Magnetic resonance provides insights into pharmaceutical effects.

using MRI to evaluate serial changes in myocardial contractile function (EDV, ESV, EF and regional thickness and thickening) using RF tagging to assess changes in myocardial stress and strain using magnetic resonance angiography to evaluate changes in the luminal size and in plaque morphology (and possibly character) in larger arteries such as the aorta, carotids and iliacs assessing regional myocardial perfusion (under development, but close) evaluation of change in myocardial energetics using PCr/ATP ratio at rest and with stress (see my editorial from last month; 1).
