In the last two protocols, automated ADC (apparent diffusion coefficient maps) were available. The ADC values from the normal or diseased brain parenchyma were calculated directly from these automatically generated ADC maps with region of interest (ROI) and/or âpixel lensâ evaluation.
A carat is a unit of measure for diamond weight and is evaluated on a point system. One carat is equivalent to 100 points. A karat is the standard measurement of gold, which is divided into 24 parts. Pure gold is 24 karats, meaning 24 out of 24 parts are gold.
Diamond prices typically increase at a higher rate from one weight / price bracket to the next. For example, price per carat for diamonds in the size bracket 1.00â1.49 carats could be $8,000, while price per carat in the bracket 1.49â1.99 carats can jump to $11,000.In a graph below you can see how fast the price per carat jumps with diamond weight moving from one carat weight bracket to another.ecause of this fact, you may occasionally hear some jewelers referring to a 1-carat diamond a âfour grainer,â which means in the past 1 carat was equal to four grains of rice. The weight of smaller diamonds is often expressed as points, not carats. One carat is equal to 100 points.
