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.

Optical coherence tomography (OCT) can successfully identify the characteristics of coronary plaques

A catheter-based imaging technology called optical coherence tomography (OCT) can successfully identify the characteristics of coronary plaques in patients with various cardiac symptoms. The report from researchers at Massachusetts General Hospital (MGH) will appear in the journal Circulation.

Diffusion MRI gives early indication if brain cancer therapy is effective

A special type of MRI scan that measures the flow of water molecules through the brain can help doctors determine early in the course of brain cancer regimen if a patient's tumor will shrink, a new study shows.

Benefits of lung cancer screening with CT questioned

Annual screening with helical computed tomography (CT) can help radiologists detect lung cancers at their earliest, most curable stage, but has not been shown to reduce mortality from the disease, according to a study published in the April issue of the journal Radiology.

First patient to test new treatment for peripheral arterial disease

For several years, crippling leg pain has prevented Joan Erickson from walking more than a block. If she paused to rest, she could walk a little more, but not enough to continue playing golf, her favorite pastime.

Combining PET and CT scans leads to more accurate radiation therapy for lung cancer patients

Using Positron Emission Tomography in addition to Computed Tomography can reduce the amount of radiation exposure to normal tissue in some lung cancer patients

Prostate screenings could be used to encourage colon checks

Colon cancer is the third leading cause of cancer death in men, but according to a new University of Michigan Health System study, fewer than half of men surveyed were up-to-date with colon cancer screenings.

MRI better than current standard of practice in assessing neoadjuvant chemotherapy in breast cancer patients

More breast cancer patients with large palpable tumors are now undergoing chemotherapy before surgery in an effort to reduce the size of their tumor, and MRI is the best way to predict if the chemotherapy is working, preliminary results of a study show. If the chemotherapy is successful, then the woman may be able to undergo breast-conservation surgery rather than a mastectomy.

More experienced physicians less likely to falsely characterize a mammogram as abnormal

Physicians who specialize in screening mammography and who have at least 25 years of experience are more accurate at interpreting the images and subject fewer women to the anxiety of false positives for cancer, when compared to physicians with less experience or those who don't have the same focus, according to a new study.

Scientists re-produce the human body's own cancer-killing cells through gene therapy

New hope to cancer sufferers comes from research by South Korean scientists who have found a way to re- produce the human body's own cancer-killing cells through gene therapy.

Mammography comfort aid yields better detection

A mammography aid designed to improve patient comfort, used together with additional training for radiology technologists, improves breast positioning and yields better image results for women and their doctors, according to a study conducted at St. John Hospital and Medical Center, Detroit, MI.

Measuring hyaluronan in joints and fluid that lubricates cartilage might enable doctors to diagnose osteoarthritis more accurately

Measuring a biological chemical called hyaluronan found naturally in joints and the fluid that lubricates cartilage might enable doctors to diagnose osteoarthritis of the knee and hip earlier or more accurately, a new study concludes.

$Women who need treatment for osteoporosis may not be receiving it because their history of fractures not being considered$

Women who need treatment for osteoporosis may not be receiving it because their history of fractures not being considered

Previous fractures indicate that bones are weaker than normal, but the information isn't being taken into account when treating for osteoporosis, said Dr. Kerry Siminoski, professor of radiology and diagnostic imaging at the University of Alberta.

Nonsurgical microspheres an option for liver cancer patients

A study in February’s Journal of Vascular and Interventional Radiology found that patients undergoing liver cancer treatment with Theraspheres?, radioactive microspheres containing Yittrium-90, can tolerate a 150 Gy single dose or 268 Gy repeated dose without risk of radiation-induced liver disease.

Clot-dissolving drugs such as tPA may help detect potentially deadly leg clots

A possible diagnostic use for clot-dissolving drugs such as tPA has been found by Medical College of Georgia researchers working to improve a test that identifies potentially deadly blood clots in the legs.

New brochure helps explain treatment for gynecologic cancers

The American Society for Therapeutic Radiology and Oncology has published a new patient information brochure Radiation Therapy for Gynecologic Cancers: Facts to Help People Understand Their Treatment Options to help educate patients and their families about the treatments available for gynecologic cancers.

Special imaging study shows failing hearts are energy starved

Using magnetic resonance spectroscopy (MRS) for the first time to examine energy production biochemistry in a beating human heart, Johns Hopkins researchers have found substantial energy deficits in failing hearts.

VCU Gastroenterology research papers ranked 4th in most cited papers

Virginia Commonwealth University’s School of Medicine has been ranked fourth among federally funded U.S. universities based on the average number of citations per research paper published in indexed journals of gastroenterology and hepatology between 1999 and 2003.

Whole-body computed tomography (CT) is not a cost-effective screening method

The use of whole-body CT as a screening tool for cancer and other diseases is the focus of an ongoing debate. Proponents of whole-body CT emphasize the potential benefit of early detection of disease, but others caution that the costs, false-positive findings and unnecessary radiation might render the procedure more harmful than beneficial.
