chapter 6 penny Flashcards
the productions of bubbles in a liquid medium
acoustic cavitation
uses acoustic radiation force to compress the soft tissue and provides a qualitative measurement of stiffness without requiring pressure input from the sonographer
acoustic radiation force impulse imaging
mnemonic, which stands for “as low as reasonably achievable,” that is used to remind professionals to keep patient exposure to ultrasound at a minimum
ALARA
a portable device that is used to detect and treat abnormal heart rhythms with electrical defibrillation
automatic external defibrillator
type of imaging in which an ultrasound contrast agent containing microscopic gas bubbles is used to improve visualization of structures or blood flow
contrast-enhanced ultrasound (CEUS)
a group of metabolic diseases that result from a chronic disorder of carbohydrates metabolism
diabetes mellitus
a complication of diabetes that results from the severe lack of insulin
diabetic ketoacidosis
a sonographic technique used to evaluate the stiffness of a mass or tissue
elastography
the scientific study of creating tools and using equipment effectively in order to help the human body adjust to the work environment
ergonomics
technology that provides the ability to view alternate imaging modality during real-time sonography; also referred to as hybrid imaging
fusion imaging
US law, which, among many goals, upholds patient confidentiality and requires the use of electronic medical records
Health Insurance Portability and Accountability Act (
inflammation of the liver
hepatitis
a diabetic syndrome characteristics by excessive urination and dehydration
hyperglycemic hypersmolar nonketotic syndrome
a lower than normal blood sugar level
hypoglycemia
the technique that employs a miniature ultrasound transducer placed on a catheter and inserted into the circulatory system
intravascular ultrasound
the calculation used to identify the likelihood that cavitation could occur
mechanical index
a hospital-acquired infection
nosocomial infection
forces exerted by a sound beam on an absorber or reflector that can alter structures
radiation forces
elastography technique that uses shear wave information to analyze the stiffness of tissue
shear wave elastography
the body’s pathologic response to illness, trauma, or severe physiologic or emotional stress
shock
operator dependent type of elastography that measure the change in tissue as a result of compression
strain elastography
when acoustic fields cause motion of fluids
streaming
rapid heart rate; a rate that exceeds the normal rate for the person’s age
tachycardia
the calculation used to predict the maximum temperature elevation in tissues as a result of the attenuation of sound
thermal index
