A multi-criteria methodology for evaluating alternative ultrasound devices
No full textSeveral surveys and clinical studies report high prevalence of work-related musculoskeletal disorders (WMSDs) among sonographers and sonologists. Better performing ultrasound devices can increase the number and quality of examinations, but also reduce the user comfort and increase the risk of WMSDs. This should lead the choice of the device to buy and use. To support hospitals or diagnostic centres in selecting the best ultrasound device, this study provides a structured methodology based on a multi-criteria approach, the Analytic Hierarchy Process. It has a Goal (to optimise workers’ well-being and satisfy company production objectives) and 45 evaluation elements. It was applied in an Italian hospital comparing 3 alternatives: wireless, portable, and cart-based. The latter proved to be the best in satisfying the Goal, whereas a previous study obtained that the wireless device was preferable considering only the ergonomic point of view. The case study validated the applicability of the methodology.
Practitioner summary: This paper provides the decision-makers of hospitals or diagnostic centres with a multi-criteria methodology to select the best ultrasound device capable of optimising workers’ well-being and satisfying company production objectives. The methodology can also support manufacturers of ultrasound devices in improving their products

No full textColor Doppler Ultrasound in Portal Hypertension: A Closer Look at Left Gastric Vein Hemodynamics
No full textPortal hypertension is one of the most important causes of morbidity and mortality in cirrhotic patients. A color Doppler evaluation of the left gastric vein (LGV) has proven utility in the prediction of esophageal varices and variceal bleeding in patients with portal hypertension. The purpose of this review is to discuss the ultrasound evaluation, imaging findings, and clinical application of Doppler ultrasound in the assessment of the LGV. Knowledge of the color Doppler technique and imaging findings of the LGV may help clinicians improve the monitoring of portal hypertension and predict patients with a high risk of esophageal varices
