What are our patients saying?

“Wonderful staff (Carole is the best) and Dr Ledezma was wonderful. He spent a full hour talking to me and my family about my sickness, my prognosis and the planned procedure. I left having full confidence in him and in his staff. I wish every doctor would be so through !”


Thank you for the great review!  We are very proud of our care team and when you are passionate about what you do, it is easy to provide great service.

Interventional Oncology

Interventional Oncology


Interventional oncology (IO) procedures provide minimally invasive, targeted treatments for cancer patients.  IO procedures form an integral part of the multi-disciplinary team (i.e. medical oncology, surgical oncology, radiation oncology, and interventional oncology) approach in the treatment of cancer and cancer-related disorders.

Image guidance is used in combination with the most current innovations available to treat cancerous tumors, while minimizing possible injury to other body organs.  Most patients having these procedures are outpatients or require a one night stay in the hospital.

  • Some of these therapies are regional, as when treating cancers involving several areas of the liver with chemoembolization or radioembolization.
  • Others are better classified as local, as when treating focal lesions in the kidney, liver, lung and bone with cryoablation (freezing), or microwave or radiofrequency ablation (heating).

In general, these techniques are reserved for patients whose cancer cannot be surgically removed or effectively treated with systemic chemotherapy. These procedures are also frequently used in combination with other therapies provided by other members of the cancer team.

CT-Guided Percutaneous Cryoablation For Early-Stage Renal Cell Carcinoma May Be Safe, Effective.

Renal and Urology News (1/8, Charnow) reports that research published online in Cardiovascular and Interventional Radiology indicated that “computed tomography (CT)-guided percutaneous cryoablation for early-stage renal cell carcinoma (RCC) is highly efficacious and has a favorable safety profile.” Investigators came to this conclusion after treating “134 patients with biopsy-proven RCC using CT-guided cryotherapy.”


Dr. Ledezma, our Interventional Radiologist is active in diagnosing and treating patients with Renal Cell Carcinoma using CT-guided cryotherapy.  If you are interested in being evaluated by Dr. Ledezma or have a patient that could benefit from it procedure, please contact him at 810-667-5744.

Who is the Interventional Radiologist?

The interventional radiologist is a medical doctor who has completed four years of study in radiology. The interventional radiologist is then eligible to take the board examination given by the American Board of Radiology. Following board certification, the interventional radiologist completes an interventional radiology fellowship training program. Today, there are more than 5,000 interventional radiologists in the US, mainly practicing in academic medical centers and in larger community hospitals. Interventional radiologists work closely with other physicians and play an important role on the treatment team.

We provide state-of-of the-art diagnostic and interventional radiology services in a timely and cost effective manner for our patients and do research to develop new technologies for the future.

Interventional radiology can be defined as a specialty where trained radiologists use various imaging techniques and modalities to guide percutaneous minimally invasive diagnostic and therapeutic procedures. The procedures are called percutaneous procedures because, as opposed to surgery, they are done through the skin using a needle stick or a small cut down technique. The procedures are usually simpler and safer, less traumatic, less painful, less invasive and in general as effective, and more cost-effective than comparable open surgical procedures.

Our Division Interventional Radiology is directed by Carlos Ledezma, M.D.
