Imaging Studies I: CT and MRI

Imaging Studies I: CT and MRI

Introduction: MRI and CT scans are crucial advancements in medical imaging techniques, playing a vital role in diagnosing conditions related to the gastrointestinal (GI) system. Each scan serves distinct purposes, targets specific areas, and requires unique nursing duties.
Description of the Procedures
Computed Tomography (CT) scan:
Computed Tomography (CT) scans use X-ray technology to generate detailed images of bones, organs, and tissues. During the scan, the patient lies on a moving table...

Radiological Investigation I: X-ray and CT

Radiological Investigation I: X-ray and CT

Radiological investigations, including X-rays and computed tomography (CT) scans, are critical for diagnosing and evaluating various medical conditions. These imaging techniques provide valuable insights into the body's internal structures, aiding in the detection of abnormalities, assessment of disease progression, and development of treatment strategies. This article delves into two primary radiological investigations, chest X-rays and CT scans, outlining their purpose, procedures, and the...

Imaging Studies for Cardiovascular System V: CT

Imaging Studies for Cardiovascular System V: CT

Cardiac computed tomography (CT) scanning is an advanced cardiac imaging technique that utilizes CT technology, with or without intravenous (IV) contrast, to produce accurate cross-sectional virtual slices of specific areas of the heart, coronary circulation, and major blood vessels such as the aorta, pulmonary veins, and arteries. The computer processes these slices to generate three-dimensional images. Multidetector CT (MDCT) is a rapid form of CT scanning that captures multiple slices...

Radiological Investigation III: Pulmonary Angiogram and PET Scan

Radiological Investigation III: Pulmonary Angiogram and PET Scan

Radiological investigations are paramount in the diagnosis and management of various pulmonary diseases. Two essential investigations are the Pulmonary Angiogram and the Positron Emission Tomography (PET) Scan.
Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...

Computed Tomography

Computed Tomography

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...

Imaging Studies III: Computed Tomography

Imaging Studies III: Computed Tomography

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...

Summary

SNOMED CT covers most terms in pre-operative assessment guidelines, but vagueness in guidelines reduces coverage. Improving SNOMED CT requires addressing guideline ambiguity and adding missing concepts for better decision support.

Area of Science:

Medical Informatics
Clinical Terminology
Health Services Research

Background:

Pre-operative assessment guidelines are crucial for patient care.
Standardized terminology is essential for effective clinical decision support systems.
Systematized Nomenclature of Medicine - Clinical Terms (SNOMED CT) is a widely used medical terminology.

Purpose of the Study:

To evaluate the coverage of terms from pre-operative assessment guidelines within SNOMED CT.
To identify areas for improvement in SNOMED CT content for pre-operative assessment.

Main Methods:

Guidelines from anesthesia societies were analyzed.
Recommendations were converted into "IF condition THEN action" statements.
Extracted terms were mapped to SNOMED CT, measuring coverage (complete, partial, none).

Main Results:

71% of 133 extracted terms had a complete match in SNOMED CT.
Excluding vague terms, SNOMED CT coverage reached 89%.
Non-covered concepts often violated SNOMED CT editorial principles (e.g., vagueness, numeric ranges).

Conclusions:

Vague terms in guidelines hinder representation in terminological systems like SNOMED CT.
Addressing guideline vagueness and enhancing SNOMED CT are necessary for improved decision support.
Formalizing guidelines with SNOMED CT is feasible but requires content refinement.
