Summary
OBJECTIVE: For cochlear implant recipients, present process magnetic resonance imaging (MRI) scans is related to security dangers and potential negative effects. Even following security pointers, potential problems (e.g., ache, magnet dislocation, picture artifacts) are doable throughout 1.5 Tesla (T) MRI scans. The stronger static magnetic area of a three.zero T scanner is related to additional dangers of complication, together with implant demagnetization. These problems led to the current growth of rotatable inside receiver magnets with a diametrical magnetization.The purpose of this examine was to judge the potential incidence of ache throughout three.zero T MRI scans for cochlear implant recipients with a rotatable, diametrically magnetized implant magnet.
PATIENTS: 5 sufferers implanted with a cochlear implant diametrically magnetized magnet.
INTERVENTION: MRI scanning at three T.
MAIN OUTCOME MEASURE: Within the potential affected person examine an MRI scan was carried out on 5 implantees and the diploma of ache was evaluated by a visible analog scale. Scans had been carried out initially with a magnet-supporting headband, and relying on the diploma of discomfort/ache, repeated with out the scarf.
RESULTS: In all of the sufferers, all of the MRI scans had been carried out with none ache, even with out the usage of the supportive headband. Demagnetization was clinically not noticed.
CONCLUSION: three.zero T MRI scanning may be carried out on cochlear implant recipients with a rotatable diametrically magnetized inside magnet with out threat of essentially the most frequent cochlear-implant-related MRI complication: ache. This discovering permits the enlargement of MRI scanning indications as much as three.zero T with out complication. Limitations when it comes to MRI artifact nonetheless persist.
