Radiographic imaging is one of the greatest investigative tools that are used in medical sciences since ages. There is an important role of imaging in staging, during treatment planning, and post-treatment follow up of patients with head and neck cancer. To design an effective treatment strategy, two tasks are very important which are accurate staging and timely assessment of the cancer.
Through the use of a cone shaped X-Ray beam that rotates degrees around the patient head similar to panoramic exposure. W hat is C BCT? Cone beam CT is a tomographic scanning technology that can scan and acquire a specified volume of the patient's head and generate a 3D data set at much lower radiation doses than their medical CT counterparts.
Computed tomography CT is today commonly used in imaging of the maxillofacial area. Conventional CT examinations are usually performed in medical X-ray departments. However, a relatively new technique named cone-beam computed tomography CBCT or digital volume tomography DVT has now also become available for dental purposes.
Standardization of the medical image files as digital imaging and communications in medicine DICOM has made possible the development of software that can evaluate, manipulate, and reformat medical images that make them easily converted to file formats to fabricate medical models and custom devices from industrial manufacturing processes. These standards are applied to all medical capture devices to include magnetic resonance, ultrasound, conventional computed tomography CT scans, and dental cone beam CT CBCT ensuring that all of these files are compatible with picture archiving and communication systems, which store and provide access from multiple modalities. Cephalometric radiographs, pantographic radiographs, and computed tomography CT have historically been used for imaging for reconstruction of the craniofacial structures.
Oral Maxillofacial Radiology OMR is a dental specialty that deals with the use of X-rays radiographic imaging to diagnose and treat diseases or disorders of the mouth, teeth, face and jaw the maxillofacial region. OMR utilizes a combination of standard film X-rays, and digital and panoramic X-rays radiographs providing a panoramic view of upper and lower dental arches and the temporomandibular joints. OMR also involves the use of radiation and radioactive materials to treat diseases of the mouth and jaws.
Mountain Medical offers maxillofacial and sinus CT imaging face imagingwhich has become the key diagnostic modality in the evaluation of facial trauma. Maxillofacial CT imaging evaluate the bones of the face including the orbits, sinuses, mandible jawand teeth. This exam can detect fractures, orbit injury, sinus infections, eye infections, and tumors of the face and nearby tissues.
Peer Reviewer: John P. Emergency department ED practitioners commonly encounter patients with maxillofacial trauma. ED physicians must use all of their training and skills to provide the initial stabilization and make an accurate and timely diagnosis of the spectrum of injuries that commonly occur.
The invention of computed tomography CT technique revolutionized diagnostic imaging. Compared to conventional X-ray imaging procedures, CT involves higher radiation doses. The detector system performs one rotation around the patient, producing a series of 2D images which are then reconstructed in a 3D data set. The contemporary knowledge regarding CBCT and its proper application guides the practitioner for improvement in diagnostic purposes and treatment planning.
Computed tomography CT of the sinuses uses special x-ray equipment to evaluate the paranasal sinus cavities — hollow, air-filled spaces within the bones of the face surrounding the nasal cavity. CT scanning is painless, noninvasive and accurate. It's also the most reliable imaging technique for determining if the sinuses are obstructed and the best imaging modality for sinusitis.
