Contrasted CT scans of the chest are usually used to confirm diagnosis of for lung cancer and abscesses, as well as to assess lymph node status at the hila and the mediastinum. CT pulmonary angiogram , which uses time-matched ("phased") protocols to assess the lung perfusion and the patency of great arteries and veins , particularly to look for ...
The CPT code revisions in 2013 were part of a periodic five-year review of codes. Some psychotherapy codes changed numbers, for example 90806 changed to 90834 for individual psychotherapy of a similar duration. Add-on codes were created for the complexity of communication about procedures.
Klippel–Feil syndrome (KFS), also known as cervical vertebral fusion syndrome, is a rare congenital condition characterized by the abnormal fusion of any two of the seven bones in the neck (cervical vertebrae). [1]: 578 It can result in a limited ability to move the neck and shortness of the neck, resulting in the appearance of a low hairline ...
Low-dose high-resolution (1.25 mm) chest CT. HRCT is performed using a conventional CT scanner. However, imaging parameters are chosen so as to maximize spatial resolution: [1] a narrow slice width is used (usually 1–2 mm), a high spatial resolution image reconstruction algorithm is used, field of view is minimized, so as to minimize the size of each pixel, and other scan factors (e.g. focal ...
The Systematized Nomenclature of Medicine (SNOMED) is a systematic, computer-processable collection of medical terms, in human and veterinary medicine, to provide codes, terms, synonyms and definitions which cover anatomy, diseases, findings, procedures, microorganisms, substances, etc. It allows a consistent way to index, store, retrieve, and ...
The patient may be advised to wear a neck brace or collar (for up to 8 weeks) that serves to ensure proper spinal alignment. Wearing the brace heightens one's awareness of posture and positioning and helps prevent movements (e.g., sudden and/or excessive bending or twisting of the neck) that may aggravate or slow down the healing process.
In conventional CT machines, an X-ray tube and detector are physically rotated behind a circular shroud (see the image above right). An alternative, short lived design, known as electron beam tomography (EBT), used electromagnetic deflection of an electron beam within a very large conical X-ray tube and a stationary array of detectors to achieve very high temporal resolution, for imaging of ...
CT angiography is a contrast CT taken at the location and corresponding phase of the blood vessels of interest, in order to detect vascular diseases. For example, an abdominal aortic angiography is taken in the arterial phase in the abdominal level, and is useful to detect for example aortic dissection .
