background: to reduce uncertainties of patient positioning, the computerized tomography (ct) images acquired at the treatment planning time can be compared with those images obtained during radiation dose delivery. this can be followed during dose delivery procedure as image guided radiotherapy (igrt) to verify the prescribed radiation dose delivery to the target as well as to monitor radiation...

background: this study set out to evaluate the utility of cerebrovascular virtual non-contrast (vnc) scans. materials and methods: conventional non-contrast (cnc) and dual-energy computed tomography angiography (de-cta) head scans were conducted on 100 subjects, of which 46 were normal, 15 had parenchymal hematomas of the brain, 13 had ischemic infarction, 22 had tumors, and 4 had calcified les...

conclusions recent treatment, in addition to age, gender and daylight duration were proved as strong independent determinants on bat development and the level of metabolic activity at [18 f] dg pet/ct and should be considered as an important confounding factor in future researches. results one-hundred eighteen studies were recognized to demonstrate foci of fdg bat uptake (3.1%, mean age: 22.7 y...

background: actinomycosis is an indolent, slowly progressive infection caused by non acid fast, gram positive, anaerobic or microaerophilic bacteria. the most common site of actinomycosis infection is cervicofacial region. bacteriologic identification from infected site or detection of sulfur granules confirms the diagnosis. we report a rare case of simultaneous infection of larynx and lungs ac...

Assuming that ORD is ! + !-Erdd os we show that if a class forcing amenable to L (an L-forcing) has a generic then it has one deenable in a set-generic extension of LO # ]. In fact we may choose such a generic to be periodic in the sense that it preserve the indiscernibility of a nal segment of a periodic subclass of the Silver indiscernibles, and therefore to be almost codable in the sense tha...

The method of Deibler, Holmes, Campbell, and Gans (1959) is a quick, accurate, and reliable method for the determination of oxygen saturation. The results should be calibrated against those obtained by the Van Slyke method, and the setting, sensitivity, and reliability of the spectrophotometer should be carefully established. This is especially necessary to meet the stringent requirements for a...

The identification of microscale oil structures formed from deposited droplets on the filter front face a coalescence medium is essential to understand initial state filtration process. Using µ-CT imaging and deep learning tool for segmentation, this work presents novel approach visualize identify as fibers or sails between adjacent different sizes, shapes orientations. Furthermore, local globa...

The coronavirus is a disease that affects the respiratory system, it comes from SARS-CoV-2 virus belongs to Beta group and currently cause of high mortality rate worldwide. diagnosis through images oropharyngeal nasopharyngeal tests helps in recognition this condition. We present clinical case 74-year-old patient with diarrhea, dyspnea, cough, establishing COVID-19. found paraclinical parameter...
