Molecular Breast Imaging (MBI) is a supplemental imaging technology designed to find tumors that would otherwise be obscured by surrounding dense breast tissue on a mammogram. The new breast imaging technique nearly quadruples detection rates of invasive breast cancers in women with dense breast tissue, according to the results of a major study.

It’s very difficult to understand the retinal structure of children because they are known to be uncooperative during eye examinations designed for adults. New explores a new non-invasive technology that’s kind of like a handheld CT scanner for the eye.

With the goal of making it easier for surgeons to detect malignant tissue during surgery and hopefully reduce the rate of cancer recurrence, scientists have invented a new imaging system that causes tumors to “light up” when a hand-held laser is directed at them.

Researchers have designed a nanoparticle that can be detected by six medical imaging techniques: computed tomography (CT) scanning; positron emission tomography (PET) scanning; photoacoustic imaging; fluorescence imaging; upconversion imaging; and Cerenkov luminescence imaging.

Researchers have developed a new technique to safely mark T-cells for non-invasive in vivo imaging to better understand what happens during immune reactions in the body. The immune system's T-cells are a key starting point for researchers developing immunotherapies against cancer and autoimmune diseases. T-cells are constantly on the move throughout the body, checking for invading pathogens and diseased cells. If any of these structures which fit the T-cells' specific receptors like a key fits the right lock -- then the T-cell will proliferate and set off a series of signals, starting the process of eradicating the diseased cell.

A two-minute brain-imaging test that may be able to aid in the diagnosis of children with autism spectrum disorder is currently under development in the United States. Usually, diagnosis -- an unquantifiable process based on clinical judgment -- is time consuming and trying on children and their families. That may change with this new diagnostic test.

Autism is a spectrum of closely related disorders diagnosed in patients who exhibit a shared core of symptoms, including delays in learning to communicate and interact socially. Early detection of autism in children is the key for treatment. Using advanced 3-D imaging and statistical analysis techniques, researchers have identified facial measurements in children with autism that may lead to screening tools for young children and provide clues to genetic causes.

A study of portable ultrasound carried out in the USA, Canada and India has revealed the potential of this technology for detecting plaques in peripheral arteries that can lead to heart attacks and stroke before symptoms arise, in both developed and developing country settings, allowing preventive treatment in those affected.

Recent American federal reports show that physicians are increasingly referring services such as diagnostic imaging to businesses in which they have a financial stake. The controversial practice depends on loopholes in existing law that the new Congress could consider closing, write two doctors.

A new study from Massachusetts General Hospital investigators has found, for the first time, evidence of neuroinflammation in key regions of the brains of patients with chronic pain. By showing that levels of an inflammation-linked protein are elevated in regions known to be involved in pain transmission, the study paves the way for the exploration of potential new treatment strategies and possibly for biomarkers reflecting pain conditions.

Each year more than 12 million Americans visit their doctors complaining of headaches, which result in lost productivity and costs of upward of $31 billion annually. A new study suggests some of that cost could be offset by physicians ordering fewer tests and an increased focus on counseling about lifestyle changes.

Expectant parents should avoid the use of ultrasounds for nonmedical reasons, according to maternal-fetal medicine experts. “Ultrasound is a valuable tool when done for medical purposes by trained professionals,” said one physician. “But this technology should not be used for entertainment purposes to see an image of a baby or to identify gender."

Noninvasive brain scans have led to basic science discoveries about the human brain, but they've had only limited impacts on people's day-to-day lives. A review article highlights a number of recent studies showing that brain imaging can help predict an individual's future learning, criminality, health-related behaviors, and response to drug or behavioral treatments. The technology may offer opportunities to personalize educational and clinical practices.

In 2014, prostate cancer was the leading cause of newly diagnosed cancers in men and the second leading cause of cancer death in men. A team of scientists and physicians now describe a novel imaging technique that measurably improves upon current prostate imaging -- and may have significant implications for how patients with prostate cancer are ultimately treated.

People exposed to asbestos from mining in Libby, Mont., show long-term changes in lung imaging and function tests, even with relatively low asbestos exposure, reports a new study. Thirty years after the Libby mine was shut down, abnormalities are still found on chest computed tomography (CT) scans and lung function tests in more than half of workers exposed to Libby amphibole asbestos (LAA).

Using a different type of MRI imaging, researchers have discovered previously unrecognized differences in the brains of patients with bipolar disorder. In particular, the study revealed differences in the white matter of patients' brains and in the cerebellum, an area of the brain not previously linked with the disorder.

An automated method (much more sensitive than fMRI) to detect the activity of neurons during specific behaviors, at the resolution of individual brain cells throughout the entire mouse brain, has been successfully demonstrated. A team shows brain activation patterns when male mice perform two critical tasks: recognizing other individuals and determining the sex of another individual.

Some patients undergoing lumpectomy surgery for the removal of an early detected breast tumor – the surgical option of choice for this diagnosis -- are benefiting from new intra-operative technology that detects microscopic amounts of cancer cells on removed tumor tissue not visible during or following surgical intervention.
