no treatment control/standard of care control

single assignment

diagnostic purpose

1) Be an adult over 20 years old
2) Written informed consent
3) Patients suspected of chest trauma or patients diagnosed with chest trauma
4) Chest CT contrast test scheduled for diagnosis or follow-up of chest trauma

1) have allergy to the contrast agent
2) During pregnancy, possibility of pregnancy, delivery within 28 days, breast-feeding
3) Psychiatric disorder or psychiatric symptoms are merged and it is judged difficult to participate in the trial
4) Severe cases (during artificial respiration, SpO2 <93% even when administered oxygen, wearing an extracorporeal circulation assisting device, shock index> 1, during noradrenaline administration, GCS <13)
5) Even if it does not apply to 4) above, the patient who judged treatment as priority by the attending physician
