Pulse-generated runoff: a new method of determining calf vessel patency

A non-invasive method of determining calf vessel patency before femorodistal bypass has been developed. This pulse-generated runoff (PGR) system generates blood $ow in patent calf arteries by means of a pulsatile cuff even i f the existing Doppler signal is inaudible. PGR was compared with pre-operative arteriography in 95 ischaemic limbs and both were compared with the peripheral resistance measured at operation in 62 limbs. There was a highly signijicant correlation between the PGR and arteriogram scores (rs =0*74, P<O.OOI) but PGR tended to detect more patent vessels than arteriography. The peripheral resistance correlated better with PGR than arteriography (rs = -0.71 and -0.54 respectively, P <0.001). PGR is a simple, non-invasive method of determining calf and foot vessel patency pre-operatively.

## Abstract ## Purpose To evaluate the reproducibility of a new multisite axial pulse wave velocity (PWV) measurement technique that makes use of 2D PCMR data and cross‐correlation analysis. ## Materials and Methods PWV was estimated with MRI in 13 healthy volunteers by a transit‐time technique
