I am an interventional radiologist, a physician who uses x-ray, CT, ultrasound, and MR images to perform procedures less invasively. I am Chief of the Interventional Radiology Service in the Department of Radiology and also director of Memorial Sloan Kettering’s new Center for Image-Guided Intervention (CIGI). At CIGI, multiple imaging modalities and multiple disciplines will be combined to develop and apply new image-guided cancer therapies.
Interventional radiology is an increasingly common approach to treating cancer. We use images to see the tumor and the blood vessels that supply it, to help guide our minimally invasive tools to the site of the tumor, and to perform several different diagnostic and therapeutic techniques. Patients who undergo interventional radiological procedures do not need a large incision; they can often be “consciously sedated” rather than undergo general anesthesia, and in many cases their procedures are less risky and their recovery times shorter than they would be with traditional surgery.
My particular area of interest is treating tumors with thermal ablation — a technique in which we use imaging to guide a needle to a target tumor and then destroy it through the application of heat (radiofrequency ablation) or extreme cold (cryoablation). I treat kidney, liver, lung, and bone cancers with these procedures. I also perform hepatic artery embolization, a technique in which we inject particles into the main blood vessel that supplies a tumor to cut off its blood supply.
Some of my current research projects involve evaluating a new ablation tool called “irreversible electroporation” (NanoKnife); using a CT-guided clinical robot to perform procedures more accurately; using PET images to monitor the health of patients who have undergone ablation; and studying ways to boost the immune system’s reaction to cancer cells after tumor ablation.
