Fig. 2: Apparent-diffusion coefficient (ADC) analysis.
From: Effects of effective stereotactic radiosurgery for brain metastases on the adjacent brain parenchyma
a Contrast-enhanced T1-weighted image (left) and corresponding ADC map (right) obtained in a patient with a metastasis from renal cell carcinoma (arrows) within the right temporal lobe 17 weeks after stereotactic radiosurgery (SRS). b Region of interest placement in the contrast-enhancing lesion (left) and in the parenchyma adjacent to the target borders of SRS (right). c Scatter plot with fitted regression function for ADC in the parenchyma adjacent to the target borders of SRS. Solid circles: normalised values for each lesion. Solid bold lines: fitted regression line; darkened areas: 95% confidence interval. Note: continuously elevated ADC values throughout the observation period.
