When scanning in FPO:basic, which statements are applicable? Select all that apply.

In the context of Magnetic Resonance Imaging (MRI) safety and operation, understanding the parameters for scanning is crucial. The correct choice is based on established safety protocols and the physics of MRI operation.

A peak dB/dt (the rate of change of the magnetic field) of 100 T/s is an acceptable threshold in many MRI systems and does not exceed safety limits established for basic functional protocols in MRI. This allows for sufficient gradient performance during scans while ensuring patient safety and compliance with guidelines.

The choice regarding scanning at 1.5T or less speaks to the operational capabilities of various MRI systems. While certain systems are designed to operate at a range of field strengths, the specific context of FPO:basic is not restricted to 1.5T. Therefore, while 1.5T is commonly used, it's not a blanket requirement.

The B1+rms value of 3.2 microtesla pertains to the RF (radiofrequency) fields used in imaging. The FPO:basic protocol typically operates within safe and predetermined RF levels, yet this specific threshold may not be the only permissible limit. In practice, RF safety levels can vary based on the scanner and specific conditions.
