For this reason, CT of the chest may be considered in cases of increased risk of metastatic disease, in particular in patients with high-grade malignant tumors. CT chest confers a superior spatial localization and contrast resolution compared to radiography, allowing for the detection of small pulmonary nodules [15]. The use of IV contrast may improve detection of mediastinal and hilar adenopathy and aid in delineation of the soft tissue extension of skeletal metastatic disease. Noncontrast CT chest may be considered as an alternative and is part of routine clinical practice, although there is paucity of relevant supportive literature evaluating the use of CT chest without IV contrast. CT Head With IV Contrast There is no relevant literature to support the routine use of CT of the head with IV contrast in the initial staging of suspected or diagnosed cancer of a major salivary gland. CT Head Without and With IV Contrast There is no relevant literature to support the routine use of CT of the head without and with IV contrast in the initial staging of suspected or diagnosed cancer of a major salivary gland. CT Head Without IV Contrast There is no relevant literature to support the routine use of CT of the head without IV contrast in the initial staging of suspected or diagnosed cancer of a major salivary gland. Assessment of Head and Neck Cancer CT Maxillofacial With IV Contrast There is no relevant literature to support the routine use of CT maxillofacial with IV contrast in the initial staging of suspected or diagnosed cancer of a major salivary gland. CT of the maxillofacial region may provide sufficient coverage for the anatomic evaluation of the primary tumor site. However, CT maxillofacial will typically not include evaluation of the neck and would therefore be inadequate for the staging of regional lymphadenopathy when performed alone and may best be used in combination with MRI or FDG-PET/CT.
