method for the continuous measurement with radionuclides of intravascular volume in studies of physiology and physical therapy

摘要

the invention belongs to. the field of biotechnology.it is applicable in studies of physiology and pathophysiology whenever necessary to measure continuously the arterial flow to a limb and changes in intravascular volume in any bed vasespecially through the revelation of an appropriate radionuclide, injected or otherwise introduced into the body.the present method (gamma camera) allows to: - a) measure the activity all the time; (b) to measure simultaneously from several vascular beds; (c) to the previous operationduring exercise test.the invention provides a measure of the patient posizionabili detectors continuously by the activity of radioisotopes from any vascular bed and in any condition of evidence of the patient.at rest and during exercise.the invention enables the measurement of haemodynamic changes due to changes in posture and the muscle exercise in normal subjects and in those conditions, for example with ipotensione orthostatic hypotension and heart failure, and allows the level of arts collection is that arterial venous insufficiency in patients with flebopatia and arterial disease.
