The aim is to assess the influence of fabrication techniques—conventional (CN), CAD-CAM (CC), and 3D printing (3D)—on marginal fit, adaptation, surface roughness, wear interim restorations crowns. Thirty crowns were fabricated using CN, CC, techniques. Sixty discs evaluate roughness properties, with 10 disc samples in each group (n = 10). Internal adaptation integrity analyzed micro CT detect m...

BACKGROUND Adenocarcinoma with lepidic growth pattern presents as a ground glass nodule (GGN) on high resolution computed tomography (CT), whereas peripheral pulmonary squamous cell carcinoma (SCC) usually presents as a solid nodule. We herein report a rare case of pulmonary SCC extending along the alveolar lumen representing as a GGN on a CT scan in a patient with pneumoconiosis. CASE PRESEN...

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...

The computed tomographic (CT) findings in six cases of neonatal herpes simplex encephalitis (HSE) are reviewed and compared with previous reports. The diagnoses were made on the basis of isolation of the virus from a brain biopsy specimen in one case, from cerebrospinal fluid in two cases, from tracheal aspirate in one case, and on clinical grounds in two cases. Five infants survived; all had s...

This work describes a novel method for statistical analysis of multi-material components. The application scenario is industrial 3D X-ray computed tomography, emphasizing metrology of artefact affected plastics-metal components. The presented work makes use of dual energy CT data acquisition for artefact reduction, in order to optimize CT scans of multi-material components. Using statistical an...

BACKGROUND Pleural mesothelioma is a very rare neoplasm; especially the local form. The diagnostics is difficult and the prognosis unfavourable. CASE REPORT We presented a case of a man with dyspnoea and cough. His chest radiogram showed hydrothorax on the left side. Neither the examinations of the pleural liquid, nor the CT-guided fine needle biopsy established the diagnosis. CT showed featu...

OBJECTIVE We wanted to clarify the relationship between the visibility of air cysts on CT images, the CT slice thickness and the size of the air cysts, with contact radiographs as the gold standard, for the accurate evaluation of honeycomb cysts. MATERIALS AND METHODS An inflated and fixed autopsied lung having idiopathic interstitial pneumonia was evaluated. The corresponding air cysts were ...

A 70 year old male with a history of inoperable pancreatic cancer with peritoneal metastases was evaluated by FDG PET/CT imaging for disease extent and therapy response after 4 cycles of chemotherapy. PET/CT demonstrated mildly increased uptake at the primary site within the pancreatic neck and in the peritoneum. An unexpected finding involved increased uptake in the right inguinal canal region...

Background: F-FDG PET/CT is widely utilized in the management of cancer patients. The aim of this paper was to comprehensively describe the specific methodology utilized in our single-institution cumulative retrospective experience with a multimodal imaging and detection approach to F-FDG-directed surgery for known/suspected malignancies. Methods: From June 2005-June 2010, 145 patients were inj...

With the gradual increase of coal mining intensity, many pillars need to be left near stope. The stability composite structure and their overlying strata determines safety whole stope surface. This paper conducts uniaxial compression tests on coal-rock structures with same lithology height ratio finds structure’s mechanical properties failure characteristics have greater discreteness. Combining...
