The physicians at Northwest Clinic offer ultrasound methods to examine your body non-invasively. With Abdominal ultrasound, your inner organs such as your liver, gallbladder, pancreas and kidneys can be checked. Both gastroenterologists are very experienced with ultrasounds of the stomach and bowel including the appendix. All kinds of abdominal pain (acute and chronic), diarrheas or constipation can be evaluated by this method. With Doppler Ultrasound of the vessels your doctor is able to check for deep vein thrombosis in the legs or arms. For measurement of the flow in the carotid arteries (supply the brain with blood) Doppler ultrasound is the gold standard and the risk for strokes can be evaluated and treatment initiated. Thyroid ultrasound evaluates goiter, inflammation and nodules of this important gland. The so called Intima media thickness measurement is an easy method to calculate the risk for arteriosclerosis in all arteries of the body.
The 3 main types are: external ultrasound scan – the probe is moved over the skin. internal ultrasound scan – the probe is inserted into the body. endoscopic ultrasound scan – the probe is attached to a long, thin, flexible tube (an endoscope) and passed further into the body.

What is the principle of ultrasound?
The reflected waves are captured by the probe and the piezoelectric crystals convert the sound energy back into electrical energy. The processor transforms this energy into an ultrasound image. The conversion of electrical to sound energy and back is the piezoelectric phenomenon.
