Presentation of the ClearPEM-Sonic mammography scanner ClearPEM-Sonic

2 Breast cancer:  The most frequent cancer in women  One in nine women has breast cancer in her life X-ray mammography  Standard in breast cancer diagnosis  Based in structural tissue changes  High rate of false-positive  Less reliable in dense breasts  Less reliable in dense breasts  false negatives Breast cancer

3 PET mammography X-ray mammography PET mammography PET and breast cancer PET/FDG has good sensitivity in breast cancer diagnosis Radioactive tracer FDG : glucose associated to positron emitter F-18 Glucose has strong affinity to cancer cells PEM Scanner Positron Emission MammographyPositron Emission Mammography PET equipment dedicated to breast and axila examsPET equipment dedicated to breast and axila exams Good spatial resolution ( ~ mm)Good spatial resolution ( ~ mm) Good sensitivityGood sensitivity

4  New technology based in fast crystals (LSO) and avalanche photodiodes (APD) associated to low-noise integrated electronics  The new electronics has the highest integration density available worldwide: compact detectors with DoI capability  Scanner with excellent spatial resolution (1.3 mm)  Integration with ultra-sound probe with elastography from company Supersonic Imagine.
