Module 1: Ultrasound Fundamentals Flashcards
(32 cards)
Echogenicity
Amount of echoes produced
Echotexture
Echo pattern within an organ or structure
Echogenic
Structure that produces echoes
“Echo-rich”
Anechoic
Structure without internal echoes (not necessarily cystic)
Hyperechoic
Increased amount of echoes (always compared to adjacent structures)
Hypoechoic
Few echoes in a structure
Isoechoic
A structure that has the same echogenicity as an adjacent structure
Homogenous
Uniform echoes throughout a structure, describes the parenchymal texture of several organs
Heterogenous
Uneven textural pattern
Necrotic
Tissue death (mixed echogenicity on ultrasound)
Parenchyma
Tissue
Acute
Sudden onset of signs and symptoms
Afebrile
Without a fever
Atrophy
Wasting, decreasing in size
Chronic
Gradual onset, health related state lasting a long time
Complication
Develops as a result of disease
Congenital
Existing at birth, may be hereditary or due to interference at some point I fetal development
Emesis
Vomiting
Etiology
Cause of disease
Genetic
Abnormality due to defective genes
Hypertrophy
Increase in size
Iatrogenic
Response occurring as a result of treatment
Idiopathic
Unknown cause
Infarction
Sudden insufficiency of blood causing necrosis
