Imaging Studies VII: Vascular Imaging01:19

Imaging Studies VII: Vascular Imaging

80
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

81
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...

Echocardiography plays a role in assessing cardiac health and detecting heart conditions, with various types providing critical insights for diagnosis and treatment.
Types of Echocardiography
Transthoracic Echocardiography (TTE)
TTE is the most common type of echocardiogram which involves placing a transducer on the patient's chest, emitting sound waves to create heart images. TTE is invaluable for evaluating the heart's size, structure, and motion, making it particularly useful for...

Venous Thrombosis II: Clinical Manifestations and Diagnostic Studies

50
The key difference between Superficial Vein Thrombosis (SVT) and Deep Vein Thrombosis (DVT) lies in their location and severity.Clinical ManifestationsSVT typically presents with localized pain, tenderness, and redness along the course of a superficial vein, often accompanied by a palpable, cord-like structure under the skin. This condition is usually less dangerous than DVT but can be uncomfortable and may lead to complications such as cellulitis or, rarely, a clot extension into the deep...

Varicose Veins II: Diagnostic Studies and Interprofessional Care01:26

Varicose Veins II: Diagnostic Studies and Interprofessional Care

41
Varicose veins, or varicosities, develop when the valves in the veins, which control blood flow, weaken or damage. It causes blood to pool and the veins to enlarge. Understanding the clinical manifestations, diagnostic approaches, and management options for varicose veins is crucial for effective treatment and relief.Clinical manifestationsClinical manifestations of varicose veins include a heavy, achy feeling or pain after prolonged standing or sitting. This discomfort can often be relieved by...

Imaging Studies VI: Voiding Cystourethrography and Cystography

191
Voiding Cystourethrography (VCUG) and Cystography are specialized radiographic procedures used to examine the structure and function of the bladder and urethra.Voiding Cystourethrography (VCUG)A Voiding Cystourethrogram (VCUG) is a diagnostic imaging procedure that assesses the anatomy and function of the lower urinary tract. It focuses on the bladder, bladder neck, and urethra, helping detect abnormalities such as vesicoureteral reflux (VUR)—the backward or reverse flow of urine into the...

Area of Science:

  • Vascular Surgery
  • Radiology
  • Medical Terminology

Background:

  • Ambiguity in terminology for vascular malformations and tumors is common.
  • Incorrect usage of terms like hemangioma and arteriovenous malformation (AVM) leads to diagnostic and management challenges.

Purpose of the Study:

  • To establish correct nomenclature for vascular anomalies.
  • To guide physicians and radiologists in diagnosing and managing these lesions.
  • To address the lack of diagnostic clinico-radiological features and imaging guidelines in current classifications.

Main Methods:

  • Review of existing classification systems for vascular anomalies.
  • Focus on the latest International Society for the Study of Vascular Anomalies (ISSVA) classification (revised 2018).
  • Analysis of diagnostic features and imaging modality guidelines.

Main Results:

  • Highlights key features of the latest ISSVA classification.
  • Identifies gaps in current classifications regarding diagnostic criteria and imaging recommendations.
  • Aims to provide clarity on correct terminology and usage.

Conclusions:

  • Standardized nomenclature is essential for effective communication in vascular anomaly diagnosis and management.
  • Further guidelines are needed for clinico-radiological features and imaging modalities.
  • This review aims to bridge the gap in current literature.
