Answer:
Breast cancer constitutes about one-quarter of all cancers and is the leading cause of cancer death in women. To reduce breast cancer mortality, mammographic screening programmes have been implemented in many Western countries. However, these programmes remain controversial because of the associated radiation exposure and the need for improvement in terms of diagnostic accuracy. Phase-contrast imaging is a new X-ray-based technology that has been shown to provide enhanced soft-tissue contrast and improved visualization of cancerous structures. Furthermore, there is some indication that these improvements of image quality can be maintained at reduced radiation doses. Thus, X-ray phase-contrast mammography may significantly contribute to advancements in early breast cancer diagnosis. Feasibility studies of X-ray phase-contrast breast CT have provided images that allow resolution of the fine structure of tissue that can otherwise only be obtained by histology. This implies that X-ray phase-contrast imaging may also lead to the development of entirely new (micro-) radiological applications. This review provides a brief overview of the physical characteristics of this new technology and describes recent developments towards clinical implementation of X-ray phase-contrast imaging of the breast.

Answer: False
Explanation:
Aerobic respiration refers to the use of oxygen by the body's cells to convert carbohydrates, amino acids and fats into energy while Anaerobic respiration releases energy by doing the same only it does so without oxygen.
Anaerobic respiration usually happens when the body is engaged in an activity that needs more oxygen than the lungs can supply.
These two energy sources usually work together to supply the body with enough energy however, the amount that each gives depends on the activity being done.
