The purpose of this presentation is to review the sonographic spectrum of disease entities evaluated by right upper quadrant (RUQ) sonography on an emergent basis. ⋯ Right upper quadrant sonography is the first line of imaging in patients with signs and symptoms of hepatic, gallbladder, or biliary disease as well as RUQ pain. Patient triage or additional imaging may be obtained on the basis of emergent RUQ sonographic findings.

Randomized Controlled Trial
Use of urokinase in percutaneous drainage of large breast abscesses.
The purpose of this study was to evaluate intracavitary urokinase therapy versus irrigation with a saline solution in percutaneous drainage of large breast abscesses. ⋯ Percutaneous drainage of large breast abscesses in nonlactating women with intracavitary urokinase irrigation is a simple and safe procedure. It reduces the treatment time and improves the clinical course of patients more than conventional drainage with saline irrigation.

Clinical Trial
Accuracy of sonographically guided intra-articular injections in the native adult hip.
The purpose of this study was to determine the accuracy of sonographically guided intra-articular injections performed in the native adult hip using contrast-enhanced fluoroscopy as a reference standard. ⋯ Sonographic guidance can be used to inject the native adult hip joint with acceptable accuracy. When using the oblique sagittal approach, operators must be aware of the possibility of needle withdrawal from the joint due to the limited intra-articular space within the target region, particularly in the absence of effusion.

Nerve stimulator-assisted localization of the femoral nerve is well described; however, direct ultrasound imaging of the femoral nerve branches may be challenging. The purpose of this study was to correlate the evoked motor responses obtained by femoral nerve stimulation and the topographic orientation of the femoral nerve branches during ultrasound examinations of the infrainguinal region. ⋯ When using out-of-plane ultrasound imaging at the inguinal crease, directing the stimulating needle to the lateral half of the femoral nerve may be associated with a higher probability of encountering the motor branch to the quadriceps muscle.

Review Meta Analysis
Sonographic interstitial syndrome: the sound of lung water.
Ultrasound lung comets (ULCs) now have an acknowledged correlation with extravascular lung water, but they present in different orders and numbers in different pathologic pulmonary entities. How these artifacts are created is not yet known, and the literature gives discordant hypotheses. Understanding their formation is the first step in understanding lung disease. The purpose of this study was to show the morphologic and genetic variability of interstitial lung disease studied with echography and thus to propose a unitary mechanism for the formation of ULCs. ⋯ Reverberation between bubbles with a critical radius seems to be at the origin of ring-down artifacts. Echographic manifestations of interstitial lung disease, whose genesis lies in the partial air loss of lobes and segments, are acoustic phenomena originating from variations in the tissue-fluid relationship of the lung. A correlation between anatomopathologic characteristics and structures of sonographic artifacts could allow more rapid and noninvasive diagnoses.
