Double Bolus Application in TWIST-MR-Angiography of the Cervical Arteries
Figure 4
Comparison of a standard high temporal and low spatial resolution TWIST-MRA (a) and a high spatial resolution TWIST MRA (b) in two different patients. Due to the lower spatial resolution the vessels in (a) appear blurred and vascular anomalies like stenosis or fenestration (e.g., arrow in b) might be missed.
