Norwegian study finds mixed success with electronic reports

Streamlining the process of delivering radiology reports -- and making them universally accessible -- doesn't guarantee that they'll be read any faster by clinicians. In fact, quite the opposite may occur if human behavior doesn't adapt to the changes imposed by adopting healthcare informatics.

NetMeeting software aids oncologist/radiologist collaboration

U.K. researchers have found that off-the-shelf Internet conferencing software can help improve collaboration between radiologists and radiation oncologists in ways that sophisticated PACS software can't.

Time doesn't diminish risk of cancer relapse after lumpectomy and RT

The risk of developing cancer again in the same breast after breast-conservation surgery and radiation therapy does not diminish over time, a long-term study of more than 1,000 women with stage I and stage II breast cancer has revealed.

Smoking during radiation therapy reduces treatment benefit

Patients with non-small cell lung cancer who smoke during the weeks they receive radiation therapy may reduce their overall benefit of treatment. Smoking has a significant negative effect as measured by several factors for assessing radiation therapy's effectiveness, according to study results.

Global radiation dose higher than necessary

Initial results of a multinational research study on x-ray quality control and patient dose conducted by the International Atomic Energy Agency (IAEA) reveal that up to 50% of x-ray exams performed in less developed nations are of substandard quality. What's more, many patients in these countries are being exposed to unnecessary radiation doses due to the need to repeat procedures.

Breast MRI with USPIO contrast helps assess lymph node metastases

Austrian researchers have found that breast MRI with a contrast medium based on ultrasmall superparamagnetic iron oxide (USPIO) particles could help avoid mastectomy for women whose breast cancer has not spread to the lymph nodes. But further development of the technique could be limited by the investigational nature of the contrast agent.

MRI beats mammography, US in detecting breast cancer in high-risk women

VIENNA - Breast MRI should be an integral part of annual breast cancer surveillance for high-risk women, according to researchers from Vienna. They compared mammography, ultrasound, and MRI for breast cancer screening in this patient population, and presented their findings at the 2008 European Congress of Radiology (ECR).
