Module 1: Ultrasound Fundamentals Flashcards
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
Infection
Invasion of microorganism causing disease
Inflammation
Reaction occurring in response to injury
Ischemia
Decrease blood supply causing injury or death
Necrosis
Death of cells, tissue or organ
Neoplasm
Abnormal tissue growth due to proliferative. Any abnormal growth that could be B9 or malignant
Prognosis
Forecast of probable outcome of disease
Sign
Finding during a physical exam
Symptom
Complaint from a patient
