The invention of computed tomography (CT) technique revolutionized diagnostic imaging. Compared to conventional X-ray imaging procedures, CT involves higher radiation doses. Recently, cone-beam CT (CBCT) specifically designed for maxillofacial imaging was introduced. CBCT technique is based on a cone-shaped X-ray beam centered on a twodimensional (2D) detector. The detector system performs one ...
Multiple myeloma is a monoclonal malignant proliferation of plasma cells that causes osteolytic lesions in the vertebrae, ribs, pelvic bone, skull and jaw. We report a case of a 66 year-old-woman with pain and right facial swelling. Radiographic examination showed a well-defined radiolucent lesion in left posterior mandible. An incisional biopsy was performed and histopathological examination r...
i ntroduction: the incidence and etiology of maxillofacial fractures vary widely between different countries. understanding the cause and pattern of these injuries can assist in establishing clinical and research priorities for more effective treatment and prevention of maxillofacial injuries. the study aimed to evaluate the etiology and pattern of maxillofacial fractures in trauma pa...
Various kinds of diseases may be found in the oral and maxillofacial regions and various modalities may be applied for their diagnosis, including intra-oral radiography, panoramic radiography, ultrasonography, computed tomography, magnetic resonance imaging, and nuclear medicine methods such as positron emission tomography. Of these modalities, ultrasound imaging is easy to use for the detectio...
background and aims. the imaging techniques commonly used for foreign body detection include plain radiography, xeroradiography, computed tomography (ct) scans, magnetic resonance imaging (mri) and ultrasonography. the aim of the present study was to compare cone-beam computed tomography (cbct) with conventional ct scan in determination of the exact location of a foreign body in the maxillofaci...
Cone beam computed tomography (CBCT, also referred to as C-arm computed tomography [CT], cone beam volume CT, or flat panel CT) is a medical imaging technique of X-ray CT where the X-rays are divergent, forming a cone.[1] CBCT systems have been designed for imaging hard tissues of the maxillofacial region. CBCT is capable of providing sub-millimeter resolution in images of high diagnostic quali...
This study aimed to describe the imaging aspects of a concha bullosa discovered incidentally by means cone-beam computed tomography (CBCT) imaging. A female patient underwent CBCT exam, and bilateral extensive pneumatization middle was verified, presenting larger dimension right side deviated septum. The reported nasal obstruction loss smell. for covering maxillofacial region allowed discovery ...
