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.

Misunderstandings real cost barrier to mammography

Women often cite cost as one reason they don't get regular mammography check-ups, but a new study finds they often misunderstand or simply aren't aware of benefits in their insurance plans that might help offset any financial burden.

Japanese women have lower recurrence of breast cancer

Early-stage breast cancer patients of Japanese descent that are treated with a lumpectomy and radiation therapy are more likely to be cured of their cancer than women of other ancestries, according to a new study published in the May 2005 issue of the International Journal of Radiation Oncology-Biology-Physics, the official journal of ASTRO, the American Society for Therapeutic Radiology and Oncology.

Black cohosh may interfere with breast cancer drugs

Black cohosh, an herb widely used by breast cancer patients to alleviate hot flashes and other menopausal symptoms, may alter the way that cells respond to drugs commonly used to treat breast cancer, according to a Yale School of Medicine study in Breast Cancer Research and Treatment.

Breast cancer screening situation will get worse

According to a recently published study, community-based mammography facilities do not have enough radiologists and certified technologists to adequately deliver screening and diagnostic services to the public, and the situation will probably get worse.

FDA hearings on silicone breast implants

On April 11-13, the FDA's advisory panel on General and Plastic Surgery Devices will once again meet to review data on the safety of silicone breast implants. The panel will vote Tuesday on Inamed Corporation's application for approval, and on Wednesday on Mentor Corporation's application.

Newer imaging technologies may lead to over treatment

Newer imaging technologies allow physicians to visualize more of the arteries in the lungs, including detecting small blood clots not previously seen, but seeing more may have little impact on the patient’s outcome, a new study suggests.

Chemoembolization, first-line treatment for liver cancer

New research by Jeff Geschwind, M.D., director of interventional radiology and associate professor at Johns Hopkins University School of Medicine, has shown that liver cancer patients, most of whom have inoperable tumours, could benefit from chemoembolization, a nonsurgical treatment option that delivers a high-dose of chemotherapy to the tumour while decreasing blood flow through the arteries feeding the tumour, known as embolization.

Endovenous laser ablation is a safe and highly effective treatment for a common cause of varicose veins

Endovenous laser ablation is a safe and highly effective treatment for a common but under-recognized cause of varicose veins -- reflux in a variety of veins collectively referred to as non-great saphenous veins -- according to results of a study presented today at the 30th Annual Scientific Meeting of the Society of Interventional Radiology.

Study shows connection of varicose veins to chronic pelvic pain

Research presented today at the Society of Interventional Radiology's 30th Annual Scientific Meeting found that 16 percent of women with varicose veins in their legs simultaneously had ovarian varicose veins -- a common but often under-diagnosed cause of chronic pelvic pain.

Hormonal treatment improves survival in high-risk prostate cancer patients

Administering hormonal treatment in addition to radiation therapy in patients with high-risk prostate cancer can improve survival rate, according to a new study published in the April 1, 2005, issue of the International Journal of Radiation Oncology-Biology-Physics, the official journal of ASTRO, the American Society for Therapeutic Radiology and Oncology.

Benefits of lung cancer screening with CT questioned

Annual screening with helical computed tomography (CT) can help radiologists detect lung cancers at their earliest, most curable stage, but has not been shown to reduce mortality from the disease, according to a study published in the April issue of the journal Radiology.
