“…As a rule, between 40 and 60% of all occult metastases are found using either CT or MRI, at the cost of some false positives. Most studies that have compared the accuracy of CT to MRI for the assessment of the neck have found no significant difference between these two modalities [26,36,40,46,47]. An important reason for false-negative interpretations is the fact that in 25% of the tumor-positive neck dissections only (undetectable) micrometastases smaller than 3 mm are present [39].…”

Imaging is playing a major role in the assessment of cervical lymphadenopathy. In infectious disease, the assessment of abscess formation and the relation of the abscess to surrounding vital structures is crucial for its management. In head and neck malignancies, imaging can be helpful for staging. Imaging of the neck for the assessment of nodal metastases can be used to detect occult metastases or to assess operability of palpable metastases. The detection of small occult metastases has limitations, as micrometastases cannot be depicted; however, imaging can fulfill a role in diminishing the risk of occult metastases, and thus influence management. For this purpose a very sensitive technique is necessary. The currently used radiological criteria are not sensitive enough to accomplish enough reduction of the risk of occult metastases; therefore, more sensitive CT and MRI criteria, but especially ultrasound-guided aspiration, should be employed to assess the clinically negative neck.

“…Studies have proposed the use of imaging techniques such as ultrasound (12,13,14,15) , Computed Tomography (16,17,18,19,20) , Magnetic resonance imaging (21,22,23,24) , and radionuclide scintigraphy (25,26,27,28,29) . These investigations have helped in improving the sensitivity and specificity for the detection of Lymph node involvement to a great extent.…”

“…CT (B contrast medium) is generally considered superior to palpation [11,12]. In a collective of 25 patients and 33 performed neck dissections, CT revealed an accuracy of 84.9% in terms of screening the N 0 neck compared with palpation (69.7%) and US alone (72.7%) [13].…”

Squamous cell carcinoma is the most common malignant neoplasm of the larynx. One of the most important influences on prognosis is the presence of metastases to the cervical lymph nodes. Accurate determination of lymph node involvement is therefore a prerequisite for individualized therapy in patients with squamous cell carcinoma of the larynx. Clinical palpation of the neck is not very accurate and the role of imaging techniques such as ultrasound, ultrasound-guided fine needle aspiration cytology, color Doppler ultrasound, computed tomography, magnetic resonance imaging and positron emission tomography is being applied in order to improve upon the results of clinical investigation alone. According to our investigations and review of the literature, the accuracy of computed tomography scanning (84.9%) and magnetic resonance imaging (85%) was superior to palpation (69.7%) and ultrasound (72.7%). Ultrasound-guided fine needle aspiration cytology showed an accuracy of 89% and was in the same range with positron emission tomography (90.5%).
