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.

New portable and low-cost device will make quality control of radiotherapy treatments possible

The research team from the Department of Electronics and Computer Science at the University of Granada (UGR), together with the Department of Radiology at the Hospital Virgen de las Nieves in Granada, have designed a portable and low-cost device which can measure the ionizing radiation someone is exposed to, for example, during radiotherapy.

CT colonography used in elderly patients detects a high number of abnormalities outside the colon

CT colonography (CTC), when used in elderly patients, can detect a high number of new and significant abnormalities outside the colon (including cirrhosis and tumors) and is well tolerated, according to a recent study conducted by researchers at St. James's University Hospital in Leeds, United Kingdom (UK).

64-slice CT scans a good test for clogged arteries

A study by an international team of cardiac imaging specialists, led by researchers at Johns Hopkins, concludes that sophisticated computed tomography (CT) scans of the heart and its surrounding arteries are almost as reliable and accurate as more invasive procedures to check for blockages.

Older adults no more distractible than younger adults

Despite previous research suggesting that older adults are more distractible, new research shows they are no more distractible than younger adults when asked to focus their attention on their sense of sight or sound, or when asked to switch their attention from one sense to the other.

Radiation seed implant decreases risk of death over watchful waiting/active surveillance for prostate cancer

Prostate cancer patients cut their risk of dying of the disease in half when they receive radiation seed implants (brachytherapy) to treat their cancer, compared to those who don't receive active treatment (watchful waiting/active surveillance), within six months from being diagnosed with localized prostate cancer, according to a study presented October 31, 2007, at the American Society for Therapeutic Radiology and Oncology's 49th Annual Meeting in Los Angeles.

Radiation after surgery keeps high-risk prostate cancer at bay

An analysis of data involving more than 2,000 patients from 17 U.S. institutions demonstrates that men with high-risk prostate cancer who receive radiation therapy after a prostatectomy were less likely to have a recurrence of disease.

Stereotactic radiation is effective as surgery against nerve tumor

Specifically aimed, "stereotactic" radiation may be as good as surgery - and in some cases, even better - in treating benign but potentially devastating brain tumors called non-acoustic schwannomas, according to a study by rradiation oncologists at the Kimmel Cancer Center at Thomas Jefferson University and Thomas Jefferson University Hospital in Philadelphia.

Children would need different medical care in wake of dirty bomb

If terrorists were to attack with a dirty bomb, medical authorities should be prepared to treat children differently than adults because their developing bodies would absorb and respond to the radiation exposure in distinct ways, according to a new study from the University of Rochester Medical Center.

Which lung volumes to use for radiotherapy planning of lung cancer

A new method to standardize the reporting of radiation dose volumes in the use of four-dimensional computed tomography (4D-CT) can lead to a more accurate radiation dose to the lungs in lung cancers, thereby lowering the risk of lung injury, according to a study presented at the Plenary I session on October 29, 2007, at the American Society for Therapeutic Radiology and Oncology's 49th Annual Meeting in Los Angeles.
