dual-energy CT has been applied in many clinical areas, including automatic bone removal, stone composition characterization, virtual non-contrast imaging, diagnosis of gout, and assessment of myocardial blood supply. All these clinical applications require dual-energy processing to obtain material-speciﬁ c information.1,2 Dual-Source Dual-Energy CT • A SOMATOM Defi nition dual source CT scanner (Siemens Healthcare, Forchheim, Germany) was used to acquire images on all patients.

昨今の流行でもあるDual Energy CT。 Dual Energyと略して呼ぶことが多いですが、ここではDECTと略します。 CTに関する学会の演題も、大半が逐次近似再構成法の話かDECTの話、と言っても過言ではないでしょう。今回は、そのDECTについて基礎的な部分を解説します。

In a DECT scan, projections are acquired at 140 kV (orange solid line) and 80 kV (green dashed like) alternatively at every 0.2 milliseconds. By contrast, projections are acquired at 140 kV (or lower kV) only throughout the entire SECT scan (Reprinted with permission from JACC Cardiovascular Imaging) Dual energy CT, also known as spectral CT, is a computed tomography technique that uses two separate x-ray photon energy spectra, allowing the interrogation of materials that have different attenuation properties at different energies. The dual-source CT system is composed of two x-ray tubes and two corresponding detectors. The two acquisition systems are mounted on the rotating gantry with an angular offset of 90° (first-generation dual-source CT) or 95° (second-generation dual-source CT). Dual-energy (DE) CT angiography allows differentiation of materials based on their energy absorption characteristics and has been proposed as a method to aid in the detection of PE (6–10).

You will not notice any difference in the examination whether you have a single energy or dual energy CT. Are there any after effects of a dual energy CT scan? Dual energy CT itself is not associated with any immediate after effects.
