“…It has added value for detection of soft tissue extent, marrow involvement, and perineural spread [3]. The excellent tissue characterization and multiplanar imaging capability of MR imaging results in more accurate diagnosis of neoplastic and benign processes [4,5].However, early investigators credited MR imaging with greater precision in head and neck imaging than was warranted [6]. Conventional MR imaging did not have the last word in histological specificity, early detection of primary malignancy and differentiating neoplastic from inflammatory lymph nodes.…”

Computerized tomography (CT) and magnetic resonance imaging (MRI), positron emission tomography (PET) and the hybrid modality of PET/CT are sensitive and reliable tools for detection and staging of head and neck cancers. This article describes the role of PET/CT in initial staging of head and neck squamous cell carcinoma, the utility of CT/MR perfusion imaging in qualitative analysis of tumor tissue, and the usefulness of diffusion weighted MR and dynamic contrast-enhanced MR imaging in head and neck oncological imaging.

“…The development of the helical multi detector computerized tomography (MDCT) has the advantage of faster CT scans with rapid acquisition of numerous thin (0.5 to 1mm thickness) images in axial, coronal and sagittal planes. Furthermore, excellent soft tissue delineation of tumor extent and reconstructed Shaded Surface display SSD of bony structures is possible and more accurate images than linear CT and conventional spiral CT are obtainable 7 . Tumor volume, lymph node infiltration distant metastases are the most important factors that influence the therapeutic approach and the prognosis of the patient with HNC 5,8 .…”

Introduction/Objectives: To assess the efficacy and correlation of MDCT scans in the clinical staging of patients with HNCs prior to therapeutic intervention. Methodology: Thirty-four HNCs were studied according to the 2005 WHO. Clinical AJCC 6th edition & radiological staging. Results: 14 Squamous Cell Carcinoma (SCC 41.2%) mean age 49.4 + 14.7 years, 13 Nasopharyngeal Carcinoma (NPC 38.2%) mean age 37.1 + 20.5 years, 3 Odontogenic Carcinoma (ODC 8.8% made up of 2 cases ameloblastic carcinoma 5.9% and 1 case of ameloblastic carcinosarcoma 2.9%). Others cases were 3 Adenocarcinoma (8.8%) and 1 Sinonasal Carcinoma NC (2.9%). Mean age insignificant according to gender (p = 0.342). Sensitivity, specificity, positive & negative predictive values and accuracy of clinical and radiological nodal involvements were: (47.4%; 80%; 61.8%; 75%; 54.5%) & (78.9%; 93.3%; 85.3%; 93.8%; 77.8%) respectively. Difference between clinical and radiological stages was statistically significant (X2= 260.8; p=0.01). There was a low but positive correlation between the clinical and radiologic stages (Pearson's correlation r = 0.6). Conclusion: MDCT was significantly more accurate than clinical examination in the TNM of HNCs using AJCC/UICC TNM guidelines. Authors recommend MDCT as first line imaging technique in resource limited settings.

“…[7] Current anatomic imaging methods based on recognition of abnormal masses are inadequate in assessing whether or not viable tumor is present. [8] The metabolic information from FDG18 PET has been reported to be very useful in the assessment [ Figures 1-3] of treatment response. [9] Several studies in lymphoma and esophageal cancer have shown that PET-CT imaging has a higher accuracy compared with CT imaging for the assessment of residual disease and is also predictive of patient outcome.…”
