“…[11][12][13] A possible bias in the agreement evaluation method may occur if the radiologists have different experience levels, as has been observed in previous studies. 14,15 In this study, therefore, radiologists with similar experience in head and neck radiology -trained at the same image diagnosis unit -were sought.…”

“…Many papers [4][5][6]12,[16][17][18] have described CT as the best method for image-based staging of cervical lymph nodes. These studies compared image findings with pathology lab findings, obtaining good sensitivity and specificity values in staging cervical lymph nodes, and consequently, their relation with the carotid artery.…”

“…On the other hand, a published paper on carotid artery involvement over 270 degrees assessed by MRI indicated that wall invasion was present in 83% of cases. 12 Based on patient files, only the negative predictive value could be calculated, as only 27 patients were operated. In these resected cases, the negative predictive value was 100%; the pathology reports were present in all of their files.…”

“…Primary lesions were in the mouth (12), nasopharynx (2), oropharynx (30), hypopharynx (22), larynx (23) and hidden primaries (10). All of the patients presented epidermoid carcinoma metastatic lymphadenomegaly, demonstrated by histopathology.…”

“…These had been extrapolated initially from CT assessments of aortic involvement in esophageal carcinoma cases, 11 and used later in the MRI assessment of carotid involvement. 12 One of the CT signs of lymph node involvement was enlargement of lymph nodes (diameter over 1.5 cm) in the axial plane only (Figure 1). A rounded morphology was also suspect, as the usual lymph node shape is oval.…”

Carot id involvement by metastatic lymph nodes changes the approach in head and neck tumors. Aim: To evaluate interobserver agreement by CT scan analysis regarding the involvement of the carotid artery by metastatic lymph nodes from squamous cell carcinoma of the upper aerodigestive tract and its relation to resection criteria. Materials and Methods: retrospective study of 99 CT images of patients with SCC were evaluated. Eighty-six were males and 13 females, with ages ranging from 32 to 76 years. Four radiologists, without any previous knowledge of the clinical stage, analyzed imaging results. No patients had received previous treatment and histological diagnoses were obtained through biopsy. The carotid artery invasion was classified as simple (0 to 50% and from to 100%), and complex (0 to 25%; 26 to 50%; 51 to 75% and 76 to 100%). The level of interobserver agreement was obtained through Kappa Index (p≤ 0, 05) and the concordance power varied from despicable to excellent. Results: The Kappa Index were moderate (0, 53%) for simple classification and minimum (0, 36%) for complex classification. Conclusions: The computed tomography showed low effectiveness in the evaluation of lymph node metastasis resection concerning carotid artery invasion.

The purpose of this study was to clarify temporal changes of carotid wall enhancement using dynamic magnetic resonance (MR) and to correlate its findings with pathological conditions. Cervical carotid arteries of 84 consecutive patients were studied with a 1.5 T MR imager using phased array coils. Axial spoiled gradient‐echo (SPGR) images (30–58 second scan time) with fat saturation were repeated 4–8 times after the injection of contrast material. We evaluated the presence and thickness of hypointense inner rims and hyperintense outer rims of the carotid wall, temporal changes of outer rim enhancement, and their changes in relation to pathological conditions. Hypointense inner rims and enhanced outer rims were clearly visualized in 87% (73/84) of our subjects. Enhancement of the outer rim was minimal in early phases and gradually increased. Patient age had a significant correlation with outer rim thickness. In the portions with large atheromatous plaques, inner rims were disrupted or thickened. A marked thickening of the outer rim was observed in one patient with arteritis. The outer rims adjacent to malignant tumors were often obscured. Our study suggests that dynamic MR images of the cervical carotid artery can uniquely demonstrate angiogenesis of the wall itself. The outer rim of the artery shows relatively rapid enhancement, and its thickness correlates with age.J. Magn. Reson. Imaging 1999; 9:420–427. © 1999 Wiley‐Liss, Inc.

Carotid artery invasion by head and neck masses: prediction with MR imaging.

Abstract: Tumor that encompasses more than 270 degrees of the carotid artery probably cannot be removed from the artery. Tumor that involves 270 degrees or less of the artery can be removed.
