A questionnaire was sent to all departments of nuclear medicine in Denmark (n=20) asking for details of myocardial perfusion imaging (MPI), including the number of patients examined each year from 1997 to 2001 and the current clinical and technical practice. All (100%) departments replied, and the survey thus covers all MPI performed in Denmark during the period in question. The number of MPI studies (examined patients) was 2,531 in 1997 (0.47 MPI/1,000/year) and 4,961 (0.93 MPI/1,000/year) in 2001, which is a doubling in activity in 5 years. Nineteen (95%) of the Danish departments performed MPI in 2001, and 14 (74%) of these reported that activity had increased over the past 5 years. MPI activity was unevenly distributed between hospitals and regions. In 2001, the university hospitals in the central Copenhagen region (capital) accounted for the highest MPI activity (2.00/1,000/year), while the non-university hospitals in general had the lowest activity rate (0.73/1,000/year). The most pronounced increment found in the period was observed in the university hospitals outside Copenhagen, where activity increased by 300% from 0.44/1,000/year in 1997 to 1.33/1,000/year in 2001. All departments providing MPI used tomographic acquisition technique and all departments used technetium tracers. The more sophisticated techniques of MPI - gated acquisition, attenuation correction and iterative reconstruction - were used in 74%, 32% and 42% of departments, respectively. The stress mode in perfusion studies was dipyridamole/adenosine in 76%, exercise in 18% and dobutamine in 6%. Despite these encouraging figures, MPI activity for 2001 remained well below what is recommended by other national and international societies. The anticipated further increase in nuclear cardiology is encouraging, but the nuclear medicine community needs to address the issues that prevent it from keeping up with demand. In general, the restricted camera time and the limited number of trained personnel explain the excessive waiting lists in Denmark.
