EasyCoronaries: stunning 3D views and easy to perform

Clinical News
MRI NetForum Team Philips Healthcare Philips Global


EasyCoronaries (works-in-progress) may provide a fast and easy alternative to present coronary MRA techniques. The stunning 3D volume rendering of the whole heart affords a clear overview of the coronaries and surrounding anatomy in one glance. Supported by Philips' new Achieva system, EasyCoronaries may present an attractive alternative to CT coronary angiography.

EasyCoronaries is the result of international collaboration between scientists and clinicians. Oliver Weber, Ph.D., Charles Higgins, M.D., and Philips clinical scientist Alastair Martin, Ph.D. at University of California-San Francisco, developed the whole-heart scan protocol. The Japan MR Clinical Science team of Marc Van Cauteren, Ph.D. worked together with Hajime Sakuma, M.D., Matsusaka Central Hospital of Mie University, Japan, to optimize the protocol and pioneer the 3D volume rendering representation of the data.

How EasyCoronaries works

The new coronary MRA technique provides easier planning, shortened examination time and a more intuitive image display. It combines Philips' unique MotionTrak Plus package and a new 3D volume rendering technique.


EasyCoronaries eliminates meticulous planning of individual vessels trees. Instead, it simply covers the entire heart with ultra-thin axial slices. The whole heart 3D scan is a free-breathing B-TFE acquisition using respiratory navigators, VCG triggering and a nearly isotropic reconstruction resolution of 0.5 x 0.5 x 0.75 mm. Total scan time is just 7-15 min. The volume rendering is performed with only 5-10 minutes of user interaction.


The resulting EasyCoronaries 3D views are crisp and clear, showing remarkable similarity to actual anatomical pictures. Moreover, the method requires no contrast agents and is extremely easy to use.


Philips' EasyCoronaries with 3D volume rendering is currently under clinical evaluation at various Philips luminary sites.
