Ultrasonography01:17

Ultrasonography

7.6K
Ultrasonography is an imaging technique that uses high-frequency sound waves to visualize the body's internal structures. It is a non-invasive and safe procedure that does not involve the use of ionizing radiation, making it widely used in various medical fields. Ultrasonography is used to study heart function, blood flow in the neck or extremities, certain conditions such as gallbladder disease, and fetal growth and development.
During an ultrasonography procedure, a handheld device called...

Reliability and Validity01:29

Reliability and Validity

13.9K
Reliability and validity are two important considerations that must be made with any type of data collection. Reliability refers to the ability to consistently produce a given result. In the context of psychological research, this would mean that any instruments or tools used to collect data do so in consistent, reproducible ways.

Design Example: Analyzing Capacity Contours for Flood Risk Assessment

326
Flood risk assessment involves careful planning and analysis to ensure the safety of communities near water retention structures. Capacity contours are a vital tool in this process, as they illustrate the potential spread of water at specific levels in a given area. In the context of building a bund across a small valley, these contours play a critical role in evaluating the safety of nearby residential areas.In this example, the bund is intended to store stormwater in the valley. The engineers...

Measurement: Standard Units03:38

Measurement: Standard Units

79.9K
Every measurement provides three kinds of information: the size or magnitude of the measurement (a number), a standard of comparison for the measurement (a unit), and an indication of the uncertainty of the measurement. While the number and unit are explicitly represented when a quantity is written, the uncertainty is an aspect of the errors in the measurement results.

Ultrasound I: Abdominal Ultrasonography01:20

Ultrasound I: Abdominal Ultrasonography

1.6K
Introduction:
Abdominal ultrasonography, commonly known as abdominal ultrasound, is a vital, non-invasive medical imaging technique widely used in healthcare.
Procedure:
This diagnostic tool allows the clinician to visually inspect internal structures within the abdomen, including vital organs such as the liver, gallbladder, pancreas, kidneys, and spleen.
The abdominal ultrasound process begins with applying a special gel to the patient's skin over the abdomen. This gel enhances the...

Area of Science:

  • Gynecologic oncology
  • Medical imaging
  • Ultrasound diagnostics

Background:

  • Ovarian cancer risk assessment often lacks standardization.
  • Ultrasonography is a key tool for evaluating adnexal masses.
  • Consistent reporting is crucial for accurate risk stratification.

Purpose of the Study:

  • To evaluate a standardized system for ovarian cancer risk assessment and reporting in ultrasonography.
  • To determine the performance of a four-category risk stratification system for adnexal masses.

Main Methods:

  • Prospective community-based cohort study of average-risk women undergoing ultrasonography.
  • Adnexal masses categorized into 1, 2, 3, or X based on standardized ultrasound criteria (size, solid components, vascularity).
  • Median follow-up of 18 months to determine cancer diagnosis risk for each category.

Main Results:

  • Among 43,606 women, 16% had abnormal adnexal masses.
  • Ovarian cancer risks for categories 1-X ranged from 0.2% to 13.0%.
  • Risks for ovarian cancer or borderline tumors ranged from 0.4% to 18.9% across categories.

Conclusions:

  • The standardized system effectively differentiates adnexal masses into distinct risk categories.
  • Approximately 9-10% of women had higher-risk masses, while 70% had low-risk findings.
  • The system provides consistent, risk-based assessments supporting clinical management.
