Computed Tomography01:10

Computed Tomography

4.6K
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...

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...

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...

Calcium-Scoring CT ScanA calcium-scoring CT scan, also known as coronary artery calcium (CAC) scan, detects calcium deposits in the coronary arteries. This test assesses the risk of coronary artery disease (CAD), which can lead to cardiovascular events such as angina, heart failure, and sudden cardiac arrest.A calcium-scoring CT scan is generally recommended for individuals at intermediate risk of CAD without symptoms. It includes:Men aged 40-75 and women aged 50-75: Especially those with a...

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...

Diagnosing acute coronary syndrome or ACS begins with a thorough patient history. Notable symptoms include central, crushing chest pain radiating to the left arm, neck, jaw, or back, along with shortness of breath, sweating (diaphoresis), nausea, vomiting, dizziness, and palpitations.It is crucial to note any history of cardiac illnesses and assess risk factors, including age, gender, smoking, hypertension, diabetes, hyperlipidemia, and a sedentary lifestyle.During physical examination, vital...

Summary

Computed tomography (CT) scans are used less often in freestanding emergency departments (FSEDs) than hospital-based emergency departments (HBEDs) for patients with chest pain. This study analyzed CT utilization rates for chest pain in FSEDs versus HBEDs.

Area of Science:

  • Emergency Medicine
  • Radiology
  • Health Services Research

Background:

  • Computed tomography (CT) is a key diagnostic tool in emergency departments (EDs) for evaluating serious conditions.
  • Freestanding emergency departments (FSEDs) offer an alternative to traditional hospital-based emergency departments (HBEDs).
  • Understanding CT utilization patterns in different ED settings is crucial for patient care and resource allocation.

Purpose of the Study:

  • To compare the utilization rates of CT scans for patients presenting with chest pain between FSEDs and HBEDs.
  • To identify potential disparities in diagnostic imaging between freestanding and hospital-based emergency care.

Main Methods:

  • Retrospective analysis of 67,084 patient encounters with chest pain from May 2019 to April 2021.
  • Data collected from 17 emergency departments within a large integrated healthcare system.
  • Multiple logistic regression used to control for patient factors (comorbidity index, ESI, age, sex, race) and assess facility type's effect on CT utilization.

Main Results:

  • Patients presenting with chest pain to FSEDs were less likely to undergo CT scans compared to those in HBEDs (Adjusted Odds Ratio = 0.85, 95% CI [0.81-0.90]).
  • The study controlled for significant predictive variables, isolating the impact of the facility type.
  • Demographic data showed a predominantly female (55%), white (61%) patient population insured by Medicare/Medicaid (59%).

Conclusions:

  • CT scans of the chest are underutilized in FSEDs relative to HBEDs for patients presenting with chest pain.
  • This finding suggests a potential difference in diagnostic imaging practices between freestanding and hospital-based emergency care settings.
