Imaging Studies VII: Vascular Imaging

536
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 V: CT

631
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 IV: CMRI

557
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 V: Intravenous Urography and Retrograde Pyelography

3.2K
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.

Imaging Studies for Cardiovascular System III: X-Ray

699
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 I: Kidney, Ureter, and Bladder Studies

807
Kidney, Ureter, and Bladder (KUB) StudiesKidney, Ureter, and Bladder (KUB) studies are standard diagnostic imaging procedures used to assess the anatomy of the urinary system. They are commonly utilized for patients experiencing abdominal pain or urinary symptoms. By using a simple X-ray of the abdomen, KUB studies can reveal structural and pathological abnormalities within the kidneys, ureters, and bladder. These studies are particularly valuable in diagnosing kidney stones, urinary...

Area of Science:

  • Rheumatology
  • Radiology
  • Internal Medicine

Background:

  • Systemic vasculitis diagnosis and management rely heavily on clinical assessment.
  • Imaging modalities are increasingly vital for evaluating disease extent and activity.

Purpose of the Study:

  • To review recent advancements in imaging for systemic vasculitis.
  • To highlight data with potential clinical impact on diagnosis, disease extent, and management.

Main Methods:

  • Review of current literature on imaging techniques in systemic vasculitis.
  • Focus on data from color duplex ultrasonography (CDUS), computed tomography angiography (CTA), and positron emission tomography (PET).

Main Results:

  • CDUS is valuable for giant-cell arteritis diagnosis, though early inflammation may be missed.
  • CTA reveals large-vessel involvement in most giant-cell arteritis patients at diagnosis.
  • PET shows promise for assessing large-vessel inflammation and disease extent in various vasculitides.

Conclusions:

  • Emerging imaging techniques are poised to significantly impact systemic vasculitis care.
  • These advancements will aid in diagnosis, disease extent appraisal, activity evaluation, and treatment response assessment.
