Overview
- Gadolinium-enhanced MRI is also a non-invasive diagnostic modality that has the advantage of no contrast exposure.
- Meaney et.al. examined 30 patients with suspected PE via angiography and Magnetic Resonance Angigraphy (MRA).
- 8 patients had + PA grams, and MRA identified all 5 lobar emboli, in addition to 16 of 17 segmental emboli.
- Another potential benefit of MR, is that is incredibly sensitive, perhaps even better than contrast venography, in imaging clot in the inferior vena cava (IVC) and pelvic veins, and these images can be obtained at the same time as the lung scan.
- Additionally, although MR is more expensive than V/Q scanning, when one takes into account the high number of indeterminate findings on V/Q, the effective cost per diagnosis may be cheaper with MR.
- Meaney et.al. examined 30 patients with suspected PE via angiography and Magnetic Resonance Angigraphy (MRA).
- It needs to be pointed out, that although the criticism of using CT and MR angio lacks sensitivity when examining the subsegmental arteries, inter-reader agreement was only 66% with pulmonary angiography in PIOPED.
