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.

PET imaging of cerebral cannabinoid CB1 receptors with [11C]JHU75528

A team of Johns Hopkins researchers developed a new radiotracer - a radioactive substance that can be traced in the body - to visualize and quantify the brain's cannabinoid receptors by positron emission tomography (PET).

Helium-based MRI scans may one day allow closer look at smoker lungs

Aided by a powerful imaging technique, scientists have discovered they can detect smoking-related lung damage in healthy smokers who otherwise display none of the telltale signs of tobacco use.

Breast radiation device associated with complications

Doctors in New England have discovered that patients receiving accelerated-partial breast radiation therapy using a balloon brachytherapy system after lumpectomy for breast cancer can develop seroma, the retaining of fluid, in their breast which can require aspiration or make monitoring them by physical exam more difficult.

Health disparities in juvenile rheumatoid arthritis

Juvenile rheumatoid arthritis (JRA), a group of autoimmune diseases involving chronic inflammation of the joints, can adversely affect health-related quality of life, often into adulthood.

Breast removal not the only treatment option for non-invasive breast cancer

Breast conserving surgery, long known to be successful at treating the more common invasive cancer, can also be effective for this pre-invasive condition, according to a new study from researchers at the University of Michigan Comprehensive Cancer Center.

New procedure to treat fractured vertebrae caused by spinal tumors

A radiologist at the University of California, San Diego (UCSD) School of Medicine has developed a new procedure to treat fractured vertebrae caused by spinal tumors, a procedure that may decrease the risk of complications, which are experienced by 5 to 10% of patients with malignant tumors of the spine.

Breast conserving surgery is a good option for early breast cancer

For women diagnosed with a type of non-invasive breast cancer, removing the breast is not the only treatment option.

Low radiation dose still means successful interventional procedures

Radiation dose can be reduced by as much as 88 percent for common interventional radiology procedures and still be safe and effective, a new study shows.

New radiation protection technique significantly reduces physician radiation exposure during coronary angiography

Using the new device, physicians monitor patients' angiograms and control exam table movement from behind a lead plastic shield. A newly developed extension bar allows the physician to remain safely behind the shield and still retain table control for panning, according to Martin Magram, MD, developer of the new technique and assistant professor in the department of diagnostic radiology.

Ultrasound-guided, intra-tendonous injection of a dextrose solution effective in treating chronic tendonoses in the leg

Ultrasound-guided, intra-tendonous injection of a dextrose solution is a very effective treatment for certain chronic tendonoses in the leg, reported radiologists from the department of radiology at St. Paul's Hospital and the Department of Family Practice at the University of British Columbia both in Vancouver, BC.

Initial experience of FDG-PET/CT guided IMRT of head and neck carcinoma

Doctors have discovered that combining images derived from positron emission tomography and computed tomography in the planning and delivery of radiation treatment for patients with head and neck cancer leads to more accurate delivery of the radiation dose and an increased chance for survival.

Early myocardial enhancement defects (dark spots) on multidetector CT are valuable predictors of myocardial viability

...in patients who have suffered a heart attack, reported doctors from the departments of cardiology and radiology at Rambam Medical Center in Haifa, Israel.

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.
