DOI: 10.1007/s00259-025-07196-0

Abstract: To determine the most important patient factors influencing quantitative MBF and to report the lower (LRL) and upper (URL) reference limits for 13N-ammonia positron emission tomography (PET) myocardial perfusion imaging (MPI). Patients who underwent 13N-ammonia… read more here.

DOI: 10.1093/ehjci/ehaa946.0289

Abstract: Positron emission tomography myocardial perfusion imaging (PET MPI) is a robust and excellent tool for assessing ischemia. So far, however, no methodology has been established to distinguish truly reduced MFR due to microvascular dysfunction or… read more here.

DOI: 10.3389/fmed.2025.1649175

Abstract: Objective Absolute quantification of myocardial perfusion and coronary flow reserve (CFR) with positron emission tomography (PET) has demonstrated diagnostic and prognostic value in patients with coronary microvascular dysfunction (CMD). However, no studies have compared magnetic… read more here.

DOI: 10.3390/molecules28114517

Abstract: [13N]Ammonia is one of the most commonly used Positron Emission Tomography (PET) radiotracers in humans to assess myocardial perfusion and measure myocardial blood flow. Here, we report a reliable semi-automated process to manufacture large quantities… read more here.
