WebGradient echo is a magnetic resonance imaging (MRI) sequence that has wide variety of applications, from magnetic resonance angiography to perfusion MRI and diffusion MRI.Rapid imaging acquisition allows it to be applied to 2D and 3D MRI imaging. Gradient echo uses magnetic gradients to generate a signal, instead of using 180 degrees … TEE (echo) URL of Article A standard transesophageal echocardiography ( TOE , or TEE in US English) is a type of echocardiography using an endoscopic transducer, which is advanced into the thoracic esophagus, offering generally superior visualization of the great vessels and posterior cardiac structures … See more Transducer manipulation is more complex than with a transthoracic probe, and the following terminology defines the adjustments one may make to obtain long, short, and 4-chamber axis images of the heart 4: 1. movement … See more Typically performed in an intubated, sedated patient (although examination with the use of topical anesthesia and low-dose analgesia is … See more Indications for transesophageal echocardiography include the evaluation of cardiac and aortic structure and function in situations such as 2: 1. transthoracic echocardiography is … See more

Gradient echo - Wikipedia

WebThe Ernst angle concept has already been introduced in a previous Q&A to which the reader is referred for more details. It should be noted that although the Ernst angle gives the highest signal for a given tissue for a certain TR/T1 combination, it does not necessarily maximize image contrast between two different tissues.
