CT
In general, CT can provide better assessment of cortical bone such as
cortical erosion or sclerosis as well as identification of intratumoral
mineralization or calcified matrix which may prove helpful in
differential considerations28. Spatiality of bony
involvement of the tumor is best demonstrated by CT including expected
healing changes post therapy.27,28,36,37.
CT of the head to include the entire skull base should be acquired with
multidetector CT using thin collimation (0.5 – 0.625 mm). Images should
be reconstructed in axial, coronal and sagittal orthogonal planes in
soft tissue and bone algorithms32. Contrast is not
typically necessary when MRI is available. CTA and CTV (or MRA/MRV) are
adjunct radiological exams that can be used to assess vascular anatomy23.
