CT - Computed tomography

Computed tomography bases on X-ray technology. However, during CT examination X-ray pictures are taken from different directions. Thanks to multislice spiral CT technology, an X-ray tube and detectors rotate around the person and record up to 64 layers at the same time at high speed. High-performance computers create anatomical images from these data sets. The CT of Beta Klinik adapts the radiation dose automatically in real time during a CT examination. This makes the best radiation dose for every individual patient possible.

In some cases, it can be necessary to use a contrast agent in order to make specific characteristics of a certain tissue visible that would not be visible without it. Depending on the region to be examined, this contrast agent has to be taken orally, intravenously or intra-thecally (in the dural sack/spinal canal, e.g. in case of conventional myelography or CT myelography). If you have to take it orally, for example, you drink a certain amount of contrast agent before the examination. Because CT contrast agents contain iodine, the intravenous application can cause an (pseudo-)allergic reaction. Therefore it is important to answer a few questions before the examination, also to figure out if you are allergic to iodine.

There are some contraindications for CT usage, that are reasons against undergoing a CT examination. These contraindications do not generally exclude CT usage. But an experienced physician has to decide if the CT examination can be performed. The following contraindications are known:

• iodine allergy (relevant in case of intravenous application)
• reduced kidney function (kidney insufficiency)
• thyroid hyperfunction
• pregnancy
