Used properly, CT scanning is an excellent diagnostic instrument; the benefits of its use outweigh the risks. But CT can be detrimental to health when used inappropriately—eg, for self-referred reassurance scans. So concludes a report published in 2007 by the UK Committee on Medical Aspects of Radiation in the Environment (COMARE). All nine of the recommendations were accepted by the UK Department of Health on April 6, 2010. The committee reviewed the published work on benefits and risks associated with CT scanning in the health assessment of symptom-free individuals. They defined self-referred CT scans as an “individual health assessment”. However, COMARE will not ban or prohibit scans but bring them within a formal regulatory regimen and distinguish them from diagnostic scans. The government legislation that will be amended is the Ionising Radiation (Medical Exposure) Regulations 2000 (IR(ME)R).

The use of medical imaging procedures has been increasing, and this study estimated the exposure of U.S. patients to low-dose ionizing radiation from these procedures. The exposure was substantial, largely because of radiation from computed tomography and nuclear imaging. The highest average effective dose was attributable to myocardial perfusion imaging, and most imaging occurred in outpatient settings. These data indicate that the use of imaging can result in high radiation doses.

Some transdermal patches contain metal and may cause burns to the skin if patients wear them during magnetic resonance imaging (MRI), according to a public health advisory from the US Food and Drug Administration (FDA).

One of the most amazing advances in the clinical treatment and management of disease is the ability to detect so many things preoperatively using imaging technologies such as 3-dimensional computed tomography, magnetic resonance imaging, or positron emission tomography.

For women facing radiation therapy after surgery for breast cancer, the standard course of treatment typically involves daily radiation sessions over a period of 6 to 7 weeks. That regimen can be hard to manage, especially for women already juggling work and child care schedules or for those living far from treatment centers.

The use of CT is more and more frequent, both for better and better definitions, and for costs which are gradually knocked down and the use of this diagnostic technique is increasing also in the pediatric population.
