Colorectal Carcinoma: Local Tumor Staging and Assessment of Lymph Node Metastasis by High-Resolution MR Imaging in Surgical Specimens
Figure 5
The size, signal intensity, and border contour of lymph nodes in colorectal carcinomas on high-resolution MR images. (a) Box plot shows the diameter (measured in millimeters) of benign and metastatic lymph nodes on high-resolution MR images. The horizontal line within the box is the median value (50th percentile), the boundaries of the box represent 25th and 75th percentiles, and whiskers show 10th and 90th percentiles. Values above the 90th and below the 10th percentiles are plotted as data points (circles). (b) Bar chart shows the number of benign (white bars) and metastatic (black bars) lymph nodes on high-resolution MR images, according to signal intensity on T2-weighted MR images. (c) Bar chart shows the number of benign (white bars) and metastatic (black bars) lymph nodes on high-resolution MR images, according to border contour.
