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.

Prostatic artery embolization comparable to transurethral resection

A new interventional radiology treatment that blocks blood supply to men's enlarged prostate glands shows comparable clinical results to transurethral resection of the prostate (or TURP), considered the gold standard (or most common) treatment. However, this minimally invasive treatment-prostatic artery embolization-has none of the risks associated with TURP, such as sexual dysfunction, urinary incontinence, blood loss and retrograde ejaculation, noted researchers at the Society of Interventional Radiology's 36th Annual Scientific Meeting in Chicago.

Backscatter airport scanners may not increase lifetime risk of cancer in travelers

Calculations by researchers at the University of California, San Francisco and the University of California, Berkeley estimate that the cancer risk associated with one type of airport security scanners is low based on the amount of radiation these devices emit, as long as they are operated and function correctly.
