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 shows drugs work differently in the brains of men and women

A Johns Hopkins discovery could lead to tailored treatments for drug abuse and neurological diseases after providing what is believed to be the first evidence in people that amphetamines have a greater effect on men's brains than women's.

Magnetic nanotechnology holds promise in fighting cancer

Detecting cancer and reinventing computing are two challenges that seemingly have little, if anything, to do with each other. That is, unless you are a nanotechnologist like Shan Wang, an associate professor of materials science and engineering and of electrical engineering at Stanford.

Significant differences in the patterns of mammography by race and ethnicity

Inadequate use of screening mammography may be an important reason that African-American women are more likely to be diagnosed with advanced stage breast cancer than members of other ethnic groups, according to a new study led by a University of California, San Francisco imaging specialist.

Imaging of breast cancer diagnosed and treated with chemotherapy during pregnancy

Ultrasound provides a safe and accurate method of detecting breast cancers in pregnant women, as well as assessing response to chemotherapy, according to a study appearing in the April issue of Radiology.

First study of uterine fibroid embolization to treat post-menopausal women

The first study of uterine fibroid embolization to treat post-menopausal women shows that the non-surgical treatment was technically successful in 100 percent of patients, and improved bulk-related symptoms in 92 percent of the women.

Radiofrequency ablation is as effective as surgery for small liver tumors

Three-year data shows that radiofrequency ablation is as effective as surgical resection for overall survival and tumor recurrence, for the treatment of single small hepatocellular carcinoma in patients with liver cirrhosis, according to a study presented at the Society of Interventional Radiology's 31st Annual Scientific Meeting.

Enzymes that harm brain immediately after stroke may be beneficial days later

Insights from the study could change the way stroke is treated, extending the window for effective treatment from a couple of hours to a couple of weeks. The results may suggest new ideas for drug development.

Doctors able to predict recurrence of high-risk breast cancers

International researchers have developed a prediction model to assist doctors in determining the chance of recurrence of cancer in high-risk breast cancer patients who have undergone a mastectomy followed by radiation therapy.

Innovative automatic system stops patients falling through gaps

Every day in hospitals around the country, thousands of patients undergo CT, MRI, X-ray and other kinds of scans, producing detailed images of their bodies. Specially trained doctors "read" those images to look for problems, and then send a report of what they've found to each patient's own doctor.

Computerized tomography guided percutaneous renal cryoablation with the patient under conscious sedation

When an event occurs once, we have a tendency to look at it as a phenomenon, but when it occurs twice, it begins to enter the realm of accepted reality.

Rapamycin (sirolimus) may be effective in treating kidney disease

A widely available drug may be effective in treating kidney disease, report scientists at the University of California, Santa Barbara. They describe the discovery in the online edition of the Proceedings of the National Academies of Science.

Smoking interferes with the brain's ability to recover from the effects of chronic alcohol abuse

"This study suggests that for better brain recovery, it may be beneficial for alcoholics in early abstinence to stop smoking as well," concludes Dieter Meyerhoff, Dr.rer.nat., a radiology researcher at SFVAMC and the senior author of the study. Meyerhoff is also a professor of radiology at the University of California, San Francisco.

Low PSA score after radiation can predict prostate cancer return

A consortium of prostate cancer experts have discovered, through a clinical investigation, that prostate cancer patients who have a lower prostate specific antigen (PSA) score after radiation therapy to treat their cancer are less likely to have their prostate cancer return or spread to other parts of their body than patients with a higher PSA score.

Valproic acid may help slow the progression of dementia

Researchers have found that a common anticonvulsant drug improved cognitive function and appeared to restore nerve cells in the brains of patients with HIV-related dementia. The results of the Phase I clinical trial are published in the March issue of the scientific journal Neurology.

New method to increase the efficiency of contrast radiology

A new method to increase the efficiency of contrast radiology may open the way to earlier and more reliable diagnosis of, for example, breast cancer. With new integrated electronics and signal processing, the image quality can be improved sharply.

Extensive study of natalizumab

Scientists have completed an extensive study of more than 3,000 patients who received a promising anti-inflammatory drug, natalizumab, that was linked to three cases of a serious brain infection in large clinical trials halted in early 2005.

Amifostine makes radiation more effective

Doctors in Brazil have concluded that the drug amifostine eases many of the most common side effects associated with patients receiving radiation therapy to treat their cancer while simultaneously making the cancer more susceptible to radiation.

Magnetic resonance imaging can help rule out acute appendicitis in pregnancy

Magnetic resonance imaging (MRI) can help rule out acute appendicitis in pregnancy when ultrasound findings are inconclusive, according to a study in the March issue of Radiology.

Papillary lesions of the breast should be surgically excised to avoid missing a cancer

Certain breast lesions diagnosed as benign on core needle biopsy have cancer at surgical excision and thus should be removed, according to a study appearing in the March issue of Radiology.

New radiological approach for mass fatality investigation

As far as we know, for the first time in the world a new radiological system was used recently at a mass fatality investigation. A team of researchers led by Professor Guy Rutty of the University of Leicester Forensic Pathology Unit used a mobile MSCT scanner at the mortuary for the examination of the victims of a vehicle mass fatality incident.
