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.

Study finds rise in rate of diagnostic imaging in managed care

Use of radiology imaging tests has soared in the past decade with a significant increase in newer technologies, according to a new study that is the first to track imaging patterns in a managed care setting over a substantial time period.

Cancer risk from cardiac CT overstated

Radiology and cardiovascular researchers from the Medical University of South Carolina in Charleston, S.C., today presented 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.

MRI helps predict multiple sclerosis progression

A new study published in Journal of Neuroimaging shows that MRI scans used on multiple sclerosis (MS) patients to determine if the disease has affected gray matter in the brain can identify those at-risk for progression of disability.

Cone-beam CT compared to MDCT before and after percutaneous vertebroplasty

Cone-beam CT which is believed to deliver less radiation than MDCT is just as useful when evaluating patients before and after percutaneous vertebroplasty according to a study performed at the Department of Clinical Radiology, Kyushu University, Fukoka, Japan.

New imaging technique detects early cervical cancer

The Institute of Cancer Research and The Royal Marsden Hospital have developed a new imaging technique which locates previously undetectable early stage cervical cancers, according to research published in Radiology today (October 21).

New way to control protein activity could lead to cancer therapies

Investigators at the Stanford University School of Medicine have found a way to quickly and reversibly fine-tune the activity of individual proteins in cells and living mammals, providing a powerful new laboratory tool for identifying - more precisely than ever before - the functions of different proteins.

Protecting patient privacy the new fashioned way

Protecting patient privacy has been recognized as the duty of health-care providers for aHealth Insurance Portability and Accountability Actbout as long as doctors have seen patients. Since 1996, that duty became a legal obligation when Congress passed the Health Insurance Portability and Accountability Act.

Some cases of breast cancer overtreated

According to a new study standard radiation therapy for some breast cancer patients may not be medically required and may, therefore, be causing unnecessary serious side effects.

One week radiation treatment for breast cancer as effective as standard 6 to 7 week course

A new type of radiation treatment rapidly speeds up treatment for some breast cancer sufferers.

Breast MRI scan could determine need for radiation therapy

For women whose breast cancer has spread to their lymph nodes, a magnetic resonance imaging (MRI) scan could replace exploratory surgery as the method for determining whether those women need radiation therapy to treat their disease, according to a study to be presented during the annual meeting of the American Society for Therapeutic Radiology and Oncology (ASTRO) which opens today in Boston.

New tool for early diagnosis of breast cancer

Scientists from Finland, Germany and the ESRF have developed a new X-ray technique for the early detection of breast cancer. This allows a 3D visualization of the breast with a high spatial resolution and is extremely sensitive to alterations in the tissue, such as those generated by cancer. This technique could be used in the next years in hospitals. It may help doctors to detect tumours with greater precision than is possible using current X-ray mammography.

Benefits of combined treatments against cancer

In cancer therapy, the best results are often achieved by combining treatments such as chemotherapy, radiotherapy and surgery. This multidisciplinary approach is the focus of special symposia at the meetings of the European Society for Medical Oncology (ESMO) and the European Society for Therapeutic Radiology (ESTRO) taking place in Sweden this month.

Pain-relieving gel makes mammograms a less painful experience

Women dreading the prospect of another painful mammogram can, according to researchers, relieve some of the breast discomfort by using a pain-relieving gel.

World's first hand-held ultrasound imaging device

Siemens Canada Limited has partnered with Vancouver General Hospital (VGH) to implement the new ACUSON P10 ultrasound system - the world's first hand-held ultrasound imaging device - replacing the existing technology.

Brachytherapy may benefit obese prostate cancer patients

Brachytherapy, also called seed implants, may be a more beneficial treatment than surgery or external beam radiation therapy for overweight or obese prostate cancer patients, according to a study published in the August issue of the International Journal of Radiation Oncology-Biology-Physics, the official journal of the American Society for Therapeutic Radiology and Oncology.

Ultrasound imaging predicts heart attack risk

Repeat exams using widely available and inexpensive ultrasound imaging could help identify patients at high risk for a heart attack or other adverse cardiovascular events, according to a study published in the September issue of the journal Radiology.

The Kenneth B. Schwartz Center, ASTRO partner to raise awareness of cancer survivorship

As part of its continued effort to give back to the cancer communities in the cities visited during its annual scientific meeting, the Fairfax, Va.-based American Society for Therapeutic Radiology and Oncology (ASTRO) is partnering with the Kenneth B. Schwartz Center to raise awareness of cancer survivorship. The Kenneth B. Schwartz Center conducts pioneering programs to educate, train and support caregivers in the art of compassionate healthcare.

Amyloid plaques seen with conventional MRI in animal model for first time

For the first time, scientists have captured images of brain lesions similar to those found in Alzheimer's disease using clinical-grade MRI in an animal model of the disease, according to research reported at the Alzheimer's Association's 2008 International Conference on Alzheimer's Disease (ICAD 2008), in Chicago.

Knowing means simplifying: gluten-free diet alone is enough to cure the bones of pediatric patients with celiac disease

Individuals affected by celiac disease (gluten intolerance) often present an altered calcium (Ca2+) metabolism that can cause osteopenia, a bone mass decrease due to the impaired adsorption of this mineral, which can lead to osteoporosis (in 35-85% of the cases).

Endurance exercise makes heart younger

Absence may make the heart grow fonder, but endurance exercise seems to make it younger. According to a study conducted at Washington University School of Medicine in St. Louis, older people who did endurance exercise training for about a year ended up with metabolically much younger hearts.
