  2. 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").

    For example, if the reader thinks the x-ray being read has profusion most like the standard x-ray for category 1, but serious considered category 2 as an alternative description of the profusion, then the reading is 1/2. Close-up right lower zone 2/2 S/S Large opacities: A large opacity is defined as any opacity greater than 1 cm in diameter.

  4. Ventilation/perfusion scan - Wikipedia

    en.wikipedia.org/wiki/Ventilation/perfusion_scan

    A ventilation/perfusion lung scan, also called a V/Q lung scan, or ventilation/perfusion scintigraphy, is a type of medical imaging using scintigraphy and medical isotopes to evaluate the circulation of air and blood within a patient's lungs, [1] [2] in order to determine the ventilation/perfusion ratio.

  5. Tuberculosis radiology - Wikipedia

    en.wikipedia.org/wiki/Tuberculosis_radiology

    However, lesions may appear anywhere in the lungs. In HIV and other immunosuppressed persons, any abnormality may indicate TB or the chest X-ray may even appear entirely normal. [1] Old healed tuberculosis usually presents as pulmonary nodules in the hilar area or upper lobes, with or without fibrotic scars and volume loss. [1]

  6. Haller index - Wikipedia

    en.wikipedia.org/wiki/Haller_index

    The Haller index, created in 1987 by J. Alex Haller, S. S. Kramer, and S. A. Lietman, [1] is a mathematical relationship that exists in a human chest section observed with a CT scan. It is defined as the ratio of the transverse diameter (the horizontal distance of the inside of the ribcage ) and the anteroposterior diameter (the shortest ...

  7. Reed's rules - Wikipedia

    en.wikipedia.org/wiki/Reed's_rules

    On every chest film, read the abdominal portion as you would read an abdominal film. Knowledge of anatomy is the key to correct radiographic diagnosis. The airway should be visible on all normal chest films. A mass must be seen in two planes. An esophagram must be done on any child with unexplained respiratory disease.

  8. Respiratory examination - Wikipedia

    Decreased chestchest movement on the affected side; An increased jugular venous pressure, indicating possible right heart failure [5] The anterior and posterior chest wall are also inspected for any abnormalities, which may include: Kyphosis, abnormal anterior-posterior curvature of the spine [6] Scoliosis, abnormal lateral curvature of the ...

  9. Pulmonary consolidation - Wikipedia

    en.wikipedia.org/wiki/Pulmonary_consolidation

    Typically, an area of white lung is seen on a standard X-ray. [5] Consolidated tissue is more radio-opaque than normally aerated lung parenchyma, so that it is clearly demonstrable in radiography and on CT scans. Consolidation is often a middle-to-late stage feature/complication in pulmonary infections.
