Esophageal Dilatation

The esophagus, which is the tube that carries food from the mouth to the stomach, can become narrowed and cause swallowing difficulty. Causes of this narrowing include stricture formation, usually after surgery, allergies, or even injury from caustic substances. Dilatation is when a high-pressure balloon is inserted into the esophagus and inflated to open up these narrowed portions.

Fine Needle Aspiration

In a fine needle aspiration procedure, a doctor will insert a very thin needle into the gland and withdraw a tiny sample of tissue or fluid. Learn more about this procedure.

Magnetic Resonance High Intensity Focused Ultrasound (MR-HIFU)

A Magnetic Resonance High Intensity Focused Ultrasound (MR-HIFU) is a procedure in which a radiologist uses the aid of magnetic resonance imaging to focus an ultrasound beam into lesions, usually tumors of the bone, to heat and destroy the tissue in that region.
