Soft Tissue Neck 1.5T

GE Healthcare – MR Gadopiclenol (VUEWAY®) Protocols

Instructions: • If contrast is used, lesions and cancer staging slices may vary based on indication
• Reformat pre and post Sagittal T1 CUBE in Axial and Coronal planes. If CUBE is not available run Axial and Coronal T1 weighted sequences with and without contrast (+/-Fat Sat or Flex)
• Coronal coverage = top of orbits thru manubrium
• Axial coverage = tailored to area of interest (nasopharynx/oropharynx/parotids) cover lesions or area of interest
Position: Supine, head first
Coil: Head/Neck
Landmark: Region of interest

Contrast Agent	Dose	Injection Rate
Gadopiclenol (VUEWAY)	0.05 mmol/kg up to a calculated volume of 10 mL	Hand Bolus usually
Saline Flush	10-20 mL	—
Comments	• Report agent administered and dose • Consider using ARDL for CUBE or Flex sequences if available
