Abstract
- BACKGROUND AND OBJECTIVES
The aim of this study was to compare the effectivenss of 99mTc-MIBI SPECT and CT in evaluating cervical lymph node (LN) metastasis of head and neck cancer. MATERIALS AND METHOD: Histopathologic results of 138 cervical lymph node levels in 26 neck dissected patients were compared with preoperative CT and 99mTc-MIBI SPECT findings about cervical lymph node metastasis. RESULTS: Sensitivity, specificity and predictability of CT and 99mTc-MIBI SPECT were 63.2, 91.6, 87.7% and 52.6, 84.9, 80.4%, respectively. When analyzing CT and 99mTc-MIBI SPECT together, sensitivity and specificity was 78.9, 99.2%, respectively. CONCLUSION: The combined use of 99mTc-MIBI SPECT and CT could increase the accuracy, compared with the single use of either 99mTc-MIBI SPECT or CT, to detect cervical LN metastases.
