Nada contra a Ressonância...
High-spatial-resolution magnetic resonance image, with cross-sectional coregistered images through plaque in the internal carotid artery. Baseline T2-weighted image (A) and precontrast (B) and postcontrast (C) T1-weighted images and plaque contours (D) (white: carotid artery lumen; light gray: vessel wall area) are shown. T2-weighted image (A) shows isointense plaque, precontrast T1-weighted image (B) shows hyperintense plaque, and postcontrast T1-weighted image (C) shows no enhancement of the plaque, which matches the criteria of a lipid-rich necrotic core with no or little hemorrhage. Follow-up T2-weighted (E) and precontrast (F) and postcontrast (G) T1-weighted images and plaque contours (F) (white: carotid artery lumen; light gray: vessel wall area; dark gray: hemorrhage) are shown. T2-weighted image (E) shows a striking hyperintense area within the plaque, adjacent to the lumen (dark gray area in H). This area is hyperintense at the precontrast T1-weighted image (F) and does not enhance at the postcontrast T1-weighted image (G). These findings indicate recent intraplaque hemorrhage.
Belíssima imagem de placa na carótida com progressão do ateroma por hemorragia intra-placa.
O fenômeno de hemorragia intra-placa e progressão da estenose é muito comum também na coronária.
Mas carótida é carótida e coronária é coronária! rsrs
