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:
a two- or four-year nursing degree and a specialization in dermatology
Explanation:
A "dermatologist nurse" provides assistance when it comes to skin examinations <em>(including its diagnosis and treatment).</em> Whenever patients undergo dermatological surgeries, <em>the dermatologist nurse assists them before and after the surgery</em> and<u> educates them regarding skin care</u> for fast recovery at home.
It is important for Erik to have a nursing degree of at least <em>2 to 4 years</em>. An <em>Associates in Nursing </em>degree requires only 2 years while a <em>Bachelor of Science in Nursing</em> degree requires 4 years. After this, Erik needs to have an experience in dermatology, which means he needs to specialize in it with at least<em> 2,000 working hours</em>.
I'm pretty sure its True. Cuz if you see someone needing medical help you cant just leave them to die just because you are not qualified. Also you can ask for consent from the person.
Answer:
Its formation is a result of the refraction and the total internal reflection of light in the air. To investigate the formation of a mirage, we firstly need to understand why light is refracted in the air. Regions of air at different temperatures have different refractive indexes, just like many different mediums.
