[Thoracic and abdominal imaging in immunocompromised patients]

Area of Science:

• Radiology
• Immunology
• Infectious Diseases

Background:

• The global increase in immunosuppressed patients leads to a higher incidence of opportunistic infections.
• Unspecific symptoms in these patients necessitate advanced diagnostic imaging.
• The lungs and abdomen are common sites for infections in immunocompromised individuals.

Purpose of the Study:

• To highlight the critical role of radiological imaging in managing immunosuppressed patients.
• To compare the diagnostic utility of chest X-ray and computed tomography (CT) for pulmonary infections.
• To emphasize CT's importance in abdominal diagnostics and interventional procedures.

Main Methods:

• Review of diagnostic imaging techniques for immunosuppressed patients.
• Comparison of chest X-ray sensitivity and specificity against CT for pulmonary infections.
• Evaluation of CT's role in abdominal assessment and image-guided interventions.

Main Results:

• Chest X-ray has limited sensitivity and specificity for atypical pathogens.
• Computed tomography (CT) provides better differentiation of viral, bacterial, and fungal infections, and non-infectious diseases.
• CT is essential for abdominal diagnostics, especially with inconclusive ultrasound findings, and enables interventions like biopsies and drainage.

Conclusions:

• Computed tomography (CT) is indispensable for diagnosing and managing infections in immunosuppressed patients.
• While CT aids in pathogen differentiation, exact pathogen identification remains a challenge.
• CT facilitates crucial diagnostic and therapeutic interventions in the abdomen for this patient group.
