Imaging Studies for Cardiovascular System V: CT01:28

Imaging Studies for Cardiovascular System V: CT

65
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...

Radiological Investigation III: Pulmonary Angiogram and PET Scan

161
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...

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 VII: Vascular Imaging

52
DefinitionRenal angiography, also known as renal arteriography, is an imaging technique used to obtain a comprehensive view of blood flow and the vascular structure of blood vessels in the kidneys and surrounding areas.PurposeRenal angiography detects blood vessel abnormalities in the kidneys, such as aneurysms, stenosis, thrombosis, vascular tumors, and renal artery stenosis. It evaluates kidney function and guides interventional treatments like angioplasty or stent placement.Pre-Procedure...

Radiological Investigation II: MRI and Ventilation Perfusion Scan

216
Description
Magnetic Resonance Imaging (MRI) and Ventilation Perfusion Scans are two radiological investigations that offer detailed diagnostic images of the body, particularly lung structures.
MRI
MRI uses magnetic fields and radiofrequency signals to distinguish between normal and abnormal tissues. This technology provides a more detailed diagnostic image than CT scans, enabling it to characterize pulmonary nodules, stage bronchogenic carcinoma, and evaluate inflammatory activity in...

Imaging Studies for Cardiovascular System IV: CMRI

134
Cardiovascular magnetic resonance imaging, or CMRI, is a non-invasive diagnostic test that employs a magnetic field and radiofrequency waves to create precise images of the heart and arteries. It provides comprehensive information about cardiac anatomy, function, perfusion, and tissue characterization without ionizing radiation.IndicationsCMRI diagnoses various heart conditions, including tissue damage from heart attacks, ischemic heart disease, myocarditis, aortic issues (tears, aneurysms,...

Area of Science:

  • Pediatric Rheumatology
  • Vascular Inflammation
  • Diagnostic Imaging

Background:

  • Pediatric vasculitides are rare, heterogeneous disorders causing vessel inflammation.
  • Diagnosis is challenging due to nonspecific symptoms and lab markers.
  • Cardiothoracic involvement is common in these conditions.

Purpose of the Study:

  • To review major pediatric vasculitides with chest manifestations.
  • To highlight the critical role of imaging in diagnosis and monitoring.
  • To discuss clinical features and management strategies.

Main Methods:

  • Literature review of pediatric vasculitides.
  • Focus on conditions with frequent thoracic involvement.
  • Emphasis on imaging modalities and findings.

Main Results:

  • Identified key vasculitides: Takayasu arteritis, Kawasaki disease, GPA, EGPA, MPA, Behçet disease, and mimics.
  • Highlighted the importance of imaging for disease detection, extent, and complications.
  • Emphasized imaging's role in pre- and post-treatment monitoring.

Conclusions:

  • Imaging is indispensable for managing pediatric vasculitides with chest involvement.
  • Multimodality imaging aids in early diagnosis and long-term patient care.
  • A comprehensive understanding of imaging findings is essential for effective treatment.
