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.

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.

Functional magnetic resonance imaging better than polygraph to find liars

Traditional polygraph tests to determine whether someone is lying may take a back seat to functional magnetic resonance imaging (fMRI), according to a study appearing in the February issue of Radiology.

Radiologists more accurately identify damage to knee cartilage by using four radiologic 'signs'

Using the four signs to identify the extent and type of damage to knee cartilage makes interpreting MRIs with higher degrees of accuracy easier for any radiologist, regardless of their level of expertise.

Unexpected rheumatoid arthritis discovery

What makes joints in people with rheumatoid arthritis, and related conditions like Lyme disease or lupus, so susceptible to attack by the body's immune system, leading to painful flare-ups and deterioration? The answer may surprise you.

Even asymptomatic former smokers should consider CT screening

Smokers and former smokers should be screened for lung cancer even if they don't have symptoms, according to a new study led by physician-scientists at NewYork-Presbyterian Hospital/Weill Cornell Medical Center.

Simple diagnostic imaging procedure changes treatment for lower back pain

A simple diagnostic imaging procedure can help identify patients with lower back pain who would benefit from spinal injections and spare those who would not, according to a study appearing in the February issue of Radiology.

Tetracaine mouthwash helps with pain linked to head and neck cancer

Doctors in Italy are studying whether a new type of mouthwash will help alleviate pain for patients suffering from head and neck cancer who were treated with radiation therapy, according to a study published in the International Journal of Radiation Oncology-Biology-Physics

13 Feb 2006

PET imaging has the potential to improve cancer care management

A limitation of current cancer care is the difficulty of quickly assessing how well a therapy is working. However, expanding the use of existing positron emission tomography (PET) technology can provide early and accurate assessment of a tumor's response to a particular therapy allowing physicians to better tailor a patient's treatment

Diabetic heart muscle makes heart disease the most common killer of diabetics

The high-fat "diet" that diabetic heart muscle consumes helps make cardiovascular disease the most common killer of diabetic patients, according to a study done at Washington University School of Medicine in St. Louis.
