Background: Inflow-sensitive inversion recovery (IFIR) is a recently introduced technique to perform unenhanced magnetic resonance angiography (MRA). The purpose of our study is to determine the accuracy of IFIR-MRA in the evaluation of upper abdominal arteries, compared to standard MRA and computed tomography angiography (CTA).

GE's version is called Inhance Inflow IR (IFIR), while Philips uses B-TRANCE ("Balanced TRiggered Angiography Non-Contrast Enhanced). Hitachi calls their method VASC-ASL ("Veins and Arteries Sans Contrast - Arterial Spin Labeling") and Cannon Time-SLIP ("Time Spatial Labeling Inversion Pulse)" .

Magnetic resonance angiographic inflow-sensitive inversion recovery (IFIR-MRA) is a new noncontrast technology for vascular evaluation, particularly for those patients with renal function impairment. The purpose of this study was to improve the image quality with different blood suppression inversion time (BSP TI) settings.

2022年3月28日 · Reviewer 2 Report. This manuscript explores the potentials for contrast agent free magnetic resonance angiography (MRA) based on Inflow Inversion Recovery (IFIR). The method is compared to computed tomography angiography and MRA using contrast agents. The study involves 70 patients and concludes that IFIR-MRA is the superior method in
