Positron emission mammography (PEM) is a newer imaging test of the breast that combines some aspects of a PET scan and a mammogram. PEM uses the same type of radioactive tracer injected into the blood as a PET scan. The breast is then lightly compressed while the images are taken, as with a mammogram.

2018年4月26日 · The diagnostic breast imaging tool Positron Emission Mammography (PEM) uses short-lived positron-emitting isotopes to generate high-resolution tomographic images of cancer within the breast. PEM works by using an intravenous injection of the radiopharmaceutical 2-deoxy-2-( 18 F)fluoro-D-glucose, abbreviated as 18F-FDG.

Positron emission mammography (PEM) is a nuclear medicine imaging modality used to detect or characterise breast cancer. [1] 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.

Background: Positron Emission Mammography (PEM) is an imaging technique which is increasing focuses on imaging the chest instead of imaging the whole body. The aim of this study was to conduct a systematic review of the clinical efficacy and ...

Positron emission mammography (PEM) is new technology that allows imaging specifically for the breast. When compared with conventional PET and PET/CT, PEM has better spatial resolution (∼1.5 mm), requires a lower radiotracer dose (3–5 mCi), and has a shorter acquisition time (2–4 minutes) and lower cost.

2020年8月18日 · Background: Positron Emission Mammography (PEM) is an imaging technique which is increasing focuses on imaging the chest instead of imaging the whole body. The aim of this study was to conduct a systematic review of the clinical efficacy and coste-ffectiveness of PEM technology, as compared with PET, as a diagnostic method used for breast ...

Positron emission mammography (PEM) is a new imaging modality that has higher resolution than PET-CT and can be per-formed on patients unable to have an MRI scan. PEM uses a pair of dedicated gamma radiation detectors placed above and below the breast and mild breast compression to detect coincident gamma

Positron emission mammography (PEM) is a new imaging modality that has higher resolution than PET-CT and can be performed on patients unable to have an MRI scan. PEM uses a pair of dedicated gamma radiation detectors placed above and below the breast and mild breast compression to detect coincident gamma rays after administration of fluorine-18 ...

2022年9月13日 · Positron emission mammography (PEM) is particularly useful when other imaging scan results are indeterminate. It has a useful complementary role to mammography,...

Positron emission mammography (PEM) uses two opposing gamma-ray imagers and limited-angle tomography techniques to image radiotracer distributions within the breast. Due to their smaller size and closer proximity to the source, dedicated PEM cameras can provide better spatial resolution and count sensitivity than whole-body positron emission ...
