Report

MR PWV aortic phantom study - comparison with catheterization.

General Info

Phantom is a tube with aortic shape, approximate length 50cm, diameter 2.5cm, filled with water.

Pumping rate 52 beats/minute.

MR venc 150.

Images

Phase Contrast (PC) image with calculated centerline and measuring positions equally spaced at 50mm apart (except for the last centerline section).

Charts

Catheter velocity curves for each sampling position (index numbers of curves and positions match).

MR velocity curves for each sampling position (index numbers of curves and positions match).

Tables

Catheter table of lengths, time shifts and PWV results between each of the positions given by their index numbers (shown in columns). Rising slope foot of the curve marker method was used to determine the time shifts.
