A new study shows that the world's firstportable MRI can accurately detect ischemic strokes. The device was approved for use by the US Food and Drug Administration (FDA) in 2020. While the device has been cleared by the FDA for use in the US, researchers are still investigating the best ways to apply it in real-life settings. The latest study looks at how well portable MRI can detect ischemic stroke.
When a patient is admitted to the emergency roomhelp with stroke symptoms, it is important that doctors quickly determine whether the stroke is ischemic or hemorrhagic because treating a suspected ischemic stroke with blood thinners, for example, can be fatal if the stroke was actually hemorrhagic.
Therefore, the aim of the new study wasfind out how accurately portable MRI can detect ischemic stroke. A collaborative effort between researchers at the Yale School of Medicine and Harvard University studied 50 patients at Yale New Haven Hospital.
Each patient underwent a routinemagnetic resonance imaging to confirm the diagnosis of ischemic stroke. They were then scanned with a portable MRI machine, which was able to accurately detect blood clots in the brain in 90 percent of patients.
The portable device has been tested in various emergency department and intensive care settings. It was found that it is able to detect blood clots up to 4 mm in diameter.
