3T pulmonary MR angiography

Purpose: MR angiography has recently benefited from higher signal at high field strength, and developments in parallel imaging, coils, and shared k-space techniques for increased acquisition speed. Still, pulmonary MR angiography is challenging at high field strength due to the geometry of the anatomy and the presence of air-vessel interfaces. Large coverage is needed with high resolution within acceptable breath hold time. Materials and Methods:Contrast-enhanced pulmonary MRA was performed in 8 subjects on a Philips Achieva 3T MR system, using a 6-channel cardiac coil. Gadolinium-BOPTA (Multihance, Bracco) cont…
