PURPOSE The objective of this study was to compare the diagnostic value obtained using single-photon emission computed tomography (SPECT)/spiral computed tomography (CT) with Tc-99m methylene-diphosphonate with that obtained using SPECT alone in patients with spinal lesions. METHODS This was a retrospective study of 56 patients who underwent planar(More)
Primary PSC in the lung is a rare malignant cancer that represents a particularly aggressive subtype of non-small cell lung carcinomas (NSCLC) containing sarcoma or sarcoma-like components with spindle or giant cell features. The medical literature referring to imaging characteristics by fluorine-18-fluorodeoxyglucose (¹⁸F-FDG) positron emission(More)
Primary liver carcinosarcoma is a very rare, malignant neoplasm that is concomitantly composed of a mixture of sarcomatous and carcinomatous elements. In the present study, an initial staging FDG PET/CT showed intense FDG uptake in a patient with liver carcinosarcoma composed of hepatocellular carcinoma and rhabdomyosarcoma. Two months after surgical(More)
UNLABELLED Primary pulmonary artery sarcoma (PAS) is a rare and highly lethal tumor. Here, we report a case of a 53-year-old female with PAS who was initially diagnosed with chronic pulmonary thromboembolism (PTE) based on the results of a transthoracic Doppler echocardiogram, a contrast-enhanced computed tomography angiography, and a ventilation/perfusion(More)
OBJECTIVE Metastases and benign conditions of spine are common, however, the diagnoses of imaging modalities in the nature of spinal lesions are difficult, especially for the solitary lesions in spine. This study aims to retrospectively evaluate the diagnostic value of single photon emission computed tomography (SPECT)/spiral computed tomography (CT) in(More)
Gastric Schwannoma is a rare benign mesenchymal tumor that accounts for only 0.2% of all gastric tumors. The current study presents a case of gastric Schwannoma misdiagnosed as malignant gastrointestinal stromal tumor (GIST) by esophagogastroduodenoscopy, endoscopic ultrasonography, and contrast-enhanced or not enhanced and (18)F-FDG PET/CT imaging.
PURPOSE The aim of this study was to investigate the added value of single-photon emission computed tomography (SPECT)/spiral computed tomography (CT) versus SPECT alone in the differential diagnosis of solitary spinal lesions in patients with extraskeletal malignancies. MATERIALS AND METHODS A total of 90 patients who had a solitary spine 'hot spot' that(More)
In order to realize accurate localization and precise evaluation of vulnerability of atherosclerotic plaques via dual-modal imaging, gold nanoparticles (GNPs) were firstly caped with a thin amino-PEGs cover and then conjugated with the targeting molecular Annexin V and radionuclide Tc-99m simultaneously to form SPECT/CT imaging probe targeting apoptotic(More)
