Current status on imaging invasive fungal infections with positron emission tomography

Area of Science:

• Medical Imaging
• Nuclear Medicine
• Infectious Diseases

Background:

• Fungal infections pose a significant health challenge, necessitating advanced diagnostic tools.
• Positron emission tomography integrated with computed tomography (PET/CT) is increasingly utilized for evaluating invasive fungal infections in both clinical and preclinical settings.
• While Fluorodeoxyglucose (FDG) PET/CT shows growing clinical evidence, limitations persist, driving the search for improved imaging agents.

Purpose of the Study:

• To review the current applications of positron emission tomography in the diagnosis and management of invasive fungal infections.
• To highlight the ongoing efforts in developing novel, fungal-specific PET tracers.
• To discuss the potential of PET imaging in assessing fungal burden and guiding treatment strategies.

Main Methods:

• Literature review of studies utilizing PET imaging for fungal infections.
• Analysis of current clinical and preclinical data on FDG PET/CT efficacy.
• Exploration of emerging PET tracers for fungal disease detection.

Main Results:

• FDG PET/CT has demonstrated utility in identifying fungal infections, though specificity can be a challenge.
• Several novel PET tracers are under investigation at the preclinical level for their potential in fungal imaging.
• The development of fungal-specific tracers is a key area of research for improved diagnostic accuracy.

Conclusions:

• Positron emission tomography offers valuable insights into invasive fungal infections.
• Further research into fungal-specific PET tracers is crucial for enhancing diagnostic capabilities and patient care.
• PET imaging holds promise for more precise assessment of fungal disease burden.
