As an alternative to automated extraction, fecal specimens were processed by investigational lysis/heating (i.e., manual) and by chromatography/centrifugation (i.e., column) methods. ProGastro SSC and Shiga toxin-producing Escherichia coli (i.e., STEC) indeterminate rates for 101 specimens were 1.0% to 3.0% for automated, 11.9% for manual, and 24.8% to 37.6% for column methods. Following freeze...

OBJECTIVE This study investigated the reliability, accuracy, and time efficiency of automated hearing assessment using a computer-based telemedicine-compliant audiometer. MATERIALS AND METHODS Thirty normal-hearing subjects and eight hearing-impaired subjects were tested with pure-tone air conduction audiometry (125-8,000 Hz) in a manual and automated configuration in a counterbalanced manner...

OBJECTIVE The purpose of this study was to evaluate automated CT volumetry in the assessment of living-donor livers for transplant and to compare this technique with software-aided interactive volumetry and manual volumetry. MATERIALS AND METHODS Hepatic CT scans of 18 consecutively registered prospective liver donors were obtained under a liver transplant protocol. Automated liver volumetry ...

This study is a method comparison of three region-of-interest (ROI) tracing approaches. fMRI images acquired during an event-related frequency discrimination task were used in this study. Three [(1) manual, (2) semi-automated, (3) automated] approaches were applied to generate the ROI in the caudate nucleus and extract fMRI hemodynamic response (HR) from the ROI. Less activation with weak and d...

BACKGROUND An automated sphygmomanometer, the BpTRU, was used in a blood pressure (BP) survey of 2,551 residents in the province of Ontario. Automated BP readings were compared with measurements taken by a mercury sphygmomanometer under standardized conditions in a random 10% sample. METHODS BP was recorded in 238 individuals in random order using both a standard mercury device and an automat...
