Intracranial Blood Flow Quantification by Accelerated Dual-venc 4D Flow MRI: Comparison With Transcranial Doppler Ultrasound.

ABSTRACT:

Background

Dual-venc 4D flow MRI, recently introduced for the assessment of intracranial hemodynamics, may provide a promising complementary approach to well-established tools such as transcranial Doppler ultrasound (TCD) and overcome some of their disadvantages. However, data comparing intracranial flow measures from dual-venc 4D flow MRI and TCD are lacking.

Purpose

To compare cerebral blood flow velocity measures derived from dual-venc 4D flow MRI and TCD.

Study type

Prospective cohort.

Subjects

A total of 25 healthy participants (56 ± 4 years old, 44% female).

Field strength/sequence

A 3 T/dual-venc 4D flow MRI using a time-resolved three-dimensional phase-contrast sequence with three-dimensional velocity encoding.

Assessment

Peak velocity mea
