Web24 de mai. de 2024 · Structure of the CNN. To reduce the contrast-enhanced areas from a CT image and produce a non-contrast CT image, we use the approach of Zhang et al. [] that involves using a convolutional neural network for image denoising.It was assumed that we regarded the contrast-enhanced region as the object to be processed. Contrast CT, or contrast enhanced computed tomography (CECT), is X-ray computed tomography (CT) using radiocontrast. Radiocontrasts for X-ray CT are generally iodine-based types. This is useful to highlight structures such as blood vessels that otherwise would be difficult to delineate from their surroundings. Using contrast material can also help to obtain functional information about tis…
