Background: The role of fluorine-18 fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG-PET/CT) in the surgical approach solitary pulmonary nodule (SPN) is still debated, as increased metabolic avidity lesion was not a sure sign malignancy. purpose this study to evaluate effectiveness 18F-FDG-PET/CT characterization SPN based on analysis most recent data literature.
PURPOSE The aim of the study was to present the computed tomography (CT) and fluorine 18 (F) fluorodeoxyglucose-positron emission tomography (FDG-PET)/CT imaging findings of pulmonary mucosa-associated lymphoid tissue (MALT) lymphoma and evaluate their roles in the follow-up of this tumor. METHODS Computed tomography and FDG-PET/CT imaging findings of 18 cases of pathologically proven pulmona...
Introduction: The aim of the current study was to investigate the effects of X-ray radiation on some hematological parameters, morphology of red blood cells (RBC) and erythrocyte sedimentation rate (ESR) analysis of human blood using computed tomography (CT) scanner. Material and Methods: For the purpose of the study, 5 ml of wholeblood was drawn from vein puncture of 28 healthy people and div...
Introduction: Mini Computed Tomography (mini-CT) was suggested in biomedical research to investigate tissues and small animals. We present designed and built a mini x-ray computed tomography (mini-CT) for small animals as well as industrial component imaging. Materials and Methods: The system used in this study includes a X-ray tube 20kV to 160kV and a flat pa...
A 32 year-old white man, on his return from working in Nigeria, came for an examination of 3 weeks dry cough associated with fever and asthenia . He used to swim in fresh water in the Niger River valley for 6 months. There was no evidence of malaria. Hypereosinophilia at 18.8% was found in the blood (white blood cell [WBC] = 8,399/mm 3 , eosinophils cells = 1,579/mm 3 ) and in broncho-alveolar ...
Computed tomography (CT) dosimetry normally uses an ionization chamber 100 mm long to estimate the computed tomography dose index (CTDI), however some reports have already indicated that small devices could replace the long ion chamber to improve quality assurance procedures in CT dosimetry. This paper presents a novel dosimetry system based in a commercial phototransistor evaluated for CT dosi...
Abstract We in this article have presented a review of the guideline recommendations on theranostic positron emission tomography-computed tomography (PET-CT) imaging which will be helpful to assist practitioners providing appropriate patient care. Multiple guidelines by different societies and medical associations provide standards for diagnosis, imaging, treatment cancer patients. They generat...
ABSTRACT Trauma is the most common reason of death in 1-44 years olds. In patients with multiple rtrauma, the head is the most common involved part . Car accident is the most common cause of head injury in adults. The importance of computed tomography (CT) in diagnosis of brain trauma is well estabilished and CT of the brain is a choice method. A descriptive study was carried out in 880 patie...
Background: The Diagnostic reference levels (DRLs) play a critical role in the optimization of radiation dose especially, in some conditions like pediatrics. They are useful indicators by which the radiologists can be aware of delivered excess radiation doses to the patients, and take corrective actions if necessary. In order to meet some requirements for establishing the national computed tomo...
Orbital pseudotumour is a non-specific inflammatory disease. Its highly variable clinical and radiographic presentation makes specific diagnosis difficult. This study on 31 proven cases of pseudotumour shows that unilateral involvement, retroorbital fat infiltration and enlargement of multiple extraocular muscles with involvement of the tendinous insertions are key computed tomography CT featur...
