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.

Radiofrequency ablation (RFA) is an effective, longlasting treatment for small kidney tumors in selected patients

Massachusetts General Hospital (MGH) researchers have shown that radiofrequency ablation (RFA) - a minimally invasive way of destroying tissue - is an effective, longlasting treatment for small kidney tumors in selected patients.

Arterial spin labeling distinguishes between Alzheimer's disease and frontotemporal dementia

A non-invasive magnetic resonance imaging (MRI) technique called arterial spin labeling is just as accurate as invasive scanning techniques in distinguishing Alzheimer's disease from frontotemporal dementia (FTD) in the brains of elderly people, according to a new study at the San Francisco VA Medical Center (SFVAMC).

MRI measurement of breast tumor volume predicts whether a patient's cancer will return

The study, performed at the University of California-San Francisco, of 58 breast cancer patients found that the best way to predict a patient's recurrence-free survival is to review the initial MR examination (before the patient has chemotherapy) and the final MR examination (after chemotherapy has been completed).

Aortic disease difficult to diagnose

Aortic disease kills nearly 15,000 people in the United States each year, but the rarity and complexity of this deadly disorder make accurately diagnosing it difficult for doctors in the health-care trenches, University of Florida researchers have found.

Digital mammography no better than traditional film X-rays in the ability to detect cases of breast cancer

Digital mammography provides no clear-cut improvements over traditional film X-rays in the ability to detect cases of breast cancer, says a new technology assessment report. The technology does, however, offer other benefits, including slightly lower radiation doses for patients, that may prompt its increasing use despite its much higher costs.

Revolutionising medical imaging internationally

A team of RMIT University researchers has developed cutting-edge technology that has the potential to revolutionise medical imaging internationally.

Researchers successfully image delivery and gene expression of DNA nanoparticles into lungs of CF mice

Researchers at the American Society of Gene Therapy Meeting in St. Louis announced that by using imaging technologies, they are able to successfully trace the delivery of DNA nanoparticles and the extent of gene transfer in the lungs of cystic fibrosis (CF) animals.

Whole-body positron emission tomography/computed tomography scans may help physicians identify malignant cancerous tumors

A team of researchers at Johns Hopkins Medical Institutions in Baltimore, Md., reports that whole-body positron emission tomography/computed tomography (PET/CT) scans may help physicians identify new, unexpected malignant cancerous tumors in patients, according to an article in the May issue of the Society of Nuclear Medicine’s Journal of Nuclear Medicine.

Practice of defensive medicine widespread among physicians in specialties at high risk of lawsuits

More than 90 percent of surveyed physicians in Pennsylvania reported defensive medicine practices such as over-ordering of diagnostic tests, unnecessary referrals and avoidance of high-risk patients, according to a study in the June 1 issue of JAMA.

Medical imaging costs at a steady percentage of overall hospital costs

The substantial increase in the use of medical imaging during recent years has fueled speculation that imaging costs were a major factor behind the rise in overall health care costs.

Ultrasound-guided percutaneous biopsies are a safe and effective alternative to endoscopic biopsies

In most cases (61%) a diagnosis was possible after two passes with the biopsy needle. There were no major complications. In 14 of the patients, malignancy was diagnosed; eight patients had benign results.

Chest CT can be first step to identifying if patient has had a heart attack

When radiologists are looking at contrast-enhanced chest CT examinations, they should take a look at the patient's heart to rule out heart attack, regardless of why the chest CT examination is being performed, a new study shows.

New kidney test better elder mortality predictor

A study at the San Francisco VA Medical Center (SFVAMC) has found that a test of kidney function that measures blood levels of cystatin C -- a protein produced by most cells in the body -- is a far more accurate predictor of mortality risk in elderly people than the current standard kidney function test, which measures levels of the protein creatinine.

Radioimmunotherapy streamlines non-Hodgkin's lymphoma treatment

Researchers at the Keck School of Medicine of the University of Southern California and colleagues have found a way to streamline a new form of treatment for patients with non-Hodgkin's lymphoma.

Routinely reformatting computed tomography (CT) scans to view organs from several different directions may help radiologists improve diagnosis

"You can see things in one view that you might miss in another," said Craig Barnes, M.D., section head of pediatric radiology at Wake Forest Baptist's Brenner Children's Hospital. "It costs no more as relates to scan time or radiation exposure, and we believe it provides added value in diagnosis."

Over-the-phone transmission of diagnostic-quality ultrasound images is possible

Over-the-phone transmission of diagnostic-quality ultrasound images is possible, potentially paving the way for ultrasound examinations to be performed in poorer areas of the world, inexpensively transmitted via the Internet, and read by experienced radiologists elsewhere, a new study shows.

Combined MRI and mammography more effective at detecting breast cancer in high risk women

Annual screening, using magnetic resonance imaging (MRI) and X-ray mammography, is the best way to detect breast cancer in women that have a high genetic risk of the disease, according to a study published online by The Lancet.

16 May 2005

Significant non-coronary findings found during heart CT scans point to importance of trained radiologists

A significant percentage of patients undergoing targeted CT of the heart have abnormalities outside the coronary arteries, some of which could be life threatening, and as a result need the experience of trained radiologists to interpret them, say researchers from the University of Michigan Cardiovascular Center in Ann Arbor.

Less invasive procedure for treatment of uterine fibroids is effective

Women who suffer from the frustrating and painful chronic symptoms of uterine fibroids have a safe and effective alternative to surgery according to new five-year studies presented at an annual meeting of the Society of Interventional Radiology held in April. Studies found that uterine fibroid embolization has a 73 percent success rate at five years.

Breast CT may improve on mammography - more gentler, more accurate

A new breast screening technology that may be able to detect tumors earlier than mammography -- without the need for uncomfortable breast compression -- is being tested in patients at the University of California, Davis, Medical Center.
