Why is a transesophageal echocardiogram performed?
A transesophageal echocardiogram (TEE) is a special type of echocardiogram. It is usually done when your doctor wants to look more closely at your heart to see if it could be producing blood clots. Like an echocardiogram, the TEE uses high-frequency sound waves (ultrasound) to examine the structures of the heart.
Why do I need a transthoracic echocardiogram?
Getting a transthoracic echocardiogram, or TTE, gives your doctor a good view of your overall heart health including seeing how your heart beats and checking for any heart issues.
What are the risks of an echocardiogram?
Are there any risks or side effects? A standard echocardiogram is a simple, painless, safe procedure. There are no side effects from the scan, although the lubricating gel may feel cold and you may experience some minor discomfort when the electrodes are removed from your skin at the end of the test.
What can a transesophageal detect?
Transesophageal echocardiography (TEE) is an ultrasound technology that provides highly detailed images of the heart and its internal structures. Our heart experts use TEE to detect blood clots, evaluate heart valves, and guide treatment for arrhythmias (abnormal heartbeats) and many other heart conditions.
What sedation is used for transesophageal echocardiogram?
Use of deep intravenous sedation with propofol and the laryngeal mask airway during transesophageal echocardiography.
Do you need to fast for a transthoracic echocardiogram?
No special preparations are necessary for a standard transthoracic echocardiogram. You can eat, drink and take medications as you normally would. If you’re having a transesophageal echocardiogram, your doctor will ask you not to eat for several hours beforehand.
Are you awake during a TEE?
Once the test is ready to begin, you will be given a sedative to help you relax, and a numbing medication will be sprayed down your throat. This will make the passage of the transesophageal ultrasound probe more comfortable. You will be awake enough to swallow if necessary.
How long does it take to recover from TEE?
You should feel back to normal by the next day. PAIN/DISCOMFORT: You may have a sore throat or a hoarse voice for 48 hours after the test. » It may be helpful to use lozenges or take regular strength Tylenol® (acetaminophen) to relieve the symptoms.
Are you awake during TEE?
Are you put to sleep for a TEE procedure?
They’ll place an intravenous (IV) catheter into one of your veins, usually in your hand or arm. The IV will be used to give you anesthesia (medication to make you sleep) during your procedure. You may also get fluids through the IV before your procedure.
What does red mean on an echocardiogram?
Traditionally, flow towards the transducer is red, flow away from the transducer is blue, and higher velocities are shown in lighter shades. To aid observation of turbulent flow there is a threshold velocity, above which the color changes (in some systems to green).
How uncomfortable is a TEE?
You shouldn’t feel any pain. But you may feel a bit of pressure in your chest as your provider moves the transducer into different positions. This part will take about 10 to 15 minutes. Your provider will remove the tube from your throat.
What is ultrasound super-resolution?
Introduced 10 years ago, ultrasound super-resolution can improve the resolving power of ultrasound imaging by a factor of 10 with respect to the diffraction limit (wavelength/2). This review describes ultrasound super-resolution as it is conceived by several groups which introduced several of the precursor work on the field.
What is the maximum frequency required for super resolution ultrasound imaging?
For instance, ultrasound super-resolution imaging at great depth (>10 cm) or through the skull would require 1–3 MHz transducers, few centimeters depth would be achieved around 4–12 MHz, while small animal imaging would be performed at frequencies beyond 15MHz.
Is there a super-resolution ultrasound method for brain vascular mapping?

What is 3D ultrasound localization microscopy used for?
3-D ultrasound localization microscopy for identifying microvascular morphology features of tumor angiogenesis at a resolution beyond the diffraction limit of conventional ultrasound. Theranostics2017a;7:196.
