WebFigure 2. Density plot comparing the proportion of patients with low (<5 ng/L) and intermediate (≥5 ng/L–99th centile) cardiac troponin concentrations for each plaque burden subtype. Proportionally, low-attenuation plaque burden appears lowest in patients with a high-sensitivity troponin of <5 ng/L compared with other plaque subtypes. WebMar 21, 2024 · At CT and MR imaging, findings in acute viral hepatitis are nonspecific and include hepatomegaly and periportal edema. At CT, heterogeneous enhancement and well-defined regions of low attenuation may be present. At MR imaging, periportal edema appears as high-signal-intensity areas on T2-weighted images. WebJan 3, 2024 · At CT, enhancement requires an increase of attenuation of at least 15–20 HU from unenhanced to the contrast enhanced images . A 10–15 HU change in attenuation can be due to incorrect placement of the region of interest, patient motion, or beam hardening from adjacent enhancing renal parenchyma (the so called … ttc viability test
