Imaging Studies VII: Vascular Imaging

383
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...

German physicist Wilhelm Röntgen (1845–1923) was experimenting with electrical current when he discovered that a mysterious and invisible "ray" would pass through his flesh but leave an outline of his bones on a screen coated with a metal compound. In 1895, Röntgen made the first durable record of the internal parts of a living human: an "X-ray" image (as it came to be called) of his wife’s hand. Scientists worldwide quickly began their own experiments with...

Introduction:Magnetic Resonance Imaging, or MRI, can include a specialized imaging technique of the urinary system known as Magnetic Resonance Urography (MRU). This radiation-free technique uses strong magnetic fields and radio waves to produce detailed images with the help of a computer. MRU is particularly effective for visualizing fluid-filled structures like the kidneys, ureters, and bladder.Applications of MRI in the Genitourinary SystemKidneys and Ureters: MRI detects tumors, cysts,...

Magnetic resonance imaging (MRI) is a noninvasive medical imaging technique based on a phenomenon of nuclear physics discovered in the 1930s, in which matter exposed to magnetic fields and radio waves was found to emit radio signals. In 1970, a physician and researcher named Raymond Damadian noticed that malignant (cancerous) tissue gave off different signals than normal body tissue. He applied for a patent for the first MRI scanning device in clinical use by the early 1980s. The early MRI...

IntroductionUltrasonography, or renal ultrasound, is a noninvasive medical imaging technique that uses high-frequency sound waves to visualize the kidneys, ureters, bladder, and surrounding tissues.Indications for Urinary System UltrasonographyUrinary system ultrasonography is indicated in various clinical scenarios, such as:Kidney Stones (Urolithiasis): To detect and monitor the size and presence of kidney or urinary tract stones.Hydronephrosis: To assess the dilation of the renal pelvis and...

Area of Science:

  • Rheumatology
  • Medical Imaging
  • Inflammatory Disorders

Background:

  • Polymyalgia rheumatica (PMR) is a chronic inflammatory condition of unknown etiology.
  • It presents with pain and morning stiffness, primarily affecting the shoulders, pelvic girdle, and neck.
  • Extra-articular structures are significantly involved in PMR.

Purpose of the Study:

  • To review the diagnostic and follow-up utility of various imaging modalities in Polymyalgia Rheumatica.
  • To emphasize the specific roles of ultrasound, PET/CT, and MRI in managing PMR patients.

Main Methods:

  • Literature review of studies on imaging techniques in Polymyalgia Rheumatica.
  • Analysis of the contribution of ultrasound, PET/CT, and MRI to PMR diagnosis and management.
  • Synthesis of current evidence on imaging's role in defining PMR pathology.

Main Results:

  • Imaging techniques have been crucial in identifying PMR as a disease affecting extra-articular structures.
  • Ultrasound demonstrates synovitis and bursitis, aiding early diagnosis.
  • PET/CT and MRI provide insights into inflammation extent and activity, valuable for monitoring treatment response.

Conclusions:

  • Imaging plays a pivotal role in the diagnosis and follow-up of Polymyalgia Rheumatica.
  • Ultrasound, PET/CT, and MRI are essential tools for assessing PMR, improving patient management.
  • Further research can refine the application of these imaging techniques in clinical practice.
