Anterior talofibular ligament (ATFL) injury is a commonly seen sports-related injury and a major underlying pathology of chronic ankle instability. However, it is difficult to accurately identify chronic injury of the ATFL. ⋯ US examination is a reliable and accurate method to evaluate chronic ATFL injury.

Technological advances introduced hand-carried ultrasound (HCU) imagers in daily clinical workflow providing several benefits such as fast bedside availability and prompt diagnosis. ⋯ HCU provides rapid, practical, reliable, and cost-effective diagnosis of PE in patients on cardiothoracic ICU.

Surgical treatment is the only option for long-term survival in patients with colorectal liver metastasis (CRLM). Contrast-enhanced CT and MRI are usually used for preoperative liver imaging. The initial surgical strategy for liver resection is based upon these findings. Further optimization of the surgical strategy by contrast-enhanced intraoperative ultrasound (CE-IOUS) might further improve the surgical outcome. ⋯ CE-IOUS is essential to ensure optimal and complete tumor resection both in patient with solitary CRLM and multiple metastases.

Comparison of the diagnostic value of FDG-PET/CT and axillary ultrasound for the detection of lymph node metastases in breast cancer patients.
FDG-PET/CT is increasingly being used for breast cancer staging. Its diagnostic accuracy in comparison to ultrasound as the standard non-invasive imaging modality for the evaluation of axillary lymph nodes has yet not been evaluated. ⋯ Though more accurate compared to ultrasound for evaluating the axillary lymph node status FDG-PET/CT is only as sensitive as ultrasound when it comes to the detection of axillary lymph node metastases. Due to the low sensitivity FDG-PET/CT cannot act as a substitute for Sentinel lymph node biopsy. FDG-PET/CT is able to detect previously unknown locoregional extra-axillary lymph node metastases.

Quantification of intervertebral disc degeneration based on intensity of the nucleus pulposus in magnetic resonance imaging (MRI) often uses the mean intensity of the region of interest (ROI) within the nucleus pulposus. However, the location and size of ROI have varied in different reports, and none of the reported methods can be considered fully objective. ⋯ The present method offers adequate discrimination and could be useful for longitudinal tracking of intervertebral disc degeneration with sufficient reproducibility.
