Imaging Yields Evidence of Heart Disease in Archeological Find — Preserved hearts dating back to the late 16th century or early 17th century were examined using modern imaging techniques. Using MRI and CT, researchers were able to identify different heart structures, such as chambers, valves and coronary arteries. Once the tissue was rehydrated, researchers were better able to identify myocardial muscles with MRI. Classic techniques, such as dissection, external study and histology, were also used to examine the heart tissues. Plaque and atherosclerosis were found on three of the preserved hearts, leading researchers to believe that present-day health conditions existed in the past.

CT and 3-D Printing Aid Surgical Separation of Conjoined Twins — For the first time, CT imaging and 3-D printing technology were combined to help plan the surgical separation of conjoined twins. Researchers performed volumetric CT imaging on both twins to view vital structures and plan how to separate them. To prepare for the separation surgery, doctors performed volumetric CT imaging with a 320-detector scanner, administering intravenous contrast separately to both twins to enhance views of vital structures and help plan how to separate them so that both could survive. The 3-D models proved to be an excellent source of information, as there were no major discrepancies between the models and the twins' actual anatomy and the surgery was a success.

Researchers Find Link Between Early-Stage Brain and Heart Disease — Data were analyzed from participants in the Rotterdam Study, a prospective, population-based study designed to investigate chronic diseases in an aging population. Participants in the study underwent brain MRI and blood testing to measure levels of a type of peptide that provides information on early cardiac dysfunction. The researchers evaluated the brain MRI results for markers of early brain disease, including a loss of brain volume, microstructural changes and white matter lesions, which indicate areas of cells that have been damaged by injury or disease. Analysis revealed that higher levels of this peptide were associated with smaller total brain volume and larger white matter lesion volume. The study implies that the heart and brain are intimately linked in the development of disease.

Study Suggests Breast Density Alone Not a Risk Factor for Cancer — Contrary to recent reports, a new study found that high breast density was not a strong independent risk factor for breast cancer. Researchers looked at data from 52,962 mammography exams performed on women ages 50 to 69 over five years. Of 230 detected breast cancers, almost half were from the group with the lowest ranked breast density, while slightly less than 3 percent came from women in the highest breast density category. The study did not find a strong association between higher mammographic densities and a higher risk of breast cancer among postmenopausal women.

Question of the Day:

The headphones patients usually wear while undergoing an MRI don't fit under our new head coil. Can I scan patients safely without them?

Tip of the day:

Power Doppler ultrasound can be used to image low-flow shallow vessels because it is independent of flow direction and angle.
