Magnetic resonance imaging (MRI) has come a long way since the technique was first used in the U.S. in the late 1970s. UConn Health is now taking this powerful, non-invasive imaging tool to the next level.
UConn Health physicians in a variety of specialties are using the technology — which captures images of the inside of the body using a large magnet rather than radiation — in new ways to detect and monitor illnesses.
Dr. Peter Albertsen, chief of UConn Health’s Division of Urology, currently follows 100 patients with localized prostate cancer, which is slow-growing, using advanced multiple-parametric MRI imaging. The technology has now replaced ultrasound as the imaging method of choice for prostate cancer. The technique yields multiple imaging sequences of the prostate, providing information about the anatomy, cellular density measurement, and vascular supply.
There is growing evidence to support the idea that the best treatment plan for low-grade prostate cancer is “watchful waiting” to monitor its progression, instead of immediate surgery or radiation. Albertsen’s practice of active surveillance, and not intervention, for localized prostate cancer was reinforced by a recent long-term study published in September in the New England Journal of Medicine, on which Albertsen served as a consultant.
The technology is extraordinarily helpful, allowing us to avoid invasive biopsy testing and associated risks of bleeding and infection.
UConn Health is the first in Greater Hartford to use MRI to measure the stiffness of patients’ livers to reveal disease without the need for biopsy. Its MR elastography technique involves placing a paddle on a patient’s skin over the liver during MRI to create vibrations and measure the velocity of the radio waves penetrating the organ. This can indicate a stiffer liver and help diagnose fibrosis, cirrhosis, a fatty liver, or inflammation associated with hepatitis. The initiative is led by Dr. Marco Molina, radiologist in the Department of Diagnostic Imaging and Therapeutics.
“The technology is extraordinarily helpful, allowing us to avoid invasive biopsy testing and associated risks of bleeding and infection,” Molina says. “Plus, with the obesity epidemic, patients developing nonalcoholic steatohepatitis (NASH), or fatty liver, can receive earlier diagnosis and take action to reverse their disease’s progression with diet and exercise.”
The new Women’s Center at UConn Health has opened its state-of-the-art Beekley Imaging Center, featuring advanced breast cancer screening. Dr. Alex Merkulov, associate professor of radiology and section head of women’s imaging, and his team are conducting research to test the effectiveness of using an abbreviated, five-minute MRI scan to confirm or rule out a breast cancer diagnosis. Typically, an MRI test takes 20 minutes, but researchers are seeing that a briefer MRI scan of just a few minutes can help provide a definitive answer to whether an abnormal breast growth is cancer or not — and potentially help women avoid the biopsy process.
The UConn Musculoskeletal Institute is now researching the use of MRI to assess and map the strength, weakness, and underlying makeup of a patient’s cartilage, especially for those with arthritis. The tool can allow orthopedic experts to identify any thinning or loss of cartilage in the body, which signifies moderate to late-stage disease. In early stages of arthritis, MRI can help pinpoint early morphological and subtle biochemical changes in cartilage.
In neuroradiology, UConn Health is using the power of MRI to differentiate brain tumors, to detect strokes, to assess dementia, to diagnose multiple sclerosis, to evaluate traumatic brain injury, to find the source of epilepsy, and to guide brain surgery. In March 2017, leading neuroradiologist Dr. Leo Wolansky joins UConn Health to advance its research and chair the Department of Diagnostic Imaging and Therapeutics. Wolansky’s neuroimaging research has focused on enhancing understanding of MRI and its contrast agents, especially for multiple sclerosis and brain tumors. He also specializes in the hybrid imaging modality PET-MRI.
“Thanks to the power and advancement of MRI, doctors can see early evidence of disease and seize the opportunity to intervene and improve their patients’ health,” Molina says.
