Radiological Investigation II: MRI and Ventilation Perfusion Scan01:30

Radiological Investigation II: MRI and Ventilation Perfusion Scan

364
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...

Radiological Investigation III: Pulmonary Angiogram and PET Scan

276
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 I: X-ray and CT

869
Radiological investigations, including X-rays and computed tomography (CT) scans, are critical for diagnosing and evaluating various medical conditions. These imaging techniques provide valuable insights into the body's internal structures, aiding in the detection of abnormalities, assessment of disease progression, and development of treatment strategies. This article delves into two primary radiological investigations, chest X-rays and CT scans, outlining their purpose, procedures, and...

Imaging Studies for Cardiovascular System III: X-Ray

376
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...

Summary

Emerging lung function imaging uses four-dimensional CT (4DCT) to create ventilation maps, aiding radiation oncology by identifying functional lung areas for precise treatment and toxicity reduction.

Area of Science:

  • Medical Imaging
  • Radiation Oncology
  • Pulmonary Function Assessment

Background:

  • Four-dimensional CT (4DCT) is standard for lung cancer treatment planning.
  • CT-based ventilation (CT-ventilation) imaging offers functional lung insights without additional patient procedures.
  • CT-ventilation research has advanced from methodology to clinical utility validation.

Purpose of the Study:

  • To review the methodologies, validation, and clinical applications of CT-ventilation imaging.
  • To explore CT-ventilation's role in functional avoidance radiation therapy and dose-response assessment.
  • To summarize ongoing clinical trials and discuss future directions for CT-ventilation.

Main Methods:

  • Utilizes phase-resolved 4DCT images and image processing to generate lung ventilation maps.
