In Spain, nuclear cardiology (NC) procedures represent the second most frequently performed studies in nuclear medicine (NM) centers. The NC Working Group of the Spanish Society of Nuclear Medicine and Molecular Imaging invited NM departments across the country to answer an online questionnaire regarding 2014 activity. Data on 40,161 patients from 42 centers were collected. The responding public centers served 39% of Spain´s population.
