Sag T2 TSE small FOV (20 cm) slice thickness 3 mm
Oblique Ax T2 TSE small FOV (22 cm) slice thickness 3 mm - perpendicular to device (plan on sags)
Oblique Cor T2 TSE small FOV (22 cm) slice thickness 3 mm - parallel to device (plan on sags)
Oblique Ax T1 FS VIBE pre small FOV (22 cm) slice thickness 3 mm
Oblique Ax T1 FS VIBE post small FOV (22 cm) slice thickness 3 mm
Oblique Cor T1 FS VIBE post small FOV (22 cm) slice thickness 3 mm
Sag T1 FS VIBE post small FOV (22 cm) slice thickness 3 mm
NOTES:
- The interpreting radiologist should trace the outline of the visualized neoplasm on contiguous Oblique Ax T2 images. Save these ROIs, they will populate the bookmark series in PACS. The Radiation Oncology Dept uses these images to determine dose/plan therapy.
- The interpreting radiologist should comment on positioning of the ring & tandem device.
