Radiological Investigation III: Pulmonary Angiogram and PET Scan01:13

Radiological Investigation III: Pulmonary Angiogram and PET Scan

88
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

105
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...

Area of Science:

  • Oncology
  • Public Health
  • Biomarker Research

Background:

  • Lung cancer is a leading global cause of cancer death.
  • Lung cancer screening can significantly reduce mortality rates.
  • Current screening practices face challenges and require improvement.

Purpose of the Study:

  • To review major issues in current lung cancer screening.
  • To discuss the potential role of biomarkers in improving screening.
  • To address challenges like ethnic disparity and emerging risk factors.

Main Methods:

  • Literature review of lung cancer screening programs.
  • Analysis of real-world screening data and outcomes.
  • Evaluation of the current state and future potential of biomarkers.

Main Results:

  • Lung cancer screening effectiveness is established but has room for improvement.
  • Ethnic disparities and novel risk factors (beyond smoking/asbestos) impact screening.
  • Biomarkers are promising for objective risk assessment but not yet clinically ready.

Conclusions:

  • Lung cancer screening is crucial but requires addressing disparities and new risks.
  • Biomarkers hold significant potential to enhance lung cancer screening objectivity.
  • Further research is needed to integrate biomarkers into clinical practice for lung cancer screening.
