description Invasive pulmonary aspergillosis (IPA) is a life-threatening infection of immunocompromised patients with <i>Aspergillus fumigatus</i>, a ubiquitous environmental mould. While there are numerous functioning antifungal therapies, their high cost, substantial side effects and fear of overt resistance development preclude permanent prophylactic medication of risk-patients. Hence, a fast and definitive diagnosis of IPA is desirable, to quickly identify those patients that really require aggressive antimycotic treatment and to follow the course of the therapeutic intervention. However, despite decades of research into this issue, such a diagnostic procedure is still not available. Here, we discuss the array of currently available methods for IPA detection and their limits. We then show that molecular imaging using positron emission tomography (PET) combined with morphological computed tomography or magnetic imaging is highly promising to become a future non-invasive approach for IPA diagnosis and therapy monitoring, albeit still requiring thorough validation and relying on further acceptance and dissemination of the approach. Thereby, our approach using the <i>A. fumigatus</i>-specific humanized monoclonal antibody hJF5 labelled with <sup>64</sup>Cu as PET-tracer has proven highly effective in pre-clinical models and hence bears high potential for human application.
