radiopaque bone, surrounded by a lucent region on the ventral mandible, consistent with a sequestrum. Computed tomography (SOMATOM Force; Siemens Medical Solutions USA Inc) images were obtained to evaluate the extent of the sequestrum ( Figure 3 ) . Computed
radiographic interpretation difficult. Other radiographic modalities that may be used include magnified radiography and the use of high-resolution mammography film or dental films. 6 Computed tomography has been found to have a higher diagnostic yield than
, other than identification of rare reactive lymphocytes. The dog was anesthetized and positioned in sternal recumbency, and computed tomography was performed. Transverse, 1.25-mm-thick images of the head and neck were obtained before and after

; VetCAT cone beam computed tomography; Xoran Technologies LLC) of the skull was performed (0.3-mm slice thickness, 120 kVp, 57.6 mAs, and 16 X 16-cm field of view; Figure 3 ). All digital images were evaluated with commercially available software (VetCAT
rather than invasive nature of this neoplasm. Computed tomography is the ideal imaging modality for many lesions involving the skull, particularly for lesions involving the palate. Computed tomography eliminates superimposition and allows 3-D
(arrows; B). Computed tomography was performed for further evaluation. Contiguous, 0.625-mm-thick, transverse images of the skull processed with a bone algorithm (120 kV; 79 to 131 mA; field of view, 157 × 157 mm in a 512 × 512-pixel matrix) were
, the dog had a single episode of epistaxis and had been evaluated at a different referral facility. Computed tomography of the head was performed, revealing a right-sided nasal mass with possible invasion into the cribriform plate. Histopathologic
could not provide. Computed tomography also overcame the superimposition of anatomic structures inherent during use of conventional radiographic techniques for imaging the maxilla, allowing more accurate surgical planning. Although an incisional biopsy
evident. Computed tomography of the skull was performed to evaluate the patient for other possible maxillofacial injuries. Gas opacities were observed within the pulp cavity and within the remaining periodontal space of the right maxillary canine
