Patients with central venous obstruction or restricted
venous access may benefit from venous imaging, but
contrast agent administration is not possible in this
group. We investigated four free-breathing
(navigator-gated) and four breath-hold subtractive
NCE-MRA sequences, assessing their utility in imaging
the superior vena cava (SVC), innominate veins and
subclavian veins, in 12 healthy volunteers. These
sequences combine DANTE or dual iMSDE flow-suppression
methods with either balanced SSFP or gradient echo
readouts. The navigator-gated methods always gave
diagnostic image quality in the SVC and innominate
veins, which are hardest to visualise using ultrasound,
with DANTE methods performing slightly better than iMSDE.
