Well be able to understand a few basic physical principles about how ultrasound interact with various human tissue as well as having a working knowledge about the key buttons used to control the ultrasound machine will maximize your ability to acquire quality images.
In a timely fashion the 2d or bmode stands for brightness mode and this is simply white dots on a black background and this is the reset button on most auto sound devices that dad takes up any other the are changes may have made or instrumentation calibers things like that the brightness mode reset it back to its native state.
The next but you may encounter is the emerald the mmode stands for motion mode and departed despite the corresponds the top with a tissue corresponds to this graphical representation right here %uh motion this is a two dimensional tracing up anything moving on the screen.
So structures down here like this is the plural line right here because that sliding back and forth we see it represented as sandy appearance down here at the bottom of the screen so motion appears granular whereas structures that are static over time appear as horizontal lines when using motion mode.
And then there’s the color flow doppler color flow Doppler is directional flow red is flow towards the transducer blue is flow away from the transducer as we can see here in this city or take aneurysm there is a turbulent flow kinda going back and forth.
And a nother typeof doppler is called power flow Doppler or color power Doppler the way you activate daddy’s after depressing that color biting you then activate this by the soft key that corresponds to the power flow power Doppler a function and this is a orange only type of flow it’s not.
Directional it’s a very a sensitive type of flow and arm is used for on identifying perfusion in tissue that has a low perfusion states such as the testicles then there’s post wave Doppler sometimes called spectral Doppler after depressing the Doppler a button you get this sampling gate here and you can on.
Direct where you would like that sampling in this case it’s over the supply Abyan artery and we have therefore arterial waveform and these are called velocity waveforms missus up the the the the pickup this spike corresponds to 20 centimeters per second whereas over here these are being this way forms this is.
SelfTest for Thyroid Problems
Hi i’m allen peters, physician healthy aging expert from nourishingwellness and I’m here today for About to share with you how to do a SelfTest for Thyroid Problems. This is a very simple exam which I do on every patient that I see, and you can do on yourself. You put your head back and feel for the thyroid cartilage. You feel both sides of the cartilage, and you might feel a small amount of soft tissue. You can exaggerate the tissue or exaggerate the thyroid cartilage by swallowing several times. If you feel more than a small amount.
Of tissueif you feel a swelling or lumps or bumps this may be indicative on an enlarged thyroid or thyroid nodules which could be benign or malignant. If you do feel something large you should see your . If he or she agrees the next step is usually getting an ultrasound. Now I want to mention that there are also some lumps behind the cartilage on the side of the neck, and these are just lymph nodes. Im talking about the actual thyroid cartilage itself and the gland that is right there in.
That particular area. by the way, i want to emphasize that you could have an abnormal thyroid without being able to feel anything. It can be either hypothyroid or hyperthyroid. So if you are having symptoms of an increased metabolic rate like high blood pressure and palpitations and anxiety and nervousness to a great degree. Or if you are having slow down symptoms of slowdown metabolism like being tired and fatigued and depressed and low blood pressure and low pulse rate and constipated and hair falling out, then you.
