In the bustling medical corridors of New Delhi, a young doctor named Harsh Mahajan once looked at an ordinary X-ray film and imagined something far more powerful—images that could peer deep into the living body without a single incision. Born in New Delhi, he completed his MBBS at Maulana Azad Medical College and earned his MD in Radiology from the Postgraduate Institute of Medical Education and Research (PGIMER) in Chandigarh. A brief stint at AIIMS followed, but his curiosity was already fixed on a new frontier: magnetic resonance imaging.

In 1987 a Rotary International Scholarship took him to the MD Anderson Cancer Center in Houston, Texas. There he immersed himself in the still-emerging world of MRI. When he returned to India, the technology was almost unknown. Most large government hospitals did not yet have a scanner. In 1991, with determination that bordered on audacity, he set up one of the country’s first private MRI centres. Colleagues raised eyebrows. “It is too expensive, too complicated,” some said. Mahajan simply replied, “Patients should not have to wait for the future. We can bring it to them now.”

That single centre grew into Mahajan Imaging, a network of advanced diagnostic facilities across Delhi that partnered with major hospitals such as Sir Ganga Ram, BLK and Fortis, and even entered public-private partnerships with government institutions. He introduced functional MRI, PET-CT, nuclear medicine and other cutting-edge techniques long before they became standard. Over 250 radiologists trained under him. He served as Director of Nuclear Medicine and Bone Densitometry at Sir Ganga Ram Hospital, Honorary Radiologist to the President of India, and Honorary Consultant to the International Atomic Energy Agency in Vienna.

As National President of the Indian Radiological and Imaging Association, he pushed for higher standards and wider access. He lectured across continents—from MIT in Boston to conferences in Japan, China and Europe—always insisting that technology must serve the patient, not the other way around. “An image is only as good as the care that follows it,” he would tell young doctors. “Diagnosis without compassion is incomplete.”

In 2002 the nation recognised his pioneering work with the Padma Shri. Beyond the clinic he has remained deeply involved in social causes, chairing Tamana, an organisation that runs schools for children with multiple challenges, and supporting initiatives that provide free cardiac surgery to underprivileged children.

From a young radiologist who refused to wait for institutional timelines to a leader who placed advanced imaging within reach of ordinary Indians, Harsh Mahajan’s journey is one of quiet revolution. He did not invent the MRI machine, but he made certain that its life-saving power arrived in India earlier, travelled farther, and touched more lives than anyone thought possible.
