Comparative Study
Comparison of sonographically guided intra-articular injections at 3 different sites of the knee.
Sonographically guided injections show more accuracy than blind injections, but there are no reports comparing sonographically guided intra-articular injection approaches. This study examined the accuracy of sonographically guided intra-articular injections at 3 different sites of the knee using medial, midlateral, and superolateral portals. ⋯ Sonographically guided intra-articular injections in the midlateral or superolateral portal may increase the accuracy of knee joint injections.

The purpose of this study was to investigate the sensitivity and diagnostic value of convex probe endobronchial sonographically guided transbronchial needle aspiration (EBUS-TBNA) in the diagnosis of granulomatous mediastinal lymphadenitis. ⋯ In the diagnosis of granulomatous lymphadenitis, EBUS-TBNA, with high sensitivity and a minimum complication rate, is an alternative to mediastinoscopy.

The purpose of this study was to determine and compare the accuracies of sonographically guided and palpation guided scaphotrapeziotrapezoid (STT) joint injections in a cadaveric model. ⋯ Sonographic guidance can be used to inject the STT joint with a high degree of accuracy and is more accurate than palpation guidance within the limits of this study design. Clinicians should consider using sonographic guidance to perform STT joint injections when precise intra-articular placement is desired. Further clinical investigation examining the role of sonographically guided STT joint injections in the treatment of patients with radial wrist pain syndromes is warranted.

The purposes of this study were to identify the frequency of the color "line sign" after track coagulation during electrode removal and to evaluate the usefulness of color Doppler sonography in predicting complications after radiofrequency ablation. ⋯ There is a decreased frequency of the color line sign and hemorrhagic complications after radiofrequency ablation compared to their rates of occurrence with core biopsy. Identification of the color line sign may be useful for predicting hemorrhagic complications.

As the use of point-of-care sonography spreads, so too does the need for remote expert over-reading via telesonogrpahy. We sought to assess the feasibility of using familiar, widespread, and cost-effective existent technology to allow remote over-reading of sonograms in real time and to compare 4 different methods of transmission and communication for both the feasibility of transmission and image quality. ⋯ Wireless transmission of sonographic video clips using inexpensive hardware, free videoconferencing software, and domestic Internet networks is feasible with retention of image quality sufficient for interpretation. WiFi transmission results in greater image quality than transmission by a 3G network.
