Dual-Energy CT Applications in Urological Diseases

Applied Sciences, 2023
Dual-energy computed tomography (DECT) is a medical imaging technique that uses two different energy levels of X-rays to provide more detailed information about the composition of tissues and materials within the body. DECT technology is still relatively
