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.
First of all, diamonds are all priced per carat. So, lets say a 0.50 carat diamond has a price of $1400 per carat. That diamondâs price for the stone would be $1400 * 0.50, or $700. Secondly, diamond prices per carat increase as you jump up to higher weight categories.herefore, diamond prices increase exponentially with weight, since their prices increase both due to the increased weight and due to the higher price per carat for the increased weight category.
