Tools Descriptions Methods in basic measurement
Types Tools Descriptions Methods or formulae
Calculation Stenosis D Stenosis Diameter Stenosis D (No unit) = (Normal Diam. (cm) -
Resid Diam. (cm)) / Normal Diam. (cm) ×
100%
Stenosis D (No unit) = | (D1-D2) / MAX
(D1, D2)|*100%
Where D1 and D2 refer to the measured
vascular diameter, and MAX (D1, D2)
represents the larger value of the two.
Stenosis A Stenosis Area Stenosis A (No unit) = | (A1-A2) / MAX
(A1, A2) |*100%
Where A1 and A2 refer to the measured
vascular area, and MAX (A1, A2) represents
the larger value of the two.
ICA/CCA / Measures the flow velocity ratio between
ICA and CCA to calculate the stenosis.
Study Stenosis A / Stenosis (No unit) = |(A1-A2)/
MAX(A1,A2)|*100%
Where A1 and A2 refer to the measured
vascular area, and MAX (A1, A2) represents
the larger value of the two.
You may select different method for the two
area measurement.
