Brief Summary:
The main purpose of the study is to establish a relationship between the administered activity of the radioiodine and absorbed dose in the tumor sites.

Condition or disease Intervention/treatment Phase
Thyroid Carcinoma Metastatic Sites Lung Bone Nodal Other: SPECT scan Not Applicable

Detailed Description:
Study Design - the assessment of patients with multiple tumour sites with metastatic thyroid cancer to correlate the administered activity to absorbed dose. Patients will receive the standard therapy dose of 5.5 GBq as per the hospital policy and there will be no change for the protocol purpose.

Drug Information available for: Thyroid

Intervention Details:
  • Other: SPECT scan
    SPECT scan measures the amount of radio activity that is remaining in patients' body after the consumption of radio iodine for therapeutic purpose

Primary Outcome Measures :
  1. The primary outcome measure is to correlate the predicted dose from the tracer study with the actual absorbed dose measure on the therapeutic scan

Secondary Outcome Measures :
  1. The secondary outcomes will be to assess the response at 6 months post therapy in each patient
