In FAST/Trauma ultrasound, the costophrenic angle refers to the acute angle formed by the diaphragm and the chest wall. This anatomical landmark is crucial during a FAST (Focused Assessment with Sonography for Trauma) exam to identify potential fluid collections like hemothorax. A blunted or obscured costophrenic angle on ultrasound can indicate fluid accumulation in the pleural space, guiding rapid diagnosis and intervention in trauma patients.
Efficient visualization of the costophrenic angle is vital for assessing thoracic injuries. Sonographers utilize specific probe placements to adequately image this region, ensuring comprehensive evaluation of the lungs and pleural cavities. Understanding the normal and abnormal appearance of the costophrenic angle significantly enhances diagnostic accuracy in emergency ultrasound, making it a key focus for trauma care.
