Discovery MR450 Does Real-Time Cardiac Imaging

GE Healthcare's 1.5T magnetic resonance (MR) scanner, Discovery MR450, offers some of the most advanced capabilities available on any 1.5T system, including real-time cardiac imaging, single-acquisition, multi-contrast abdominal images with outstanding fat/water separation and ultra high-resolution musculoskeletal exams with high patient throughput.

Built around the company’s proven short-bore, superconducting 1.5T magnet — the Discovery MR450 delivers high homogeneity for excellent results even when imaging with a large or off-center field of view (FOV). Workflow and productivity issues are also addressed with the new system with gains of up to 60 per cent additional anatomical coverage and resolution per unit time compared to conventional systems, increased acquisition speed over previous generations of 1.5T systems.

GE’s Discovery MR450 features several new advanced applications, including: SWAN (T2 Star Weighted Angiography), which combines a unique 3D T2-based multi-echo acquisition with a special reconstruction algorithm. It generates several echoes, which are read out at different TE times, and compiles magnetic signatures of a range of tissues with varying degrees of T2 contrast.

With SWAN, users can visualize major vessels and large vascular structures, accurately delineate small vessels and microbleeds, assess iron and calcium deposits in tissue and image the whole brain in 3D high resolution in just 4 minutes.

The new GE suite of Inhance Non-Contrast Enhanced MR Angiography (MRA) applications is robust, fast and easy to use. Inhance sequences deliver consistent, reproducible images even in difficult-to-scan anatomies, for fewer rescans and confident differential diagnoses.

Rafael Rivero, M.D., Global Head of Medical Affairs at MSI, said: "The importance of MyoStrain cannot be understated because of the test's immense clinical value and ability to quantify intramyocardial dysfunction across 48 segments of the heart. In a six-heartbeat MRI scan, MyoStrain arms physicians with novel clinical information about a patient's heart health."

High resolution in-vivo MR-STAT using a matrix-free and parallelized reconstruction algorithm being developed by Philips and UMC.

In-vivo T1, T2 and proton density maps reconstructed with MR-STAT using eight (first column), four (second column), two (third column) and one (fourth column) of the acquired k-spaces in the reconstruction. The acquisition times were 13.6, 6.8, 3.4 and 1.7 seconds respectively on a 1.5T Philips Ingenia MRI system. Find more images and information in this article.[1]

Fig. 1 The basis of high-sensitivity SPION imaging at ultra-low magnetic fields.

(A) Magnetization of 25-nm SPIONs (green), gadolinium CA (Gd-DTPA/Magnevist, blue), and water (red) as a function of magnetic field strength (B0). (B) Magnetization as a function of magnetic field strength (B0) in the ULF (<10 mT) regime for the materials shown in (A). Superparamagnetic materials, such as SPIONs, are highly magnetized even at ULF. Paramagnetic materials, such as CAs based on gadolinium, and body tissues (which typically have diamagnetic susceptibilities close to water) have absolute magnetizations that increase linearly with field strength. Curves in (A) and (B) were reproduced from data in (3253) and reflect the magnetic moment per kilogram of compound. (C) Highly magnetized SPIONs (brown) interact with nearby 1H spins in water, shortening 1H relaxation times, and causing susceptibility-based shifts in Larmor frequency.
