abstract

discrepancy between pre & post treatment wbss (low dose & high dose, respectively) is reported. the aim of this study was determination the post-treatment wbs role in the diagnosis of lesions not identified by the pretreatment one. in this study 94 patients (pts) with dtc were evaluated. the results of pre & post treatment wbss were compared. overall, 25.6% of pts revealed more positive lisions in comparison with their pretreatment wbs. the increase in positive results in pts35yr was 25%. in males and females, the increased values were 33.3% & 23.58% respectively. in all types dtc post-treatment wbs revealed more involvement. in cases limited to thyroid, with capsular invasion and with lymph node involvement the increased values were: 20.5%, 28.5% & 35.7%, respectively. in cases with tsh30 mu/l, 22.2% more positive lesions were observed. pts with htg10 ng/ml, post-treatment wbs revealed more lesions in 28% & 21.8%, respectively. conclusion: post-treatment wbs improves rate of detection of thyroid cancer lesions. in our study this was especially true in cases with tsh

Comparison and evaluation of value of thymoglobulin level in serum and I-131 whole body scan (I-131 WBS) in patients with differentiated thyroid carcinoma [Persian]

  This study was done in research institute of nuclear medicine from 1988-1992 for evaluation of the value of serum thyroglobulin level in comparison with 1-131 whole body scan (1-131 WBS) in patients with differentiated thyroid carcinoma. 204 patients who had total or near total thyroidectomy treated with 1-131 were evaluated in this study. Out of 204 patients 136 di...

Extremity Radioactive Iodine Uptake on Post-therapeutic Whole Body Scan in Patients with Differentiated Thyroid Cancer

Objective(s): We investigated a frequency of lower extremity uptake on the radioactive iodine (RAI) whole body scan (WBS) after RAI treatment in patients with differentiated thyroid cancer, in order to retrospectively examine whether or not the frequency was pathological. Methods: This retrospective study included 170 patients with thyroid cancer, undergoing RAI treatment. Overall, 99r (58%) an...

Post-Therapeutic I-131 Whole Body Scan in Patients with Differentiated Thyroid Cancer

Therapy with radioiodine (I-131) has been used for patients with well-differentiated thyroid cancer such as papillary and follicular thyroid carcinoma to ablate normal thyroid tissue or to treat metastatic lesions. The improvement of survival rates and decrease of recurrence rates after I-131 therapy has been documented by retrospective studies (Mazzaferri & Jhiang, 1994; Samaan et al., 1992). ...
