Dual Energy CT Systems (Not Photon Counting)

Dual Energy CT Systems enable material specific imaging rather than traditional Hounsfield Units.
There are several CT scanner designs for achieving dual energy CT.
These include:
Fast kVp Switching
Deep Learning kVp Switching
Split Filter Systems
Dual Source CT
Dual Layer CT
Rotate-Rotate CT
We introduce the different CT system designs and compare them systematically.

Great talk. Thanks. What is the difference between monoenergetic virtual DECT VS Iodine map DECT?

[@HowRadiologyWorks]

Monoenergetic image has contrast more similar to traditional CT but without beam hardening. Iodine maps have water signal suppressed so will just highlight iodine uptake. Since bone is in both iodine and water images you will see that in both

Very informative and understandable video.

Thanks that’s what we’re going for 🤗
