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 refers 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 refers to the measured
vascular area, and MAX（D1，D2）
represents the larger value of the two.
