Center for Radiology and Imaging of the St. Catherine Specialty Hospital uses state-of-the-art technology in performing radiological diagnostic tests. Ultrasound examination is painless, non-invasive and does not use ionizing radiation. An ultrasound examination is a procedure for creating a two-dimensional (and three-dimensional) cross-sectional image of the inside of the human body. During the examination, probes (transducers) of certain frequencies are most often used, which are positioned directly on the patient's skin. Ultrasound has proven to be an excellent tool for diagnosing various conditions in internal organs, for example: liver, heart, ovaries, kidneys, thyroid, testicles, etc.
