Pulmonary Angiogram MRI Protocol

• DB Haste Axial
• TrueFISPAxial
• 3D FLASH Coronal
• Timing Run -Thru main pulmonary artery.
• 3D FLASH Coronal 2 measures (7 sec gap; 2nd run may be done on inspiration) Inject 20cc of Gd at 2cc/sec followed by 20cc saline at 2cc/sec.
• VIBE Axial

VIBE provides a gray scale that enables readers to distinguish between the clot, or thrombus, and the lung, which both appear dark on MRPA. 

The true FISP test does not require contrast agent or a breath hold, an important consideration for embolism patients who often cannot hold their breath long enough for image acquisition on MRPA.
