Technical notes "Tongue MRI Protocol"
- Tongue carcinoma should be accurately staged in order to optimise treatment options and preserve organ function.
- Axial T1-weighted images, fat with high signal intensity can be seen interspersed between the muscles of intermediate signal intensity
- Tumour invasion of the floor of the mouth is particularly well seen on coronal images . Sagittal images provide information on tongue base involvement and the extent of pharyngeal infiltration
