Ultrasound uses sound waves, not x-rays, to generate images. A jelly-like substance is applied to the skin overlying your liver. Then a probe, called a transducer, is passed over the skin. The transducer sends out sound waves that pass through the body and are echoed back. The transducer receives the echoes and transmits them to a computer console which in turn interprets the echo data as internal organs and tissues.
Well, first of all, I had to wait over an hour for my name to be called. But I waited patiently because I know that people are busy and everyone has things to do and people to see. So I finally get back to the little room and the guy tells me to disrobe from the waist up and put on the gown. That's fine, although it was a tad chilly. I comply as I am a good patient. Then I have to roll over on my left side and he squirts the jelly on my side. I must say that it was very warm. I wasn't expecting it to be quite that warm. I would even go so far as to say that it was a tad too warm! But better than too cold. OH...shivers! Just thinking of it! Anyway, then I had to breath in and hold my breath....breath out. Repeat several times. Piece of cake. Turn over on my right side and do the same thing. Then the weirdest thing happened. The guy stopped telling me when to breath in and out and hold my breath. Well, I can't hold my breath forever, so I started breathing again. Then I took a breath and held it on my own. I did that several times thinking I was doing the right thing. All the while he was saying nothing – just moving the probe all over my side (which hurt by the way!).
Then all of a sudden he stops and in a slightly irritated voice says that I need to hold my breath and stop breathing. Well I was just flustered! What the hell had I BEEN doing sir? Without your guidance I might add! So what do I do? I apologize! “I'm sorry, I'm not very good at holding my breath.” So then he starts coaching me again. And all is well. What happened there? I don't know. I just know that he said the pictures turned out clear and I did fine. I'm glad that's over. My hepatologist will have my results for me shortly,, and my ribs will feel better soon. All in all, it wasn't a bad experience. So pray for me that my results will be negative to the liver cancer. I sure don't want any of that. I have enough on my plate already!!!!!!!
Here's a sample of what liver cancer can look like from an ultrasound.
This is not my ultrasound or liver:
