Background:
Fujifilm (Tokyo, Japan) developed a portable X-ray system called the CALNEO Xair, which can be carried by a physician. The X-ray radiation machine weighs 3.5 kg. The dimensions are: height, 144 mm; length, 148 mm; width, 258 mm.
Case Presentation:
When a 33-year-old woman driving a car made a right turn at a crossroad, her car hit another car, causing her vehicle to tip onto its side. Staff of the doctor helicopter checked her at the scene, and the findings of chest and pelvic X-ray were all negative. She received a diagnosis of cervical sprain and pelvic contusion and was transferred to a local hospital by ambulance.
Conclusion:
This is the first report of a case evaluated by a portable X-ray system at the scene, under transportation by a doctor helicopter. This system could be useful for undertaking prehospital assessment and medical treatment.

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...

Radiological Investigation I: X-ray and CT
Radiological Investigation III: Pulmonary Angiogram and PET Scan
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...
Radiological Investigation II: MRI and Ventilation Perfusion Scan
Magnetic Resonance Imaging (MRI) and Ventilation Perfusion Scans are two radiological investigations that offer detailed diagnostic images of the body, particularly lung structures.
MRI
MRI uses magnetic fields and radiofrequency signals to distinguish between normal and abnormal tissues. This technology provides a more detailed diagnostic image than CT scans, enabling it to characterize pulmonary nodules, stage bronchogenic carcinoma, and evaluate inflammatory activity in...
