Researchers were not able to compare the two methods to ultrasound techniques or each other due to the small sample size. They hope to accomplish those comparisons through a larger future trial.
“This pilot research shows us that these models work, as all areas of the flap can be assessed using CT and MRI, unlike doppler and skin paddle where some areas may be blind to evaluation,” said Yoshiaki Ota, M.D., lead author of the paper and a neuroradiology fellow at University of Michigan Health. “We know that using CT and MRI could help shorten a patient’s hospital stay or avoid a prolonged hospitalization, and now we need to look further at which is more effective and cost-effective.”
