Her technetium-99m diethylenetriaminepentaacetic acid (99mTc-DTPA) radioaerosol inhalation lung scintigraphy (May 21, 2008) revealed marked hypoventilation of the left lung and retention of the radiotracer in the right peri-hilar region, suggestive of a parenchymal process. The use of 99mTC human albumin macroaggregates (99mTC MAA) revealed no perfusion in the left lung and perfusion defects in...

INTRODUCTION Due to limitation of colonoscopy in assessing the entire bowel and patients' intolerance in inflammatory bowel disease (IBD), in the current study, we aimed to prospectively compare the accuracy of 99mTc(V)-dimercaptosuccinic acid (DMSA) and fecal calprotectin with ileocolonoscopy as new methods for localizing inflammations. METHODS Current prospective study conducted between 2012 ...

Aim: The aim of this study was to assess the role of labelled leukocyte scintigraphy in the diagnosis and monitorization of response to therapy of patients with active bronchiectasis. Material and methods: Twenty patients underwent 99mTechnetium hexamethylpropyleneamine oxime (99mTc-HMPAO) labelledwhite blood cell (WBC) scintigraphy. A second scintigraphywas performed in 13 patients at 10 day o...

  Objective(s): The objective of this study was to evaluate the performance and utility of 99mTc HYNIC-TOC planar scintigraphy and SPECT/CT in the diagnosis, staging and management of gastroenteropancreatic neuroendocrine tumors (GPNETs). Methods: 22 patients (median age, 46 years) with histologically proven gastroentero-pancreatic NETs underwent 99mTc HYNIC-TOC whole body scintigraphy and regi...

UNLABELLED In patients with progressive metastatic (or recurrent) differentiated thyroid carcinoma (DTC) who do not respond to radioiodine therapy or do not show uptake on radioiodine scintigraphy, treatment options are few. Because these tumors may express somatostatin receptors, peptide receptor radionuclide therapy might be effective. We evaluated the therapeutic efficacy of the radiolabeled...

Bone scintigraphy with 99mTc diphosphonates may exhibit extraosseous lesions in addition to metastatic lesions. Multiple factors can affect extraosseous 99mTc methylene diphosphonate (MDP) uptake. Similar uptake pattern of 99mTc MDP and fluorine-18 fluorodeoxyglucose (18F FDG) in hepatic metastasis was not already notified. In our case, initial tumor necrosis and subsequent intracellular calcif...

BackgroundEarly diagnosis of transthyretin cardiac amyloidosis (ATTR-CA) is important. The aim this study was to validate the ‘Kumamoto criteria’ for prediction technetium-99m pyrophosphate (99mTc-PYP) scintigraphy positivity.MethodsOne hundred fifty patients (median age: 79.4 years, 117 males) with possibility ATTR-CA who underwent 99mTc-PYP were assessed. We divided into 4 groups (groups scor...

STUDY OBJECTIVES Paraquat, a widely used herbicide, has been shown to cause severe and often fatal pulmonary fibrosis in humans and laboratory animals. Although paraquat is known to be directly cytotoxic to lung parenchyma, changes in routine lung scintigraphy results after acute paraquat intoxication have not been reported. The objective of this project was to investigate changes in lung venti...

objective(s): the objective of this study was to evaluate the performance and utility of 99mtc hynic-toc planar scintigraphy and spect/ct in the diagnosis, staging and management of gastroenteropancreatic neuroendocrine tumors (gpnets). methods: 22 patients (median age, 46 years) with histologically proven gastroentero-pancreatic nets underwent 99mtc hynic-toc whole body scintigraphy and region...

The purpose of the study was; (i) to determine whether 123I-MIBG scintigraphy is sensitive for detection of amiodarone induced pulmonary toxicity (AIPT) and (ii) to compare it with 99mTc-DTPA radioaerosol. Twelve white New Zealand rabbit with initial mean body weight 4.24 +/- 0.47 g were divided into two groups. AIPT group (n = 7) was administered amiodarone (20 mg/kg BW). The control group (n ...
