Radiology News and Research

RSS

Radiology is the medical specialty directing medical imaging technologies to diagnose and sometimes treat diseases. Originally it was the aspect of medical science dealing with the medical use of electromagnetic energy emitted by X-ray machines or other such radiation devices for the purpose of obtaining visual information as part of medical imaging.

Magnets in toys pose serious health risks

While the danger of magnets for children is increasingly recognized, they don't receive treatment for swallowing them as quickly as needed, and parents don't receive sufficient warning on toys, according to a new study.

Novel angled gantry approach reduces breast radiation exposure

A novel angled gantry approach to coronary CT angiography reduced radiation exposure to the breast by more than 50%, according to Thomas Jefferson University researchers.

Stress-related disorders affect brain's processing of memory

Researchers using functional MRI (fMRI) have determined that the circuitry in the area of the brain responsible for suppressing memory is dysfunctional in patients suffering from stress-related psychiatric disorders.

Robotic help for stroke patients

Research scientists using a novel, hand-operated robotic device and functional MRI (fMRI) have found that chronic stroke patients can be rehabilitated, according to a study presented today at the annual meeting of the Radiological Society of North America (RSNA).

Radiologists diagnose and treat self-embedding disorder in teens

Minimally invasive, image-guided treatment is a safe and precise method for removal of self-inflicted foreign objects from the body, according to the first report on "self-embedding disorder," or self-injury and self-inflicted foreign body insertion in adolescents.

Cancer risk from cardiac computed tomography overstated

Radiology and cardiovascular researchers from the Medical University of South Carolina in Charleston, S.C., today present new data that shows the risk of cancer from exposure to radiation during computed tomography for cardiovascular disease has been overstated and that new estimates are several times lower than previously published conclusions.

Portable eight-slice CT in ER increases chance of stroke survival and recovery

New research has found that the availability of a portable eight-slice computed tomography (CT) scanner in an emergency room can significantly increase the number of stroke victims who receive a potentially life-saving treatment.

Patient photos help counteract anonymity common in radiologic exams

Including a patient's photo with imaging exam results may enable a more meticulous reading from the radiologist interpreting the images, as well as a more personal and empathetic approach, according to a study presented at the annual meeting of the Radiological Society of North America (RSNA).

Molecular breast imaging technique shows greater sensitivity over mammography, ultrasound and MRI for difficult to diagnose breast cancer

Breast-Specific Gamma Imaging (BSGI) has been proven to be a highly sensitive imaging technique for the diagnosis of invasive lobular carcinoma (ILC), a difficult to diagnose breast cancer.

Virtual colonoscopy has potential to screen for colorectal cancer and osteoporosis at same time

New research reveals that computed tomography (CT) colonography, also known as virtual colonoscopy, has the potential to screen for two diseases at once-colorectal cancer and osteoporosis, both of which commonly affect adults over age 50.

Exercise helps blood flow in senior brains

Older adults who exercise regularly show increased cerebral blood flow and a greater number of small blood vessels in the brain, according to findings presented today at the annual meeting of the Radiological Society of North America (RSNA).

Advanced CT scans 100 percent accurate in checking for clogged arteries

In a development that researchers say is likely to quell concerns about the value of costly computed tomography (CT) scans to diagnose coronary artery blockages, an international team led by researchers at Johns Hopkins reports solid evidence that the newer, more powerful 64-CT scans can easily and correctly identify people with major blood vessel disease and is nearly as accurate as invasive coronary angiography.

Mammogram most effective 12 months after radiation

Breast cancer patients who receive breast-conserving therapy and radiation do not need a follow-up mammogram until 12 months after radiation, despite current guidelines that recommend follow-up mammograms at between six and 12 months after radiation, according to a November 15 study in the International Journal of Radiation Oncology*Biology*Physics, the official journal of the American Society for Therapeutic Radiology and Oncology.

Type of breast reconstruction procedure impacts radiation therapy outcomes

For breast cancer patients who underwent a mastectomy who undergo radiation therapy after immediate breast reconstruction, autologous tissue reconstruction provides fewer long-term complications and better cosmetic results than tissue expander and implant reconstruction, according to a study in the November issue of the International Journal of Radiation Oncology*Biology*Physics, the official journal of the American Society for Therapeutic Radiology and Oncology.
