Interventional Procedures

Interventional procedures are performed using x-ray equipment and ultrasound. At MGH, the most common interventional procedure is a Peripherally Inserted Central Catheter (PICC) Line insertion. The procedures are performed by a radiologist, medical radiation technologist and diagnostic imaging nurse.

What to expect

A PICC is a long, thin tube that goes into a vein in your upper arm. A PICC is used when you need intravenous medical treatment over a long period of time. The technologist and/or radiologist will obtain medical history, check allergies, explain the procedure, explain risks and will require written consent.

  • You will lie on your back on the x-ray table.
  • A tourniquet is tied around your arm near your shoulder.
  • The area where the needle is inserted is cleaned.
  • Ultrasound is used to choose the vein and guide the needle into your vein. It looks inside your body with a device that is moved over your skin.
  • The area where the needle is inserted is numbed. This may sting for a moment.
  • A needle is inserted, then a guide wire and catheter. The guide wire and catheter are moved through your vein into the proper spot, the Superior Vena Cava (SVC).
  • During this process, the needle puncture site is made a little larger with a scalpel. This does not hurt.
  • The examination will take approximately 30-45 minutes.
