Three-dimensional terahertz computed tomography has been used to investigate dried human bones such as a lumbar vertebra, a coxal bone, and a skull, with a direct comparison with standard radiography. In spite of lower spatial resolution compared with x-ray, terahertz imaging clearly discerns a compact bone from a spongy one, with strong terahertz absorption as shown by additional terahertz tim...

background: langerhans' cell histiocytosis (lch) is a reactive proliferative disease of unknown pathogenesis characterized by proliferation of langerhans cells. involvement of bone marrow (bm), liver and lung are related to high risk factors and poor survival. the aim of this report is to highlight the clinical and haematological findings of 5 cases of lch with bm infiltration which may help to...

A 23-year-old female patient presented with diffuse swelling causing intermittent pain involving the left side of face that had been present for over 10 years. Extra-oral examination revealed expansile lesions in maxilla and mandible, appeared mixed radiolucent-radiopaque on panoramic radiography. The maxillary lesion resulted opacification sinus. mandible trabecular bony changes larger radiolu...

The coronavirus pandemic has posed a challenge to health-care workers, who are at high risk for exposure the disease. However, they also face of infection due presence asymptomatic carriers. aim this study was demonstrate necessity standard radiography protocol fracture surveillance and good history taking physical neurological examinations, especially in pediatric patients with minor head inju...

BACKGROUND AND PURPOSE Platybasia, or abnormal obtuseness of the basal angle, was first measured on plain skull images. At present, evaluation of the brain and skull more commonly involves CT and MR imaging. We evaluated a new MR imaging method of evaluating platybasia. METHODS We retrospectively evaluated midline sagittal MR images in 200 adults and 50 children. The basal angle of the skull ...

Background: The basic challenge with computed radiography (CR) systems is the large dynamic range which provides an opportunity for radiographers to gradually increase exposure factors and still produce good image quality, a practice that can lead to dose creep. Materials and Methods: The aim of this study was to establish  the entrance skin dose (ESD) values for nine selected examinations in t...

Gorlin-Goltz syndrome (GGS) consists of ectodermal and mesodermal abnormalities. In this case report we will investigate lower extremity lesions of GGS. A 52-year-old man with GGS underwent skull and lower extremity computer tomography. Radiographic findings included cervical spondylosis, transparent areas with slurred margins, and cerebral falx calcification. Tibial and fibular specific cortic...
