MO-E-217A-01: Contrast-Enhanced Spectral Mammography - Physical Aspects and QA
Medical Physics
|May 19, 2017
Summary
Dual-energy contrast-enhanced mammography (CE-MM) offers new insights into tumor angiogenesis and can detect cancers missed by standard mammography. A robust quality assurance program is essential for this advanced imaging technique.
Area of Science:
- Radiology and Medical Imaging
- Biomedical Engineering
Background:
- Digital mammography is a standard screening tool.
- Contrast-enhanced mammography (CE-MM) utilizes iodinated contrast agents to improve lesion detection.
Purpose of the Study:
- To outline the current status of dual-energy contrast-enhanced digital mammography (DECE-MM).
- To identify critical operational aspects for evaluation and monitoring.
- To propose a quality assurance (QA) program for DECE-MM systems.
Main Methods:
- Discussion of dual-energy contrast imaging principles.
- Description of tools and techniques for performance assessment.
Main Results:
- Key factors for digital mammography image quality (noise, linearity, output consistency, artifacts) remain crucial.
- Image registration is vital for overall image quality.
- New QA challenges include maintaining breast compression and calibrating for iodine quantification.
Conclusions:
- DECE-MM provides novel information on tumor angiogenesis and can detect cancers not visible on standard mammography.
- This modality may improve the assessment of disease extent.
- Medical physicists must understand the physics of image quality, and a comprehensive QA program is necessary to realize the full potential of DECE-MM.

German physicist Wilhelm Röntgen (1845–1923) was experimenting with electrical current when he discovered that a mysterious and invisible "ray" would pass through his flesh but leave an outline of his bones on a screen coated with a metal compound. In 1895, Röntgen made the first durable record of the internal parts of a living human: an "X-ray" image (as it came to be called) of his wife’s hand. Scientists worldwide quickly began their own experiments with...
