Ultrasonography01:17

Ultrasonography

8.4K
Ultrasonography is an imaging technique that uses high-frequency sound waves to visualize the body's internal structures. It is a non-invasive and safe procedure that does not involve the use of ionizing radiation, making it widely used in various medical fields. Ultrasonography is used to study heart function, blood flow in the neck or extremities, certain conditions such as gallbladder disease, and fetal growth and development.
During an ultrasonography procedure, a handheld device called...

Imaging Studies VII: Vascular Imaging

474
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...

Peripheral Arterial Disease II: Clinical Manifestations and Diagnostic Evaluation

669
Clinical manifestationsPeripheral Arterial Disease (PAD) manifests through a range of symptoms, from the characteristic intermittent claudication to atypical presentations and severe complications in advanced stages. Intermittent claudication, a hallmark symptom of PAD, presents as exercise-induced muscle pain that typically resolves within minutes of rest. This pain is reproducible and stems from inadequate blood flow, leading to the accumulation of lactic acid produced during anaerobic...

Imaging Studies for Cardiovascular System III: X-Ray

645
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...

Area of Science:

  • Rheumatology
  • Medical Imaging

Background:

  • Psoriatic arthritis (PsA) is a complex inflammatory joint disease associated with psoriasis.
  • PsA exhibits diverse clinical and radiological manifestations, impacting joints and entheses.
  • Accurate diagnosis and monitoring are crucial for effective PsA management.

Purpose of the Study:

  • To provide a comprehensive overview of current imaging modalities used in psoriatic arthritis.
  • To evaluate the advantages and limitations of radiography, ultrasonography (US), and magnetic resonance imaging (MRI) in PsA.
  • To highlight the role of imaging in the integrated management of PsA.

Main Methods:

  • Review of the literature on imaging in psoriatic arthritis.
  • Focus on conventional radiography, ultrasonography (US), and magnetic resonance imaging (MRI).
  • Discussion of the diagnostic capabilities and clinical utility of each modality.

Main Results:

  • Conventional radiography is useful for detecting chronic changes but limited in early disease.
  • Ultrasonography (US) excels at visualizing synovitis and enthesitis, offering dynamic assessment.
  • Magnetic resonance imaging (MRI) provides detailed soft tissue and bone marrow evaluation, crucial for early detection.

Conclusions:

  • Imaging plays a vital role in the diagnosis and management of psoriatic arthritis.
  • Each modality (radiography, US, MRI) offers unique insights into PsA pathology.
  • A multimodal imaging approach is often necessary for comprehensive PsA assessment.
