New Imaging Tech that Captures Neuronal Activity Across the Brain During Recovery

Researchers at Tufts University School of Medicine have developed a novel imaging technology to monitor neuronal activity throughout the entire brain during the initial weeks of recovery from traumatic brain injury (TBI). Their study, published in Cerebral Cortex, reveals that TBI can induce changes in brain function beyond the injury site. Using a combination of fluorescent sensors and electrodes, they observed altered connectivity patterns in mice post-injury, even in regions distant from the impact. Despite the mice’s ability to perform physical tasks normally, their brain activity during both exercise and rest differed significantly from healthy brains. This impaired ability to switch between states suggests underlying brain state dysfunction post-injury. The findings highlight the brain’s plasticity in response to injury and have potential clinical implications for understanding TBI impacts and tailoring treatments. The researchers aim to further investigate long-term neural activity changes post-recovery and explore the technology’s potential in predicting specific dysfunctions or long-term outcomes of TBI.

Recent Advancements in Nuclear Medicine

The medical community is always looking for new and better ways to serve patients and save lives. Science, medicine, and technology often intersect to break barriers and create innovative new treatments – and nowhere is that truer than in the field of nuclear medicine.

What is Nuclear Medicine?

The National Institute of Biomedical Imaging and Bioengineering defines nuclear medicine as a specialty that uses radioactive tracers to diagnose and treat disease. Nuclear medicine is invaluable for patient care, as it can help detect disorders in the bones, gall bladder, heart, and much more.

advancements in nuclear medicine

This field has seen tremendous advancements in recent years, which offer the potential for incredible and life-saving benefits. Here are some of the latest developments in nuclear medicine.

Making AI More Effective

Artificial intelligence has been an integral part of medicine for decades, particularly in the realm of diagnostics. And now, new research suggests that nuclear medicine may make AI-based diagnostics even more effective.

radiology interpretations

For example, researchers in the Journal of Nuclear Medicine (JNM) suggest that nuclear imaging can help with machine learning and AI cancer diagnoses. This is because nuclear imaging creates a high contrast between tumors and normal tissue, making it much easier for the machine to identify abnormalities. Combining AI diagnostics with nuclear medicine can make the machines more accurate, which will ultimately result in better patient care over time.

Detecting Heart Disease

Radionuclide imaging has long been used to detect issues in patient heart function. However, researchers are beginning to explore new uses for this technology – including the examination of the heart’s very molecules.

Research from 2020 found that radionuclide imaging is successful at detecting cardiac amyloidosis, a rare condition in which a protein called amyloid is deposited in the cardiac muscle. Amyloid deposits can cause buildup over time and ultimately lead to heart failure, so it is very important to detect this condition as early as possible.

Discovering New Treatments

Nuclear medicine has many potential uses for imaging and diagnostics. However, it also offers many benefits for researchers.

For example, scientists at the Vanderbilt University Institute of Imaging Science recently used a radioligand (a radioactive substance used to study receptors in the body) to study whether an antioxidant called ERGO could penetrate the brain and protect against oxidative stress. The study successfully proved that ERGO can penetrate the brains of mice, which opens doors for further research on using this antioxidant to treat conditions like Alzheimer’s disease.

Nuclear medicine is always developing and advancing, and each advance makes it easier to give patients the care they deserve.
