Perhaps one of the MRI’s most intriguing applications is in mapping activity inside the human brain, in near real-time. Though the basic technology of MRI is more than a half-century old, these imaging tools continue to improve in sensitivity and resolution, breaking new ground in both fundamental research and therapeutic interventions. In spite of their reputations for being noisy and at times claustrophobic, MRIs are medical marvels with an unparalleled ability to peer safely inside the human body to detect otherwise hidden maladies, like soft-tissue injuries or newly formed tumors.
