Summary
Mobile tablet interpretation of brain CT scans for stroke is reliable. This technology ensures efficient and cost-effective telestroke services, improving patient care.
Area of Science:
- Neurology
- Radiology
- Medical Imaging
Background:
- Telestroke services are crucial for timely acute stroke patient care.
- Evaluating the reliability of mobile diagnostic tools is essential for expanding telestroke capabilities.
Purpose of the Study:
- To compare the reliability of brain CT interpretations using a diagnostic workstation versus a mobile tablet in a telestroke setting.
- To assess the diagnostic accuracy of mobile tablet interpretations for acute stroke assessment.
Main Methods:
- A factorial design involving 1,452 brain CT interpretations was employed.
- Reliability was assessed using Fleiss' kappa coefficient for lesion classification, contraindication identification for t-PA, and Alberta Stroke Program Early CT Score (ASPECTS).
Main Results:
- Good intra-observer agreement was found for overall lesion classification (κ=0.63) and dichotomized ASPECTS (κ=0.65).
- Very good agreement was observed for hemorrhagic lesions (κ=0.89), while moderate agreement was noted for non-acute and acute ischemic lesions.
- The mobile solution demonstrated reliable performance comparable to traditional workstations.
Conclusions:
- Mobile tablet-based interpretation of brain CT scans in telestroke is reliable.
- This mobile solution supports efficient and cost-effective telestroke services.
- The findings support the integration of mobile technology in acute stroke management.

Decision-making is a fundamental cognitive process that involves evaluating alternatives and selecting among them. This process can range from simple choices, such as deciding what to wear, to complex decisions, like choosing a major in college or a career path. The complexity of the decision often dictates the approach we use, which can be broadly categorized into two types: automatic and controlled decision-making.

01:09Decision Making: P-value Method
6.9K
The process of hypothesis testing based on the P-value method includes calculating the P- value using the sample data and interpreting it.
First, a specific claim about the population parameter is proposed. The claim is based on the research question and is stated in a simple form. Further, an opposing statement to the claim is also stated. These statements can act as null and alternative hypotheses: a null hypothesis would be a neutral statement while the alternative hypothesis can...

1.5K
In most substances, the current flow is proportional to the voltage applied to it. A simple relationship between the values of current, voltage, and resistance is known as Ohm's law. Nonohmic devices do not exhibit a linear relationship between voltage and current. One such device is the semiconducting circuit element known as a diode. A diode is a circuit device that allows current flow in only one direction.
Consider a simple circuit consisting of a battery, a diode, and a resistor. A...

409
Surveyors use Global Positioning System (GPS) technology to measure the precise location and elevation of points on Earth. In a recent survey, GPS receivers were used to determine the coordinates and elevations of two park monuments. The process involved careful mission planning, data collection, and correction to ensure accuracy. The survey began with mission planning to identify optimal satellite visibility and minimize Position Dilution of Precision (PDOP). A geodetic control point...
