The utilization of intravenous contrast with mammograms introduces a functional element to imaging. This greatly improves the sensitivity of the examination, approaching sensitivity levels of Magnetic Resonance Imaging (MRI) in the detection of primary breast cancer. With increased sensitivity afforded by ...
METHOD AND MATERIALS In this institutional ethics approved prospective study, we compared the performance of contrast based digital mammography with magnetic resonance imaging on 70 female patients. Standard digital mammogram was done in the mediolateral oblique and craniocaudal projections followed by low ...
Retrospectively, the majority of the lesions were either occult or a 'minimal sign' on low-energy CESM images or the screening mammogram. CONCLUSION: Using CESM as a work-up tool for women recalled from screening carries low risk for the patient, while additionally detected tumour foci might ...
Abnormal breast tissue can be detected with CESM by administering intravenous iodinated contrast. This dissertation explains the way in which CESM works. Furthermore, the use of CESM in clinical practice is studied in women who have been referred after taking part in the national breast cancer ...
To evaluate the relationship of the extent and quantitative intensity of background parenchymal enhancement (BPE) on contrast-enhanced spectral mammography (CESM) with age, breast density, menstruation status, and menstrual cycle timing. This retrospecti
with different results. We calculated an AUC of 0.843 in the former projection and 0.755 in the latter projection and found a significant difference of enhancement intensity between two views, indicating that the former projections of contrast-enhanced images seemed to play a more important role in...
We describe a novel method for the calculation of endothelial permeability surface area product from dynamic contrast enhanced MRI. The technique uses iterative estimation to automatically decompose tissue residue function into intravascular and extravascular components, which are subsequently used to generate...
As well known, it is difficult to robustly achieve mammogram mass segmentation due to low contrast between normal and lesion tissues, as well as high density tissue interference in mammograms. Therefore, Spiking Cortical Model with biology background is introduced to achieve mammary-specific and mass...
There is, however, a problem with both the DBT and the common mammogram. Specifically, neither process can reliably discern the patterns of microcalcifications within the breast—some of which are indicative of ductal carcinoma in situ (DCIS) and some of which are benign. In general, these mic...
Image review may also be done in a volume rendering mode. In an example of this mode, the first image displayed is a standard mammogram calculated from the three-dimensional dataset84. Mean intensity projection, maximum intensity projection, or composite ray casting can be used for the calculatio...
