MRI / PET / Ultrasound News From Medical News Today

Medical imaging refers to several different technologies that are used to view the human body in order to diagnose, monitor, or treat medical conditions. Each type of technology gives different information about the area of the body being studied or treated, related to possible disease, injury, or the effectiveness of medical treatment. Methods of imaging may include ultrasound, MRI, pediatric X-ray imaging, medical X-ray imaging, radiography, CT, fluoroscopy and mammography.

    Learn all about testicular ultrasound and its uses. This article explains the procedure, what to expect, and how to prepare for your scan.

  2. Stroke: Could looking into the eyes help with diagnosis?
    A contrast agent given to stroke survivors undergoing MRI brain scans can leak into the eyes and may help to improve diagnosis and treatment.

  3. Cancer breakthrough: Novel approach can 'starve' tumors to death
    Current research investigates the potential of an experimental compound in causing cancer cell 'starvation' by depriving them of access to a key nutrient.

  4. How writing could make you more altruistic
    Researchers reveal that writing about feelings of gratitude in a journal increases altruism in participants who favor charitable giving over themselves.

  5. Could a spinal fluid test help to diagnose migraine?
    After finding a link between higher levels of sodium in cerebrospinal fluid and migraine, researchers suggest it be investigated as a means of diagnosis.

    Magnetic resonance imaging, or MRI, may be used to identify abnormal tissue and tumors. Learn how to prepare for a breast MRI, the risks, and how it works.

  9. Adult brains undergo structural changes earlier than we thought
    Contrary to common belief, the human brain undergoes structural changes during early to mid-adulthood, according to an analysis of scans of white matter.

  10. Multicolor MRIs could aid disease detection
    Researchers at Case Western Reserve University School of Medicine have developed a method that could make magnetic resonance imaging - MRI - multicolor.

    In the first major study of its kind, researchers using MRI have identified structural abnormalities in the brains of people with one of the most common genetic causes of autism, according to a new...

  12. MRI contrast agents accumulate in the brain
    The International Society for Magnetic Resonance in Medicine (ISMRM) has provided new guidance in the use of contrast agents during MRI scans.

  13. Depression may alter brain's white matter structure
    In a major study that uses cutting-edge imaging, researchers show that people with depression have alterations in the white matter part of the brain.

  14. Smokers who receive CT lung screening are more likely to quit
    Smokers who undergo a CT scan of their lungs are more likely to quit than those who don't, concludes a trial led by Cardiff University.

  15. Metal-free MRI contrast agent could be safer for some patients
    New agent could be used for certain high-risk groups and may enable longer-term tumor imaging.
