''PURPOSE: To determine the radiation dose to radiologists who perform computed tomographic (CT) fluoroscopic interventional procedures by using a quick-check method and a low-milliampere technique. MATERIALS AND METHODS: Two hundred twenty CT ...'

''Detectors that are presently used for mammograms and for dose measurements in radiotherapy are often rigid, causing errors in screening, or dose delivery to surrounding healthy tissue. This has raised concerns of additional tissue damage or the growth of ...'

''X-ray computed tomography (CT) is one of the diagnostic procedures that can cause relatively high radiation exposure to the patient. In the last two decades, the increasing use of CT in clinical practice and the relatively high doses delivered to the ...'

''A new cardiac CT technique, prospective gated 64-channel cardiac CT, has a significantly lower radiation dose and produces CT coronary angiograms with better image quality when compared with the standard retrospective ECG gating, according to a recent ...'

''Annual low-dose computed-tomography (CT) screening can eliminate the need for biopsy or surgery in nonsolid lung nodules, according to a new study published online in the journal Radiology. Nonsolid nodules (NSNs) are usually asymptomatic growths in the ...'
