Real-time phase contrast sequences versus conventional phase contrast sequences in cerebral blood flow quantification: an in vivo study
Séquences de contraste de phase en temps réel par rapport aux séquences de contraste de phase conventionnelles dans la quantification du débit sanguin cérébral : une étude in vivo
Résumé
The accuracy of real-time phase contrast sequences (RT-PC) was confirmed by comparison with conventional phase contrast sequences. RT-PC with 2×2 mm 2 spatial resolution and 75ms/image temporal resolution can accurately quantify cerebral blood flow rate with less than 3% of error. Synopsis (100/100) Real-time phase contrast sequences (RT-PC) appear to have great potential in clinical applications. However, it is important to validate RT-PC in the quantification of cerebral blood flow prior to its use in clinical applications. In this study, we analyzed RT-PC accuracy by comparing the segmentation area, flow rate and pulsatility index of cerebral vessels obtained from RT-PC and conventional phase contrast sequences. RT-PC with 2×2 mm 2 spatial resolution and 75ms/image temporal resolution can accurately quantify cerebral blood flow rate with an error of less than 3%. Higher temporal resolution in RT-PC could improve accuracy in cerebral arterial flow quantification.
