This study compared the differences between PETRA-MRA and TOF-MRA on the imaging of the cavernous segment of the ICA with qualitative analysis (image quality) and quantitative analysis (SNR, CNR, CR, and uniformity). The results showed that PETRA-MRA significantly improved the uniformity and CR of the cavernous segment of ICA, although it is inferior in both SNR and CNR. This suggests that PETRA-MRA could provide a reasonable alternative to reduce the loss of signal from curved vessels.
