WebJun 27, 2008 · In 63 pazienti l’indagine TCMD è stata effettuata con gating cardiaco retrospettivo e modulazione della dose, ricostruendo la finestra temporale corrispondente al 75% dell’intervallo RR dell’ECG. Nei restanti 12 pazienti non è stato possibile utilizzare il gating cardiaco per la presenza di FA ad alta frequenza. Risultati WebMar 23, 2024 · Purpose. The purpose of the prospective ECG-gated high-pitch dual-source is opacification of the coronary arteries without motion artifacts. This is achieved best by prospectively scanning at the mid to end-diastolic phase (around 70% of the R-R interval) 1 . The exam is fast (250-300 milliseconds) 2-4 but requires cooperative patients, a ...
