Which of the following actions will help reduce heating? Select all that apply.

Enabling parallel imaging is indeed an action that can help reduce heating during MRI scans. Parallel imaging techniques utilize multiple receiver coils to acquire data simultaneously, which shortens the scan time. A shorter scan time means that the patient is exposed to the magnetic field and radiofrequency (RF) pulses for a lesser duration, thereby reducing the overall energy absorbed by the tissues and consequently minimizing the risk of heating.

In addition to parallel imaging, the other options also contribute in various ways to temperature management during scans: decreasing echo train length (ETL), increasing receiving bandwidth, and increasing frequency encoding all serve different purposes but may not be directly effective in reducing heating in the same manner. Understanding these techniques helps in optimizing patient safety and comfort during MRI procedures.
