Abstract

3D multi-echo gradient-recalled echo (ME-GRE) can simultaneously generate time-of-flight magnetic resonance angiography (pTOF) in addition to T2*-based susceptibility-weighted images (SWI). We assessed the clinical performance of pTOF generated from a 3D ME-GRE acquisition compared with conventional TOF-MRA (cTOF).Eighty consecutive children were retrospectively identified who obtained 3D ME-GRE alongside cTOF. Two blinded readers independently assessed pTOF derived from 3D ME-GRE and compared them with cTOF. A 5-point Likert scale was used to rank lesion conspicuity and to assess for diagnostic confidence.Across 80 pediatric neurovascular pathologies, a similar number of lesions were reported on pTOF and cTOF (43-40%, respectively, p?>?0.05). Rating of lesion conspicuity was higher with cTOF (4.5?±?1.0) as compared with pTOF (4.0?±?0.7), but this was not significantly different (p?=?0.06). Diagnostic confidence was rated higher with cTOF (4.8?±?0.5) than that of pTOF (3.7?±?0.6; p?
