PET Quality Control, Corrections and Processing (Slides)

Pdf Summary

This document is Module 3b of Part 2 of an educational course on PET (Positron Emission Tomography). The module covers topics related to PET quality control, corrections, and processing. The module includes learning objectives, an outline, and information on various aspects of PET imaging.<br /><br />The document discusses the physical differences between SPECT (Single Photon Emission Computed Tomography) and PET, highlighting the higher system sensitivity and resolution of PET. It explains the four types of PET photon events - singles, scatter, randoms, and trues.<br /><br />The basics of cardiac PET acquisition are explained, including the different types of acquisition methods - static, gated, and dynamic. It also details the processes of transmission imaging and emission reconstruction, including the use of iterative algorithms and post-reconstruction filters.<br /><br />The document also explains the concept of time-of-flight reconstruction and its advantages in improving image quality. It discusses the importance of a high-quality transmission scan for accurate attenuation correction.<br /><br />The module includes information on flow models used in PET, such as the single tissue compartment model and the net retention model. It also provides guidance on quality control measures for flow studies, including the inspection of bolus timing and finding the blood pool ROI.<br /><br />The use of Rate Pressure Product (RPP) as a quality control tool to correlate with blood flow is explained. The document emphasizes the importance of diligent quality control steps to ensure accurate results in flow studies.<br /><br />References to important research papers on PET imaging and quantification of myocardial blood flow are provided at the end of the document.<br /><br />In summary, this module provides a comprehensive overview of various aspects of PET quality control, corrections, and processing techniques.
