How long has nuclear medicine been used?
Nuclear medicine has a complex and multifaceted heritage. Its origins stem from many scientific discoveries, most notably the discovery of x-rays in 1895 and the discovery of “artificial radioactivity” in 1934. The first clinical use of “artificial radioactivity” was carried out in 1937 for the treatment of a patient with leukemia at the University of California at Berkeley. A landmark event for nuclear medicine occurred in 1946 when a thyroid cancer patient’s treatment with radioactive iodine caused complete disappearance of the spread of the patient’s cancer. This has been considered by some as the true beginning of nuclear medicine.
