Imaging Studies for Cardiovascular System III: X-Ray01:20

Imaging Studies for Cardiovascular System III: X-Ray

670
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...

Radiological Investigation III: Pulmonary Angiogram and PET Scan

642
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 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...

Area of Science:

  • Interventional Radiology
  • Medical Imaging Technology
  • Radiation Oncology

Background:

  • Transarterial chemoembolization (TCE) involves radiation exposure.
  • Optimizing imaging technology is crucial for reducing patient radiation dose.
  • Previous methods lacked sufficient dose reduction capabilities.

Purpose of the Study:

  • To evaluate radiation dose reduction in TCE patients using a novel image acquisition and processing platform.
  • To assess the impact of the new platform on radiation dose indicators.
  • To determine if image quality is maintained with the new technology.

Main Methods:

  • 176 TCE procedures in 135 patients were analyzed.
  • Data collected before and after upgrading to a new imaging platform.
  • Radiation dose metrics (CDAP, CAK) and fluoroscopy time were recorded.
  • Image quality was assessed by blinded interventional radiologists.

Main Results:

  • Mean cumulative dose-area product (CDAP) reduced by 45.9% (P < .00001).
  • Mean cumulative air kerma (CAK) decreased by 32.8% (P < .0001).
  • Fluoroscopy time increased by 20.3%, but image quality remained undegraded.

Conclusions:

  • The optimized imaging platform significantly reduces patient radiation dose during TCE.
  • The dose reduction was achieved without compromising diagnostic image quality.
  • This technology offers a safer approach for chemoembolization procedures.
