What is a hellic CT scan?
Computer tomography (CT) Scanning is a imaging technique that shows virtually everything inside the body, including bones, soft tissues and blood vessels with a single scan. Figures from conventional scanning are two -dimensional cuts and are produced by a combination of X -rays taken from a number of different angles. Helical CT scan, also called Spiral CT scanning, uses a special scanning technique that produces better images in a much less time than conventional computer tomographic scanning. The scanner rotates around the patient in the spiral and creates images that are three -dimensional and usually show in more detail than conventional CTS.
Helical CT scan comprises the patient scan without stopping when it moves with a scanner. This method results in sharper images of soft tissues and blood vessels and are useful in the rapid diagnosis of injury to patients who had serious trauma, especially in the chest. The source of internal damage can often be bull on the potter on HeliCaling CT scan, which provided doctors more time to intervene than blood loss becomes critical.
In many cases, the patient is given a contrasting material for the production of blood vessels and certain organs excel more clearly. What is used and how it is served usually depends on what is examined. Contrast injections define blood vessels and certain organs such as gall bladder, while the contrast may be given orally to patients with problems in the stomach or esophagus. In some cases, the enema is used to highlight the intestines, so the structure is easier to see. The contrast material often causes certain discomfort, such as diarrhea or flatulence, but in most cases side effects do not last long.
It is not unusual to use some type of contrast material in performing healic scanning CT, which increases the clarity of the images. Such procedure is not always used and may be a sliceCells, unless it is medically necessary or in certain emergency situations, but are often necessary for clarity. For example, scanning of pulmonary embolism is a good use of Helical CT scanning, but for the best results usually requires the use of contrasting material.
Use of Helical CT scanning requires only about 30 seconds; This is the key reason why images tend to be so clear when comparing conventional CT scanning, which can take several minutes. Longer scanning may have errors when images are sorted, due to breathing or other patient movement, sometimes cause unclear or defective results. Because the patient can usually hold breath for a short time required by spiral scanning, the results are much more reliable.
