OBJECTIVES: To compare the agreement and interobserver variability of diagnostic handheld ultrasound (US) and a single volume on an automated breast volume scanner (ABVS) and to determine whether there was a significant difference if the ABVS was used by a sonographer or mammographic technologist. METHODS: Ninety patients scheduled for diagnostic US examinations were randomized to either handheld US or the ABVS first. The AVBS was randomized between a sonographer and a mammographic technologist performing the study. The studies were blinded, randomized, and read by 2 radiologists. The lesion with the highest Breast Imaging Reporting and Data System (BI-RADS) score was used in the analysis. Final diagnoses were made by core biopsy or follow-up for 2 years. Lesions included 9 malignant and 81 benign. RESULTS: The 90 patients had a mean age +/- SD of 53.1 +/- 16.3 years. The kappa value for agreement between the ABVS and handheld US was 0.831 (95% confidence interval, 0.744-0.925), whereas the global agreement for a 7-point BI-RADS score was 0.488 (0.372-0.560). The agreement between the ABVS and handheld US was nearly the same when the ABVS was used by a mammographic technologist (kappa = 0.858 [0.723-0.963]) or sonographer (kappa = 0.803 [0.596-1.000]; P = .47). The areas under the receiver operating characteristic curves for characterization by the ABVS were 0.91 (0.84-0.96) for reader 1 and 0.91 (0.83-0.96) for reader 2; those for handheld US were 0.91 (0.84-0.96) for reader 1 and 0.83 (0.74-0.90) for reader 2, with no statistical difference. The agreement based on pathologic images was kappa = 0.831 (0.718-0.944); for handheld US, kappa = 0.795 (0.623-0.967); and for the AVBS, kappa = 0.869 (0.725-1.000). CONCLUSIONS: Performing a single-view diagnostic ABVS examination has good agreement with a handheld diagnostic US workup. There is no difference if the ABVS is used by a sonographer or mammographic technologist.

Description
An account of the resource
There are 3 methods of interpreting breast strain elastography: the elastographic-to-B-mode length ratio (E/B), a 5-point color scale (5P), and the strain ratio (SR). This meta-analysis assessed which method is superior to the others. A systematic search of the medical literature was performed in July 2017. Studies were eligible for inclusion if they fulfilled the following criteria: (1) had biopsy-proven or long-term stability as the reference standard; (2) used either the E/B, 5P, or SR to interpret results; and (3) had at least 50 cases. A total of 220 records were retrieved; 60 full-text articles were examined, and 46 were included in the meta-analysis. Publication years ranged from 2007 and 2017. The quality of studies was generally high. The mean age of women was 48 years; 12,398 lesions (4242 malignant) were analyzed. For the 5P method, the sensitivity was 77%; specificity, 87%; positive likelihood ratio (LR), 5.3; and negative LR, 0.24. For the SR method, sensitivity was 87%; specificity, 81%; positive LR, 4.8; and negative LR, 0.16. For the E/B method, sensitivity was 96%; specificity, 88%; positive LR, 7.1; and negative LR, 0.03. Of the 3 methods, the E/B had the highest sensitivity, and the E/B and 5P had the highest specificity. With a negative LR of 0.03, the E/B method can downgrade lesions with a pretest probability of 50% to a 2% probability of malignancy.

Description
An account of the resource
AIM: The primary aim of this study was to determine the inter-system variability of liver stiffness measurements (LSMs) in patients with varying degrees of liver stiffness. The secondary aim was to determine the inter-observer variability of measurements. MATERIALS AND METHODS: 21 individuals affected by chronic hepatitis C and 5 healthy individuals were prospectively enrolled. The assessment of LSMs was performed using six ultrasound (US) systems, four of which with point shear wave elastography (p-SWE) and two with 2 D shear wave elastography (2D-SWE) systems. The Fibroscan (Echosens, France) was used as the reference standard. Four observers performed the measurements in pairs (A-B, C-D). The agreement between different observers or methods was calculated using Lin's concordance correlation coefficient. The Bland-Altman limits of agreement (LOA) were calculated as well. RESULTS: There was agreement above 0.80 for all pairs of systems. The mean difference between the values of the systems with 2D-SWE technique was 1.54 kPa, whereas the maximum mean difference between the values of three out of four systems with the pSWE technique was 0.79 kPa. The intra-patient concordance for all systems was 0.89 (95 % CI: 0.83 - 0.94). Inter-observer agreement was 0.96 (95 % CI: 0.94 - 0.98) for the pair of observers A-B and 0.93 (95 % CI: 0.89 - 0.96) for the pair of observers C-D. CONCLUSION: The results of this study show that the agreement between LSMs performed with different US systems is good to excellent and the overall inter-observer agreement in "ideal conditions" is above 0.90 in expert hands.
