Computed tomography (CT) is a medical imaging method employing tomography created by computer processing. Digital geometry processing is used to generate a three-dimensional image of the inside of an object from a large series of two-dimensional X-ray images taken around a single axis of rotation. CT produces a volume of data which can be manipulated, through a process known as "windowing", in order to demonstrate various bodily structures based on their ability to block the X-ray/Röntgen beam. Although historically the images generated were in the axial or transverse plane, orthogonal to the long axis of the body, modern scanners allow this volume of data to be reformatted in various planes or even as volumetric (3D) representations of structures. Although most common in medicine, CT is also used in other fields, such as nondestructive materials testing. Another example is the DigiMorph project at the University of Texas at Austin which uses a CT scanner to study biological and paleontological specimens. Usage of CT had increased dramatically over the last number of years with an estimated 72 million scans performed in 2007. From Wikipedia under the

Q. Sounds crazy but I have sinus headaches along with a big bump on the top of my head. Whenever my sinus hurt that bump hurts also, pressure I guess. Will the CT scan determine something wrong with my brain? Asked by John Justin Garcia - Sat May 10 12:46:03 2008 - - 1 Answers - 0 Comments A. If they look for it it will. Tell the Dr about the lump and ask him/her to check it out as well. Answered by Kim B - Sat May 10 13:01:50 2008 What could a mass found on a lung during a ct-scan be? Q. My sister recently had e-coli poisoning and went in for a ct-scan to make sure there was no damage to her intestines. They found a black mass on her lung and nodules on her liver. What could this be? Cancer? A cyst? Asked by Rue - Thu Jul 30 18:28:13 2009 - - 2 Answers - 0 Comments A. I know it can be extremely scary. I would like to share with you three similar instances: a)A year ago I had a cat scan and afterwards two pet scans. Everyone who I knew told me that it was definitely Lymphoma, and Thank GD it was not. b)I have a relative who had something strange appear on a lung scan. It ended up being sometihng called a lymph hemangioma a kind of benign growth. c)I had a neighbor who scans showed something on the lung. The radiologist was sure that it was some kind of lung tumor. When he went for a second opinion, the Dr found it to be sarcoidosis. My only two cents is - get someone very knowledgeable in this area. Answered by Shaul - Fri Jul 31 04:13:15 2009 How much does an individual CT scan cost the NHS? Something to think about?
Q. Hi, I was wondering if anyone has ever taken the time to find out how much an individual CT scan costs the NHS? Things like how much electricity is used during that 10 minute scan (for example), the staff needed for that patient (radiographers, radiologists, nurses etc.) and if you're really clever, working out how much in typical salaries would have been spent for scanning this individual patient. The examination that I'm thinking of is the brain following trauma. I know any calculations would be theoretical but if someone is willing to take the time to work a few things out they will get 10 wonderful points plus an additional two for just posting! I want to know how much the NHS are spending on CT brain scans per patient... Thanks… [cont.] Asked by Jesus Saves - Thu Oct 4 08:45:02 2007 - - 5 Answers - 0 Comments A. All these things have in fact been calculated quite carefully, not just head scans, but just about any procedure (certainly within Radiology) that you could think of. There are several reasons for this. 1. So the department knows how much to charge the fundholders (e.g. Primary Care Trusts) or private sector if appropriate. 2. So the managers know how much the department costs to run when they want to start/stop services. 3. To get an idea of how useful a procedure is in terms of the cost per information etc. 4. With the advent of 'fee for service' departments, 'Choose and Book', 'Commission of Health Improvement' etc, costs have to be known for purposes of the internal market. In any event, it probably costs about 200 to do a head scan,… [cont.] Answered by Jon - Thu Oct 4 10:35:07 2007 From Yahoo Answer Search: "CT scan" |
