Intravascular Ultrasound Ivus

Intravascular Ultrasound

Intravascular Ultrasound (IVUS) is a medical imaging methodology, which uses an ultrasound probe that is inserted to the artery like a regular angioplasty catheter to provide an image from within the artery.

Used to see the inside blood vessels using soundwaves. A computer produces pictures of soft tissues. This technique allows physicians to see areas that they can’t see with X-rays

Cardiologists use IVUS to visualize exactly location of plaque, which helps determining whether stenting is possible, or whether a patient might require surgery.

IVUS are also used to assess stents that have already been inserted & whether they have expanded properly.

  • Transducer/ Probe emits the soundwaves
  • Bounce of Soft tissues- creating an echo
  • Probe is sent via catheter to the targeted area
  • Other end of catheter is connected to a computer
  • Computer uses echoes to create a clear image
  • Physician sees the inside of your arteries or veins

  • To view the artery from inside out
  • To Determine- Bypass sugery or Angiplasty
  • Looking for blood clots
  • Reveal plaque build up in arteries
  • Adequcy of stent deployment
