Chest injury, is it just a positive film or a positive film?

I am a senior radiologist. Let me explain something to you.

Chest trauma, first of all, need to take a straight X-ray, generally according to the different parts of the injury, but also need to take oblique or local tangent X-ray. When the patient's pain is obvious and no fracture is found on the conventional chest radiograph, it is necessary to rotate the patient under TV fluoroscopy and let him press the most obvious pain with one finger, so as to find the fracture without dislocation. Because the ribs are oblique and there is mediastinal overlap, it is not enough to just take the chest position. When a sternal fracture is suspected, the chest lateral position or sternal lateral position should be adopted.
