Background: Bone lesion in multiple myeloma (MM) is most commonly presented as a lytic lesion in this disease. Determination of extent of bone lesions in MM is necessary to follow-up the patients. Whole body bone scan with 99m, Tc-methylene diphosphonate (MDP) has a lower sensitivity than other modalities. Methods: From the patients with MM admitted to Ayatollah Rouhani Hospital of Babol-Iran ...

Pheochromocytomas are rare tumours, 22% of which are extra-adrenal and are known as paragangliomas. We report a case of a young male with non-functioning paraganglioma of the liver; a very uncommon primary site. A CT scan with contrast showed a huge, highly vascular mass lesion in the right lobe of the liver and a core biopsy confirmed it to be a paraganglioma. Whole body study with iodine-131-...

conclusions: this study provides detailed information and case samples of radiodine contamination artifacts and non-physiological, non-metastatic extra-thyroidal i-131 accumulation in whole-body i-131 imaging. introduction: radioactive iodine has been used for more than 50 years for the treatment of thyroid diseases. differentiated thyroid cancers have the ability to trap iodine. therefore, rad...

Post-treatment or diagnostic whole-body radioiodine scintigraphy is widely used to assess the residual, recurrence, or metastases of differentiated thyroid carcinoma because of the high sensitivity and accuracy that this assessment provides. While bearing in mind all the diagnostic potential of this test, we have to consider its’ potential pitfalls, as well. Herein, we present 4 patients with d...

A 73-year-old man with history of prostatic adenocarcinoma radical prostatectomy underwent 99mTc-MDP whole-body bone scan and subsequent 68Ga-labeled prostate-specific membrane antigen (PSMA) ligand PET/CT for restaging due to a gradual rise of prostate-specific antigen levels. Whole-body bone scan showed two focal zones of slightly increased uptake in the right fronto-par...

OBJECTIVE There is no investigation that emphasizes the pathology of DTC (differentiated thyroid cancer) patients with positive Tg and negative iodine scan. The present study was performed to assess the pathology of these patients. MATERIALS AND METHODS In this retrospective study, the records of 500 patients with differentiated thyroid cancer between June 2005 and November 2011 were assessed...

This study investigated the oxidation of ascorbic acid (Vitamin C) using a platinum nanoparticle electrode coated with an iodine monolayer, called a modified electrode. The electrode were grown using the cyclic voltammetry technique and the electrochemical measurements were taken using the cyclic voltammetry and chronoamperometric technique. In the case of platinum nanoparticle electrode modifi...

This is a case of follicular thyroid carcinoma with extensive lung, bone and brain metastases. Multi-modality treatments including total thyroidectomy, modified radical neck dissection, cranial radiotherapy and Iodine-131 (RAI) therapy were instituted. Post RAI therapy planar whole body scan showed RAI avid metastases in the skull, cervical spine, bilateral lungs and abdomen. With the use of SP...
