Imaging of the diaphragm: anatomy and function

Area of Science:

• Medical Imaging
• Pulmonology
• Anatomy

Background:

• The diaphragm is essential for breathing.
• Diaphragm dysfunction can cause significant respiratory problems.
• Causes include surgery, trauma, tumors, and infections.

Purpose of the Study:

• To highlight diaphragm dysfunction as an underappreciated cause of respiratory difficulties.
• To describe diagnostic methods for diaphragmatic dysfunction.
• To classify types of diaphragmatic dysfunction and discuss treatment options.

Main Methods:

• Review of clinical presentations and imaging findings of diaphragmatic dysfunction.
• Utilizing functional imaging modalities such as fluoroscopy, ultrasonography, and MRI.
• Classification of dysfunction into paralysis, weakness, and eventration based on imaging characteristics.

Main Results:

• Diaphragmatic disease often presents as diaphragmatic elevation on chest radiography.
• Functional imaging is effective in diagnosing diaphragmatic dysfunction.
• Specific imaging findings differentiate paralysis, weakness, and eventration.

Conclusions:

• Diaphragm dysfunction is a critical, often overlooked, cause of respiratory distress.
• Functional imaging is crucial for accurate diagnosis.
• Treatment strategies, including plication and phrenic nerve stimulation, are available for diaphragmatic paralysis.
