Résumé
Radio frequency (RF) pulses in magnetic resonance imaging (MRI) can interact with implanted devices and cause tissue damage. However, there are new devices that can safely perform measurements with liberal MRI conditions such as an RF transmission field B We selected typical MRI protocols of six body regions (brain, cervical spine, lumbar spine, knee, liver, heart) using two typical 1.5T MRI scanners. Overall, we adapted 62 sequences to B Roughly one-third of the checked sequences were below the B By limiting the transmission field to B • Despite limiting the transmission field, high-quality MRI is possible. • We could derive strategies for adapting the sequences to B
