The results translated into the highly-successful 1. 5T MRI product-line of well over 20, 000 systems today.

Bottomley did the first localized MRS in human heart and brain.

After starting a collaboration on heart applications with Robert Weiss at Johns Hopkins, Bottomley returned to the university in 1994, as Russell Morgan Professor and Director of the MR Research Division.

Although MRI is most commonly performed at 1. 5T, higher fields ( such as 3T ) are gaining more popularity due to the increased sensitivity and resolution.

In research laboratories, human studies have been performed at up to 9. 4T and animal studies have been performed at up to 21. 1T
