Associate Professor of Clinical Radiology and Biomedical Imaging; Radiology Director for Male Interventional HealthI am a board-certified Interventional Radiologist, which means I perform image-guided minimally invasive surgical procedures. These procedures are done by passing a specialized needle or catheter into a small hole in the skin, and from there I use radiographic, ultrasound, or CT-scan guidance to steer my instruments through blood vessels or soft tissues into the organ that I wish to treat. Almost every procedure can be done with IV sedation medication alone, so the patient does not need general anesthesia. Most patients usually can return home the same day with only a small bandage on, and they can often can go back to their normal activities after only a day or two of recovery at home. Watch a video with Dr. Raj Ayyagari>>I perform procedures in every part of the body, but I specialize in some remarkable minimally invasive procedures that are available to treat problems that patients have in their urinary and reproductive organ systems, problems that can severely impact quality of life or even life expectancy. These procedures can treat such problems successfully and safely, while allowing patients to avoid more invasive surgery.Prostatic artery embolization (PAE) is a remarkable procedure that is a safe and highly effective yet minimally invasive outpatient procedure that shrinks the prostate dramatically. This helps older men with benign prostatic hyperplasia (BPH) regain the ability to urinate normally again, without having to go through more invasive surgeries like a TURP (Trans-Urethral Resection of Prostate) or prostatectomy. This is truly a revolutionary procedure that has helped many men regain control of their lives, after suffering from what can become a severe medical condition that controls one's life.For patients with concerns for prostate cancer, we are one of the few centers in the country that perform MRI-guided prostate biopsies through the skin (the "perineum") instead of going through the rectum (as is done with standard prostate biopsies). This technique allows us to directly target specific areas of concern in the prostate under direct imaging guidance, while avoiding much of the infection risk that comes with performing prostate biopsies via the rectum.We are now one of a handful of centers in the country that perform a procedure called MRI-guided prostate cancer ablation. This is a minimally invasive technique performed via the urethra that allows us to treat prostate cancer without creating any incisions, often permitting the patient to return home the same day. The procedure is an excellent option for patients who are not necessarily good surgical candidates, and can be performed in selected patients after a thorough evaluation and conversation with both the a urologist specializing in cancer treatment and the Interventional Radiology team.For both younger and older male patients with large dilated veins in their scrotum, a common problem known as a varicocele, I also perform a safe and highly effective and minimally invasive outpatient procedure called embolization that closes these veins and shrinks them down. This procedure is a way to treat the pain, cosmetic problems, or even concerns for fertility (ability to have children) that can plague patients with this condition.

Professor of Radiology & Biomedical Imaging and Medical Oncology; Vice Chair for Clinical Research, Radiology & Biomedical Imaging; Section Chief, Interventional RadiologyDr. David C. Madoff is Professor of Radiology & Biomedical Imaging and Medical Oncology at Yale School of Medicine. His current administrative roles are Vice Chair for Clinical Research and Section Chief of Interventional Radiology. Dr. Madoff earned his B.A. from Emory University and his M.D. from the University of Pittsburgh. He completed both his internship in Internal Medicine and residency in Radiology at SUNY at Stony Brook and his fellowship training in Vascular and Interventional Radiology at The University of Texas MD Anderson Cancer Center. Dr. Madoff achieved Board Certification in Diagnostic Radiology from the American Board of Radiology in 2000 and attained his Certificate of Added Qualifications in Vascular and Interventional Radiology in 2002. He was a faculty member in the Section of Interventional Radiology at MD Anderson Cancer Center in Houston, Texas for a decade before joining New York-Presbyterian Hospital/Weill Cornell Medical Center in 2011. While at Weill Cornell, Dr. Madoff served as Division Chief of Interventional Radiology from 2011 to 2015 and Vice Chair for Academic Affairs from 2015 to 2019. He moved to Yale in July, 2019.Dr. Madoff has a strong background in clinical care and has treated many patients with complex oncological problems. His clinical interests are wide-ranging, and have included visceral vascular, hepatobiliary and genitourinary interventions, various embolotherapy and percutaneous biopsy techniques and many specialized therapies within the realm of Interventional Oncology. In particular, Dr. Madoff is world-renowned for his work on preoperative portal vein embolization, a technique used to improve the safety of major hepatic resection. This technique is based on the liver's ability to regenerate and has been used in patients with primary and metastatic hepatobiliary cancer to increase the size of the anticipated liver remnant before surgery. Without this procedure, many patients with potentially resectable disease would not be eligible for curative resection.Dr. Madoff is a leader in academic Interventional Radiology and has been an invited speaker at numerous national and international meetings. He authored or co-authored over 160 peer-reviewed scientific articles, has written more than 30 book chapters and served as co-editor of four textbooks including Venous Embolization of the Liver: Radiologic and Surgical Practice (2011), Clinical Interventional Oncology (2014) and Interventional Radiology: Fundamentals of Clinical Practice (2019). Dr. Madoff served as Deputy Editor-in-Chief for the Journal of Vascular and Interventional Radiology from 2007 to 2010 and Deputy Editor for Radiology from 2012 to 2017.
