The correct choice of an SED (Specific Absorption Rate Exposure Dose) limit for patients with thermal regulation compromise is 100 W-min/kg (6000 J/kg). This limit is established to ensure the safety of patients who may not be able to effectively regulate their body temperature. The thermal regulation compromise could lead to an increased risk of overheating during MRI procedures due to the radiofrequency energy absorbed by the body.
In such patients, it is crucial to minimize the risk of excessive thermal loading, which is why a lower exposure dose limit is set. The choice represents a balance between ensuring diagnostic quality and protecting vulnerable patients from potential overheating, which could result from longer or more intense imaging sessions.
By maintaining this limit, healthcare providers can help ensure that the risks associated with MRI scanning in patients with thermal regulation issues are kept to a minimum, ultimately safeguarding patient health and comfort.
