Cardiac MRI is proving useful to evaluate cardiac wall motion and to assess cardiac muscle viability in ischemic heart disease.
Is preferable to CT for evaluating adrenal masses such as pheochromocytoma and for helping to distinguish benign and malignant adrenal masses.
Is preferable to CT for evaluating pituitary lesions and parasellar pathology.
