However, this study cannot be performed for those who have contraindications to MR contrast agents. Balanced turbo field-echo (bTFE) sequence enables static and moving fluids to be shown as high intensity without the use of gadolinium. We assessed the feasibility of follow-up non-contrast-enhanced MRA using bTFE sequence for posttreatment VAA. Combined bTFE and unenhanced fat-suppressed T1-wighted (FS-T1W) images demonstrated excellent performance for the diagnosis of aneurysm reperfusion comparable to combined dynamic contrast-enhanced and unenhanced FS-T1W images.
