Intervention type: DIAGNOSTIC_TEST
Group type: EXPERIMENTAL
Intervention: 18 F-FMISO PET/CT
Description: The 18F-FMISO PET/CT Scan Protocol consists first of an IV bolus injection of approximately 5-10 mCi of the radiotracer. At between 150-180 mins post injection, 18F-FMISO images will be acquired.

Intervention: Cisplatin
Description: Concurrent chemotherapy (2 cycles) will be given. At the start of week 1 of radiation, subjects will receive cisplatin 100 mg/m2 intravenously. They may be given for 2 consecutive days (50 mg/m2 each day for a total dose 100 mg/m2 ), typically on days 1 and 2, or as a single dose, typically on day 1.

Intervention: Carboplatin
Description: If cisplatin cannot be given at 100 mg/m2 for either cycle 1 or cycle 2, the investigator may use a regimen with carboplatin and 5-Fluorouracil in its place. Carboplatin will be given at a dose of AUC 1.25 intravenously daily x 4 days starting on day 1 of the cycle (total dose of AUC 5). 5-Fluorouracil will be given at a dose of 600 mg/m2 intravenous infusion over 24 hours daily x 4 days (total dose of 2400 mg/m2 intravenous infusion over 96 hours).~(Cohort B to start carboplatin (AUC 1.5) and paclitaxel 45 mg/m2 at the start of RT)
