Preoperative ultrasonography for tumor thickness evaluation in guiding management in patients with early oral tongue squamous cell carcinoma.

Objectives: (1) To assess the statistical correlation between the tumor thickness (TT) by ultrasonography (USG) and microscopic measurement in cases of early oral tongue squamous cell carcinoma (OTSCC). (2) To assess the predictive capacity of TT by ultrasound in detecting nodal metastasis.

Materials And Methods: Prospective analysis was performed in 24 patients for a period of 2 years from 2012 to 2013.

Role of dual time fluorodeoxyglucose (FDG) positron emission tomography-computed tomography in identifying co-existing inflammatory and malignant disease: Who holds it (FDG) longer?

18-fluorodeoxyglucose positron emission tomography-computed tomography (PET-CT) is an integral part of imaging in the follow-up of head and neck malignancies. Very often distinguishing inflammatory/infective from malignant recurrence cannot be made confidently with standard uptake value (SUV) alone, as inflammatory lesions have shown to have a very high SUV, and in some cases both can co-exist. In such doubtful cases, dual time PET-CT (3-5 h delayed) is of paramount importance in confidently differentiating inflammatory/infective from a malignant cause.
