Description
An account of the resource
OBJECTIVES: There are conflicting results in the literature on the use of shear wave elastography of the kidney parenchyma to determine whether renal stiffness values are related to a disease process. This study was conducted to evaluate the raw data from 3 ultrasound systems and determine whether adequate displacement curves are obtained to accurately estimate shear wave speeds. METHODS: Shear wave elastography was performed on 5 healthy volunteers with 3 ultrasound systems. The raw data were collected and evaluated for the shear wave propagation quality to determine whether accurate estimates of renal shear wave speeds could be determined. RESULTS: Results from the 3 machines demonstrate that accurate shear wave displacement curves are not obtained with renal elastography on existing systems (as of June 2018). One vendor has recently released software that appears to acquire accurate shear wave displacements. CONCLUSIONS: Elastographic studies performed on the kidney to date are likely to be inaccurate. A new algorithm that appears to acquire accurate shear wave displacements in the kidney has been developed. Additional studies are needed to confirm that the new algorithm provides accurate clinical results. This study demonstrates that although the system provides a shear wave speed, it is important to confirm the accuracy of that number by evaluating the raw data.

Description
An account of the resource
Purpose: The objectives of the study were to evaluate the accuracy of the "bull's-eye" artifact of elasticity imaging (EI) in determining the benignity of cystic breast lesions and to determine the utility of such artifact in reducing the biopsy rate of the benign lesions. Methods: This study was performed under local institutional review board supervision and was in compliance with the Health Insurance Portability and Accountability Act of 1996. A retrospective review of 383 breast lesions from 309 consecutive patients undergoing diagnostic breast ultrasonography with EI (Siemens Antares or Siemens S2000; Siemens Healthcare, Mountain View, Calif) was conducted. The B-mode characteristics of those lesions determined whether biopsy was conducted. Pathological reports of the biopsied lesions were reviewed. Lesions demonstrating the bull's-eye artifact on EI were determined. The accuracy of the artifact in determining the benignity of cystic breast lesions was determined. Results: Of the 383 lesions, 243 lesions were recommended for biopsy based on the B-mode characteristics (biopsy rate, 63.4%). Of those 243 lesions, 62 lesions demonstrated the bull's-eye artifact on El, and all were confirmed benign cysts on pathological reports. Of the 181 lesions without the artifact, 116 were benign noncystic lesions, and 65 were malignant noncystic lesions. Hence, within the biopsied lesions, the bull's-eye artifact had perfect sensitivity, specificity, and positive predictive value in determining pathologically proven benign cysts. If the artifact can be used as a criterion to exclude lesions from biopsy, then the biopsy rate will be 181 (47.3%) of 383, significantly lower than the 63.4% biopsy rate without using this criteria (P< 0.001. Conclusions: The bull's-eye artifact seen on EI on Siemens ultrasonography equipment is a promising tool in the evaluation and characterization of benign breast cysts and has the potential to significantly reduce the amount of unnecessary breast biopsy.

Description
An account of the resource
PURPOSE: To evaluate the effects of 2 noise reduction techniques on the auditory brainstem response (ABR). METHOD: ABRs of 20 normal hearing adults were recorded during quiet and active behavioral conditions using 2 stimulus intensity levels. Wave V amplitudes and residual noise root-mean-square values were measured following the offline application of artifact rejection and Bayesian weighting. Repeated measures analysis of variance and Bonferroni adjusted pairwise t tests were utilized to evaluate significant main effects and interactions between the 2 noise reduction techniques. RESULTS: ABRs recorded during the quiet behavioral condition resulted in minimal differences in wave V amplitude and noise reduction improvement, suggesting that the 2 techniques were equally effective under ideal recording situations. During the active behavioral condition, however, the techniques differed significantly in the ability to preserve the evoked potential and reduce noise. Consequently, strict artifact rejection levels resulted in an inherent underestimation of wave V amplitudes when compared with the Bayesian approach. CONCLUSION: Artifact rejection had a detrimental effect on waveform morphology of the ABR. This could lead to difficulty in ABR interpretation when patients are active and ultimately result in diagnostic errors.

Description
An account of the resource
OBJECTIVES: Elastography of the breast is a new technique for characterization of breast lesions. The reproducibility of elastographic techniques has been questioned. Precompression is known to effect elastographic results. This study determined the effect of precompression on clinical images and proposes a method to semiquantify the amount of precompression applied. METHODS: Ten patients with different breast tissue types were evaluated with shear wave and strain elastography with varying amounts of precompression. The changes in the shear wave speed and images were documented. A semiquantitative method for determining the amount of precompression applied is presented. The reproducibility of the technique was determine by repeated measurements by 3 sonographers. RESULTS: Precompression substantially changes the elastographic results of patient images on both strain and shear wave elastography. Fat can have the same elasticity as cancer with clinically possible amounts of precompression. The proposed method for determining the amount of precompression applied has variability of less than 10%, which is within the error of the technique and would not affect clinical results. Four zones of precompression are identified, which are useful for explaining the effects of precompression on both strain and shear wave imaging. CONCLUSIONS: Precompression is a substantial factor in obtaining accurate results with elastography. A proposed simple, easily applied technique can be used to semiquantify the amount of precompression applied. Precompression should be minimized in obtaining breast clinical images.

Description
An account of the resource
The breast section of these Guidelines and Recommendations for Elastography produced under the auspices of the World Federation of Ultrasound in Medicine and Biology (WFUMB) assesses the clinically used applications of all forms of elastography used in breast imaging. The literature on various breast elastography techniques is reviewed, and recommendations are made on evidence-based results. Practical advice is given on how to perform and interpret breast elastography for optimal results, with emphasis placed on avoiding pitfalls. Artifacts are reviewed, and the clinical utility of some artifacts is discussed. Both strain and shear wave techniques have been shown to be highly accurate in characterizing breast lesions as benign or malignant. The relationship between the various techniques is discussed, and recommended interpretation based on a BI-RADS-like malignancy probability scale is provided. This document is intended to be used as a reference and to guide clinical users in a practical way.

Description
An account of the resource
Residual activity of chlorhexidine gluconate (CHG) was evaluated by pretreating hands with CHG and then touching Staphylococcus aureus dried on to stainless steel discs. By this method, no reduction in bacteria was observed up to 15 min, suggesting that residual CHG does not offer protection against contamination with transient micro-organisms in clinical practice.

Description
An account of the resource
Although contrast-enhanced ultrasound (CEUS) has become a widely utilized and accepted modality in much of the world, the associated contrast agents have only recently received approval in the United States. As with all radiological techniques, image artifacts are encountered in CEUS, some of which relate to commonly encountered ultrasound artifacts, while others are unique to this technique. Image artifacts must be recognized when performing and interpreting examinations to improve technique and diagnostic accuracy. In this article, we review artifacts that may be encountered in CEUS, and where possible discuss how to minimize them or mitigate their effect on image quality and interpretation.
