Insights

Pulmonary embolism (PE) and deep venous thrombosis (DVT) are part of venous thromboembolic disease (VTE). CT pulmonary arteriography (CTPA) and computed tomography venography (CTV) offer a single noninvasive test to diagnose both PE and DVT.

Area of Science:

  • Radiology
  • Cardiovascular Medicine
  • Diagnostic Imaging

Background:

  • Pulmonary embolism (PE) and deep venous thrombosis (DVT) are manifestations of venous thromboembolic disease (VTE).
  • VTE is frequently underestimated, underdiagnosed, and undertreated.
  • Accurate diagnosis is crucial for effective management.

Purpose of the Study:

  • To review the epidemiology of VTE.
  • To outline the diagnostic algorithm for suspected VTE.
  • To detail CT pulmonary arteriography (CTPA) and computed tomography venography (CTV) protocols and interpretation.

Main Methods:

  • Review of existing literature on VTE epidemiology and diagnosis.
  • Description of CTPA and CTV techniques.
  • Discussion of image interpretation challenges.

Main Results:

  • CTPA combined with CTV provides a single noninvasive method for evaluating both PE and DVT.
  • The review covers diagnostic algorithms and specific imaging protocols.
  • Challenges in interpreting CTPA for radiologists are highlighted.

Conclusions:

  • CTPA and CTV represent a significant advancement in the noninvasive diagnosis of VTE.
  • Standardized protocols and interpretation guidelines are essential for optimal use.
  • Improved diagnostic capabilities may lead to better VTE management.

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...

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...

Inflammatory Bowel Disease II: Crohn's Disease

Introduction
Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.
Crohn's disease
Crohn's disease is a chronic, systemic inflammatory bowel disease (IBD) that predominantly affects the gastrointestinal tract. It is marked by...

Immunodeficiency Diseases01:25

Immunodeficiency Diseases

Immunodeficiency disorders are conditions in which the immune system's ability to fight infectious disease and cancer is compromised or entirely absent. The immune system comprises a complex network of cells, tissues, and organs that work together to protect the body from potentially harmful invaders. When this system is deficient or not functioning properly, it leaves the body susceptible to infections, diseases, or other complications.
There are three main causes of immunodeficiency...
