Chest radiology is a subspecialty concerned with the diagnostic radiology of diseases of the thorax, especially the heart or lungs. Chest radiology, which includes chest angiograms and chest P.E.T scans, is a subspecialty recognized by the American College of Radiology.
A new method of creating radioisotopes could not only eliminate the chronic shortages that the medical world has faced in recent years but also lead to new types of medical imaging and nuclear medicine therapy, according to one of the technique’s developers.

State regulation of radiologic technologists has “little impact on public health and safety” and should be abolished, according to a staff report of an agency of the Texas Legislature.
Christine Lung, vice president of government relations and public policy for the American Society of Radiologic Technologists, begs to differ:
Everyone knows that radiation is a carcinogen. If performed incorrectly, it’s a direct … read more »
A new algorithm greatly reduces radiation exposure from chest CT scans, making it a good choice for screening people who have been exposed to asbestos … except for a possible problem with what researchers called the “unusual appearance” of the images.
Chest CT is often used for lung cancer screening of asbestos-exposed subjects. But it exposes patients to higher radiation doses … read more »
Newer CT scanners drastically reduce the amount of radiation exposure for patients, according to a new study that involved nine sites in the United States and Saudi Arabia.
The researchers compared radiation exposure from first-generation 64-slice single-source and dual-source scanners to that from the new generation of 128-slice dual-source scanners with high-pitch capability. The newer machines reduced overall dosage by 61 … read more »
The pressure seems to be building on the Centers for Medicare & Medicaid Services (CMS) to have Medicare pay for annual low-dose CT lung cancer screening for older at-risk adults.
Both the U.S. Senate and the U.S. House of Representatives have sent letters to CMS backing the coverage. The Senate letter had Senators Dianne Feinstein, D-California, and Johnny Isakson, R-Georgia, as … read more »
A breakthrough at the U.S. Department of Energy’s Lawrence Berkeley National Laboratory in Berkeley, California, could lead to high-frequency ultrasound imaging with up to 1,000 times higher resolution than today’s medical ultrasounds.
Xiang Zhang, PhD, summed up the research this way:
We have demonstrated optical coherent manipulation and detection of the acoustic phonons in nanostructures that offer new possibilities in the development … read more »
Here are three headlines from medical websites:
“Lifetime cancer risks from X-rays for children ‘relatively low'”
“Imaging Hikes Ca Risk in Kids With Heart Disease”
“Kids with complex heart disease at higher risk of imaging-induced cancer”
Each headline (from, respectively, Medical News Today, MedPage Today, and Health Imaging) refers to the same study, conducted by researchers at Duke University. Circulation published an article about it online on … read more »
Technology borrowed from military night-vision goggles can greatly improve imaging of the lymphatic system and promises to help victims of lymphedema, according to research scheduled to be presented at the upcoming Conference on Lasers and Electro-Optics (CLEO:2014).
Researcher John Rasmussen, PhD, didn’t mince words about the implications of the new technique, called near-infrared fluorescence lymphatic imaging (NIRFLI):
We feel that the ability … read more »
MRI use substantially improves breast cancer screening for female survivors of childhood Hodgkin’s lymphoma (HL), according to a Canadian-led study detailed in an article published online today in Cancer.
Women who underwent chest radiation therapy for Hodgkin’s lymphoma have an increased risk of breast cancer. Established guidelines recommend MRI breast screening starting at age 25 or eight years after the chest radiation, … read more »
Is cancer mostly a modern disease, attributable to such unhealthy habits as smoking and spending too much time on the couch?
X-rays and a scanning electron microscope have revealed metastatic cancer in multiple bones of a skeleton that’s more than 3,000 years old. The find provides evidence that the answer to that question is “yes, but,” according to a study published … read more »
