Hounsfield Unit (HU) Measurements
This procedure checks consistency in various measurements. The
positioning and dimension of each Region of Interest (ROI) is very
important. Be consistent between each assessment to achieve the
minimum deviation.
28. Zoom the Axial image (upper left). To zoom, start at the lower
right corner of the image and drag the cursor across the image.
For consistency, ensure that the slice selection to be measured is
setup as follows.
a. Right click top-left image and select Set Filter > Normal
b. Click the top of the right-hand scale, and select Show as
MIP .
c. At the bottom of the scale, click and hold the cursor on the
●
symbol. The slice thickness is displayed.
Sliding the cursor up and down changes the value. The minimum
value is 0.2 mm in this case, which is selected on this slice.
