On the web
Overview
Dr. Raghuram “Ram” Posham is a board certified vascular and interventional radiologist at Columbia University Irving Medical Center. He is an assistant professor of radiology and an attending physician at NewYork-Presbyterian Hospital. Dr. Posham specializes in minimally invasive, image-guided treatments that reduce pain, shorten recovery time, and allow patients to return to normal life as quickly as possible. He treats a wide range of conditions, from cancer to men's and women's health.
A key focus of Dr. Posham’s practice is men’s health, including treatment for benign prostatic hyperplasia (BPH), or enlarged prostate, which can cause urinary symptoms that interfere with daily life. He also treats varicoceles, a common condition that can cause discomfort or fertility concerns, as well as erectile dysfunction due to blocked pelvic arteries. Using advanced imaging and catheter-based techniques, Dr. Posham offers effective, nonsurgical solutions tailored to each patient’s needs.
Dr. Posham is actively involved in academic research and has made significant contributions to the field of interventional radiology. His research interests encompass trans-radial arterial access, peripheral arterial disease interventions, and complex inferior vena cava (IVC) filter retrieval techniques. Through numerous peer-reviewed articles in prestigious medical journals, he has enhanced the understanding and practice of interventional radiology, earning recognition for his dedication to advancing medical knowledge. His contributions to the medical community have been recognized with various honors, including the Editor's Award for Outstanding Clinical Research at the Society of Interventional Radiology (SIR) 2017 Annual Scientific Meeting and the Burton Drayer Prize in Radiology and Imaging from the Icahn School of Medicine at Mount Sinai.
Dr. Posham served as chief resident for the Integrated Interventional Radiology Residency at Mount Sinai Hospital. He holds an MD with Distinction in Research from the prestigious Icahn School of Medicine at Mount Sinai. Additionally, he earned an MPA with a specialization in health services management from New York University's Robert F. Wagner Graduate School of Public Service, and a BA in economics, graduating magna cum laude from New York University's College of Arts and Science.
