Internal Jugular Vein Geometry Under Multiple Inclination Angles with 3D Low-Field MRI in Healthy Volunteers.

ABSTRACT:

Background

Cerebral venous pathways are subjected to geometrical and patency changes due to body position. The internal jugular veins (IJVs) are the main venous drainage pathway in supine position. Their patency and geometry should be evaluated under different body inclination angles over a three-dimensional (3D) volume in the healthy situation to better understand pathological cases.

Purpose

To investigate whether positional changes in the body can affect the geometrical properties and patency of the venous system.

Study type

Prospective.

Population

15 healthy volunteers, of which seven males and median age 22 years in a range of 19-59.

Field strength/sequence

A 0.25-T tiltable MRI system was used to scan volunteers in 90° (sitting position), 69°, 45°,
