Computed Tomography01:10

Computed Tomography

9.0K
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...

In the field of psychology, there are several ways to organize measurements of a trait, feature, or characteristic (i.e., variables). Qualitative data, such as ethnicity, can be tabulated into a frequency count to provide information about the proportion, as well as the variety of groups in a sample or population. On the other hand, researchers can perform a wider set of calculations on quantitative data. The mean, mode, and median, for instance, are central tendency measures to identify a...

Gas Chromatography: Types of Detectors-I

1.7K
There are different types of detectors used in gas chromatography, each with its own specific properties that make it suitable for detecting certain types of analytes. The most commonly used detectors in GC are thermal conductivity detector (TCD), flame ionization detector (FID), and electron capture detector (ECD).
TCD is the earliest and most widely used detector that operates by measuring the changes in the thermal conductivity of the carrier gas. When a sample compound enters the detector,...

Gas Chromatography: Overview of Detectors

2.1K
Detectors in gas chromatography (GC) help identify and quantify the components of a mixture by translating chemical properties into measurable signals, which are displayed on a chromatogram. Detectors can be categorized into two main types: destructive and non-destructive.
A non-destructive detector allows a sample to be analyzed without altering or consuming it, meaning the sample can be collected after detection for further analysis. Examples include thermal conductivity detectors and...

In gas chromatography, different detectors are employed to meet specific analytical needs. These detectors are often categorized based on their detection mechanisms and the types of compounds they are best suited to analyze. Thermal Conductivity Detectors (TCD), Flame Ionization Detectors (FID), and Electron Capture Detectors (ECD) represent common categories, each with unique operating principles and applications. However, beyond these, several other detectors are designed for more specialized...

Summary
This summary is machine-generated.

Computed Tomography (CT) effectively visualizes the normal appendix, with enhanced CT showing a 97% visualization rate. Normal appendix diameter on CT can exceed 6 mm, challenging ultrasound criteria for appendicitis.

Area of Science:

  • Radiology
  • Medical Imaging
  • Gastrointestinal Imaging

Background:

  • The appendix is a blind-ended tubular structure originating from the cecum.
  • Acute appendicitis is a frequent reason for emergency radiological assessment.

Purpose of the Study:

  • To evaluate the visualization rate, size, and position of the normal appendix using Computed Tomography (CT).

Main Methods:

  • A cross-sectional observational study involving 198 individuals undergoing abdominal CT.
  • Evaluation of nonenhanced and contrast-enhanced CT images for appendix visualization, localization, and intraluminal content.
  • Measurement of appendicular diameter and analysis of its relationship with age, gender, and position.

Main Results:

  • Appendix visualization rates were 90% with nonenhanced CT and 97% with enhanced CT.
  • The mean appendix diameter was 6.2 ± 1.16 mm, with pelvic and retrocecal positions being most common.
  • Intraluminal air was the most frequent finding within the appendix lumen.

Conclusions:

  • Multi-Detector Computed Tomography (MDCT) offers superior appendix visualization compared to ultrasonography (USG).
  • CT protocols can be modified to overcome limitations compared to ultrasound for appendix evaluation.
  • The >6 mm diameter criterion for appendicitis on ultrasound is not directly applicable to normal appendix measurements on CT.
