Diagnostic Accuracy of Positron Emission Mammography with 18F-fluorodeoxyglucose in Breast Cancer Tumor of Less than 20 mm in Size
Objective(s): To investigate the diagnostic accuracy of positron emission mammography (PEM) and positron emission tomography/computed tomography (PET/CT) for small breast tumors of less than 20 mm in size.Methods: The study was conducted on a total of 100 subjects (i.e., 50 patients with pathologically proven breast cancer and 50 normal cases of medical screening). The total number of tumors wa...
متن کاملSoftware Tools for Breast Cancer Detection in Positron Emission Mammography Images
Positron Emission Mammography (PEM) is a novel imaging technology utilizing a dedicated Positron Emission Breast scanner. Two detectors in a configuration that resembles a conventional mammography (MG) machine cover a 250x120x200 mm3 volume, yielding 3D images of the breast, which is fixated between the detectors, but not compressed. The procedure depends on the administration of a radioactive ...
متن کاملPositron Emission Mammography (PEM): A Promising Technique for Detecting Breast Cancer
I. ABSTRACT We are developing a high specificity technique for detecting the increased metabolic rate of breast tiiinours. The glitcose analog FDG is known to concentrate in breast tiinlours rendering them easily detectable in conventional PET scans. Since PET is a relatively expensive imging technique it has not been used routinely in the detection of breast cancer. Positron emission mtnrnogra...
متن کاملComparison of Diagnostic Performance of Three-Dimensional Positron Emission Mammography versus Whole Body Positron Emission Tomography in Breast Cancer
Objective To compare the diagnostic performance of three-dimensional (3D) positron emission mammography (PEM) versus whole body positron emission tomography (WBPET) for breast cancer. Methods A total of 410 women with normal breast or benign or highly suspicious malignant tumors were randomized at 1 : 1 ratio to undergo 3D-PEM followed by WBPET or WBPET followed by 3D-PEM. Lumpectomy or maste...
متن کاملHigh-resolution fluorodeoxyglucose positron emission tomography with compression ("positron emission mammography") is highly accurate in depicting primary breast cancer.
We sought to prospectively assess the diagnostic performance of a high-resolution positron emission tomography (PET) scanner using mild breast compression (positron emission mammography [PEM]). Data were collected on concomitant medical conditions to assess potential confounding factors. At four centers, 94 consecutive women with known breast cancer or suspicious breast lesions received 18F-flu...
