Imaging is an important part of diagnosing and monitoring fungal infections, especially when combined with mycological evidence. For good reviews with lots of informative images please see:
- Starkey et al (2014) MRI of CNS Fungal Infections: Review of Aspergillosis to Histoplasmosis and Everything in Between
- Walker et al (2014) Imaging Pulmonary Infection: Classic Signs and Patterns
- Orlowski et al (2017) Imaging Spectrum of Invasive Fungal and Fungal-like Infections
Setting the correct parameters for CT and MR scanning requires radiological expertise. Likewise interpretation is critical and can be difficult. Radiological imaging cannot make a precise mycological diagnosis but usually contributes greatly to a full understanding of the extent of disease and its treatment. Mistaken radiological diagnosis does occasionally occur, primarily because a wide differential diagnosis is not considered initially, and some fungal infections are rare.
We also have a page dedicated to imaging.

Choosing a modality
|Central nervous system||MRI||Un-enhanced CT||CT scanning is insensitive and contrast often not given because of renal dysfunction. Unenhanced CT scan almost useless|
|Lung fungal infection in leukaemia or after haematopoietic stem cell treatment (HSCT)||CT||X-ray||Chest radiograph misses at least 10% of patients and is imprecise in the number and size of lesions|
|ABPA||CT||X-ray||Chest radiograph is insensitive with respect to the complications bronchiectasis and chronic pulmonary aspergillosis|
|Sinus||CT||X-ray||Sinus radiograph insensitive, especially for ethmoid and sphenoid disease|
