Due to the wide availability, rapid availability and relatively low cost of computed tomography (CT), CT testing is becoming more and more common

Different technical solutions, such as tube current modulation (TCM) and tube voltage adaptation (TVA), have been developed and introduced into clinical practice to minimize radiation exposure to patients

Recently, a study published in the journal European Radiology evaluated the quality of inter-individual images between dose-matched dual-energy WAI reconstructions and automatically selected head and neck low-tube voltage single-energy CT images, achieving a low dose radiation burden

Eight0 patients were randomized on a dual-source CT scanner with EITH(n = 40, reference mAs 200) or radiation dose-matched DECT scans (n = 40,80/Sn150 kV, reference mAs A tube 91/B tube 61).

The effective radiation dose (ED) between SECT and DECT study groups was comparable (2.

This study shows that DECT with ready-to-use WAI provides excellent image quality and is very beneficial for head and neck imaging
