Study Guide II - Final Exam in PET
- Fundamental concepts
- How is a prompt event recorded?
- LOR
- Timing window
- Low Energy Threshold
- Coincident circuit
- PHA
- Prompt - Sinogram
- Basic concepts behind crystals - why is LYSO better than BGO?
- TOF
- Concept
- Calculate
- Result - SNR
- Consider the numerous components that effect resolution
- FOV center vs edge
- Bed - center vs edge
- Radial Elongation
- 2 vs 3D
- Scatter and Random
- 1/3 Beta Max
- Non-collinearity
- Localization of detectors
- Image reconstruction
- Components that effect contrast
- Patient motion
- Count density
- Tissue density
- Noise
- Type of lesion
- Imaging display
- PET QC
- Normalization
- Blank scans
- Acquisition modes - Where do they apply?
- Static - single bed
- Whole body
- Gated
- Dynamic
- AC of PET/CT
- Segmentation
- Mono vs poly energetic photons
- Scaling
- Consider normal and abnormal results when AC correction is applied
- Discuss the effects of deadtime in a PET scan
- Describe the problem
- Consider crystal application and how this should reduces the deadtime issue
- Imaging reconstruction
- Compare iterative to FBP
- Understand the IR process: OSEM and MLEM
Part II
- Clinical PET
- Pathophysiology of
- 18FDG
- 82RB
- 15O
- Na18F
- Review the other radiopharmaceutical used in oncology and compare them to FDG (is there an improvement in detecting disease?)
- Oncology
- Uptake
- The role of PET
- Primary tumor and evaluation of metastatic disease
- Identifying the surgical candidate (for a and b consider lung cancer)
- Application with patients that are on or going to be on chemotherapy
- After cancer has been reseeded how can PET be used to assess recurrence of disease
- What types of cancer should PET-FDG be used for
- PET procedure (general)
- Eyes to Thighs
- Head to Toe
- Single bed (brain)
- SUV
- Components that must be strictly considered when using SUV assessment in oncology
- When the patient has a follow-up exam, what needs to be considered?
- Neurology
- Know the details on how to complete a PET brain procedure
- What concerns are there when imaging the brain with FDG - brain uptake vs. disease vs. white and gray matter
- Up/down regulation
- Diseases:
- Application in Epilepsy
- Picks and AD
- Assessment with trauma
- Low vs high metabolic glioblastoma
- Cardiology
- Viability with FDG (procedure)
- Stress test with 82RB (procedure)
- Physiological states of the heart
- You do not have to calculate Sr breakthrough, but you should understand the concept
