3D Water Bath Ultrasound: Next Generation in Cancer Imaging
Warm Bath Ultrasound (WBU) is a new technology designed to produce 3D breast images in less than 10 minutes. Its based on placing the breast in a warm water bath surrounded by multiple ultrasound transducers, allowing near instantaneous tomographic imaging of the tissue. Read More »
Blood Test, then MRI = New Diagnostic Path for Breast Cancer
How good are breast cancer blood tests? Digital mammography has an accuracy rate for women under age 50 at 84%; film mammography, 69%. The published results for the BT test reflect 97% accuracy. For women over 50, digital mammography has an accuracy rate at 77%; film, 75%; BT, 86% accuracy. Read More »
The FDA Takes on Radiation Exposure
First, lets define which technologies are most affected. One study stated that CT, interventional fluoroscopy, and nuclear medicine studies make up approximately 26% of the imaging procedures using radiation but contributed 89% of the total yearly exposure to radiation from medical imaging. To be more specific, the New England Journal of Medicine listed CT angiography of the chest and spine, myocardial perfusion (nuclear medicine), and cath lab imaging as delivering the highest effective dose per study. But when considering cumulative effects, mammography is also an area of concern. Read More »
Hidden Value of Contrast Agents
Studies have shown that contrast agents can expand the ability of an imaging device. Furthermore, contrast agents are evolving with high-volume studies, such as ultrasound and digital mammography. According to one study, contrast-enhanced digital mammography detected three out of 21 tumors (2 malignant, 1 benign) not indentified with standard mammography. With the difference in survival rates between stages I (100%) and IIA (92%), they offer a great deal to the study. Read More »
