Pulmonary Embolism II: Diagnostic Studies and Interprofessional Care

Pulmonary Embolism II: Diagnostic Studies and Interprofessional Care

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...

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...

Pulmonary Edema II: Pathophysiology

Pulmonary Edema II: Pathophysiology

Pulmonary edema is the accumulation of fluid in the interstitial and alveolar spaces of the lungs, impairing gas exchange and oxygen delivery. It may be cardiogenic or noncardiogenic, but both reduce oxygenation and lung compliance.Cardiogenic Pulmonary EdemaCardiogenic edema results from increased hydrostatic pressure in pulmonary capillaries, usually due to left ventricular dysfunction from myocardial infarction, heart failure, or valvular disease. Ineffective cardiac pumping causes blood to...

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...

Pulmonary Embolism I: Introduction

Pulmonary Embolism I: Introduction

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...

Summary

This summary is machine-generated.

Postmortem CT (PMCT) lung imaging changes over time. Immediate PMCT is best for cause of death, while delayed PMCT better reflects autopsy findings.

Area of Science:

Forensic radiology
Postmortem imaging analysis
Pulmonary pathology

Background:

Postmortem CT (PMCT) is a valuable tool in forensic investigations.
Understanding time-dependent changes in PMCT findings is crucial for accurate interpretation.
This study investigates temporal variations in lung PMCT findings.

Observation:

Three non-traumatic deceased males underwent PMCT scans immediately and several hours postmortem.
Causes of death included acute cardiac insufficiency and ischemic heart disease.
Immediate and delayed lung PMCT scans were compared.

Findings:

Delayed PMCT demonstrated increased dependent opacity and consolidation compared to immediate scans.
These changes correlate with postmortem congestive pulmonary edema.
Time-dependent postmortem changes significantly alter lung PMCT appearance.

Implications:

Immediate PMCT is more effective for determining the cause of death.
Delayed PMCT provides a more accurate reflection of autopsy findings.
Accurate interpretation of PMCT requires consideration of the time elapsed since death.
