Orbital Emphysema
Orbital emphysema (/ˈɔː(r)bɪt(ə)l ˌemfɪˈsiːmə/, also known as pneumo-orbit) is a medical condition that refers to the trapping of air within the loose subcutaneous around the Orbit (anatomy), orbit that is generally characterized by sudden onset swelling and Bruise, bruising at the impacted eye, with or without Visual impairment, deterioration of vision, which the severity depends on the density of air trapped under the orbital soft tissue spaces. It is most commonly result from forceful Sneeze, sneezing, Nose-blowing, nose blowing, or coughing among patients with a history of periorbital trauma or orbital fractures that happened several hours-days in advance. Rare occasions have also been reported in relation to individuals with no traumatic past events that include: infection, esophageal rupture, postoperative complications, Barotrauma, pulmonary barotrauma, with the same predisposing factors (Sneeze, sneezing, Nose-blowing, nose blowing, or coughing). A four-stage syst ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
CT Scan
A computed tomography scan (CT scan; formerly called computed axial tomography scan or CAT scan) is a medical imaging technique used to obtain detailed internal images of the body. The personnel that perform CT scans are called radiographers or radiology technologists. CT scanners use a rotating X-ray tube and a row of detectors placed in a gantry (medical), gantry to measure X-ray Attenuation#Radiography, attenuations by different tissues inside the body. The multiple X-ray measurements taken from different angles are then processed on a computer using tomographic reconstruction algorithms to produce Tomography, tomographic (cross-sectional) images (virtual "slices") of a body. CT scans can be used in patients with metallic implants or pacemakers, for whom magnetic resonance imaging (MRI) is Contraindication, contraindicated. Since its development in the 1970s, CT scanning has proven to be a versatile imaging technique. While CT is most prominently used in medical diagnosis, ...
