Positron emission computed tomography (PET) offers high-quality cardiac imaging with accurate attenuation correction. This advanced technique is poised to become crucial in nuclear cardiology despite its high costs.

Area of Science:

  • Cardiology
  • Nuclear Medicine
  • Medical Imaging

Background:

  • Positron emission computed tomography (PET) provides high-resolution tomographic images of the heart.
  • Accurate attenuation correction is a key feature of PET imaging.
  • Various positron-emitting radionuclides (e.g., 11C, 13N, 15O, 18F) enable in vivo physiological and biochemical measurements.

Purpose of the Study:

  • To highlight the introduction and potential of Positron Emission Tomography (PET) in Japanese cardiology.
  • To discuss the capabilities of PET for cardiac imaging and physiological assessment.

Main Methods:

  • Utilizes positron emission computed tomography (PET).
  • Employs various compounds labeled with ultra-short lived positron-emitting radionuclides (11C, 13N, 15O, 18F).
