Elastography

High diagnostic reliability due to high-resolution color Doppler sonography

In addition to the PSA test and the palpation examination, effective early detection always includes a special ultrasound examination through the rectum, the transrectal ultrasound (TRUS). For this purpose, the urologists of the West German Prostate Center use a high-resolution colour Doppler ultrasound device of the latest generation. The so-called color Doppler dupplex sonography combines ultrasound images of the tissue with a colored representation of the blood flow in the vessels. This allows not only anatomical but also physiological changes in the prostate tissue to be made visible. The advantage: tumor-suspected areas can be diagnosed with a higher accuracy than with conventional ultrasound devices.

The three-dimensional representation of the prostate in 3-D (3-D imaging) also enables the examining physician to obtain a precise picture of the localization of the tumor or tumor centres in the prostate, in order to precisely plan a tissue removal (biopsy) to ensure the diagnosis.

Even more precise: Ultrasonic-supported real-time elastography

In order to achieve an even more precise diagnosis, the West German Prostate Center uses so-called elastography in addition to color Doppler ultrasound. The examination is short and painless and takes place through the rectum, as with transrectal ultrasound. The doctor applies light pressure to the prostate with the ultrasound probe. Due to the different stretching properties of tumor and normal tissue, minimal time shifts of the echo signals occur. With the help of special software, these are displayed in color on the monitor in real time and conspicuous areas are marked in the ultrasound image. The state-of-the-art procedure is particularly suitable for patients with a high PSA value but at the same time negative results after biopsy.

With ultrasound assisted elastography, the West German Prostate Center is one of the few centers in Germany to offer this innovative imaging technique for differentiated tumor diagnostics, thus rounding off its spectrum of diagnostic methods.
