Apparent diffusion coefficient (ADC) measures the magnitude of diffusion (of water molecules) within cerebral tissue. A low value for ADC indicates that the cortical white matter tracts are organized (good), while a high value for ADC indicates that these tracts are disorganized (bad). When evaluating an acute ischemic stroke, ADC image sequences play a crucial role. Ischemic brain parenchyma tends to have a low ADC value. This is in turn correlated with a high diffusion weighted imaging (DWI) value to confirm that the ischemia is not secondary to an MRI artifact known as T2 shine through. The latter would demonstrate a high signal on DWI imaging, but would continue to demonstrate high intensity on ADC sequences.
enhanced/exponential apparent diffusion in a voxel .not affected by T2 shine through.contrast same as diffusion weighted images.diffusion is dark.
It is the same. ADC=MD.
Do you mean "equations involving exponential functions"? Yes,
A number is in exponential form when it is written with a base and an exponent.
a coefficient is the number before the variable.example- 4y the 4 before the y is the coefficient.
The abbreviation ion stands for several things. One of the things it stands for is Inferior Esophageal Nerve. Another item that ion stands for is Ionic Self-Diffusion Coefficient D.
A coefficient is any number in front of a variable .

Of course it is! If the mean of a set of data is negative, then the coefficient of variation will be negative.

The correlation coefficient is symmetrical with respect to X and Y i.e.The correlation coefficient is the geometric mean of the two regression coefficients. or .The correlation coefficient lies between -1 and 1. i.e. .
