Are full-body CT scans truly capable to do that – and what are the risks? And are DEXA scans a very good way to test on your overall body composition?

Though systems change, most of these higher-tech checkups use computed tomography (CT) scans to take a look at your whole body or distinct pieces, this kind of as the heart and lungs, to try to capture hazardous ailments in before, extra curable stages.

In the course of the 15- or 20-moment scan, you lie inside a doughnut-shaped device as an imaging device rotates close to you, transmitting radiation. The technique combines various X-ray visuals and, with the aid of a laptop or computer, provides cross-sectional sights of your body.

Advocates encourage scans as a clever section of a routine physical exam. But if you are wholesome, with no worrisome signs, a scan is typically not warranted, states Arl Van Moore, MD, a radiologist and medical assistant professor of radiology at Duke College Health care Heart in Durham, NC, who is also a spokesman for the American School of Radiology (ACR).

According to the ACR’s formal placement, there is not plenty of evidence to recommend scans for individuals with no indicators or family history suggesting disorder. But Van Moore sees a attainable exception. “There might be a advantage to persons at high chance of lung cancers, these types of as present-day smokers or people with a extended heritage of smoking,” he claims. 

For healthier people, the scans may well result in undue get worried – for occasion, by discovering anything that turns out to be benign.

If scans are completed way too usually, the radiation publicity may well basically enhance the amount of cancer cases above the very long expression, in accordance to a 2004 report in the journal Radiology.

The American University of Preventive Medicine states that full-body scans “aren’t very good at locating cancer in folks without having symptoms” and that the radiation you get from these scans can improve your risk of most cancers.

Ahead of scheduling a entire body scan, talk to your health care provider about your in general overall health threats and how a scan may or could not assistance you. In unique, request on your own:

This is a various kind of scan, identified as DEXA (dual strength X-ray absorptiometry). You might have listened to of DEXA scans to look at on bone density to see if you have osteoporosis or osteopenia. It works by using reduced-level X-rays to check out on your entire body composition, like how a lot entire body extra fat you have and where by it is in your body. 

There are several ways to measure your overall body extra fat. Professionals have told WebMD in the earlier that DEXA scanning is a “very very good technique” and “one of the most precise techniques out there.” And researchers have referred to as it the “gold standard” for examining on entire body composition – especially, for bone, body fat, and muscle mass.
