MRI Acquisition recommended
MRI protocol completed in less than 5 minutes, non-invasive, with no radiation, and without the use of contrast agents.
Steady-State Free Procession Cine 2D+t Acquisitions
ArtFun+ uses Cine Steady-State Free Procession (SSFP) sequences to perform anatomical measurements for its biomarkers. Specifically, SSFP sequences enable the precise measurement of strain, diameters, and distensibility.
Phase-Contrast Cine 2D+t Acquisitions
ArtFun+ uses Phase Contrast (PC) sequences to perform flow measurements for its biomarkers. Specifically, PC sequences enable the measurement of the net flow and the transit time, which are relevant for the calculation of Pulse Wave Velocity and regurgitation biomarkers.
Thoracic 3D Steady-State Free Procession acquisitions
ArtFun+ uses Thoracic 3D Steady-State Free Procession (SSFP) sequences to perform anatomical measurements for its biomarkers. Specifically, Thoracic 3D SSFP enable the precise measurement of arterial length . which is relevant for the calculation of Pulse Wave Velocity biomarkers.
Systolic and diastolic Pressures measurments
ArtFun+ uses Systolic and diastolic Pressures to measure the pulse pressure which is relevant for the calculation of distensibility biomarkers
Measure blood pressure ideally at the beginning, during and at the end of the MRI scan and if possible, during the cine sequence.
Blood pressure measurement can be done:
Measure central pressure:
