Background: malignant pleural mesothelioma (MPM) is uncommon neoplasm arising from mesothelial cells of the pleura. The most important etiologic agent is typically related to exposure to minerals fibers such as asbestos and erionite. Computed tomography (CT) plays essential role in characterization, diagnosis and staging of MPM. Objectives: to determine the value of CT scan in characterization ...

A review of staging investigations in the preoperative evaluation of mediastinal involvement in primary bronchial carcinoma is presented. The following conclusions are offered as guidelines for the use of mediastinal staging procedures in clinical practice: Surgical staging methods have the over-riding advantage of superior specificity over indirect imaging techniques. Where 67Ga-imaging or CT ...

NPC is clinically staged according to the International Union Against Cancer (UICC) and American Joint Committee on Cancer (AJCC) staging system (Table 1). Routine staging procedures include history, physical examination including cranial nerve examination, complete blood cell count, serum biochemistry (including liver function test), chest X-ray, nasopharyngoscopy, computed tomography (CT) sca...

Background. The objective of this study is to assess the accuracy of pre- and posttherapeutic staging of endolaryngeal cancer involving anterior commissure. Materials and Methods. 127 patients were included in this retrospective study, and laryngectomy (partial or radical) was achieved in all of them. Initial radioclinical evaluation (cT) was performed (endoscopy-CT scan) and compared with post...

BACKGROUND AND OBJECTIVES In order to receive the most appropriate therapy, patients with Hodgkin's lymphoma (HL) must be accurately stratified into different prognostic staging groups. Computed tomography (CT) plays a pivotal role in the conventional staging. The aim of the present study was to investigate the value of positron emission tomography using 2-[18F]fluoro-2-deoxy-D-glucose (FDG-PET...

introduction in ct imaging, metallic implants inside the tissues cause metal artifact that reduce the quality of image for diagnosis. in order to reduce the effect of this artifact, a new method with more appropriate results has been presented in this research work. materials and methods the presented method comprised of following steps: a) image enhancement and metal areas extraction, b) sinog...

Headache is a common symptom, with a lifetime prevalence of over 90% of the general population in the United Kingdom (UK). It accounts for 4.4% of consultations in primary care and 30% of neurology outpatient consultations. Neuroimaging is indicated in patients with red flag features for secondary headaches. The guidelines recommend CT or MRI scan to identify any intracranial pathology. We pres...

FDG-PET/CT is a widely established imaging modality for staging, restaging and monitoring therapy response in lymphoma patients. Progressive transformation of germinal centres (PTGC) is a benign condition presenting characteristically as asymptomatic lymphadenopathy. This paper presents a case of a 53-year-old man with a history of Hodgkin's disease (HD) whose F(18) FDG-PET/CT scan showed high ...

Thirty-six year old male patient with pathological fracture of the left tibia underwent intramedullary and soft tissue curettage. The histopathological examination revealed diffuse large B cell lymphoma. The patient underwent F18-FDG PET-CT scanning for initial staging. FDG PET-CT scan revealed hypermetabolic lesions at the left tibia and in bilateral kidneys. After the systemic chemotherapy an...

prognosis after surgical resection can be expected in comparison with patients with preoperative confirmed N2 disease [8]. An additional advantage of the PET scan in comparison with mediastinoscopy is that the PET scan can indicate suspected lymph nodes in stations not amenable to mediastinoscopy (eg, paraesophageal or supraclavicular). Staging of the mediastinum using positron emission tomogra...
