UNLABELLED (186)Re-1-hydroxyethylidene-1,1-diphosphonate (HEDP) is an attractive radiopharmaceutical for the treatment of bone pain arising from skeletal metastatic lesions. Currently, (186)Re-HEDP is most commonly used in European countries. The aim of this study was to investigate the palliative efficacy and adverse effects of (186)Re-HEDP in patients(More)
AIM To introduce the combination method of radiochemoembolization for the treatment of selected hepatic metastases. METHODS Twenty patients with biopsy proven hepatic metastases were selected from those who underwent transarterial radiochemoembolization, a novel combination protocol, between January 2009 and July 2010. Patients had different sources of(More)
INTRODUCTION Sentinel lymph node biopsy (SLNB) is a precise procedure for lymphatic staging in early breast cancer. In a valid SLNB procedure, axillary lymph node dissection (ALND) can be omitted in node- negative cases without compromising patient safety. In this study, detection rate, accuracy and false negative rate of SLNB for breast cancer was(More)
Osteosarcoma is the most frequent primary malignancy of bone, and usually metastasizes to the lung and bones, while other sites are rare. In most reported cases, soft tissue metastasis of osteosarcoma is unusual, and only develops in the advanced stages of the disease, especially following multiple recurrences. We present a patient with recently diagnosed(More)
The diagnostic value of somatostatin receptor scintigraphy (SRS) in detecting tumors has been assessed in a number of studies. We present a 30-year-old female with a history of eight months cough and left shoulder pain. Radiologic evaluation showed pulmonary mass and hepatic lesions, which were pathologically diagnosed as neuroendocrine carcinoma.(More)
INTRODUCTION Left ventricle (LV) quantification in nuclear medicine images is a challenging task for myocardial perfusion scintigraphy. A hybrid method for left ventricle myocardial border extraction in SPECT datasets was developed and tested to automate LV ventriculography. METHODS Automatic segmentation of the LV in volumetric SPECT data was implemented(More)
BACKGROUND Because one of the major sites for metastasis of thyroid cancers is the lung, studying the pattern of pulmonary metastasis may provide useful information for the effective treatment of these patients. In this study, by assessing the metastasis pattern, we aimed to identify the factors that may affect prognosis and response to treatment in(More)
Extrarenal uptake of 99mTc-DMSA is a rare finding, which has been described in some unusual conditions as bone metastasis, aortic aneurysm and hemangioma. The purpose of this report is to present two cases of abnormal 99mTc-DMSA uptake in the lungs, which remained unexplained even after radiologic assessment.
PURPOSE Use of radiopharmaceuticals for diagnostic nuclear medicine procedures is one of the main sources of radiation exposure. We performed this study with respect to the rapid growth in nuclear medicine in Iran and lack of updated statistics. MATERIALS AND METHODS The data were obtained for all active Nuclear Medicine Centers affiliated to Shahid(More)
The diagnostic usefulness of somatostatin receptor scintigraphy in the localization of tumors has been evaluated in several studies. Here, we present the case of a patient with a subserosal myoma diagnosed by (99m)Tc-labeled octreotide acetate scintigraphy. Oval and ring-shaped areas of hyperactivity in the pelvis were confirmed on MR imaging to be the(More)
