Which of the following is true regarding cardiac MRI: (A) Infarcted myocardium is hypointense on T2-MRI, (B) Viable myocardium can be differentiated from infarcted myocardium, (C) Prosthetic hea valves are an absolute contraindication for MRI, (D) It is better than CT for non-invasive assessment of coronary aeries
Answer is B. Ans. is 'b' i.e., Viable myocardium can be differentiated from infarcted myocardium.Infarcted myocardium appears hypointense on T1-MRI and hyperintense on T2-MRIViable myocardium can be easily differentiated from infarcted tissue.Prosthetic hea valves are a relative contraindications for MRI.Multislice CT is a better modality than cardiac MRI for the non invasive assessment of coronary aeries.
