Physicians from Oxford University in the U.K. believe they've found a comprehensive and reproducible method of assessing regional wall motion in tissue with phase mapping (TPM) of MRI data, a technique based on phase velocity.

64-slice CTA reliably detects stenoses by patient, less so by vessel and segment
By Eric Barnes
As CT piles on more detector rows, its ability to detect significant coronary artery stenosis is growing apace.
