What strategy can be used to keep gradient effects to a minimum during MRI?

Keeping the dB/dT (the rate of change of the magnetic field with respect to time) below certain limits is crucial for minimizing peripheral nerve stimulation (PNS) during MRI. High rates of change in the magnetic field strength can induce currents in the body, which may lead to undesirable nerve stimulation and discomfort for the patient. By adhering to established thresholds for dB/dT, technologists can reduce the likelihood of PNS occurring during scanning, ensuring a safer and more tolerable experience for the patient.

Maintaining this limit helps to optimize imaging quality as well, since excessive rates of change might interfere with the overall performance of the MRI system. Therefore, focusing on the safe management of dB/dT is a strategic and effective way to mitigate gradient effects within the context of MRI operations.
