The powerful X-ray tubes of our SOMATOM CT portfolio provide enough mA reserves to allow low kV scanning in clinical routine, optimizing the profile of the X-ray spectrum to help reduce radiation and iodine dose.

Lower kV settings help reduce radiation dose and the amount of contrast media needed in coronary CTA.
In this case, a coronary CT angiography (cCTA) shows a moderate stenosis in the proximal left anterior descending artery (LAD) caused by a calcified plaque. Image data was acquired on a SOMATOM go.Top CT scanner at 80 kV to enhance the contrast-to-noise ratio, resulting in a reduction in the radiation dose as well as in the amount of contrast agent needed (28 ml).
The statements by Siemens Healthineers’ customers described herein are based on results that were achieved in the customer's unique setting. Because there is no “typical” hospital or laboratory and many variables exist (e.g., hospital size, samples mix, case mix, level of IT and/or automation adoption) there can be no guarantee that other customers will achieve the same results.
