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.
  1. Brain scans differentiate two types of empathy
    From fMRI scans, researchers find distinct brain markers for empathic care and empathic distress and show that they link differently to eight emotions.

  2. Shutting down part of our brain can make us more creative
    New research uses a cutting-edge technique to better understand the neurological underpinnings of creativity, and finds that a certain brain area is key.

  3. Beyond broken bones, CTs also detect frailty and predict survival
    Using computed tomography (CT) to evaluate muscle health may help identify optimal treatments for older patients who fall and break their hips, a new study led by radiologists from UC Davis and Wake...

  4. Brain scans may help clinicians choose talk therapy or medication treatment for depression
    Researchers from Emory University have found that specific patterns of activity on brain scans may help clinicians identify whether psychotherapy or antidepressant medication is more likely to help...

  5. MRI use may "change the equation" for prostate cancer screening
    Screening for prostate cancer is controversial. It can save lives, but it can also lead to unnecessary diagnoses, followed by surgical or radiation procedures, which themselves may lead to severe...

  6. How blind people's brains rewire to improve other senses
    Breaking research shows how the brains of blind people are naturally rewired to compensate for the lack of visual input, boosting the remaining senses.

  7. Electrical brain stimulation found to improve working memory
    Scientists use transcranial alternating current stimulation to improve working memory. The findings may one day help patients to recover from brain injury.

  8. MRI scans can help spot HIV in the brain
    Scientists at UCL have developed a way to use MRI scans to help identify when HIV is persisting in the brain despite effective drug treatment.

  9. Screening MRI benefits women at average risk of breast cancer
    MRI screening improves early diagnosis of breast cancer in all women-not only those at high risk-according to a new study from Germany published online in the journal Radiology.

  10. Stop using ultrasound to speed up fracture healing, advise experts
    New evidence suggests that receiving low intensity pulsed ultrasound (LIPUS) to speed up bone healing after fracture has little or no impact on pain or recovery time, say a panel of international...

  11. Algorithm predicts whether high-risk babies will develop autism
    Predicting whether someone will go on to develop autism is currently impossible. A new algorithm that measures brain development may change this.

  12. What Tests Are Used to Diagnose Multiple Sclerosis?
    Learn about the different tests that are available and may be used to diagnose MS. When should someone see a doctor and what treatments may be applicable?

  13. New PET imaging technique may help monitor neurological disease progression
    Olfactory neurons in the nasal cavity are the primary source of our sense of smell. Unlike many types of neurons, olfactory neurons are continuously generated throughout the adult lifespan.

  14. Multiple Sclerosis and Radiology: What Tests Are Used to Make a Diagnosis?
    What is the role of radiology in a multiple sclerosis diagnosis and what tests may aid a diagnosis? What do radiology test results mean?

  15. Ultrasound may enhance delivery of RNA molecules to treat GI disorders
    A new study shows that ultrasound enhances delivery of RNA strands into the colon cells of mice with colitis to block production of inflammatory protein.

  16. One in four men with suspected prostate cancer could avoid unnecessary biopsy if given an MRI scan first, study estimates
    Giving men with suspected prostate cancer an MRI scan could improve diagnosis and save those who do not have aggressive cancers from having an unnecessary biopsy, according to a study published in...

  17. 'Emotional hangover' may influence future memory formation
    The more emotional an experience is, the better we remember it. But do emotional states have a delayed effect on our ability to form new memories?

  18. New ultrasound technique is first to image inside live cells
    Researchers at The University of Nottingham have developed a break-through technique that uses sound rather than light to see inside live cells, with potential application in stem-cell transplants...

  19. Runners may have superior brain connectivity, study finds
    Endurance runners' brains have been shown to have greater functional connectivity in several areas, compared with people who are less active.

  20. High-fat diet before imaging improves diagnosis of cardiac sarcoidosis
    Researchers at the University of Illinois at Chicago were able to reduce uncertainty in diagnosing cardiac sarcoidosis by having patients consume a high-fat, low-sugar diet for 72 hours prior to...

  21. Imaging links structural brain changes and cognitive decline in Parkinson's
    People with Parkinson's disease and cognitive impairment have disruptions in their brain networks that can be seen on a type of MRI, according to a study appearing online in the journal Radiology.

  22. Bone marrow cancer: Noninvasive detection steps closer
    For the first time, researchers show that noninvasive, T2-weighted MRI can detect pre-fibrotic stages of the bone marrow cancer myelofibrosis in mice.

  23. Breast-friendly, radiation-free alternative to mammogram in the making
    New method identifies cancerous tumors by blood vessels structure.Each year around a million women in the Netherlands undergo mammograms for early detection of possible breast cancer.

  24. MRI shows brain disruption in children with PTSD
    Children with post-traumatic stress disorder (PTSD) experience disruptions in the structure of the neural networks inside their brains, according to a study appearing online in the journal...

  25. Ultrasound after tibial fracture surgery does not speed up healing or improve functio
    Time to abandon this ineffective treatment, says linked editorial. Receiving ultrasound after surgery to repair a fractured tibia (shinbone) does not accelerate healing or improve functional...
