PhD student in cardiac positron emission tomography (PET).
Last year, for the first time, our group presented a method on how to quantify mitral regurgitation using cardiac-PET. Article: ejnmmires.springeropen.com/articles/10.... #ISRVT25 #CardiacPET#MitralRegurgitation
Quantitation of mitral regurgitation using positron emission tomography - EJNMMI Research
Background Cardiac positron emission tomography (PET) offers non-invasive assessment of perfusion and left ventricular (LV) function from a single dynamic scan. However, no prior assessment of mitral ...

When imaging the flow of radioactive water through the central circulation, a lot more than myocardial perfusion can be calculated. My research focuses on how we can further utilize and refine the vast amount of information that is available from such images #ISRVT25

Oxygen-15 has a short half-life (122 s) which yields a low radiation dose to the patient and allows for rest/stress imaging of the heart in the same session. However, you do need to be in a hurry when working with radioactive water! #ISRVT25

In oxygen-15 water PET, the radioactive tracer is injected simultaneously to starting the PET acquisition. This is known as dynamic PET imaging and allows us to follow rapid processes in the body #ISRVT25

Assessment of myocardial perfusion is an important task in cardiovascular imaging. The gold standard for non-invasive quantification of myocardial perfusion is positron emission tomography (PET) using radioactive water (labeled with the isotope oxygen-15). #ISRVT25
