Imaging Studies for Cardiovascular System V: CT

556
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...

Computed Tomography

9.5K
Tomography refers to imaging by sections. Computed tomography (CT) is a non-invasive imaging technique that uses computers to analyze several cross-sectional X-rays to reveal minute details about structures in the body.
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...

Radiological Investigation III: Pulmonary Angiogram and PET Scan

621
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...

Radiological Investigation II: MRI and Ventilation Perfusion Scan

Description
Magnetic Resonance Imaging (MRI) and Ventilation Perfusion Scans are two radiological investigations that offer detailed diagnostic images of the body, particularly lung structures.
MRI
MRI uses magnetic fields and radiofrequency signals to distinguish between normal and abnormal tissues. This technology provides a more detailed diagnostic image than CT scans, enabling it to characterize pulmonary nodules, stage bronchogenic carcinoma, and evaluate inflammatory activity in...

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...

Summary

Lowering radiation dose in abdominal CT angiography is possible. An 80kV/400mAs protocol reduces radiation by 50% without significantly impacting image quality (signal-to-noise ratio).

Area of Science:

  • Radiology
  • Medical Imaging
  • Radiation Dose Reduction

Background:

  • Computed Tomography Angiography (CTA) is crucial for diagnosing abdominal aortic aneurysms (AAA).
  • Optimizing radiation dose while maintaining diagnostic image quality is a key challenge in CTA.
  • Lowering radiation exposure is essential for patient safety and reducing cumulative risks.

Purpose of the Study:

  • To evaluate the effectiveness of different dose reduction algorithms in abdominal CTA.
  • To compare standard 120kV protocols with lower 80kV protocols at varying mAs settings.
  • To assess the impact of dose reduction on radiation dose, aortic attenuation, and signal-to-noise ratio (S/N).

Main Methods:

  • A prospective, randomized, crossover study involving 60 patients undergoing abdominal CTA.
  • Patients received a standard 120kV scan followed by an 80kV scan with varying mAs (300, 400, or 500mAs).
  • Radiation dose, aortic attenuation, noise, and S/N ratio were systematically measured and compared between protocols.

Main Results:

  • The 80kV protocols significantly reduced radiation dose compared to the 120kV standard (e.g., 80kV/400mAs resulted in ~5.0 mSv vs. 9.7 mSv).
  • Aortic attenuation and S/N ratio were significantly higher with 80kV protocols across all groups (p<0.05).
  • The 80kV/400mAs protocol demonstrated a substantial dose reduction with comparable or improved image quality metrics.

Conclusions:

  • The 80kV/400mAs protocol offers a significant radiation dose reduction of approximately 50% in abdominal CTA.
  • This lower kV protocol achieves this dose reduction without a significant compromise in the signal-to-noise ratio.
  • The findings support the use of 80kV protocols for dose optimization in abdominal CTA.
