Pulmonary Embolism II: Diagnostic Studies and Interprofessional Care

221
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...

Acute Coronary Syndrome III: Diagnostic Studies

154
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...

Pulmonary Embolism I: Introduction

426
Pulmonary embolism (PE) occurs when a thrombus, fat or air embolus, amniotic fluid, or tumor tissue blocks one or more pulmonary arteries. These blockages originate in the venous system or the right side of the heart.EtiologyPE primarily arises from deep vein thrombosis (DVT) and other hypercoagulable states, such as inherited thrombophilias. Additional etiological factors include venous stasis, commonly seen in obesity, and endothelial injury from surgery and trauma. Less common causes include...

Radiological Investigation III: Pulmonary Angiogram and PET Scan

337
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

309
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...

Imaging Studies for Cardiovascular System V: CT

206
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...

Area of Science:

  • Cardiovascular Imaging
  • Medical Informatics
  • Radiology

Background:

  • Acute pulmonary embolism (PE) is a common cardiovascular disease.
  • Computer-aided detection (CAD) is crucial in chest imaging for PE assessment.
  • Reliability and quantitative analysis of CAD techniques are essential for clinical application.

Purpose of the Study:

  • To evaluate the reliability of a geometry-based CAD system for detecting and quantifying emboli morphology and severity in acute PE.
  • To compare the accuracy and efficiency of CAD versus manual interpretation for PE assessment.

Main Methods:

  • Thirty patients with suspected acute PE underwent both manual and CAD interpretation.
  • Vascular obstruction index, Qanadli score, and Mastora score were assessed.
  • CAD measurements of emboli quantitative parameters were obtained.
  • Reliability was analyzed using intraclass correlation coefficient (ICC).

Main Results:

  • CAD significantly reduced interpretation time (121.07±51.76s) compared to manual methods (374.90±150.16s) (P<0.001).
  • High agreement was found between CAD and manual interpretations for Qanadli score (ICC=0.998) and Mastora score (ICC=0.997).
  • Emboli quantitative parameters showed moderate correlation with established scoring systems (P<0.001).

Conclusions:

  • Geometry-based CAD is a reliable tool for assessing acute PE.
  • CAD reduces interpretation time and improves the reliability of vascular obstruction index assessment.
  • CAD provides additional quantitative parameters, enhancing disease assessment for acute pulmonary embolism.
