background: suppressive therapy with levothyroxine for reducing the size of thyroid nodules has not been really accepted. the purpose of this study was to assess the effect of levothyroxine on the size of benign thyroid nodules. methods: forty patients with confirmed benign nodule were randomly divided into two groups. group i received 50?g/day levothyroxin for six months but group ii did not t...
conclusion the fdg pet/ct showed a high sensitivity and a high negative predictive value for identifying malignancies in thyroid nodules with indeterminate fnab results. therefore, the fdg pet/ct may be a helpful tool in the clinical management of these nodules. when an fdg positive lesion is detected, further examination is recommended. background thyroid nodules with indeterminate fine-needle...
Background: Lung diseases and lung cancer are among the most dangerous diseases with high mortality in both men and women. Lung nodules are abnormal pulmonary masses and are among major lung symptoms. A Computer Aided Diagnosis (CAD) system may play an important role in accurate and early detection of lung nodules. This article presents a new CAD system for lung nodule detection from chest comp...
Aim: Thyroid scan with sestamibi is used for evaluation of thyroid nodules with the aim of increasing specificity before surgery. In this study we evaluated the role of Sestamibi thyroid scan in candidates for thyroid surgery. Methods and patients: During two years, 37 patients were studied with solitary thyroid nodules, referred for thyroid surgery due to malignant or suspicious FNAB res...
Background: Fine Needle Aspiration (FNA) of thyroid gland has greater sensitivity as compared to other diagnostic modalities for thyroid nodules. The present study was conducted to compare the sonographic findings of cold thyroid nodules with cytologic changes. Materials and methods: For 219 patients, sonography of thyroid nodules was performed by 7.5MHz probes and the following changes were r...
Background: In this study, we investigated the diagnostic power of ultrasound in the diagnosis of malignancy in thyroid nodules in Iranian patients. For this purpose, we examined the relationship between ultrasound findings and pathology findings. Methods: The present study is a retrospective study. The patients with a diagnosis of thyroid nodules who underwent ultrasound and FNA, were include...
Background: Local ablative treatments play an important role for patients who cannot be treated surgically. Radiofrequency ablation is a well-established alternative to surgical treatment of thyroid nodules, however it also has disadvantages. Microwave ablation (MWA) is a new minimally invasive treatment promising several improvements. The aim of this retrospective study was to evaluate the eff...

The prevalence of nodular thyroid disease increases with aging, especially during sixth decade of the life, 5-10% of the general population have one or more palpable thyroid nodules. Nodular goiter is more common in persons living in areas with iodine deficiency. Cold thyroid nodules have been estimated 2.5 times more frequent in iodine areas in comparison with the iodine sufficient areas. ...
