説明
SWI and MRA employ the FLASH sequence of gradient echo, and there are many similarities in acquisition parameters between the 2 sequences. We designed an acquisition sequence for the simultaneous collection of SWI and MRA. MRA images were simultaneously collected by changing the TE of the SWI sequence to double echo. The first TE was set to 6.15 msec, 8.61 msec, 11.10 msec of the opposed phase to acquire MRA information. The second TE was set to 20.00 msec to acquire magnetic susceptibility-weighted image information. Double echo, MRA, and SWI were performed in 6 volunteers. The MRI system used was the MAGNETOM Trio A Tim System of SIEMENS Co. Magnetic susceptibility-weighted and MRA images could be simultaneously collected. Evaluation of the main trunk of the cerebral artery in the MRA image was possible, but blood vessels became poorly imaged with transition toward the periphery. Arteries and veins were imaged due to the change to double echo on magnetic susceptibility-weighted imaging. The TE to acquire the best MRA was 6.15 msec of the opposed phase. The imaging of blood vessels by simultaneously collected MRA was impaired because of the inability to use TONE and a short TE. Arteries and veins were imaged by susceptibility-weighted imaging because flow compensation did not function at the second TE.
