A light-based scan could detect deadly bowel disease in preterm babies

Necrotizing enterocolitis (NEC) kills premature infants with shocking speed, often before doctors can intervene. Researchers have developed a light-based imaging technique that detects the disease in its earliest stages, potentially saving lives in neonatal intensive care units.

NEC destroys the intestinal tissue of preterm babies, particularly those born before 32 weeks of gestation. The condition progresses rapidly, and current diagnostic methods rely on abdominal X-rays, which show damage only after significant tissue death has already occurred. By then, survival rates drop sharply.

The new approach uses diffuse optical imaging, a technology that shines near-infrared light through the infant's abdomen and measures how the tissue absorbs and scatters that light. Changes in tissue oxygen levels and blood flow patterns characteristic of NEC produce distinct optical signatures. The scan takes minutes and exposes babies to no ionizing radiation, unlike X-rays.

Researchers tested the imaging method on premature animals and found it could identify NEC hours before traditional imaging methods detected problems. The technique appears sensitive enough to catch the disease when intervention remains possible, potentially expanding the window for emergency surgery or medical treatment.

The work represents a collaboration between biomedical engineers and neonatologists seeking tools that match the fragility of their smallest patients. Preterm infants already endure multiple stressors in the NICU, from ventilators to frequent blood draws. A radiation-free diagnostic that works quickly addresses a genuine clinical need.

The team now plans clinical trials with human patients to confirm the findings and refine the imaging protocols. They must verify that the optical signatures hold up in real NICU conditions, where patient size and skin pigmentation vary widely and equipment crowding complicates positioning.

If successful, this technology could reshape NEC management in neonatal care. Early detection might shift treatment from emergency
