Cardiac ct with contrast vs. Echocardiogram

I'm not sure if I'm in the right place to ask this question, but I'm just gonna go for it 😊 any and all information is greatly appreciated.  What is the diffrence between a cardiac ct with contrast and a echocardiogram? Is one superior over the other? Are they both able to find the same things? I do know the ct exposes you to radiation, but other than that is there really a difference?

    According to my little knowledge the two tests are entirely different. In cardiac CT a die in injected intravenously in the blood stream and then imaging of heart is done by strong  X-rays. By this scan flow of die is pictured to see if the flow of blood in different parts of the heart is fine or there is some blockage in any vessel. This test is an alternative of Angiography. In Echo sound waves are used to scan the heart to see the size and function of heart chambers and valves as well as pumping of heart is checked which is measured as ejection ratio.

    I just had a calcium cardiac ct scan to see if there was placque build up. Put on the silly gown, have a couple of electrodes attached then lay down on table. Machine is about a foot thick and passes over the chest. Takes about five minutes. 

    Echo is also painless but is for analyzing heart function. Takes about 20 minutes.
