Lung Capacity01:47

Lung Capacity

50.5K
The air in the lungs is measured in volumes and capacities. Lung volume measures reflect the amount of air taken in, released, or left over after a lung function, like a single inhalation. Lung capacity measures are sums of two or more lung volume measures.

Radiological Investigation III: Pulmonary Angiogram and PET Scan

100
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

136
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:

  • Public Health
  • Oncology
  • Health Disparities

Background:

  • Rural and racial/ethnic minority communities face higher lung cancer risks and mortality.
  • Lung cancer screening using low-dose computed tomography (LDCT) is proven to reduce mortality.
  • Significant disparities in lung cancer screening uptake persist, particularly in marginalized populations.

Purpose of the Study:

  • To highlight the key barriers to lung cancer screening in rural and racial/ethnic minority communities.
  • To discuss the multilevel factors contributing to screening disparities.

Main Methods:

  • This is a discussion-based abstract, synthesizing existing knowledge on barriers.
  • Focuses on patient-level, provider-level, and system-level barriers.

Main Results:

  • Barriers to lung cancer screening are complex and multifaceted.
  • These barriers exist at individual, healthcare provider, and healthcare system levels.

Conclusions:

  • Understanding and addressing these multilevel barriers is essential for equitable lung cancer screening.
  • Targeted interventions are needed to reduce lung cancer mortality disparities in rural and minority populations.
