Contrast-enhanced spectral mammography (CESM), an emerging digital mammography technology, has been approved by the U.S. FDA and put into clinical use in 2011. After intravenous iodine contrast agent, pairs of low-energy (LE) and high-energy images are acquired to generate the subtraction images...
Contrast-enhanced spectral mammography (CESM) has proven to be a beneficial tool for additional management and diagnosis of breast cancer in patients. Deep learning-based automated tools for analyzing CESM images and detecting abnormalities can be crucial in reducing the workload of radiologists. Even...
All patients were assessed by contrast-enhanced spectral mammography (CESM) (Fig. 3). The examina- tions elicited 21 (32.8%) patients were negative studies; however, the positive studies were among 1.6% showed benign-looking enhancing lesions, 4.7% revealed benign-looking non-mass enhancement,...
Although studies have showed that MRI has superior performance than some other techniques such as ultrasound or mammography, its efficacy in identifying axillary lymph node status is unsatisfactory [10, 11]. Dynamic contrast enhanced magnetic resonance imaging (DCE-MRI) can provide pharmacokinetic ...
Contrast-enhanced magnetic resonance imaging of breast lesions was reported in a preliminary study in 1986, and was shown to be more accurate than X-ray mammography and unenhanced MRI [153]. In the following years, various technical developments were described [154,155]. CE-MRI has since been...
Grating interferometry X-ray differential phase contrast imaging (GI-XDPCI) has provided enhanced imaging contrast and attracted more and more interests. Currently the low imaging efficiency and increased dose remain to be the bottlenecks in the engineering applications of GI-XDPCI. Different from the...
detected using a mammography image dataset. In [103,104] a hybrid model (i.e., CNN + SVM) was developed to detect mass from mammographic scans. CNN was trained using mammogram blemishes and the fully connected layer was used to extract high-level features then these features were used...
Breast cancer is one of the most common cancers in women and the second foremost cause of cancer death in women after lung cancer. Recent technological advances in breast cancer treatment offer hope to millions of women in the world. Segmentation of the breast’s Dynamic Contrast-Enhanced Magneti...
PANDA was also supervised by pixel-wise annotations, including both the pancreas and the lesion, transferred by image registration from annotations on paired contrast-enhanced CT scans in which tumors were more visible. Dataset and annotation details are given in the Methods section. PANDA consists ...
enhanced image such that additional levels of magnitudes are substantially more cognizable to a human eye compared to the 2-dimensional image without the magnitude enhancement analysis; c) displaying a selected portion of the enhanced medical image on a display comprising a display system wherein the...
