MRA Neck Without IV Contrast There is no relevant literature to support the routine use of MRA of the head without IV contrast in the follow-up imaging or the evaluation of known or suspected recurrence of treated cancer of a major salivary gland. MRI Head With IV Contrast There is no relevant literature to support the routine use of MRI of the head with IV contrast in the follow-up imaging or the evaluation of known or suspected recurrence of treated cancer of a major salivary gland. MRI Head Without and With IV Contrast There is no relevant literature to support the routine use of MRI of the head with and without IV contrast in the follow-up imaging or the evaluation of known or suspected recurrence of treated cancer of a major salivary gland. MRI Head Without IV Contrast There is no relevant literature to support the routine use of MRI of the head without IV contrast in the follow-up imaging or the evaluation of known or suspected recurrence of treated cancer of a major salivary gland. MRI Orbits, Face, and Neck With IV Contrast There is no relevant literature to support the routine use of MRI orbits, face, and neck with IV contrast in the follow- up imaging or the evaluation of known or suspected recurrence of treated cancer of a major salivary gland. MRI Orbits, Face, and Neck Without and With IV Contrast MRI orbits, face, and neck without and with IV contrast has superior soft tissue contrast resolution, which facilitates assessment of local recurrence and can be helpful in distinguishing from treatment-related changes and evaluating local tumor response. Evaluation of the treated neck is very often complicated by significant treatment-related changes that can be difficult to differentiate from persistent disease after therapy or recurrence. Because of the superior soft tissue contrast resolution of MRI, it is considered the modality of choice over CECT for imaging of suspected locoregional tumor recurrence.
