Imaging Studies III: Computed Tomography

712
DefinitionComputed Tomography (CT) of the genitourinary (GU) tract is a non-invasive imaging modality that utilizes X-rays and computer processing to generate detailed cross-sectional images of the urinary system, encompassing the kidneys, ureters, bladder, and adjacent structures such as the adrenal glands.PurposeCT scans of the GU tract serve several diagnostic and therapeutic purposes, including:Diagnosis of Urinary Tract Diseases: Detects kidney stones, tumors, cysts, and congenital...

Imaging Studies for Cardiovascular System V: CT

581
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...

Radiological Investigation III: Pulmonary Angiogram and PET Scan

627
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...

Area of Science:

  • Urology
  • Radiology
  • Vascular Imaging

Background:

  • High-flow priapism is an uncommon urologic emergency often resulting from penile trauma and pseudoaneurysm formation.
  • Accurate identification of feeding vasculature is crucial for successful pre-procedural planning and embolization.
  • Conventional imaging may not always provide comprehensive three-dimensional visualization of the complex vascular supply.

Purpose of the Study:

  • To present a case of post-traumatic high-flow priapism evaluated using computed tomographic angiography (CTA).
  • To highlight the utility of CTA in delineating the anatomy of feeding vessels in high-flow priapism.
  • To establish CTA as a valuable diagnostic tool for this rare condition.

Main Methods:

  • A 26-year-old male patient with high-flow priapism secondary to trauma was evaluated.
  • Computed tomographic angiography was performed to visualize the penile vasculature.
  • The number, origin, and course of the pseudoaneurysmal feeding arteries were identified using CTA's three-dimensional reconstruction capabilities.

Main Results:

  • Computed tomographic angiography provided a detailed three-dimensional anatomical map of the feeding vessels supplying the pseudoaneurysm.
  • The imaging facilitated precise planning for subsequent embolization therapy.
  • This represents the first reported case of high-flow priapism evaluated with CTA.

Conclusions:

  • Computed tomographic angiography is a highly effective imaging modality for evaluating high-flow priapism.
  • CTA enables clear visualization of feeding vessels, crucial for guiding endovascular treatment.
  • This case underscores the diagnostic and planning benefits of CTA in managing this rare urologic condition.
