Positron Emission Mammography
Positron emission mammography (PEM) is a nuclear medicine imaging modality used to detect or characterise breast cancer. Mammography typically refers to x-ray imaging of the breast, while PEM uses an injected positron emitting isotope and a dedicated scanner to locate breast tumors. Scintimammography is another nuclear medicine breast imaging technique, however it is performed using a gamma camera. Breasts can be imaged on standard whole-body PET scanners, however dedicated PEM scanners offer advantages including improved Image resolution, resolution. PEM is not recommended for routine use or for breast cancer screening, in part due to higher radiation dose compared to other modalities. Compared to breast MRI, PEM offers higher Sensitivity and specificity, specificity. Specific indications can include "high-risk patients with masses > 2 cm or aggressive malignancy and serum tumor marker elevation". Fludeoxyglucose (18F), 18F-FDG is the most common radiopharmaceutical used for PEM. ...
