MRI Nasopharynx Technique Axial T1W and T2SPIR Axial and coronal T1W post contrast Report A small focal area of mucosal thickening (depth approximately 8 mm) is present in the central portion of the superior roof of the nasopharynx which is only present on one slice and lies immediately below the skull base. In addition at this site there appears to be a defect just the right of the midline and it is uncertain whether this could be the site of a biopsy, please correlate clinically. The parapharyngeal regions are normal. Several small unremarkable upper cervical lymph nodes are noted.
