Feasibility of ultra-low flow rate coronary CT angiography using photon-counting detector CT: a prospective randomized trial
First validation of ultra-low flow contrast rate CCTA using photon-counting CT (PCD-CT). Ultra-low flow rates maintain objective image quality (CNR/SNR) versus routine protocols. PCD-CT enables 50% contrast reduction without diagnostic compromise.
