Computer Tomography

Computer tomography is an imaging modality with which an x-ray beam is rotated around the patient yielding cross-section images (tomograms) of the examined region. A high performance computer enables the reconstruction of images in any given projection and the visualization of organs in 3-D technique. Thus, the radiologist possesses a powerful and rapid tool for precise diagnoses. Classic areas of application are diseases of the brain, lungs, internal organs and vertebral discs.

At our practice we operate so-called volume scanners of the newest generation. The scanners are equipped with a special low dose technology (ASiR = Adaptive Statistical iterative Reconstruction), allowing a dose reduction of up to 80% for cardiac imaging and up to 40% compared to conventional systems.

The high rotation speed of the x-ray emitter and the simultaneous motion of the table through the opening of the scanner (spiral technique) allow a full examination of the entire body in only a few seconds and with a resolution of 0,6 mm slice thickness. Especially in the field of emergency medicine, this saves valuable time.

The radiological practice Calw-Leonberg operates CT scanners of the latest generation, so called volume scanners. Thus, making a powerful imaging modality available to our patients without the risk of excessive radiation exposure. Classic areas of application are diseases of the brain, lungs, internal organs and the vertebral column.

The modern CT scanners enable a virtual view of the internal structure of the body. In many cases an intravenous administration of contrast agent is required for the examination. 3-D visualization of the bronchial system, the coronary arteries, the cardiac valves, the digestive tract and of the arterial system can be realized and are performed routinely. In many cases invasive procedures such as Endoscopy and Cardiac catheterization can thus be avoided.

A further application of computer tomography is CT guided pain therapy. With the help of a three-dimensional laser system a thin injection needle is inserted under local anesthesia. The exact location of the needle is verified by low dose CT images. Using this method, anti-inflammatory drugs and local anesthetics can be injected with high precision in the area of the intervertebral joints, the sacroiliac joints or in the area of the nerve root.
