Researchers have developed a new MRI technology that uses xenon gas to generate high-resolution images of the heart and lungs in living laboratory rats. The system detects signals from polarized xenon molecules, allowing for direct measurement of blood flow through organs.
A new imaging device, Hall Effect Imaging (HEI), uses ultrasonic emissions to highlight variations in electrical conductivity between healthy and diseased tissue, offering a faster alternative to painful biopsies. HEI has high specificity, ruling out false positives, and could complement MRI technology.
Scientists at Duke University Medical Center have created microbubbles that can be used to suspend helium gas, allowing for detailed magnetic resonance images of blood vessels. The technique combines strengths of several imaging technologies and could lead to non-invasive studies on vascular health, perfusion, and anatomy.
A 51-year-old man with a rare brain disorder, known as 'sagging brain,' was treated at UCSF after initial diagnoses failed to provide relief. Exhaustive neurological scrutiny led to the discovery of a ruptured cyst causing the condition, which was successfully treated through surgery.
Researchers found that contrast echocardiography can detect blockage of small vessels leading to reduced tissue blood flow after a heart attack. The study validated the effectiveness of CE in measuring post-heart attack small vessel obstruction and compared it favorably to MRI.
Scientists at Johns Hopkins have developed a new noninvasive test that measures creatine levels in the heart, which can indicate muscle damage from a heart attack. The test uses MRI and MRS to pinpoint depleted concentrations of creatine in injured heart tissue.
Researchers found that only three of 39 physicians ordered an MRI for a patient with low yield, while others suggested it in the future or referred her to a neurologist. Physicians often failed to use recommended communication skills, such as asking about the patient's friend's experience with MS.
Research findings show decreased benzodiazepine receptor binding in the left temporal pole among patients with GAD, indicating a potential link between brain structure and anxiety. The study's results suggest that high regional heterogeneity may be necessary for adaptation to living organisms.
A new study reveals that transcranial sonography is more sensitive than MRI and CT in detecting residual tumors and predicting patient survival after brain tumor surgery. This non-invasive imaging technique offers advantages, including lower cost, portability, and ease of use, making it a valuable tool for follow-up care.
Researchers found ultrasound can accurately diagnose disc bulges and herniations, as well as detect soft tissue abnormalities. This non-invasive technique may help document clinical problems and reduce healthcare costs compared to MRI.
A team of researchers from Bowman Gray School of Medicine used sonography to analyze the anatomy of healthy subjects and define normal spinal and paraspinal structures. The study aims to improve the interpretation of sonographic images in patients with back pain.
A non-invasive method for distinguishing between different types of tumors has been developed by Prof. Hadassa Degani at the Weizmann Institute. The approach, known as the Three Time Point method, uses MRI to monitor the uptake and clearance of a contrast-enhancing dye-like material in tumor tissue.
A new test apparatus developed by Purdue researchers allows for faster, more precise MRI scans without causing discomfort to patients. The system enables doctors to gather images from previously hard-to-scanned areas like the liver and view transient phenomena like cardiac activity in a noninvasive way.
Researchers at the University of Rochester are developing augmented reality technology that can seamlessly combine virtual and real-world images. This technology has numerous applications in medicine, entertainment, maintenance, and defense, including improved surgeries, enhanced soldier capabilities, and streamlined repairs.
A new type of MRI scan called dynamic kinematic MRI imaging has been shown to accurately diagnose joint problems, including knee, ankle, and temporomandibular joint issues. This technology allows doctors to pinpoint the exact point in range of motion where the problem occurs, enabling more precise diagnoses and treatment options.
Researchers have developed a rapid nuclear magnetic resonance imaging (MRI) test that can measure heart cell damage from heart attacks in living animals. The new method quickly measures damage to the heart when blood flow stops and restarts, producing sodium 'maps' of the heart.
University of Washington researchers have made significant advances in a new MRI technique called magnetic resonance (MR) neurography. This breakthrough allows for clear images of nerve compressions, injuries, and normal nerve function, enabling diagnoses and treatment with unprecedented precision.
The new technology uses parallel computing to analyze reflected sound waves, creating three-dimensional images quickly enough for clinicians to view a whole human heart as it beats. The system also enables doctors to electronically dissect and display selected slices of medical interest on a computer screen.
A new study published in The Journal of Plastic and Reconstructive Surgery found that non-invasive magnetic resonance angiography (MRA) and magnetic resonance imaging (MRI) can effectively manage vascular malformations. The imaging techniques showed the growths' connections to surrounding tissues, allowing for better treatment planning.
