BACKGROUND Differentiated thyroid cancers (DTC) often form metastases in neck lymph nodes, lungs and bones. Other metastases--to the brain, kidneys, skin and liver are rare. Liver metastases of DTC occur in the terminal phase of the disease and predominantly do not accumulate radioiodine. Functional (accumulating radioiodine) metastases are very rare. MATERIAL AND METHODS In an 85 year old pa...

Molecular imaging plays an important role in the evaluation and management of thyroid cancer. The routine use of thyroid scanning in all thyroid nodules is no longer recommended by many authorities. In the initial work-up of a thyroid nodule, radioiodine imaging can be particularly helpful when the thyroid stimulating hormone level is low and an autonomously functioning nodule is suspected. Rad...

Introduction:Differentiated thyroid carcinoma (DTC) follow-up after thyroidectomy and radioiodine-ablation is performed mainly by thyroglobulin (Tg), diagnostic iodine-131 whole body scan (DxWBS) and sonography. Some patients with undetectable Tg have thyroid-bed uptake after ablation in whom decision making regarding the need for retreatment is still controversial. Me...

INTRODUCTION Malignant struma ovarii is a rare ovarian neoplasm composed predominantly of mature thyroid tissue. CASE REPORT A right ovarian tumor was discovered at ultrasound examination in a 20-year-old woman. Complete right ovariectomy was done - histopathological examination revealed papillary thyroid carcinoma arising in struma ovarii (malignant struma ovarii). Patient underwent subseque...

The presented work describes the thyroid pathologies and nuclear-medical diagnostic approach, in order to obtain a differential diagnosis monitoring of various neoplasms; specifically, it importance radiometabolic treatment with iodine 131, after thyroidectomy surgery. Through study conducted patients suffering from disease, undergoing metabolic radiotherapy, is shown that, equal distribution r...

A male patient had undergone total thyroidectomy for thyroid papillary carcinoma. He was administered thyroablation activity of radioiodine. Whole body imaging after diagnostic activity of 131-I demonstrated intense radioiodine uptake in the right side of the upper abdominal region. The serum thyroglobulin level was low. Ultrasonography demonstrated a large irregular anechoic structure in the c...

The objective of this study were to obtain dosimetric data from a patient with thyroid cancer simultaneously undergoing peritoneal dialysis therapy, so as to determine the appropriate amount of 131I activity to be applied therapeutically. Percentages of radioiodine in the blood and the whole-body were evaluated, and radiation absorbed doses were calculated according to OLINDA/EXM software. Whol...

Objective SPECT/CT has numerous advantages over planar and traditional SPECT images. The aim of this study was to evaluate the role of post-radioiodine therapy SPECT/CT of patients with differentiated thyroid cancer (DTC) in early risk classification and in prediction of late prognosis. Patients and methods 323 consecutive patients were investigated after their first radioiodine treatment (11...
