Answer: Spin Echo TOF


⩥ Vortex flow is usually seen after a narrowed area in a vessel (called a
stenosis).
Answer: true

Answer: Transverse sinus


⩥ Plug flow is shown above.
Answer: false

, ⩥ Bright Blood GRE MRA techniques can be very adversely affected by
motion.
Answer: true


⩥ Spin Echo TOF works best when:
I. Blood is flowing perpendicular to the slice.
II. Blood is flowing fast.
III. Thick slices are used.
IV. TE is long.
Answer: I, II, IV only
