    A chest X-ray may be performed afterwards to confirm that the line is positioned inside the superior vena cava and no pneumothorax was caused inadvertently. On anteroposterior X-rays, a catheter tip between 55 and 29 mm below the level of the carina is regarded as acceptable placement. [ 37 ]

  3. Subcutaneous emphysema - Wikipedia

    en.wikipedia.org/wiki/Subcutaneous_emphysema

    These cases result in immediate onset (usually) painless swelling of the face and neck; crepitus (crunching sound) typical of subcutaneous emphysema is often present and the subcutaneous air will be visible on X-ray. [24] One of the main causes of subcutaneous emphysema, along with pneumothorax, is an improperly functioning chest tube. [2]

  4. Chest radiograph - Wikipedia

    en.wikipedia.org/wiki/Chest_radiograph

    AP chest x-rays are harder to read than PA x-rays and are therefore generally reserved for situations where it is difficult for the patient to get an ordinary chest x-ray, such as when the patient is bedridden. In this situation, mobile X-ray equipment is used to obtain a lying down chest x-ray (known as a "supine film").

    Chest retractions may be observed in patients with asthma. During a chest retraction, the patient's skin appears to sink into the chest. During supra-sternal retractions, the skin of the neck appears to sink in as the accessory breathing muscles of the neck contract to aid with inspiration.

    Chest x-ray is the initial imaging technique used to diagnose TBI. [17] The film may not have any signs in an otherwise asymptomatic patient. [15] Indications of TBI seen on radiographs include deformity in the trachea or a defect in the tracheal wall. [17] Radiography may also show cervical emphysema, air in the tissues of the neck. [2]

  7. Projectional radiography - Wikipedia

    en.wikipedia.org/wiki/Projectional_radiography

    Tissues commonly imaged include the lungs and heart shadow in a chest X-ray, the air pattern of the bowel in abdominal X-rays, the soft tissues of the neck, the orbits by a skull X-ray before an MRI to check for radiopaque foreign bodies (especially metal), and of course the soft tissue shadows in X-rays of bony injuries are looked at by the ...

    Symptoms typically include sudden onset of sharp chest pain, which may also be felt in the shoulders, neck, or back. [1] The pain is typically less severe when sitting up and more severe when lying down or breathing deeply. [1] Other symptoms of pericarditis can include fever, weakness, palpitations, and shortness of breath. [1]

    Using early Crookes tube X-Ray apparatus in 1896. One man is viewing his hand with a fluoroscope to optimise tube emissions, the other has his head close to the tube. No precautions are being taken. Monument to the X-ray and Radium Martyrs of All Nations erected 1936 at St. Georg hospital in Hamburg, commemorating 359 early radiology workers.
