Abstract:
The study was conducted at the department of Nuclear Medicine at the
Radiation and Isotope Center of Khartoum RICK during the period from
October 2009 to June 2010 . The aim of the study was to evaluate the
abnormal thyroid by using 99m Tc uptake and Radioimmunoassay for 50
patients, they were selected randomly from the daily clinic to the
department ( 39 female and 11 male ) . The mean age of the paƟent was
41,8± 15,1 which is range from 12 to74 years. The result showed that,
variable disorder like diffuse goiter , multi nodular goiter , diffuse simple
goiter, cold nodule and hot nodule. There is higher incidence of thyroid
abnormality in female than male 4:1, while 50% of paƟent their age
range from 21-40. The shape of thyroid (i.e. regular and irregular) and
homogeneity of radiotracer (i.e. homogeneous and inhomogeneous) has
no effects on the T3, T4, TSH and uptake. But these quanƟƟes were
affected by the age factor in a linear fashion; inversely with the TSH and
uptake, and directly with T3 and T4. As well the thyroid uptake was
linearly associated with the T3 and T4 inversely, while with TSH was
directly.
