Imaging Studies VII: Vascular Imaging01:19

Imaging Studies VII: Vascular Imaging

31
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...

Imaging Studies for Cardiovascular System IV: CMRI

60
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,...

Imaging Studies for Cardiovascular System V: CT

41
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...

Imaging Studies for Cardiovascular System III: X-Ray

216
The most common cardiovascular diagnostic test is an X-ray. It produces images of the heart, blood vessels, and adjacent structures.
Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...

Imaging Studies V: Intravenous Urography and Retrograde Pyelography

55
IntroductionIntravenous Urography (IVU) and Retrograde Pyelography (RP) are important diagnostic imaging techniques used to evaluate the urinary system. These methods help identify structural abnormalities, obstructions, and functional issues in the kidneys, ureters, and bladder. Both procedures use iodine-based contrast media to enhance the visibility of urinary tract structures on X-ray images, though they differ in their methods and indications.1. Intravenous Urography (IVU)Intravenous...

Radiological Investigation III: Pulmonary Angiogram and PET Scan01:13

Radiological Investigation III: Pulmonary Angiogram and PET Scan

114
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...

Area of Science:

  • Rheumatology and Internal Medicine
  • Vascular Imaging
  • Diagnostic Modalities

Context:

  • Giant cell arteritis (GCA) and Takayasu arteritis (TAK) are primary large vessel vasculitides.
  • Diagnosis confirmation is crucial to prevent ischemic complications.
  • Unspecific symptoms in extracranial GCA and TAK necessitate reliable diagnostic methods.

Purpose:

  • To review the current status of imaging techniques for large vessel vasculitis.
  • To discuss the advantages and disadvantages of various imaging modalities.
  • To highlight ultrasound as a primary diagnostic tool for GCA and TAK.

Summary:

  • Imaging is recommended by EULAR as an alternative to histology for diagnosing GCA and TAK since 2018.
  • Ultrasound is the preferred modality for cranial GCA and valuable for extracranial GCA.
  • MRI, PET, and CT are alternative imaging options, with ultrasound favored for its quality, availability, and noninvasiveness.

Impact:

  • Provides a comprehensive overview of imaging in large vessel vasculitis.
  • Emphasizes the growing role and benefits of ultrasound in diagnosing GCA and TAK.
  • Discusses future developments like disease progression scores and contrast-enhanced ultrasound.
