'EXCITE technology has the potential to open the door to new imaging techniques and clinical applications, leaping beyond conventional two and three-dimensional MRI to true 4D imaging that will improve the diagnosis of disease throughout the human body from head to foot.' Robert R. Edelman, M.D., Professor of Radiology at Northwestern University Medical School and Chairman, Department of Radiology, at Evanston Northwestern Healthcare.

From GE Healthcare;
The Signa HDx MRI system is GE's leading edge whole body magnetic resonance scanner designed to support high resolution, high signal to noise ratio, and short scan times.
Signa HDx 3.0T offers new technologies like ultra-fast image reconstruction through the new XVRE recon engine, advancements in parallel imaging algorithms and the broadest range of premium applications. The HD applications, PROPELLER (high-quality brain imaging extremely resistant to motion artifacts), TRICKS (contrast-enhanced angiographic vascular lower leg imaging), VIBRANT (for breast MRI), LAVA (high resolution liver imaging with shorter breath holds and better organ coverage) and MR Echo (high-definition cardiac images in real time) offer unique capabilities.

From GE Healthcare;
three dedicated MRI systems - a neuro imager, a cardiovascular system, and a whole body scanner - all in one system.

From Siemens Medical Systems;
the MAGNETOM Concerto is easy to site and has low life cycle costs due to the permanent magnet. The powerful gradient system with 20 mT/m and a slew rate of 40 T/m/s permits high field applications on a low field open MRI system. The three-sided fully open magnet results in maximum acceptance of claustrophobic or anxious patients and patient access.

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.
