When the Philippine College of radiology was established in 1948, there was only a handful of Filipino Radiologists. This was the period when Manila was being slowly rebuilt from the devastation brought about by World War II. At that time they call the organization, Philippine Radiological Society (PRS).  It is formed by the “ Magnificent  Seven”. The first PRS Constitution and by-laws were drafted.  In 1968 Dr. Federico Principe, together with the remaining members of the Magnificent 7 and other young remaining radiologists, successfully block a bill in Congress seeking to liberalize the acquisition of x-ray machines and professionalize x-ray technicians. In August 21, 1970, a new Constitution and by-laws change the name of the Philippine Radiological Society (PRS) to Philippine College of Radiology (PCR).

The decade of the ‘70s saw the major development of the Philippine Radiological Society. With the new name of the organization, Philippine College of Radiology, a new logo, designed by Drs. BienvenidoLapuz and EdmundoVillacorta and executed by an artist was formed in 1970.  The logo was considered a sign of peace, with the theme, “Medical Radiology for the Health of Mankind in Time of Peace.”

In My 29, 1971 the first oral examinations for certification in Radiology was held at the St. Luke’s Hospital in Quezon City by the newly formed Board of Examiners.    A new Code of Ethics was drafted by Dr. Hilario Zialcita and included in the constitution  in 1974 by Dr. Hilario Zialcita. The creation of the PCR gave way to the admission of more eligible members as Fellows.  By 1971, the PCR membership had grown from seven to about a hundred.

Several organizations had been formed by members all over the country.  The Northern and Central Luzon Chapter was formed in 1980 with Dr. Roberto Legaspi as president.  The Mindanao-Sulu chapter was formed in 1981 with Dr. Jose Gantioqui as president.  The Constitution and by-laws were corrected by Dr. Ronaldo Asuncion to conform with the SEC requirements.  The membership has grown to 239 in 1985. In September 1, 1982, the first PCR foundation day was celebrated and in October 29, 1982, PCR secretariat  Office was inaugurated.

The growing members initiated more  exciting exchanges in notes in radiology as the years go by.  Film reading sessions, difficult cases were discussed and lectures were given.  In 1983 a mid year post graduate symposium was started by Dr. HonoratoPiedad.  These scientific meetings served as a formal venues for exchanging notes and knowledge on trends in the specialty.  The first Scientific meeting of the section of Radiation Oncology was held.  In 1984 the specialty societies of Ultrasound and of Radiation Oncology were formally organized.In 1991, the PCR constitution underwent amendments to expand the growing membership categories.

In February 23, 1996, the PCR constitution and by-laws were amended during the  annual convention; amendments to the Code of Ethics are also proposed to address the changing needs and practices in Radiology.  The PMA acknowledged PCR as one of the only 8 specialty societies.

In 1997 the PCR Board of Directors approved the Revised Criteria for accreditation of Residency Training in Radiology.  The Residency training council ( RTC), a new PCR body   composed of all training officers of accredited hospital, was formed.

Today  2014,  the total members of the PCR is 1,428 and still counting every annual convention.

PCR is composed of several chapters: The Central Northern Luzon. Southern Luzon, Visayas -Northern Mindanao and Southern Mindanao. There are 5 subspecialty societies. The ultrasound Society, CT-MRI Society, Philippine Radiology Oncology Society, PSVIR and DBISP.
