Since the discovery of X-rays, they have been utilized ubiquitously for medical diagnostic imaging and therapy. Yet despite nearly unlimited ability to measure the transmission of the beam through tissue, there is not currently a way quantify the radiation dose deposited directly in tissue. Technique...
Toxicology studies in rodents and a limited number of epidemiologic studies in populations of girls exposed to chemicals or radiation suggest that adolescence and puberty are in fact critical “windows of susceptibility” to breast cancer [3, 6, 7]. Recent secular changes in the timing and tempo...
Volumetric and positional information from the metadata of the images was used to find the corresponding voxel coordinates of the VOI in the LTF and DWI volumes. Voxels partially outside the VOI were excluded. Perfusion data were analysed as follows; the mean intensity values within each selected...
activation of ATF4 can increase intracellular levels ofreduced glutathioneand clearance ofreactive oxygen speciesafter radiation, leading to radiation resistant [13]. In addition, HER2 can facilitate the proliferation and migration of breast cancer cells. It upregulates the expression of ATF4-ZEB1 [14]...
3D-SI has a number of positive features: image acquisition is fast, there is no contact by the machinery or operator with the patient's body and there is no radiation or chemical exposure risk. The procedure does not require the patient to move into awkward positions or remain still for ...

Being vocal, including expressing any concerns or history you may have, and telling the provider about any physical limitations they should be aware of (such as issues with your shoulders, for example) so they can work with you to get the best images possible. ...
A different approach would have to be chosen to examine the whole lesion (for example, to assess only qualitative parameters of images and to move the probe slightly while recording a video-loop). Also, there is the possibility of three-dimensional perfusion imaging, which has already been ...
lack of ionizing radiation, and the ability to evaluate images in real time4. In particular, US is especially effective at distinguishing solid breast masses from fluid-filled cystic lesions. In addition, breast US is able to detect cancers obscured on mammography, making it particularly useful in...
Despite being the hallmark of cancer that is responsible for the highest number of deaths, very little is known about the biology of metastasis. Metastatic disease typically manifests after a protracted period of undetectable disease following surgery or
