Abstract:
Objective: To demonstrate the use of a portable X-ray system at the scene. Patient: A 59-year-old man collapsed under a small power shovel and was discovered by his colleague. The fire department dispatched an ambulance and requested the dispatch of a doctor helicopter (DH) immediately after receiving the emergency call. When the staff of the DH used a portable X-ray system to assess the patient at the rendezvous point, he was found to have experienced a cardiac arrest with deformity of the face. Portable chest X-ray in the ambulance revealed decreased radiolucency of the lung fields without pneumothorax, and tracheal tube insertion was successful. Portable pelvic X-ray also showed no trauma. Portable cranial X-ray revealed orbital fracture. Although we urgently transported the patient to our hospital by the DH, he unfortunately died of circulatory arrest caused by his severe injuries. Based on the portable X-ray findings obtained at the scene, we suspected that the patient's cardiac arrest had been caused by severe head and/or neck injuries. Conclusion: This portable X-ray system may be able to change and facilitate the management of patients with trauma dramatically by simplifying prehospital diagnoses even in rural areas.

Imaging Studies for Cardiovascular System III: X-Ray
Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...

History:
Computed Tomography
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...

Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...
