A New Way of Diagnosing Mild TBIs

Researchers have developed a novel brain imaging method to diagnose mild traumatic brain injuries (mTBIs), which are often missed by standard techniques like MRI. This method involves loading gadolinium, a common MRI contrast agent, into micropatches attached to immune cells called macrophages. These cells migrate to areas of brain inflammation caused by mTBIs, enabling MRI detection. The technique, called M-GLAMs, was successfully tested in mice and pigs, showing promise for accurately diagnosing mTBIs. It also allows imaging at lower gadolinium doses, potentially benefiting patients with kidney issues. While unable to pinpoint injury locations, M-GLAMs could aid in identifying and treating brain inflammation. The researchers aim to bring this technology to clinical trials, with support from grants and intellectual property protection.

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.

Sarcoma & Bone Cancer Awareness Month: Newest Technology in Imaging

July is Bone Cancer and Sarcoma Awareness Month. According to the American Association for Cancer Research, in 2021, around 13,000 Americans will be diagnosed with soft tissue sarcoma, while 3,600 will be diagnosed with bone cancer. Luckily, the 5-year survival rate of both types of cancer is fairly high (65 for soft tissue and 66.8 for bone). In a comprehensive study from 1978 to 2004, the survival rate of these types of cancers has improved dramatically, thanks in part to improvements in imaging and early detection.

Advances in Radiography

While x-ray technology has been used in a health context since 1899, many features surrounding it have changed. X-rays are now more defined with higher resolution, allowing doctors to zoom in to see smaller tumors and other issues. In fact, this past year, scientists at the University of Erlangen-Nuremberg have broken the record for x-ray resolution, down to under 10 nanometers. Furthermore, the process of obtaining can now be digitized, rather than having to use a darkroom to develop scans. These developments make radiology more accessible to patients and provide more immediate results, which helps bone cancer and sarcoma patients get diagnosed earlier when time is of the essence. There are multiple types of radiography used in diagnosing these types of cancer, and specific advances have emerged and evolved the diagnostic process for each type.

Bone Scans

During bone scans, a patient is injected with a tracer that allows oncologists to see abnormalities. Recent changes in bone scans allow doctors to quantify the metastasis of a bone from a scan. Bone scans can sometimes occur as a diagnostic tool before a CT scan, PET scan, or MRI.

CT Scans

CT scans can be ordered with “contrast,” where the patient swallows or takes an IV containing a dye. This can help doctors see certain organs more clearly. These scans can also help doctors see a cross-section of parts of the body and different perspectives of organs than they’d be able to see with a typical x-ray. The latest advancements in CT scans now offerlower radiation exposure by splitting the x-ray beams, making these procedures safer than ever.

PET Scans

Positron emission tomography (PET) imaging is an emerging tool for bone cancer patients receiving radiation treatments. This tool is now being used increasingly by doctors to monitor tumors between treatments. These advanced scans allow more doctors to receive more information, including receptor expression and metabolism of a tumor. This information helps doctors to understand whether or not a particular type of treatment is working to shrink tumors and to help assess the appropriate dosage.

MRI Scans

Magnetic resonance imaging or MRI scans help oncologists to see the extent of bone and soft tissue cancers by taking cross-sections of affected organs and allowing them to be displayed at different angles. These are taken around a patient while a patient lies still inside a long tube. The most recent changes in MRI technologyhave occurred on the software side. One relevant change includes faster scan times, thereby reducing costs and discomfort for the patient. Furthermore, multiple layers of contrast can now be taken from a single scan, allowing doctors to highlight different issues easily.
