[ 1 ] - Comparing diagnostic performance of 131I-metaiodobenzylguanidine (131I-MIBG) and 99mTc-hydrazinonicotinyl-Tyr3-Octreotide (99mTc-HYNIC-TOC) in diagnosis and localization of pheochromocytoma and neuroblastoma
Introduction: The present study was aimed to assess the diagnostic performance of the two imaging methods of 131I-metaiodobenzylguanidine (131I-MIBG) and 99mTc-hydrazinonicotinyl-Tyr3-Octreotide (99mTc-HYNIC-TOC) in diagnosis and localization of pheochromocytoma and neuroblastoma. Methods: This study ...
[ 2 ] - Evaluation of a new 99mTc-Bombesin analog in differentiation of malignant from benign breast tumors
Introduction: The gastrin releasing peptide (GRP) receptor is over expressed in a variety of common human tumors. Radiolabeled bombesin analogues have exhibited high binding affinity for these receptors. The aim of this study was to assess the value of a new 99mTc-bombesin analog in the differentiation of malignant from benign breast tumors. Methods: 99mTc-bombesin scans ...
[ 3 ] - Changes in salivary gland function following radioiodine therapy of thyroid diseases: A comparison of high-dose therapy for thyroid cancer and low-dose therapy for benign thyroid disease
Introduction: High-dose radioactive iodine therapy in differentiated thyroid cancer (DTC) may adversely affect the salivary gland function. This study is aimed to evaluate the effect of radioactive iodine (RAI) with dose of 100 mCi in DTC patients compared to lower doses of less than 30 mCi in hyperthyroid cases. Methods: Fifty four patients (13 men and 41 women) age: 42.3±14.3 (21-71) years w...
[ 4 ] - The myocardial perfusion scintigraphy in asymptomatic diabetic patients
Introduction: Asymptomatic diabetic patients are at increased risk of cardiovascular complications. Myocardial perfusion scan may be effective in risk evaluation in this population. Methods: 106 asymptomatic diabetic patients (age: min: 37, max: 82, mean: 57.73±8.88), including 56 females (52.8%) and 50 males (47.2%) were enrolled in the study. Myocardial perfusion scintigraphy was performed b...
[ 5 ] - Effectiveness and complications of 188Re-HEDP in palliative treatment of diffuse skeletal metastases
Introduction: Bone metastases are the most common cause of cancer-related pain in various primary malignant tumors, most often, breast and prostate. 188Re-hydroxyethylidene diphosphonate (188Re-HEDP) is a new and less expensive bone seeking radiopharmaceutical with favorable physical characteristics of the radionuclide such as short half life of 16.9h, maximal β energy of ...
[ 6 ] - Comparison of transient ischemic dilation ratios in SPECT and SPECT-CT myocardial perfusion imaging in the low pre-test probability group
Introduction: The main purpose of this study was to compare transient ischemic dilation (TID) ratios in SPECT-low dose CT and SPECT Myocardial Perfusion Imaging (MPI) by application of different quantitative programs and quantify the possible shift in the upper normal limits of TID ratio in the SPECT-CT MPI. Methods: 149 Patients with low pre-test probability for coronary artery disease (CAD),...
[ 7 ] - Accuracy of modification of diet for renal disease and Cockcroft-Gault equations as compared to the radioisotope double sample method: A study in patients with acute renal failure
Introduction: We intended to assess the accuracy of re-expressed Modification of Diet for Renal Disease (MDRD) and Cockcroft-Gault (CG) equations to estimate glomerular filtration rate (GFR) in chronic kidney disease in two different etiologies of acute renal failure (ARF): acute tubular necrosis (ATN) and acute glomerulonephritis (AGN). Methods: Patients admitted for ARF or the patients compl...
[ 8 ] - Adrenal lesions: Common findings and pitfalls on 18F-FDG PET/CT
Adrenal lesions are commonly observed during 18F-FDG PET/CT studies. Although, most of these lesions are considered benign, an important consideration in oncologic patients is metastasis. Benign lesions, such as adenomas usually present with low 18F-FDG uptake, although overlap with malignant lesions exist and clear SUV cut-off for distinguishing adrenal adenomas has not b...
