All over the years, cancer present in the breast has been monitored and detected by progressing imaging technologies. Breast cancer is said to be one of the dominant causes of death in females. Various advancements have boosted the capability to detect breast cancer in early stages that resulted in raised rates of survival among victims suffering from it as breast tumors being detected in early stages is extremely important. The present initial techniques of screening in women who have breasts that are radiographically dense are neither detailed nor dependable.
A greater number of patients consider the traditional X-ray mammography as it uses doses low in radiation and renders images high in quality; however women with breasts that are radiodense may not be acquiring sufficient results. Various studies suggest that about 15% of breast cancer lacerations are missed out by this technology. Other technologies used for imaging like ultrasound and magnetic resonance imaging have given propitious results along with options such as positron emission tomography,scintimammography, optical imaging and magnetic resonance spectroscopy as these are being considered helpful. However, it is suggested that X-ray mammography renders specific diagnosis over all these options. It also suggested that high sensitivity and specific diagnosis cannot be provided by any imaging technology at the same time.
Principles of Imaging Analysis
The 3 most important principles goals that imaging is based upon are:
- To analyze the abnormalities present in the tissues of the breast.
- To locate the complexities inside the breast to suggest and simplify further treatment.
- To classify the abnormal tissues in order to make decisions of further treatment accordingly.
It is said that a typical technology should be achieving all these three goals in just one use which is not possible in reality. This being the reason doctors focus on accomplishing one goal at a time. The developers are working on breast imaging technologies that are more accurate, reasonable and practical.
Morphological discrepancies are mapped by present imaging techniques like angiogenesis, microcalcifications and tissue masses. Mechanical, chemical, physical, biological and electrical properties are kept in mind for breast imaging technologies as their application is various but the purpose of these technologies are common. Digital Mammography on the other hand provides advantages like magnification, brightness and contrast in order to separate the image as displayed and manipulate it which may help in detecting breast cancer in intricate areas with a single exposure. Real-time imaging, transmission, retrieval and easy of archiving of digital images are also some of the advantages provided by digital mammography.
