H3, h6: siemens healthineers completed a detailed investigation of the reported event.Siemens healthineers experts analyzed the log files generated during the patient¿s examination.The complete examination of the patient¿s tmj scan lasted 29.6 min with an active scanning time of 24.5 min.No abnormality was found, which would indicate a system malfunction.The complete measurement was performed in normal operating mode.The sar values were within the limits defined by the mr safety standard (iec (b)(4)), i.E.The maximum applied sar was 27.9 % (whole body sar) / 98.3 % (head sar) of the normal mode limit.The applied rf in this case should not represent a risk under normal circumstances and scan conditions.Furthermore, the patient absorbed 14.2 wmin/kg which is clearly below the limit of 240 wmin/kg defined in the mr safety standard (iec (b)(4)).The system and the used rf coils were checked by our service engineer and found to be in specification.In summary no hardware or software problem was found which would explain the patient¿s problems.
