CT Chest Without IV Contrast CT chest without IV contrast can accurately identify pulmonary metastasis and be used to detect thoracic nodal and skeletal metastases to the ribs or vertebrae. Pulmonary metastatic disease is the single most common site of metastatic disease beyond the head and neck in suspected or confirmed metastatic disease at follow-up. CT chest confers 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 by distinguishing the nodes from mediastinal vessels. 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 follow-up imaging or evaluation of known or suspected recurrence of treated 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 follow- up imaging or evaluation of known or suspected recurrence of treated 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 follow-up imaging or evaluation of known or suspected recurrence of treated cancer of a major salivary gland. CT Maxillofacial With IV Contrast There is no relevant literature to support the routine use of CT maxillofacial with IV contrast in follow-up imaging or evaluation of known or suspected recurrence of treated cancer of a major salivary gland. CT of the maxillofacial region may provide sufficient coverage for the anatomic evaluation of the primary tumor site.
