Abstract:
Gadolinium is a contrast agent that is used in MRI. There is new evidence that gadolinium accumulates in a patient's body and the effects of this accumulation is unknown. This has resulted in different advice being given by European Medicine Agency and U.S. Food and Drug Administration. The European Medicine Agency recommended stopping the use of linear Gadolinium agents (requiring more proof of safety) while the Food and Drug Administration continues to permit its use (requiring more proof of harm). Gadolinium should be used if deemed clinically necessary. Children and parents should be informed of the benefits and potential harm of using gadolinium-based contrast. It is up for debate whether those imaged before with gadolinium will benefit from being informed of new evidence.

Phase Contrast and Differential Interference Contrast Microscopy
In-phase-contrast microscopes, interference between light directly passing through a cell and light refracted by cellular components is used to create high-contrast, high-resolution images without staining. It is the oldest and simplest type of microscope that creates an image by altering the wavelengths of light rays passing through the specimen. Altered wavelength paths are created using an annular stop in the condenser. The annular stop produces a hollow cone of...
