Device·ITAdvancement of MRI time reduction technology, greatly enhancing clinica

Posted by Jasper Nissim on February 26th, 2021

Worldwide, healthcare is changing from treatment-oriented to prevention-oriented. As regular health check-ups become an essential element of health management, more than 5 million people are undergoing CT and MRI tests annually. The medical and healthcare industries are concentrating on lowering the socio-economic cost of diseases and implementing faster and more accurate imaging diagnosis.

MRI, called magnetic resonance imaging, uses a magnetic field to implement precise internal images of the body. After the examinee enters a large magnetic container, the high frequency generated by the equipment is used to resonate the hydrogen nucleus in the body part to measure the difference in the signal from each tissue. This measurement data is reconstructed with a computer and imaged.

CT is the center of a cross-sectional image of the human body horizontally cut, but MRI can obtain image cross-sections in various directions, such as horizontal, vertical, and oblique lines, without changing the patient's posture. In addition, the soft tissue contrast in the body is excellent, which is advantageous for viewing the brain, spine, muscles, and ligaments, and biochemical information on tissues containing hydrogen atom nuclei can be obtained. Above all, unlike CT, which uses radiation, it has the advantage of being a safe test using high-frequency harmless to the human body.

Long test time is a stumbling block behind MRI's outstanding clinical value

Despite such excellent clinical value, MRI has a problem in that it takes a long time from imaging to image acquisition. This is because the image data is sequentially obtained line by line while encoding several cross-sectional directions in the frequency domain during shooting. Reducing the acquisition time reduces the amount of data collected and reduces the resolution.

The quality of MRI images has improved to a high level overall as image information processing software technology has rapidly developed. However, the inspection time is still longer than other imaging equipment, which is an obstacle to the widespread use of the equipment. CT scans generally take 5 to 10 minutes, but MRI takes 30 to 1 hour.

There are patients who often feel uncomfortable because they have to be examined without moving for a long time in a small space. In particular, children, the elderly, and patients with obstructive phobia who are unable to lie still for a long time often have to retest because the image quality deteriorates due to movement during the examination.

According to the results of the survey, about 700,000 people undergo MRI every year, but 10% of them are re-imaged at other institutions within 30 days. The healthcare industry is striving to develop technology to shorten the examination time to reduce cost loss and examination inefficiency caused by MRI re-examination, and to provide MRI benefits to more patients.
