Abstract
Radiological techniques to image the right ventricle (RV) are difficult, due to complexities of shape of the RV and its relationship to surrounding structures. During disease states, unpredictable changes in the dimensions and shape of the RV make quantitative analysis by conventional techniques difficult. Magnetic resonance imaging (MRI) allows detailed visualization of the shape and internal morphology of the RV and pulmonary arteries and quantitation of indices of RV function. MRI may be invaluable to assess morphological sequelae of congenital cardiovascular malformations and secondary causes of pulmonary hypertension. Recent studies utilizing MRI to diagnose pulmonary thromboembolism are promising. The indications for MRI for pulmonary and cardiovascular conditions continue to evolve. MRI may be a useful, noninvasive adjunct for evaluating suspected right ventricular dysfunction for a host of cardiac and pulmonary disorders.
