Validation Study of a Magnetic Sensor in Arterial Flow Recording, Compared With the Reference Method (Echodoppler), at Various Peripheral Arterial Sites
The measurement of magnetic fields emitted by cardiac activity has already been studied in magneto-cardiography. To date, however, this technology has never been evaluated in the peripheral circulation.
The magnetic susceptibility of iron in the circulating blood and the ionic currents in the blood stream generate a very weak induced magnetic current, which can be detected by the micro-sensor of the prototype investigators wish to study.
Proving the validity of this prototype would make it a new diagnostic and even prognostic tool, non-invasive, less costly and more accessible than Doppler for screening peripheral arterial disease.
Inclusion: Patients hospitalized in the Heart-Lung Unit of the Montpellier University Hospital, for any reason whatsoever; Patient with lower extremity artery disease (LEAD) (stage 1 to 4 according to Leriche and Fontaine) or not (absence of LEAD); Age ≥ 18 years.
Exclusion: Patient with a metal implant in the vicinity of the device's area of use; Patient requiring additional hygiene precautions; Subject not affiliated to a social security scheme or not benefiting from such a scheme; Pregnant or breast-feeding woman, patient unable to give consent, protected adult, vulnerable persons; Subject deprived of liberty by judicial or administrative decision; Patient refusing to give consent.
