A 24-year-old male, with no medical history, noticed a gradual increase in the size of his left testicle over a period of six months. He consulted a physician because he had headaches, vomiting, fatigue, and mild dyspnea. On physical examination, he was found to be normotensive, with oxygen saturation of 99%. His relevant laboratory data were: Hematocrit 35.8%, LDH 2,345 IU/l (NV 210-420 IU/l),...

BACKGROUND It can be difficult to perform CT guided biopsy of small pulmonary nodules especially if the position is behind a costa or close to the diaphragm and respiratory movements may hamper the procedure. During apneic oxygenation with a pulmonary standstill these movements can be hindered. METHODS Six patients with decreased lung function and suspicious lung nodules are presented. Under ...

The paper deals with modeling the liver perfusion intended to improve quantitative analysis of the tissue scans provided by the contrast-enhanced computed tomography (CT). For this purpose, we developed a model of dynamic transport of the contrast fluid through the hierarchies of the perfusion trees. Conceptually, computed time-space distributions of the so-called tissue density can be compared...

This paper explores the usage of microfocus X-ray computed tomography (CT) for visualization and quantification of diffusion phenomena in cracked concrete. Mortar specimens of varying shapes (prismatic and cylindrical), crack types (artificial and splitting tensile), and binder compositions (OPC and fly ash) were prepared. Cesium carbonate (Cs2CO3) was used as a tracer in the diffusion test bec...

In patients with COPD, CT assessment of emphysema and airway disease is known to be associated with lung function and 6-minute walk distance. However, it remains to be determined whether low attenuation area (LAA) on CT is associated with aerobic capacity assessed using cardiopulmonary exercise testing (CPET). In this prospective observational study, we repeatedly conducted high-resolution CT a...

Introduction: Robust data of CRP is available in bacterial infection, and now it can be utilized Covid- 19 pneumonia pandemic initial assessment severity planning treatment. Materials Methods: Multicentric, prospective, observational interventional study conducted during July 2020 to May 2021 included 1000 Covid-19 cases confirmed with RT PCR. All were assessed lung involvement documented categ...

We hypothesised that biomass smoke exposure is associated with an airway-predominant chronic obstructive pulmonary disease (COPD) phenotype, while tobacco-related COPD is associated with an emphysema-predominant phenotype. In this cross-sectional study, female never-smokers with COPD and biomass exposure (n=21) and female ex-cigarette smokers with COPD without biomass exposure (n=22) completed ...

The growing field of ocean acidification research is concerned with the investigation of organism responses to increasing pCO2 values. One important approach in this context is culture work using seawater with adjusted CO2 levels. As aqueous pCO2 is difficult to measure directly in smallscale experiments, it is generally calculated from two other measured parameters of the carbonate system (oft...

BACKGROUND AND PURPOSE Intracranial lipomas are uncommon congenital malformations that most often are asymptomatic. A rare subset of intracranial lipomas arises within the vestibule of the inner ear, which can cause sensorineural hearing loss. We present the CT and MR imaging characteristics of lipomas within the vestibule of the inner ear and propose a pathogenetic mechanism for this malformat...
