Interventional Radiology

Houston Methodist’s radiologists provide minimally-invasive radiology treatments for non-vascular conditions (i.e., conditions not involving blood vessels, such as questionable masses). Early detection and evaluation is made possible via non-vascular interventional radiology to help our patients be fully informed about the need and options for further treatment, if necessary. Our board-certified radiologists are highly skilled and trained, and committed to address your specific condition through the use of techniques like fine needle aspiration (FNA) biopsies and tumor ablation.

Fine Needle Aspiration
A fine-needle aspiration (FNA) biopsy is a minimally-invasive procedure performed through an insertion in the skin that can help determine the cancerous status of a lymph node mass or nodule that has been detected by your physician. FNA biopsies are generally performed on easy-to-reach areas like the breast, thyroid gland and lymph nodes in the neck, groin and armpit. An endoscopy, which  is a procedure that uses a light and camera attached to a flexible tube can be used to help guide an FNA to harder-to-reach areas in the chest or stomach. FNA biopsies allow our radiologists to make an early assessment without the need for more invasive procedures.
Tumor Ablation
Houston Methodist physicians use ablation therapy to destroy tumors or abnormal tissue. A flexible probe is inserted through the skin and then guided by imaging technology using energy beams to destroy or at least injure the tumor or tissue with extreme heat (radio frequency ablation) or extreme cold (cryoablation). This procedure is beneficial because it targets the unhealthy tissue and has fewer risks and less discomfort than procedures that involve open surgery, resulting in a faster recovery time for patients.
