Indication/contradictions Flashcards
3 stages of minimally invasive procedures?
- pre-procedure
- intra-procedure
- post- procedure
what has rapidly become the modality of choice for the guidence of some interventional therapeutic and diagnostic procedures?
Ultrasound
less invasive ultrasound guided interventional procedures have resulted in what?
- reduced numbers of surgical procedures
- providing more responsive delivery of treatment
- reduced patient mortality and morbidity
what is an indication?
- a symptom that suggests certain medical intervention is necessary
what is a contraindication?
specific situation in which a drug, procedure or surgery should not be used because it may be harmful to the patient
examples of ultrasound-guided biopsy? (9)
- liver
- renal
- extravisceral abdominal mass
