BACKGROUND: In Spain, nuclear cardiology (NC) procedures represent the second most frequently performed studies in nuclear medicine (NM) centers. METHODS: 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. RESULTS: Data on 40,161 patients from 42 centers were collected. The responding public centers served 39% of Spain´s population. The estimated NC activity for public hospitals was 2 studies/1,000 population/year. Of all the NC procedures, 69% were SPECT myocardial perfusion imaging (MPI), 17% equilibrium ventriculography, 12% 18F-FDG PET, 1.3% first pass ventriculography, and <1% innervation and amyloidosis imaging, respectively. The most frequent NC study was a 99mTc tracer, exercise, 2-day MPI ECG-gated SPECT ordered by a cardiologist for diagnosis in an outpatient with 21 days of mean waiting time, the stress phase being supervised by both a cardiologist and a NM physician, with a NM physician writing a complete report. CONCLUSIONS: A major challenge for NC in Spain is the gradual adoption of high-sensitivity, low-dose-dedicated cardiac SPECT cameras and the broadening of cardiac PET utilization with more cameras, and the availability of MPI tracers alongside the viability/inflammation setup.

La gated-SPECT de perfusión miocárdica ha representado, desde su introducción hace algunos años, una mejora técnica muy importante dentro de las exploraciones de cardiología nuclear que se utilizan en el diagnóstico de la enfermedad coronaria. Actualmente es la exploración más utilizada, pues permite la valoración simultánea de la perfusión miocárdica y la función ventricular, tanto en condiciones de reposo como su respuesta al esfuerzo, aportando información de gran interés diagnóstico y también pronóstico. Se discuten los criterios diagnósticos de esta exploración en la cardiopatía isquémica, tanto aguda como crónica, las mejoras específicas aportadas por la gated-SPECT, así como las situaciones clínicas en que esta exploración es especialmente útil (AU)
Since its introduction some years ago, myocardial perfusion gated SPECT has been seen as a very important technical advance in the nuclear cardiology explorations used to diagnose coronary artery disease. Today, it is the most frequently used technique because it enables myocardial perfusion and ventricular function to be assessed simultaneously, both at rest and stress, thereby providing extremely useful diagnostic as well as prognostic information. This article discusses the criteria used for diagnosing acute and chronic ischemic cardiopathy, the specific advantages offered by gated SPECT, and the clinical situations in which this technique is particularly useful (AU)
