Chest Imaging Techniques and Interpretation

These flashcards cover key terminologies and concepts related to chest imaging techniques, including X-rays, CT scans, MRIs, and important indicators and interpretations associated with chest X-rays.

X-ray

A form of electromagnetic radiation that creates images of the inside of the body.

Radiopaque

Substances that do not permit X-rays to pass through and therefore appear white on the X-ray film, indicating a dense substance.

Radiolucent

Substances that allow X-rays to pass through and appear black on the X-ray film, indicating a less dense substance.

Pleural effusion

Accumulation of fluid in the pleural space, which can be identified by blunting of the costophrenic angle on an X-ray.

Atelectasis

Collapse or incomplete expansion of the lung, which can be observed on X-ray as an area of increased density.

Consolidation

The process where normally air-filled lung tissue becomes filled with fluid, leading to a solid appearance on X-ray, often indicative of pneumonia.

Carina

The ridge where the trachea divides into the right and left main bronchi, often referenced for verifying the placement of endotracheal tubes.

CT scan

A medical imaging technique that uses a combination of X-rays and computer technology to produce detailed cross-sectional images of the body.

MRI (Magnetic Resonance Imaging)

An imaging technique that uses powerful magnets and radio waves to create detailed images of organs and tissues without using ionizing radiation.

Pneumothorax

A condition in which air enters the pleural space, leading to lung collapse, detectable by the absence of lung markings and presence of free air on an X-ray.

Mediastinal shift

Movement of the mediastinum to the opposite side of a chest cavity due to pressure changes, often observed in cases of severe pneumothorax.

Central venous pressure (CVP)

A measure of the pressure in the thoracic vena cava, which reflects the amount of blood returning to the heart and the heart's ability to pump it into the arterial system.

Consolidation

A type of lung tissue alteration where the tissue becomes solid due to fluid accumulation, often due to pneumonia.

Air bronchogram

The appearance of air-filled bronchi surrounded by consolidated lung tissue on an X-ray, indicating an area of pneumonia.

Curly B lines

Linear opacities seen on X-ray indicative of pulmonary edema; associated with heart failure.

Blunted costophrenic angle

A sign on chest X-ray suggesting pleural effusion, where the normally sharp angle between the diaphragm and ribs becomes rounded.
