Study Notes
SPECT vs Planar Imaging
- SPECT provides 3D images of the body's internal organs and structures, allowing doctors to see the distribution and function of tissues and organs in more detail than planar images.
SPECT Used To Diagnose
- SPECT can help diagnose various medical conditions impacting the heart, brain, bones, and lungs, such as:
- Cardiac problems: Coronary artery disease, heart attacks, and cardiomyopathy
- Brain disorders: Epilepsy, Alzheimer's disease, stroke, and dementia
- Bone diseases: Osteoporosis, arthritis, and bone infections
- Lung conditions: Pulmonary embolism, pneumonia, and lung cancer
How SPECT Machines Capture Images
- SPECT scans use a gamma camera that rotates around the patient.
- The camera detects gamma rays emitted from radioactive tracers that have been injected into the patient's bloodstream.
- By collecting data from different angles, the machine reconstructs 3D images of the organs and tissues.
SPECT-CT Hybrid Imaging
- SPECT-CT fusion combines the anatomical information from CT scans, revealing the precise location of abnormalities, with the functional data provided by SPECT, showing how organs and tissues function.
- This fusion improves the accuracy and clarity of the images for better diagnosis and treatment planning.
SPECT vs Standard CT
- SPECT focuses on visualizing the functionality of organs and tissues by detecting radioactive tracers.
- Standard CT focuses on providing anatomical details of the body's structure using X-rays.
- While both provide valuable information, the combination of SPECT and CT offers comprehensive insights into patient health.
