Fast comprehensive single-sequence four-dimensional pediatric knee MRI with T₂ shuffling.

ABSTRACT:

Purpose

To develop and clinically evaluate a pediatric knee magnetic resonance imaging (MRI) technique based on volumetric fast spin-echo (3DFSE) and compare its diagnostic performance, image quality, and imaging time to that of a conventional 2D protocol.

Materials and methods

A 3DFSE sequence was modified and combined with a compressed sensing-based reconstruction resolving multiple image contrasts, a technique termed T₂ Shuffling (T₂ Sh). With Institutional Review Board (IRB) approval, 28 consecutive children referred for 3T knee MRI prospectively underwent a standard clinical knee protocol followed by T₂ Sh. T₂ Sh performance was assessed by two readers blinded to diagnostic reports. Interpretive discrepancies were resolved by
