Which imaging modality is used in AFAST/TFAST examinations?

• A. Ultrasound
• B. X-ray
• C. MRI
• D. CT

Answer: (A)

AFAST/TFAST use ultrasound as the imaging modality. These are bedside, rapid ultrasound protocols designed to quickly scan the abdomen and, in the case of TFAST, the chest for free fluid or other abnormalities in trauma patients. Because ultrasound provides real-time imaging with a portable hand-held probe, it can be performed at the patient’s side, is repeatable, and does not involve ionizing radiation. This makes it ideal for unstable patients where time is critical. Other imaging options like X-ray, MRI, or CT require more equipment, transport, or time, and are not what these focused trauma examinations rely on.
