[ 1 ] - Additive clinical value of bone scintigraphy in patients with malignant tumors with absence of localized bone pain: A report on most common sex-related cancers
Introduction: Almost all malignant tumors have the potential to eventually produce bone metastasis. The aim of the current study was to report the distribution pattern and imaging characteristics of bone metastases detected by conventional whole body bone scintigraphy in patients with different types of malignancies and to assess their relationship with the complain...
[ 2 ] - Breast 99mTc-MDP uptake in a man mimicking metastatic lesion of the ribs
A 65 year-old overweight man with a history of prostate cancer was referred to our nuclear medicine department for bone scanning. Anterior projection images showed two small foci of increased radiotracer uptake corresponding to the anterior arcs of the right and left sixth ribs, which were interpreted as suspicious for metastatic involvement. Eight months later the ...
[ 3 ] - A study of demographic and clinical features of patients referred to the nuclear medicine department of a military hospital for myocardial perfusion scintigraphy
Introduction: It seems that demographic and clinical features of patients referred for myocardial perfusion scintigraphy (MPS) is different among populations and healthcare settings. The purpose of the current study is to evaluate the clinical features and risk factors of patients referred for myocardial perfusion scintigraphy to a military hospital. Methods: As a ...
[ 4 ] - The first experience of stem cell labeling in Iran using 111In- Oxine [Persian]
Introduction: The field of stem cell biology and regenerative medicine is rapidly moving toward translation to clinical practice. Stem cell therapy seems to be a new treatment option for some diseases. So, tracking the distribution of stem cells is crucial to their therapeutic use. Based on this fact we labeled human mesenchymal stem cells (MSCs) with 111...
[ 5 ] - Catheter related artifacts on bone scans: report of two cases
Bone scanning using the 99mTc-phosphate analogs is an established diagnostic modality and a commonly requested radioisotope examination for a variety of pathologies involving the skeleton, such as osteomyelitis, bony metastases, and occult fractures. The bone scan is one of the most commonly requested procedure in most nuclear medicine department. The images show areas of increased and de...
[ 6 ] - Accuracy of SPECT bone scintigraphy in diagnosis of meniscal tears
Introduction: Scintigraphy has been considered as a useful tool in the assessment of meniscal tears. Our objective was to assess the accuracy of single photon emission tomography (SPECT), using MRI as the gold standard, in the diagnosis of meniscal tears. Materials and Methods: Between January 2003 and February 2005, 45 patients were studied with SPECT and MRI. Results: The respective sen...
[ 7 ] - 99mtc-Ubiquicidin [29–41], a Promising Radiopharmaceutical to Differentiate Orthopedic Implant Infections from Sterile Inflammation
Ubiquicidin (UBI) [29-41] is a synthetic cationic antimicrobial peptide that preferentially binds to bacterial cell membrane at the site of infection. We aimed to assess diagnostic value of 99mTc-UBI [29-41] as a radiopharmaceutical in differentiation of bacterial infection from sterile inflammation in suspected orthopedic implants. Nine patients suspected for orthopedic implant infection, all ...
