Estimate bowtie filter shape in PET/CT scan with TLD
Introduction: The CT machine utilizes a bowtie filter to shape the X-ray beam and remove lower energy photons. Configuration of this bowtie filter is complex and its geometry is often not available in detail. It causes the CT dose index (CTDI) be with the different values in measurement versus Monte Carlo simulation studies and other analytical calculations. It is important esp...
متن کامل18F-FDG PET/CT in pleural epithelioid hemangioendothelioma
Pleural epithelioid hemangioendothelioma (EHE) is a rare malignancy of vascular-endothelial origin with non-specific symptoms and an unpredictable outcome. Diagnosis of this condition by imaging modalities is challenging, and no standard therapeutic approaches have been established in this regard. In this paper, we described the case of a patient with a low-grade fever, coughing and chest pain ...
متن کامل18FDG PET/CT in pulmonary carcinosarcoma and brain metastasis
Carcinosarcoma is a rare type of cancer that is composed of a mixture of sarcomatous and carcinomatous elements. Pulmonary carcinosarcoma has a 25% five-year survival rate with a prognosis poorer than other non-small cell lung carcinomas. Herein, we report a case of pulmonary carcinosarcoma and its 18F-FDG PET/CT findings. A 61-year-old male patient presented with brain symptoms, including hea...
متن کاملPET/CT in Oncology
Positron emission tomography (PET) is a molecular imaging method that images the human body non-invasively from a functional, biochemical perspective. PET is extraordinarily sensitive and can detect minute (femtomolar) quantities of radioactive tracers. However, because of photon scattering, the images do not have as high spatial resolution as CT or MRI nor do they provide much anatomical infor...
متن کامل18F-FDG PET/CT in Neurolymphomatosis: Report of 3 Cases
Neurolymphomatosis is a rare manifestation of non-Hodgkin lymphoma characterized by infiltration of peripheral nerves, nerve roots, plexus and cranial nerves by malignant lymphocytes. This report presents positron emission tomography/computed tomography (PET/CT)imaging with 2-deoxy-2-18F-fluoro-D-glucose (18F-FDG) in 3 cases of non-Hodgkin lymphoma with nerve infiltration, including one newly d...
