The MEG scanner is very quiet. Parents or others accompanying the patient can wait in the radiology waiting room.
The physician who ordered the MEG scan will receive the results.UT Southwestern’s physician-scientists use MEG technology in ongoing research to improve patient care, with studies that help:Search for opportunities to participate in a clinical research study.We’re one of the world’s top academic medical centers, with a unique legacy of innovation in patient care and scientific discovery.
