DIFI was formed in 2002 as the first standalone nuclear medicine center in India. It has since grown to include three diagnostic centers in Delhi, one in Lucknow, and plans to open a new center in Gurgaon. DIFI performs around 1500 scans per month across its centers and offers over 48 diagnostic tests using state-of-the-art equipment like PET-CT and gamma cameras. It aims to be the preferred choice for patients and doctors by adhering to high quality standards and fast turnaround times.
