What is a hydro-CT abdomen? A hydro-CT describes a special type of examination in which water is used as a contrast medium. The stomach and intestines in particular can be assessed well with a Hydro-CT. To do this, the patient must drink approx. 500ml of water shortly before the examination begins. Often an antispasmodic drug … What is a hydro-CT abdomen? | CT abdomen
Definition A frequently used imaging method for the representation of the lungs is computed tomography (CT). This is a special X-ray examination in which several body cross-sections are recorded and combined into a three-dimensional image with very high resolution. The imaging is performed with the help of X-rays, which are absorbed to varying degrees by … CT of the lungs
Preparation of the CT thorax Before performing a CT thorax to visualize the lungs, there is always a consultation with a doctor. This preliminary talk serves to explain the benefits and risks of the examination. The patient should be informed about the radiation exposure during imaging. If a contrast medium is planned to be administered, … Preparation of the CT thorax | CT of the lungs
Duration of the CT examination The CT examination is a simple and fast imaging diagnostic procedure. For this reason it is often preferred to the MRT examination. Especially in emergency situations, the significantly faster performance of a computer tomography is indicated. Depending on the issue at hand, a CT thorax to examine the lungs takes … Duration of the CT examination | CT of the lungs
What is a CT abdomen? CT is the term used to describe what is known as computed tomography. This is a procedure that works with X-rays just like the classical X-ray examination. However, not only one image is taken, but a series of images is taken while the computed tomography scanner rotates around the patient. … CT abdomen
The evaluation of the CT abdomen The CT images are evaluated by a radiologist who has been informed of the reason for the examination by the attending physician (e.g. abdominal pain of unclear origin). The radiologist then assesses the images with regard to the patient’s symptoms. Often a possible cause can be found quickly, e.g. … The evaluation of the CT abdomen | CT abdomen
The duration of the investigation In contrast to the MRT examination, a CT examination is quite fast. The examination itself usually only takes a few minutes. However, it should be noted that contrast medium is required for many examinations. Particularly in the abdominal area, the contrast medium must be drunk frequently and then, depending on … The duration of the investigation | CT abdomen
During computed tomography, the radiation causes a high radiation exposure. Compared to X-rays, this radiation exposure is particularly high and therefore more dangerous than an X-ray examination. Nevertheless, computed tomography (CT for short) offers many advantages over X-rays. On the one hand, cross-sectional images of the body can be taken, and on the other hand, … Radiation exposure of computer tomography
Desire to have children An image taken by means of computer tomography always leads to a high radiation exposure. For this reason, computer tomography should only be carried out during pregnancy in an absolute emergency, as it is still not known today what the effects on the unborn child would be. An exception is computed … Desire to have children | Radiation exposure of computer tomography
Cardio-computed tomography (synonyms: cardio-CT; CT-cardio, cardiac computed tomography (CT); coronary CT (CCTA)) refers to a radiological examination procedure in which computed tomography (CT) is used to image the heart and its supplying vessels. Cardio-CT can be divided into different examination modalities. One is calcium scoring (calcium scoring; determination of the extent of calcified plaques in … Cardio Computer Tomography
Definition With the help of a CT, ionizing radiation is used to obtain high-resolution images of the body. A low-dose CT uses a particularly low radiation dose compared to a normal CT. This reduces the radiation dose to the patient, which is associated with risks. Low-dose CT is used, among other things, to detect stones … Low-dose CT
Evaluation The CT image is evaluated by a radiologist. The results are given to the treating physician. CT images, including those of a low-dose CT, have a significantly better resolution than normal X-rays. Therefore, much more can be recognized and diagnosed on them. However, even here the images are not always 100% clear. For example, … Evaluation | Low-dose CT
