Xray interpretation Flashcards
What are air leaks in a medical context?
Abnormal escape of air from the lung or airway into the surrounding tissues or pleural space
Commonly associated with conditions like pneumothorax and respiratory distress syndrome.
What does ETT stand for?
Endotracheal Tube
A tube inserted into the trachea to maintain an open airway.
What is the purpose of an OG tube?
Orogastric Tube
Used for feeding or medication administration in patients unable to swallow.
What does UAC stand for?
Umbilical Artery Catheter
A catheter placed in the umbilical artery for monitoring and medication administration.
What does UVC refer to?
Umbilical Vein Catheter
Used for intravenous access in neonates.
What are central lines used for?
Long-term intravenous access
Allows for the administration of medications, fluids, and nutrition.
What condition is characterized by difficulty in lung expansion?
Respiratory Distress Syndrome
Commonly seen in premature infants due to surfactant deficiency.
TTN stands for what in a medical diagnosis?
Transient Tachypnea of the Newborn
A temporary condition causing rapid breathing in newborns.
What is pneumonia?
An infection that inflames the air sacs in one or both lungs
Can cause symptoms such as cough, fever, and difficulty breathing.
What are the factors affecting the quality of chest X-rays?
Positioning, motion, tube angulation, film exposure
Proper technique is crucial for accurate interpretation.
What does an inspiratory film show?
8 to 9 ribs expanded, normal cardiac size, right hemidiaphragm higher than left
Indicates proper lung inflation.
What indicates an expiratory film?
7 ribs expanded or less, large cardiac size, lung fields opaque
Suggests inadequate lung expansion.
What is the significance of film exposure in X-ray interpretation?
Underexposed films appear whitewashed; overexposed films appear too dark
Proper exposure is essential for visualizing anatomical structures.
What does the term ‘hypoexpansion’ refer to?
Inadequate lung inflation
Often indicated by the number of ribs visible on an X-ray.
What is the basic principle of radiology concerning x-ray absorption?
Differential absorption of x-ray photons by different types of body tissue produces an image
Tissues absorb varying amounts of x-ray photons based on density.
What are the four kinds of body tissue that can be differentiated in X-ray imaging?
- Tissue containing gas
- Fatty tissue
- Tissue containing calcium
- Tissues of water density
Each type appears differently on X-ray films.
What does NEC stand for in a medical context?
Necrotizing Enterocolitis
A serious gastrointestinal problem that mostly affects premature infants.
Fill in the blank: Bone and metal fragments absorb x-ray photons and appear ______ on film.
white
This is due to their high density.
Fill in the blank: Liquid and tissue appears ______, although less dense than air.
white
Important for differentiating various tissues in imaging.
True or False: The right patient, right time, and right view are critical for effective X-ray interpretation.
True
Accuracy in patient identification and timing enhances diagnostic reliability.
