MRI Safety in the Clinical Environment

Which organization issued the Sentinel Event Alert Number 38 regarding MRI safety in 2008?. American College of Radiology (ACR). The Joint Commission. Food and Drug Administration (FDA). American Society for Testing and Materials (ASTM).

According to ACR guidelines, what defines "Level 1" MRI Personnel?. Those with extensive training in thermal loading and neuromuscular excitation. Personnel who have passed minimal safety education to ensure their own safety in Zone 3. Individuals with no formal MRI safety training within the past year. The MRI Medical Director responsible for site policies.

Which MRI Safety Zone is described as the "MRI Scan Room" itself?. Zone 1. Zone 2. Zone 3. Zone 4.

Where should the safety screening for non-MRI personnel take place?. Inside the MRI Scan Room (Zone 4). In the control room (Zone 3). Outside of Zone 3, typically in Zone 2. At the hospital’s main reception.

How many separate individuals should a non-emergent patient screen before they enter the MRI environment?. One. Two. Three. Four.

What is the danger of "athletic tech clothing" (e.g., Tommy Copper, Lululemon) in an MRI?. It can cause image artifacts due to the thickness of the fabric. It may contain metallic microfibers that cause skin burns. The compression can interfere with the patient's heart rate monitoring. It can become magnetic and fly toward the bore.

An item labeled "MR Conditional" means: It is safe for use in all MRI environments. It is known to pose hazards in all MRI environments. It poses no known hazards under very specific conditions of use. It is compatible with any MRI scanner regardless of field strength.

Who has the final responsibility for determining if a patient with an implant can safely undergo an MRI?. The Referring Physician. The MRI Technologist. The Attending MR Radiologist or Medical Director. The Patient.

Why is "skin-to-skin" contact (like crossed legs or hands on hips) dangerous during an MRI?. It causes the patient to sweat more, increasing SAR. It can form a "large caliber loop" that leads to RF burns. It prevents the technologist from seeing the patient’s anatomy clearly. It interferes with the gradient magnetic field's ability to switch.

What should be done if a medical emergency (like a cardiac arrest) occurs inside the scan room?. Begin the code immediately next to the magnet. Use only MR-safe defibrillators inside Zone 4. Immediately move the patient out of Zone 4 to a designated area before starting treatment. Shut down the magnet's field (Quench) before treating the patient.
