What are some types of cross-sectional interventional services (CIS)?

The following are some types of cross-sectional interventional services (CIS):
  • Biopsy: A tissue biopsy is performed to identify the type of tissue or fluid comprising your lesion. During imaging, small needles are guided to the lesion. Then a small amount of tissue or fluid is extracted for examination under the microscope. More than one needle pass is made to assure the removal of sufficient material at the designated sites.
  • Fluid Drainage: Using imaging guidance, a small catheter is placed through the skin and into the fluid collection to provide drainage to an outside container.
  • Ablation: Ablation is performed to remove unwanted tissues. For this procedure, either a high-energy material (such as laser energy) or a medication is injected into the tissue. During the following several days, the target cells die and are removed by normal body processes.
