Ultrasound fundamentals Part 1 Flashcards
What is the sonographers role?
- access soft tissue and vascular structures
- Differentiate normal and abnormal
- document pertinent findings
- communicate findings
What is echogenicity?
Number of echoes produced
What is echotexture?
Echo pattern within an organ or structure
What does echogenic mean?
A structure that produces echoes
What does anechoic mean?
Without internal echoes
What does hyper echoic mean?
An increased number of echoes. (describes the comparison to an adjacent structure, or brighter then other structures)
What does Hypoechoic mean?
Fewer echoes in a structure compared to another structure (a structure that is darker then another)
What does isoechoic mean?
A structure that is the same echogenicity as an adjacent area
What does Homogeneous mean?
- Uniform echoes throughout a structure
- Describes the parenchymal texture of several organ
What does heterogeneous mean?
Uneven textural pattern throughout a structure
What does parenchyma mean?
Organ tissue
What does acute mean?
Sudden onset of signs and symptoms
What does afebrile mean?
W/O fever
What does atrophy mean?
Wasting, decrease in size
What does chronic mean?
Gradual onset; health related state lasting a long time
What does complication mean?
Develops as a result of a disease
What does congenital mean?
Existing at birth; may be hereditary or due to interference at some point in fetal development
What does emesis mean?
Vomiting
What does etiology mean?
Cause of disease
What does genetic mean?
Abnormality due to the defective genes
What does hypertrophy mean?
Increase in size of an organ due to an increase in cell size
What does latogenic mean?
Response occurring as a result of treatment W
What does latogenic mean?
Response occurring as a result of treatment
What does idiopathic mean?
Unknown cause
What does infarction mean?
Insufficiency of blood supply causing necrosis
What is an infection?
Invasion of microorganism causing disease
What does inflammation mean?
Reaction occurring in response to injury
What does ischemia mean?
Decrease blood supply causing injury or death of tissue
What does necrosis?
Death of cell, tissue or organ
What does neoplasm?
Abnormal tissue growth due to an proliferation of cells
What is a prognosis?
Forecast of probable outcome of disease
What is a sign?
Finding during a physical exam
What is a symptom?
Compliant from a patient
