Quantifying the damage caused to specific parts of the heart by cardiac arrest is key to providing effective treatment and accurate prognoses for millions of people worldwide. Now, researchers have developed a computational method that uses magnetic resonance imaging data to assess the extent of damage to the left ventricle, the heart’s powerhouse.

Lung cancer screening programs that utilize standardized reporting and include cardiothoracic surgeons as part of a multidisciplinary team can successfully be adopted into clinical practice without an increase in surgical intervention for non-cancerous disease, according to an article.

International radiological bodies have agreed on a standard for how doctors evaluate MRI to confirm a diagnosis of prostate cancer. This promises to reduce the number of over diagnosis of insignificant cancers by to up to 89%. The new procedure also allows radiologists to identify up to 13% more life-threatening tumors than current procedures.

Infrared thermography can help detect joint inflammation and help improving work ergonomics, according to a recent study. All objects with a temperature above absolute zero emit infrared radiation as a result of the thermal motion of their molecules. Infrared thermography (IRT) is an imaging modality that can be used to detect this thermal radiation. Human skin emits infrared radiation almost like a perfect black body, and IRT is thus well suited for the measurement of skin temperature. However, although the human core temperature may be indicative of several bodily dysfunctions, there is still a lack of scientific evidence about which musculoskeletal diseases or conditions can be diagnosed by evaluating skin surface temperature with IRT. Nonetheless, since it is a non-invasive and straightforward technique, IRT may represent a cost-effective alternative to the more traditional imaging modalities.

A new DNA stain that can be used to image living cells has been created by scientists. The new stain works by binding to a part of the DNA helix known as the "minor groove." Once bound, it turns on and emits a bright fluorescent red light.

Researchers have found the presence of neurons in the human brain which can each selectively respond to an intermediate color; not just neurons of red, green, yellow and blue.

Scientists have been exploring new ways to 'smell' signs of cancer by analyzing what's in patients' breath. In a new study, one team now reports new progress toward this goal. The researchers have developed a small array of flexible sensors, which accurately detect compounds in breath samples that are specific to ovarian cancer.

Experts experienced in breast cancer care continue to recommend that women start getting annual mammograms at age 40. Breast cancer remains the second leading cause of deaths among women in the United States. Deaths are highest among women who are not screened regularly and have their cancers found at later stage.

A magnetic resonance breast imaging technique that uses no ionizing radiation or contrast agent could reduce unnecessary biopsies by providing additional information about suspicious findings on X-ray screening mammography, according to a new study.

There is a strong correspondence between a particular set of connections in the brain and positive lifestyle and behavior traits, according to a new study. The researchers point out that their results resemble what psychologists refer to as the 'general intelligence g-factor': a variable first proposed in 1904 that's sometimes used to summarize a person's abilities at different cognitive tasks. While the new results include many real-life measures not included in the g-factor -- such as income and life satisfaction, for instance -- those such as memory, pattern recognition and reading ability are strongly mirrored.
