Instructions And Patient Preparation<\/h3>\n
\n
Instructions<\/dt>\n
Optional sequences added to the brain core based on clinical indication.<\/dd>\n
Position<\/dt>\n
Head first supine<\/dd>\n
Coil<\/dt>\n
Head 20 or Head 64<\/dd>\n
Patient Preparation<\/dt>\n
Landmark per department pediatric protocol — pending sign-off.<\/dd>\n
Add-On Sequence Indications and Coverage<\/dt>\n
• Optic Pathway Glioma<\/strong> — COR T2 TSE W\/ FAT SAT: Cover mid globe through floor of 4th ventricle.
• Craniopharyngioma<\/strong> — COR CISS (SELLA): Cover back of globe to mid thalamus.
• Embryonal Tumor<\/strong> — Replace TRAN T2 FLAIR FS with TRAN T2 FLAIR FS 2.5 (only difference between the sequences is slice thickness).
• Scalp or Osseous Calvarial Lesion<\/strong> — COR STIR covering all soft tissue from tip of nose through posterior scalp.
• IAC<\/strong> — TRAN CISS IAC (ISO). MPR images into Coronal and Sagittal planes. This is a very long isotropic sequence. If a radiologist is available to check the images, coverage can be narrowed down. If no radiologist available, coverage is as follows: Superior — Above midbrain; Inferior — Lower border of C2; Anterior — Mid orbit; Posterior — Soft tissue of occipital scalp; Left to Right — Skin to skin.
• High Grade Glioma<\/strong> — TRAN DSC WHOLE BRAIN: see Contrast Agent Parameters above for injection timing.<\/dd>\n<\/dl>\n<\/section>\n

Contrast Agent Parameters<\/h3>\n\n\n\n\n\n\n
Contrast Agent<\/th>\nDose<\/th>\nInjection Rate<\/th>\nDose Timing Method and Scan Delay<\/th>\n<\/tr>\n<\/thead>\n
Gadopiclenol (VUEWAY)<\/td>\n0.05 mmol\/kg<\/td>\nDSC: power injected at 4 mL\/s<\/td>\nDSC perfusion (TRAN DSC WHOLE BRAIN) — injected during the 15th dynamic; acquired for 60 dynamics<\/td>\n<\/tr>\n
Comments<\/td>\n• Among these optional sequences, contrast affects only the DSC perfusion and the TRAN T2 FLAIR FS; the other add-ons may be acquired at any time or as clinically indicated. CISS is typically performed pre-contrast.
• Use minimal dose for patients with a GFR <60 mL\/sec
• Report agent administered and dose<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/section>\n
