Imaging Studies VII: Vascular Imaging01:19

Imaging Studies VII: Vascular Imaging

100
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...

Radiological Investigation III: Pulmonary Angiogram and PET Scan

199
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...

Imaging Studies V: Intravenous Urography and Retrograde Pyelography

327
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...

Endoscopic Procedures V: ERCP

1.2K
Endoscopic Retrograde Cholangiopancreatography (ERCP) is a diagnostic procedure that combines endoscopy and fluoroscopy to diagnose and treat conditions related to the bile ducts, pancreatic ducts, and gallbladder. This procedure is beneficial for identifying and addressing blockages, gallstones, strictures, and tumors within the biliary or pancreatic systems. ERCP is both diagnostic and therapeutic, offering the ability to visualize and treat identified problems in one session.

Imaging Studies II: Ultrasonography

89
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...

Pulmonary Embolism II: Diagnostic Studies and Interprofessional Care

75
Diagnosing Pulmonary EmbolismDiagnosing pulmonary embolism (PE) involves clinical assessment and advanced imaging tests. The preferred diagnostic tool is the spiral (helical) CT scan or CT angiography (CTA), which uses intravenous contrast media to visualize the pulmonary vasculature and identify emboli.A ventilation-perfusion (V/Q) scan is an alternative for patients unable to receive contrast media. This scan includes both perfusion and ventilation scanning. Perfusion scanning involves...

Summary

Prostatic artery embolization (PAE) is a minimally invasive treatment for benign prostatic hyperplasia (BPH). Proper pre- and post-procedural imaging evaluations are crucial for successful PAE outcomes in managing lower urinary tract symptoms.

Area of Science:

  • Interventional Radiology
  • Urology
  • Medical Imaging

Background:

  • Benign prostatic hyperplasia (BPH) causes lower urinary tract symptoms (LUTS), impacting quality of life.
  • Established BPH treatments include medications and surgery.
  • Prostatic artery embolization (PAE) is an emerging minimally invasive option for BPH.

Purpose of the Study:

  • To inform radiologists and interventional radiologists about PAE technical concepts.
  • To highlight key imaging features for pre- and post-procedural PAE assessments.
  • To emphasize the importance of comprehensive evaluations for successful PAE.

Main Methods:

  • Review of technical aspects of PAE for BPH.
  • Discussion of essential pre-procedural evaluations (clinical, laboratory, imaging).
  • Outline of post-procedural assessment requirements, including imaging (US, MRI, CT).

Main Results:

  • PAE is increasingly utilized in tertiary care settings for BPH.
  • Successful PAE relies on thorough pre- and post-procedural imaging interpretation.
  • Radiologists must understand PAE nuances for accurate reporting.

Conclusions:

  • PAE offers a viable minimally invasive treatment for BPH with moderate to severe LUTS.
  • Radiologists play a critical role in patient selection and treatment monitoring via imaging.
  • Awareness of PAE techniques and imaging hallmarks is essential for interventional radiologists.
