Dr Semelka has written 350+ peer-reviewed articles in Radiology and 17 textbooks, including Health Care Reform in Radiology. He has been one of the most accomplished authors on safety, especially regarding medical radiation, patient information, overuse of imaging, NSF, and most recently GDD. He has been Director of MR services (Dec 1992- Sept 2017) and vice-Chair of Quality and Safety (Dec 1, 2007 – 2016) at the University of North Carolina. Presently he focuses on treating patients with Gadolinium Deposition Disease at his Medical Clinic in North Carolina.
Dr. Semelka has been one of the major forces in Radiology for 3 decades. He has been a leading researcher and practitioner in MRI, has pioneered and is the leading author worldwide on abdominal MRI, and is the radiologist with the broadest research, and publication record on safety in Radiology, having authored major works on informed consent, overuse of imaging, risk of cancer from CT and x-rays, nephrogenic system fibrosis, Gadolinium deposition in the brain on MRI, and most recently has pioneered in the medical literature the subject of Gadolinium Deposition Disease (GDD) and is presently the leading author on the subject. GDD is essentially a severe persistent disease secondary to the use of Gadolinium Based Contrast Agents (GBCAs) in individuals who often have normal kidney function.
Dr Semelka has had a profound international role in GDD, essentially being consulted by people from around the world and overseeing their treatment, from India to New Zealand, and every country in between. The majority are in the US, with Canada and the UK, and Europe as the other major centers for patient treatment. In many respects, Dr. Semelka has unofficially become the Protector Publicus (protector of the people) by focusing on the judicious and appropriate use of advanced imaging throughout the world. He is not the destroyer of imaging but rather the medical doctor with extensive knowledge and expertise to maximize diagnosis while maximizing safety for patients. No other physician or radiologist by global impact or by published expertise can claim this to this extent.

Tina is a recovering patient of GDD and knows by experience the devastation that heavy metal toxicity has on one's life. Having completed four years of DTPA chelation, following the Semelka protocol, she is making great strides in regaining her health and has made it a personal commitment to help others with GDD and other heavy metal illnesses. She is generous, encouraging and opens her home to GDD patients traveling for treatment.
