282PERFUSION DISPARITIES IN OMPHALOPAGUS CONJOINED TWINS: INSIGHTS FROM DIFFUSION-WEIGHTED IMAGING AND APPARENT DIFFUSION COEFFICIENT ANALYSISA study comparing omphalopagus conjoined twins to singleton fetuses makes use of To examine brain and placental perfusional changes of conjoined twins using diffusion-weighted imaging and apparent diffusion coefficient. On omphalopagus conjoined twins and three singletons with borderline ventriculomegaly, MRIs were performed at the same gestational week as the control group. For both the brain regions (p = 0.005) and the placenta (p = 0.005), there was a significant ADC difference between the conjoined twins and the control group (p = 0.018). As a result of reduced perfusion in the placenta and brain of conjoined twins, ADC values might be lower in these organs than in those of singletons. Pregnancies with monochorionic multiples and singletons are more prevalent will be compared in future studies based on our findings Dr Nagateja Bonala@gmail.comResearch1222022Conjoined twins, Omphalopagus, Diffusion-weighted imaging, Apparent diffusion coefficient (ADC)Dr Nagateja BonalaKaturi Medical College and Hospital, Guntur, Andhra Pradesh, India.
