(a) Radiomics nomogram. The radiomics nomogram, combining Fat Fraction, plaque burden, plaque ulceration, and Rad-score, was constructed in the training set. (b–e) For each below figure, a patient with symptomatic carotid plaque was selected as an example to illustrate the function of the radiomics nomogram. (b) Magnetic resonance diffusion-weighted imaging demonstrates a left-sided ischemic stroke in this patient. (c) Sagittal CTA reconstruction shows an internal carotid artery plaque (long arrow) and plaque ulceration (short arrow). (d) Axial CTA shows an internal carotid artery plaque near the internal carotid artery lumen with plaque ulceration (long arrow). (e) Using the “Liver VNC” program, measure the Fat Fraction of the plaque. Table showing predicted probability for this patient using radiomics nomogram.
