This study aimed to work out the age-related performance of prospective gating, as compared with retrospective sorting. Prospectively gated 4D magnetic resonance imaging scans were nonheritable on a motion phantom driven by real metastasis waveforms obtained from twenty-three paediatric and young adult patients (aged 5–24â?¯years). The correlations between patient-specific respiratory characteristics and also the performance of 4D magnetic resonance imaging were relatively evaluated against retrospective sorting for constant scan time.
