Advances in MRI Technologies (Technical Insights)
Frost & Sullivan, June 2005
Magnetic Resonance Imaging Developers Iron out Initial Technology Deficiencies to Create Sophisticated Solutions
With the ever-increasing demand for patient comfort, the need for replacing conventional closed magnetic resonance imaging (MRI) systems with open MRI systems has intensified in the last few years. Physicians prefer an open MRI scanner because it eliminates concerns such as patients’ claustrophobia, size, and weight. Since many technology developers are taking to the concept of open MRI with higher field strength, physicians are able to conduct faster, hassle-free scans that also provide better image quality and often, higher accuracy. This kind of technology revolution in medical imaging benefits both patients and physicians. Moreover, MRIs’ unique ability to image both anatomically and functionally is finding the technology new applications in surgical planning and navigation, as well as diffusion and perfusion imaging.
This Technical Insights study provides an overview of advances in MRI. It covers technologies such as MRI magnets, magnetic gradient coil, radio frequency (RF) systems, MRI scanners, and MRI software. It provides technology challenges, market drivers, and restraints, as well as assesses innovations and opportunities in North America, Europe, and the Asia Pacific. The research service enables companies to align their positioning strategies to benefit from these emerging technologies.
MRI Solutions that Offer New Marketable Applications and Increase Productivity Are in Huge Demand
MRI has become the preferred diagnostic imaging method for imaging the central nervous system, particularly for detecting brain tumors, spine lesions, imaging blood vessels, and stroke affected areas of brain. This technology has gained impetus from the keen interest shown in it by technology developers and manufacturers that wish to make it more patient friendly. Not only is it making an impression in diagnostic imaging, it is also fast gaining popularity in cardiac imaging.
Moreover, the ageing population and increasing prevalence of age-related diseases such as cancer, Alzheimer’s disease, Parkinson’s disease, stroke, and heart failure serve both as a market and technology driver, says the analyst of this research. These diseases represent the highest cost burden to healthcare systems in industrialized nations and hence, there is tremendous pressure to develop tests that can assist in early diagnosis and help select the most appropriate treatments in order to reduce costs.
Rapid and Significant Advances in MRI Scanners Dominate Technology Trends in the Industry
MRI scanning is non-invasive and does not use harmful ionized radiation, making it one of the safest imaging techniques available. MRI scans can also be used to take images of any part of the body, in any plane, and they provide more detailed information than X-rays or computed tomography (CT) scans. Furthermore, the MRI contrast materials used for image enhancement have very low incidence of side effects. As the mid- and high-field scanners experience higher adoption rates, sales in low-field scanners are certainly dipping, notes the analyst. The mid- and high-field scanners provide benefits such as additional applications, faster scan times, and increased image quality; thereby, having a greater market impact on MRI.
Once market barriers of tight research budgets, complexity of the instrument, and high costs of MRI scans are resolved, the industry is expected to develop further. With technology developers exploring many new applications, especially those involving cardiac and neuroimaging, it was inevitable that MRI would evolve into a highly sophisticated medical imaging tool. Some of the improvements made to the technology have further enhanced the modality and many applications have adopted these systems.
