Final answer:
Increasing the Echo Time (TE) in MRI imaging results in more pronounced T2 weighting, improving the contrast in an image by allowing differentiation between tissues based on their T2 relaxation properties.
Step-by-step explanation:
In medical imaging, particularly in Magnetic Resonance Imaging (MRI), the Echo Time (TE) is crucial for determining the T2 weighting of an image. The TE is the time between the delivery of the RF pulse and the peak of the echo signal. Increasing the TE leads to increased T2 weighting because it allows for more transverse relaxation to occur. Tissues with longer T2 relaxation times will still have significant signal at longer echo times, while those with shorter T2 times will have their signals decay more rapidly. This is essential for enhancing contrast in MRI images and making it possible to differentiate between tissues with different T2 relaxation properties, such as identifying areas of inflammation.
