Porosity of polypropylene samples was investigated by applying X-ray micro-computed tomography (micro-CT), which is getting more and popular as a non-destructive method. Microspheres were applied blowing agent at three concentrations: 3%, 6% 9% weight. Tensile testing specimens obtained injection molding technology its central, measuring part examined micro – CT. Results compared to porosity ca...

Bone's microporosity plays important biological and mechanical roles. Synchrotron radiation micro-computed tomography (SR CT) is considered the gold standard when evaluating osteocyte lacunae, vascular channels and their three-dimensional (3D) distribution, yet it is a rather exclusive technique. Here, we explored nondestructive desktop micro-computed tomography (desktop CT) as an alternative...

objectives: accurate localization of the inferior alveolar canal (iac) is extremely important in some dental treatments. anatomical variation of the canal means that it can be difficult to locate. the purpose of this study was to assess the relationship of the gonial angle (ga) size and iac position using cone beam computed tomography (cbct). materials and methods: in this in vitro study, 61 dr...

the ribs are essential structures of the osseous thorax that provide certain significant information and aid interpretation of radiologic images in daily routine practice. intrathoracic rib is a rare congenital anomaly that is usually discovered incidentally, but may cause in vain interventions in case of being unaware. we herein report an intrathoracic rib in a girl whose chest x-ray was stran...

osteoma is a benign, slow-growing osteogenic tumor that sometimes arises from the craniomaxillofacial region, such as the sinus, temporal or jaw bones. osteoma consists of compact or cancellous bone that may be peripheral, central or extraskeletal type. peripheral osteoma arises from the periosteum and is commonly a unilateral, pedunculated mushroom-like mass. peripheral osteoma of the mandible...

abnormal elongation of the mandibular coronoid process is rare and its etiology is not yet elucidated. the aim of this report is to demonstrate and discuss the relationship between elongated mandibular coronoid process and limitation of mouth opening with cone beam computed tomography. although the clinical characteristic of elongation of the coronoid process is mandibular limitation, in this r...

primary pancreatic leiomyosarcomas are rare malignant neoplasms with an aggressive course and a large size. a 56-year-old woman presented with an 8-year history of abdominal pain. multislice computed tomography revealed a large heterogeneous mass with necrotic, calcified and macroscopic fatty areas. the tumor was excised. histopathological evaluation revealed leiomyosarcoma of the pancreas. if ...
