A 50-year-old man with postprandial abdominal pain, weight loss, and generalized body ache was referred to Nuclear medicine department for a whole body bone scan to look for any malignancy. Clinical examination did not reveal any specific positive findings. He underwent aTechnetium-99m Methylene Diphosphonate (99mTc-MDP) bone scan which showed no obvious bone pathology. But there was...

a 54 years old female with history of total thyroidectomy for papillary carcinoma, treated with loomci of iodine-131 and negative whole body scans was referred for follow up study. tl-201 scan revealed an area of radiotracer uptake in the neck region, suggestive of a parathyroid adenoma versus recurrence of thyroid carcinoma. the patient was operated, the parathyroid adenoma was removed. in thi...

BACKGROUND The purpose of using a whole-body scanning after the radioactive I-131 treatment is to screen functional residual or metastatic thyroid tissues. In whole-body scanning of some patients, false positive radioiodine I-131 uptakes may be seen in physiological uptake regions or atypical localizations. CASE REPORT A 54 year-old woman underwent total thyroidectomy for papillary thyroid ca...

PURPOSE In this study, we examined whether additional, delayed regional FDG PET scans could increase the accuracy of the lymph node staging of NSCLC patients. MATERIALS AND METHODS Among 87 patients who underwent open thoracotomy or mediastinoscopic biopsy under the suspicion of NSCLC, 35 (32 NSCLC and 3 infectious diseases) who had visible lymph nodes on both preoperative whole body scan and...

A 54 years old female with history of total thyroidectomy for papillary carcinoma, treated with lOOmCi of iodine-131 and negative whole body scans was referred for follow up study. Tl-201 scan revealed an area of radiotracer uptake in the neck region, suggestive of a parathyroid adenoma versus recurrence of thyroid carcinoma. The patient was operated, the parathyroid adenoma was removed. ...

Measurement of serum thyroglobulin (Tg) concentrations and whole-body radioiodine scan were performed simultaneously during follow-up of 32 patients with differentiated thyroid cancer who had undergone thyroid ablation by operation and radioiodine. Almost all patients in whom serum Tg was undetectable had normal scans. Concentrations exceeding 50 ng/ml were invariably associated with residual o...
