introduction: the purpose of the present study was to evaluate the effect of prednisolone on the sensitivity of bone scanning to detect the simulated closed fracture in the rat tibia.  methods: a total number of forty eight adult, male nmri rats randomly assigned into two parts, one part for 4 and other for 8 weeks experiments. each part has been divided into four groups, one group not receivi...

osteitis fibrosa cystica is the classic patognomonic form of skeletal disease in hyperparathyroidism that characterizes with decreased cortical bone thickness compared to increased cancellous bone. we present a case of 52-year old female patient with osteolysis of the left calf on radiographic images. the bone scan detected multiple focal pathological accumulations in the skull, left tibia, bot...

metastatic survey of the patients with known primary malignancies with bone scan is one of the most common studies in nuclear medicine. unfortunately the conventional planar bone scan has a very low specificity for differentiating benign from malignant lesions especially in the spinal column. in this study, we compared the specificity of spect imaging and conventional planar bone scan. we studi...

Introduction: Chronic abdominal pain in children is mostly functional, but association with alarm symptoms such as recurrent vomiting, it necessary to determine proper tests for the diagnosis of probable underlying organic problems. Case Presentation: Four patients chronic refractory and nonspecific gastrointestinal presented our tertiary pediatric center. After thorough medical psychological i...

The intrathoracic kidney is one of the rare causes congenital ectopic kidney. present study discusses a case referred to our clinic with pre-diagnosis renal agenesis and diagnosis 9-year-old patient who applied complaining abdominal pain. left could not be shown in ultrasonography for patient's In Tc-99m dimercaptosuccinic acid (DMSA) scintigraphy performed on this, was detected far above its n...

OBJECTIVE To determine use of early Tc-99m dimercaptosuccinic acid scintigraphy in screening for vesicoureteral reflux following first febrile urinary tract infection. METHODS 43 children (1 mo-5 yr) with first febrile urinary tract infection underwent micturating cystourethrography, abdominal sonogram and early dimercaptosuccinic acid scintigraphy. RESULTS Early dimercaptosuccinic acid sci...

A 79-year-old man with melena was suspected of having small bowel bleeding because upper and lower endoscopic findings were negative. Technetium-99m-labeled red blood cell (Tc-99m-RBC) scintigraphy was performed by arterial injection of a radiotracer from the superior mesenteric artery (SMA) after angiography. Extravasation was seen in the ileum by scintigraphy although angiography was negative...

introduction: the relationship between depression and coronary artery disease is well established; however assessment of this relationship using functional and semi-quantitative imaging (myocardial perfusion scintigraphy) was lacking. the aim of this study was to assess the relationship between the severity of depression and the severity of myocardial perfusion abnormality. methods: patients we...

OBJECTIVES The aim of this study is to evaluate the usefulness of gastroesophageal reflux (GER) scintigraphy using the knee-chest (KC) position for the diagnosis of gastroesophageal reflux disease (GERD). METHODS The study subjects were 37 patients with GERD and 8 healthy volunteers (control group). Endoscopically observed esophageal mucosal breaks were evaluated with the Los Angeles classifi...

Detection of bone metastases in patients with lung cancer has important clinical significance and therapeutic implications, since it causes relevant changes in the patients’ treatment. This study compared the efficacies of 18F-fludeoxyglucose positron emission tomography (18F-FDG PET)/CT, and 99mTc bone scintigraphy [planar and single photon emission CT (SPECT))for detection of bone metastases ...
