Presentation on theme: "Slice thickness: 5–6mm Slice gap: 20% of slice thickness (!1–1.2mm or factor 1.2) Matrix: 512 FOV: 220–240mm Saturation slab: parallel to the slices,"— Presentation transcript:

1 Slice thickness: 5–6mm Slice gap: 20% of slice thickness (!1–1.2mm or factor 1.2) Matrix: 512 FOV: 220–240mm Saturation slab: parallel to the slices, inferior to the most caudad slice (50–80 mm)

2 Sequence 2 axial (orientation, slice thickness, and slice gap as sequence 1)
T1-weighted SE: TR = 450–600 TE = 12–25 3-D FFE: TR as short as possible TE = 4–5 (1.5 T), 6.9 (1.0 T), 10–12 (0.5 T) Flip angle 30–70° Proton-density-weighted — TR = 2000–3500 — TE = 15 — Slice thickness: 5–6mm — Slice gap: 20% of slice thickness (!1– 1.2mm or factor 1.2) Sequences 1 and 2 as double echo (T2/proton-density-weighted) axial (orientation, slice thickness, and slice gap as sequence 1) — TR = 3000–4500 — TE = 15/100

3 Sequence 3 Coronal (FLAIR) (Orthogonal to sequence 1)
Thin slice coronal scanning of brain may be required in case of pituitary gland pathology. To perform this, the mid scan line is made parallel to the pituitary stalk and make sure that the whole pituitary gland with associated pathology is scanned. Using MRI Equipment 1.5 T TR = 9000 TE = 120 TI = 2300 Using MRI Equipment 1.0 or 0.5 T TR = 5000 TE =100 TI = 1900 Slice thickness: 6mm Slice gap: 20% of slice thickness (! 1.2mm or factor 1.2) Saturation slab: orthogonal to the slices (axial superior to the neck)

4 Sequence 4 sagittal (T2-weighted)
Slice thickness: 5–6mm Slice gap: 20% of slice thickness (!1.0–1.2mm or factor 1.2) Saturation slab: orthogonal to the slices (axial superior to the neck), or activate flow compensation
