MRI of the Pulmonary Circulation

In general, MRI is only considered as a second-line imaging tool for the evaluation of lung disease. Among the major disadvantages to CT are the inferior spatial resolution and longer imaging times. Recent technical developments, such as high performance gradient systems, optimised pulse sequences, and parallel imaging techniques have substantially improved the potential of MRI for the assessment of lung disease. The morphology of the pulmonary circulation can be assessed by non-enhanced and contrast-enhanced MR angiography. Contrast-enhanced MR angiography may be performed with high spatial and temporal resolut…
