Computed Tomography01:10

Computed Tomography

8.1K
Tomography refers to imaging by sections. Computed tomography (CT) is a non-invasive imaging technique that uses computers to analyze several cross-sectional X-rays to reveal minute details about structures in the body.
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...

DefinitionComputed Tomography (CT) of the genitourinary (GU) tract is a non-invasive imaging modality that utilizes X-rays and computer processing to generate detailed cross-sectional images of the urinary system, encompassing the kidneys, ureters, bladder, and adjacent structures such as the adrenal glands.PurposeCT scans of the GU tract serve several diagnostic and therapeutic purposes, including:Diagnosis of Urinary Tract Diseases: Detects kidney stones, tumors, cysts, and congenital...

Student t Distribution01:31

Student t Distribution

13.6K
The population standard deviation is rarely known in many day-to-day examples of statistics. When the sample sizes are large, it is easy to estimate the population standard deviation using a confidence interval, which provides results close enough to the original value. However, statisticians ran into problems when the sample size was small. A small sample size caused inaccuracies in the confidence interval.
The Student t distribution was developed by William S. Goset (1876–1937) of the...

Microsoft Excel: Student's t-Test

1.6K
Student's t-test in Microsoft Excel is a statistical method used to compare the means of two groups to determine if they are significantly different from each other. It's commonly used to evaluate hypotheses, such as testing whether a treatment has an effect compared to a control group. Excel provides built-in functions to perform t-tests, making it accessible for users needing to conduct basic statistical analysis.
To conduct a t-test in Excel, use the T.TEST function or the "Data...

Comparing Experimental Results: Student's t-Test

5.2K
The t-test is a statistical method used to compare the sample mean with a population mean or compare two means from two data sets. The test statistic is calculated from the standard deviation, mean, and number of measurements in the data set at a selected confidence interval and then compared to a table of critical values at this confidence level. If the test statistic is smaller than the critical value, the null hypothesis is accepted. In this case, we state that the difference between the...

Area of Science:

  • Medical Imaging Education
  • Radiography Training
  • Computed Tomography

Background:

  • Diagnostic radiography students receive computed tomography (CT) education during university coursework and clinical placements.
  • Enhancing CT education within university curricula is essential for effective training.
  • This review explores current CT teaching methods and assessment strategies for radiography students.

Purpose of the Study:

  • To explore the published literature on computed tomography (CT) teaching methods.
  • To investigate assessment strategies for diagnostic radiography students in CT education.
  • To inform the enhancement of CT education in university curricula.

Main Methods:

  • A narrative review of articles published in English from 2015-2025.
  • Searches conducted in Medline, CINAHL, and Web of Science databases.
  • Data extracted from 13 studies, summarized into themes of CT education methods, evaluation, and student assessment.

Main Results:

  • CT education predominantly occurs on-campus, with limited inclusion of clinical placements.
  • Tutorial-based approaches, CT scanners (direct/remote access), and virtual reality are common teaching methods.
  • Evaluation focuses on student knowledge and experience; assessment typically involves pre-post quizzes and reflective blogs.

Conclusions:

  • On-campus CT education enhances student knowledge, while clinical education is crucial for skill acquisition.
  • Guided learning during on-campus education boosts student knowledge and confidence.
  • Further investigation is required into CT education in clinical/academic settings and pre-graduation competency achievement.
