Diagnostic & Interventional Radiologist

Duan Li, MD

About Me

My dual expertise in body imaging and interventional radiology enables me to fill a distinctive position in the Radiology Department at Memorial Sloan Kettering Cancer Center. I am one of a very few in the department to combine diagnostic with interventional responsibilities. My hospital work reaches into three areas: performing basic diagnostic exams using ultrasound; performing interventional (IR) procedures and biopsies under the guidance of ultrasound, CT, and fluoroscopy; and doing intraoperative, image-guided procedures in the operating room.

When I joined the Memorial Sloan Kettering faculty in January 2008, the only ultrasound-guided biopsies performed were of the thyroid. Since then, I have extended this service to include biopsies of the abdomen, pelvis, musculoskeletal organs, and lymph nodes. I have also initiated a program of transvaginal ultrasound-guided biopsies. Ultrasound-guided biopsies often provide a safer, quicker, more-comfortable experience for the patient, with a quicker recovery time, than when CT and fluoroscope guidance is required.

I further use transvaginal and transrectal ultrasound to guide IR procedures in the operating room. I work closely with gynecologists in the operating room to rebuild the cervical canal in patients with cervical cancer, thereby facilitating pregnancy and monitoring of the uterus.

In the research realm, I am fine-tuning fusion techniques in which ultrasound, CT, and MRI images are correlated and superimposed one on top of the other to pinpoint lesions with great precision. I am also investigating the utility of elastography, which employs the principle that cancerous tissue is stiffer than normal tissue, with the end-goal of minimizing unnecessary biopsies. These techniques have useful implications in the operating room in providing guidance for tumor ablation, pelvic lymph node dissection, and prostate surgery.

Administratively, I am currently an active member of the Hepatobiliary Disease Management Team at Memorial Sloan Kettering and also serve on the Department of Radiology Research and Quality Assurance Committees. I also received the 2013 Clinical Excellence Award from the Department of Radiology for my work.  

Above all, I continue to seek ways to use radiology techniques in order to enhance patient comfort and well- being.

Insurance

Most major health insurers offer plans that include MSK as one of their in-network providers. If MSK is in-network, it means all our doctors are too. Medicaid and New York State Medicare also provide benefits for care at MSK.

Clinical Trials

As home to one of the world’s top cancer research centers, Memorial Sloan Kettering is typically involved in more than 900 clinical trials at a given time. Currently, clinical trials focused on the conditions I treat are enrolling new patients.
