From Hitachi Medical Systems America Inc.;
Hitachi expanded its portfolio with the Echelon™ 1.5T. The MRI scanner combines a compact magnet and a scalable 8-channel RF system with high-performance gradients and slew rate to select short echo times, small field of views, high matrices and thin slices. Standard features of the Echelon MRI system include higher-order active shim, RAPID (parallel imaging for use on brain MRI, body, cardiovascular imaging, and orthopedic coils), multiple coil ports, and an advanced reconstruction engine.

Flow phenomena are intrinsic processes in the human body. Organs like the heart, the brain or the kidneys need large amounts of blood and the blood flow varies depending on their degree of activity. Magnetic resonance imaging has a high sensitivity to flow and offers accurate, reproducible, and noninvasive methods for the quantification of flow. MRI flow measurements yield information of blood supply of of various vessels and tissues as well as cerebro spinal fluid movement.
Flow can be measured and visualized with different pulse sequences (e.g. phase contrast sequence, cine sequence, time of flight angiography) or contrast enhanced MRI methods (e.g. perfusion imaging, arterial spin labeling).
The blood volume per time (flow) is measured in: cm3/s or ml/min. The blood flow-velocity decreases gradually dependent on the vessel diameter, from approximately 50 cm per second in arteries with a diameter of around 6 mm like the carotids, to 0.3 cm per second in the small arterioles.

Magnetic resonance imaging of the heart is a diagnostic MRI procedure that is useful to evaluate the structures, the function and viability of the heart and the major blood vessels.

From Philips Medical Systems;
the Intera 3 T high field system, the first with a compact magnet, which is built on the same platform as the 1.5 T, is targeted to high-end neurological, orthopedic and cardiovascular imaging applications with maximum patient comfort and acceptance without compromising image quality and clinical performance. Useable for clinical routine and research. The Intera systems offer diffusion tensor imaging (DTI) fiber tracking that measures movement of water in the brain and can therefore detect areas of the brain where normal movement of water is disrupted.

From Philips Medical Systems;
The Intera Achieva CV is focused on cardiovascular imaging research and development, generating technology on the cutting edge for modern clinical needs, like easy coronary artery imaging, the evaluation of flow effects in vessels and peripheral angiography with optimal resolution per station.
