Outcome Measures

Primary Outcomes (1)

  • The prognostic value of post thyroidectomy 99mTCpertechnetate thyroid scan in patient with differentiated thyroid cancer

    The prognostic value of post thyroidectomy 99mTCpertechnetate thyroid scan in patient with differentiated thyroid cancer

    baseline

Interventions

Thyroid scintigraphy was performed just before RIT. 20 min after intravenous injection 99mTc-pertechnetate, anterior images of the neck were acquired using a scintillation camera equipped with low-energy high resolution collimator. Energy discrimination was provided with a 20% window that was centered on the 140 keV peak of 99mTc .
