During the study of chest using positron emission tomography (PET) with [18F]fluoro-2-deoxy-d-glucose (FDG), a significant myocardial FDG uptake can prevent detection of the lesion that is located either behind or closely attached to the heart border. Two well-known and possible factors of myocardial FDG uptake are blood glucose level and fasting duration(More)
PURPOSE The aim of this study was to evaluate the effectiveness of positron emission tomography (PET) using 18-fluoro-2-deoxyglucose (FDG) to detect recurrent nasopharyngeal carcinomas (NPC) when magnetic resonance imaging (MRI) findings are indeterminate. PATIENTS AND METHODS After radiotherapy, 28 NPC patients with indeterminate MRI findings were(More)
To evaluate the clinical value of positron emission tomography (PET) with 18F-fluoro-2-deoxyglucose (FDG) in recurrent colorectal cancer, the records of 33 patients who underwent 34 FDG-PET scans were reviewed and compared with computed tomography (CT) and carcinoembryonic antigen (CEA). The final diagnosis was based on operative, histopathological findings(More)
OBJECTIVES Systemic lupus erythematosus (SLE) can affect multiple organs. Coronary artery disease has received increasing recognition as a major cause of morbidity and mortality in SLE in recent years. The purpose of this study was to evaluate the utility of technetium-99m sestamibi single-photon emission computed tomography ((99m)Tc-sestamibi SPECT) in the(More)
The aim of this study was to investigate the relationships among technetium-99m tetrofosmin (Tc-TF) accumulation in untreated small cell lung cancer (SCLC), the expression of P-glycoprotein (Pgp) and multidrug resistance related protein-1 (MRP1), and the response to chemotherapy in patients with untreated SCLC. Thirty patients with SCLC were studied with(More)
OBJECTIVE Technetium-99m ethyl cysteinate dimer (99mTc ECD) single photon emission computed tomography (SPECT) of the brain was used to detect abnormal regional cerebral blood flow (rCBF) in patients with primary Sjögren's syndrome (pSS) and normal findings on brain magnetic resonance imaging (MRI). METHODS (99m)Tc ECD brain SPECT was performed to detect(More)
BACKGROUND Systemic lupus erythematosus (SLE) can affect every organ. Involvement of the lungs in this disease is a significant cause of morbidity and mortality. OBJECTIVES To assess pulmonary vascular endothelium damage in SLE by lung uptake of technetium-99m hexamethylpropylene amine oxime ((99m)Tc-HMPAO). METHODS Lung uptake of (99m)Tc-HMPAO was(More)
Our aim was to use technetium-99m tetrofosmin (Tc-TF) uptake in non-small cell lung cancer (NSCLC) for predicting the chemotherapeutic response of NSCLC to paclitaxel and to compare the results with the expression of multidrug resistance (MDR) - P-glycoprotein (Pgp). Twenty patients with advanced NSCLC were enrolled in this study before chemotherapy with(More)
In vitro studies have shown that technetium-99m tetrofosmin (Tc-99m TF) is a transport substrate for the P-glycoprotein (Pgp) pump. Therefore, Tc-99m TF uptake of tumors can be used to predict chemotherapy response in lung cancers. However, whether lung resistance-related protein (LRP) expression affects tumor accumulation and efflux of Tc-99m TF in lung(More)
The establishment of new tumor marker combinations including strong lead-time effects in detecting recurrent cervical cancer appears to be warranted. This retrospective study includes 50 patients with recurrent squamous cell cervical cancer after operation or radiotherapy. The serial serum levels of the tumor markers tissue polypeptide specific antigen(More)
