In trauma with suspected injury, which imaging is part of the primary survey?

• A. Chest X-ray, Pelvic X-ray, and FAST exam
• B. CT scan of the chest
• C. MRI brain
• D. Abdominal ultrasound only

Answer: (B)

In trauma, the primary survey focuses on identifying and addressing immediate life-threatening problems as quickly as possible, using imaging that can be done at the bedside or with minimal delay. The imaging that belongs to this stage includes a FAST exam to look for free fluid or pericardial tamponade, along with chest and pelvic X-rays to rapidly detect major thoracic injuries like pneumothorax or hemothorax and pelvic fractures. These tests provide essential information without delaying resuscitation. A CT scan of the chest, while very informative, is not part of the primary survey because it requires moving the patient to the radiology suite and more time, which isn’t appropriate during the initial resuscitation. It’s typically used after initial stabilization or as part of the secondary survey when the patient is hemodynamically stable. An MRI brain isn’t used in the primary survey due to time constraints and availability. An abdominal ultrasound alone would miss injuries in the chest and pelvis, making it insufficient for the comprehensive initial assessment. So the imaging that fits the primary survey best is chest X-ray, pelvic X-ray, and the FAST exam.
