The diagnostic abilities of MRI and US for ankle ligamentous injuries (anterior inferior tibiofibular ligament (AITFL), anterior talofibular ligament (ATFL), calcaneofibular ligament (CFL), medial deltoid ligament (MDL)) were compared by Wilcoxon signed-rank test.

After chemotherapy (FOLFIRINOX or nab-paclitaxel-gemcitabine), the treatment group was exposed to FUS (frequency 0.35 MHz, mechanical index 0.5, pulse length 2.9 ms (1000 cycles), pressure amplitude 0.3 MPa and MBs (SonoVue) for 35 min).

Therefore, computer-aided cancer diagnosis in ABUS volume is highly expected to help the physician for breast cancer screening.

The method automatically segments the anatomical structures subsequent to the anchor frame and classifies the US video as normal or abnormal. The method consists of two phases. The first phase combines three residual networks (ResNets) extended with a self-attention block and a refinement module. The second phase extends a ResNet with two CoordConv layers integrating spatial coordinates. We assess segmentation performance using the intersection over union (IoU) and dice similarity coefficient (DSC) metrics and classification of US videos using sensitivity and specificity. We also investigate the tolerance to failure of the method by introducing mislabelled anchor frames.
