Optical coherence tomography (OCT) can successfully identify the characteristics of coronary plaques

A catheter-based imaging technology called optical coherence tomography (OCT) can successfully identify the characteristics of coronary plaques in patients with various cardiac symptoms. The report from researchers at Massachusetts General Hospital (MGH) will appear in the journal Circulation.

Confocal imaging promises early detection of skin cancer

Detecting skin cancer early saves lives, but is a job for specialists. A new European system based on confocal imaging promises to improve detection and diagnosis rates by 20 per cent and to speed up the whole process considerably.

New imaging technology may serve as objective outcome measures for orthopedic conditions

New imaging technologies are enabling doctors to not only diagnose a variety of orthopaedic and musculoskeletal conditions with more accuracy, but also to determine with unprecedented precision whether clinical recovery from bone, joint or tendon damage is actually complete and not simply a "placebo effect."

Better ways to heal and regenerate bones using microcomputed tomography imaging

Tissue engineers can choose from a wide range of living cells, biomaterials and proteins to repair a bone defect. But finding the optimum combination requires improved methods for tracking the healing process.

Visual recognition begins with categorization

Take a moment and look at a picture near you. What did you see? How long did it take you to understand what was in the image, meaning how long did it take you to realize the green blob was a tree? Or that the orange circle was a piece of fruit? Most likely you assume that it took you no time at all, you just knew.

Rural imaging center takes aim at medical mistakes in healthcare

Thumb MRI Center is taking the initiative to decrease costly medical errors and increase the quality of healthcare by integrating a patented artificial intelligence technology developed by AIdentity Matrix.

Cardiovascular experts issue blueprint for safer X-Ray imaging

Millions of invasive cardiovascular procedures that involve the use of potentially hazardous X-rays are done in the United States each year.

Breast MRI moderately useful for detecting breast cancer

In women with breast lesions that are suspicious for cancer, based on clinical examination or mammography, performing a breast MRI has high sensitivity but only moderate specificity for detecting breast cancer, but does not necessarily eliminate the need for tissue sampling, according to a study in the December 8 issue of JAMA.

First live imaging of specialized immune system cells reveals new clues about body’s security system

To keep the body safe, the immune system enlists more than one form of protection. A circulating task force of immune system cells monitors the body’s periphery, and sends information back to field command centers — the lymph nodes — located at pivotal traffic points.

Brain imaging shows differences in people at risk for Alzheimer's

Using brain imaging, researchers at Columbia University Medical Center (CUMC) have found clear differences in brain function between healthy people who carry a genetic risk factor for Alzheimer's disease and those who lack the factor.

Study increases likelihood that MRI could be used as predictive technology to determine which patients should be placed on statin therapy for atherosclerosis

Using modified magnetic resonance imaging (MRI) techniques, researchers at Johns Hopkins have been able to detect the early benefits of a cholesterol-lowering medication much sooner than before.

MRI is useful, not just in diagnosing MS, but also in the monitoring of therapies in clinical trials

Progressive changes within the brain occur earlier in multiple sclerosis than previously supposed, according to a study presented October 4, 2004, at the 129th annual meeting of the American Neurological Association.

New imaging analysis techniques to probe causes of dyslexia

Using sophisticated new software that integrates a variety of imaging methods, Wake Forest University Baptist Medical Center researchers will probe the mystery of what causes dyslexia with a four-year, $2.3 million grant from the National Institutes of Health.

Sclerosants in microfoam are the treatment of choice for ulcers of varicose origin

The study brings together the results of more than ten years of monitoring 116 patients affected by varicose ulcers being treated in Granada, Pamplona and Madrid. On comparing these with data from other novel therapies

CA125 blood test may be superior to standard imaging techniques like CT scans

A new study shows that the CA125 blood test, which measures the level of protein produced by ovarian cancer cells in the blood, may be superior to standard imaging techniques like CT scans in predicting survival in patients with recurrent ovarian cancer.

New imaging technique may help cystic fibrosis sufferers

Now, Jefferson Lab scientists have used their expertise to build a small animal medical imager that's helping researchers develop a new gene therapy technique for cystic fibrosis.

A prototype microscope that uses neutrons instead of light to "see" magnified images

A prototype microscope that uses neutrons instead of light to "see" magnified images has been demonstrated at the National Institute of Standards and Technology. Neutron microscopes might eventually offer certain advantages over optical, X-ray and electron imaging techniques such as better contrast for biological samples.

Miniature spectroscopic instruments and software to look at changes that occur within the cells and tissue of the brain

When molecules in cells are stimulated by light, they respond by becoming excited and re-emitting light of varying colors (fluorescence) that can be captured and measured by highly sensitive optical equipment.
