hyperemia even with normal bowel wall thickness, this study found a higher chance of treatment changes, steroid use, surgery, or hospitalization within a year — information...
