Comparative Study
Comparison of sonography with sonographically guided fine-needle aspiration biopsy and core-needle biopsy for initial axillary staging of breast cancer.
The purpose of this study was to determine the roles of sonography and sonographically guided fine-needle aspiration biopsy and core-needle biopsy for initial axillary staging of breast cancer. ⋯ Both sonographically guided fine-needle aspiration biopsy and core-needle biopsy were useful for axillary staging of breast cancer with high sensitivity. However, fine-needle aspiration biopsy is recommended based on the advantages of low cost and minimal invasiveness.

With the proliferation of portable sonography and the increase in nontraditional users, there is an increased need for automated decision support to standardize results. We developed algorithms to evaluate the presence or absence of "B-lines" on thoracic sonography as a marker for interstitial fluid. ⋯ On the independent set, a perfect match was achieved. We believe that these are the first reported results in computerized B-line scoring.

Our aim with this study was to develop a user-friendly method for pediatric sonographically guided lumbar punctures so that we can visualize intrathecal anatomy, confirm intrathecal injection at the time of injection, and, most importantly, avoid ionizing radiation to a child's already radiosensitive pelvis. Sonographically guided lumbar puncture was prospectively performed in children aged 7 weeks to 16 years. ⋯ We were able to identify relevant anatomy (including the conus in children 10 years and younger), confirm intrathecal injection, visualize intrathecal hematoma, and avoid radiation. Sonography is a promising modality for image-guided lumbar punctures without radiation in children.

The primary purpose of this study was to describe and validate a novel sonographically guided costotransverse (CTRV) joint injection technique. ⋯ To our knowledge, this study is the first to determine the feasibility of sonographically guided CTRV joint injections. Overall, 68.8% of injection attempts produced acceptable CTRV joint arthrograms, which compares favorably to a previously reported 76% accuracy rate for fluoroscopically guided CTRV joint injections. Although these injections are technically challenging, the use of sonographic guidance to perform CTRV joint injections is feasible and warrants further investigation to establish its role in the management of patients presenting with thoracic pain syndromes.
