Radiation And Echocardiograms
Echo refers to reflections of sound waves, typically 0.5-10mhz, sent through a body structure, all variants of water density. Cardio refers to heart. Gram refers to a picture or graphical representation of the data. A form of us, these help see certain aspects of our hearts behavior/function, real-time in motion picture video. Quality & usefulness varies widely as ...Read more
Is an echocardiogram with contrast safe? How long does that test take in general?Lastly, is the IV they use as big as the one used during surgeries?
During a routine echocardiogram, when they measure the rv diameter, do they also check for rv hypertrophy?
During routine echocardiogram, is the ejection fraction usually calculated using the m-mode estimate, or the 2d volume (tracing the lv) measurement?
Either: Both methods are used. However, it is generally accepted that tracing the endocardial borders of the left ventricle at end systole and end diastole in two separate planes gives the best estimate of ejection fraction. When using only the m-mode tracing, there are many assumptions built into the estimate of ejection fraction that can challenge accuracy. ...Read more
Doppler: That is the doppler part of the echocardiogram. The sound represents the flow of blood. You could get an idea of what the pictures look like by listening to that sound. How loud the sound is and whether it occurs during systole or diastole would give you a clue for istance, but most people interpreting the study just look at the images and don't pay much attention to those sounds. ...Read moreSee 1 more doctor answer
Can hypertrophic cardiomyopathy be missed during an echocardiogram? (A regular echo, done while lying down.)
During my echocardiogram the nurse also scanned over my abdomen (pulse present). Will the doc be able to confirm there is or isn't an Ab. aneurysm?
This is light of extremely short wavelengths typically produced either among the stars / in cosmic rays or by radioactive element decay. Gamma rays form the background of normal radiation in which we all live; it is substantially greater than the exposure we get from imaging scans or should get from ...Read more
Cardiac echo is a somewhat redundant term for "echocardiogram." during this painless procedure, harmless sound waves are passed into the chest and reflected back, providing a detailed image of the heart, measures of the flow of blood within it, and information about certain structures which surround ...Read more
