Pulmonary Embolism II: Diagnostic Studies and Interprofessional Care01:29

Pulmonary Embolism II: Diagnostic Studies and Interprofessional Care

31
Diagnosing Pulmonary EmbolismDiagnosing pulmonary embolism (PE) involves clinical assessment and advanced imaging tests. The preferred diagnostic tool is the spiral (helical) CT scan or CT angiography (CTA), which uses intravenous contrast media to visualize the pulmonary vasculature and identify emboli.A ventilation-perfusion (V/Q) scan is an alternative for patients unable to receive contrast media. This scan includes both perfusion and ventilation scanning. Perfusion scanning involves...

Imaging Studies for Cardiovascular System V: CT

57
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...

Computed Tomography

4.8K
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...

Radiological Investigation I: X-ray and CT

347
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...

Radiological Investigation III: Pulmonary Angiogram and PET Scan

143
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...

Imaging Studies for Cardiovascular System VI: Calcium -Scoring CT

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...

Summary

Routine contrast-enhanced chest CT scans can diagnose unsuspected pulmonary embolism (PE). Over a quarter of scans showed adequate pulmonary artery enhancement, including nearly half of PE-positive cases.

Area of Science:

  • Radiology
  • Cardiovascular Imaging
  • Pulmonary Medicine

Background:

  • Pulmonary embolism (PE) diagnosis often relies on specific imaging protocols.
  • Routine contrast-enhanced chest CT scans are widely performed for various indications.

Purpose of the Study:

  • To evaluate the utility of routine contrast-enhanced chest CT for diagnosing incidental pulmonary embolism (PE).
  • To assess the adequacy of pulmonary artery enhancement in these routine scans.

Main Methods:

  • Retrospective analysis of 3164 adult contrast-enhanced chest CTs from 2018.
  • Measurement of pulmonary artery enhancement using Hounsfield units (HU); adequate enhancement defined as ≥200 HU.
  • Statistical analysis including logistic regression to identify factors associated with enhancement and PE presence.

Main Results:

  • 28.7% of scans achieved adequate pulmonary artery enhancement (≥200 HU).
  • Factors associated with greater enhancement included female sex, older age, and higher contrast volume.
  • Pulmonary embolism was detected in 1.8% of cases, with 39.7% of these meeting the adequate enhancement threshold.

Conclusions:

  • A significant proportion of routine contrast-enhanced chest CTs provide adequate pulmonary artery enhancement for potential PE diagnosis.
  • Nearly half of PE-positive cases demonstrated sufficient enhancement, suggesting the value of reviewing these scans for unsuspected PE.
