A NCE-MRA technique using steady-state free precession (SSFP) and flow-sensitive dephasing (FSD) magnetization preparation has been recently proposed for peripheral noncontrast (NCE) MRA. The purpose of this study was to prospectively assess the diagnostic performance of the NCE-MRA technique in patients with diabetes, using conventional CE-MRA as the reference standard. In 38 healthy volunteers and 38 diabetic patients, NCE-MRA showed significant higher image quality scores than CE-MRA. In addition, NCE-MRA provided comparable SNR and CNR in dorsal artery and lateral plantar artery compared to CE-MRA and significant higher in pedal artery. Diagnostic accuracy was excellent by using NCE-MRA.
