Summary

With the aging of the population and the acceleration of urbanization process, the number of cardiovascular diseases in China continues to increase, with one in five adults suffering from cardiovascular disease. The mortality rate of cardiovascular disease in China is also on the rise, and cardiovascular disease deaths are now the leading cause of death among urban and rural residents, mainly due to ischemic heart disease (IHD). Ischemic heart disease is the damage to the heart muscle caused by changes in the coronary cycle that cause an imbalance between coronary blood flow and the needs of the heart muscle.This project obtains MBF and CFR through 13N-NH3PET cardiac blood flow perfusion rest and load imaging, and explores the diagnostic value of PET imaging to CMVD. In summary, this project will obtain myocardial blood flow (MBF) and myocardial blood flow reserve (CFR) through 13N-NH3 PET cardiac blood flow perfusion rest and load imaging, explore the diagnostic value of PET imaging for CMVD, and promote the widespread application of absolute quantification of myocardial blood flow in China.

Conditions

  • PET / CT
  • Coronary Microvascular Disease

Interventions

DIAGNOSTIC_TEST

13N-NH3 PET cardiac blood flow perfusion rest and load imaging

Immediately after the bedside injection of 13N-NH3 370 MBq, dynamic 2D collection of heart images 10 min, scanning 1 bed; , a total of 6 min), 3min bedside injection 13N?NH3 370-540 MBq immediately after the dynamic 2D collection of heart image 10 min. Both rest and load imaging are corrected for CT attenuation. Image reconstruction is carried out by the method of maximum expectation of an ordered subset, the dynamic image is divided into the early phase of the first 2 min and the late phase of the last 8 min, the captured image is replayed (VIP replay) of the volume image protocol and the gated data is reconstructed.
