|Imaging Guided Biopsy/ Abscess
One of the most beneficial techniques used
by the interventional radiologist is performing the biopsy of a mass or
draining a collection of fluid within the body without the need for surgery.
This is commonly done using a variety of imaging methods, including CT,
ultrasound, and fluoroscopy.
Using one of these methods for visualizing
the mass or fluid collection, the radiologist can guide a thin needle into
the area in question, avoiding other vital organs, and obtain fluid or
tissue for diagnostic testing.
In the case of an abscess, a thin wire
can be placed through the needle, over which a small tube (catheter) can
be inserted to drain the fluid without the need for surgery. Most areas
of the body can be safely reached in this way. The need for surgery can
be avoided, and no hospital stay is required in most cases.
Following is a description of the some
of the procedures RCT physicians perform, along with images that show the
dramatic findings and results produced using these techniques.
