Parkinson's disease belongs to the most prevalent neurodegenerative disorders and manifests both with motor and non-motor symptoms. Symptomatic treatment of this disorder became more multifaceted over the past years: besides classical dopaminergic drugs and physiotherapy, novel invasive escalation treatment strategies became gold standard in many countries. On the other hand, non-motor symptoms significantly impacts quality of life in many patients which necessitates initiation of adequate therapy.

Computed tomography (CT) is one of the most commonly performed imaging modalities in radiology. This is mainly the result of wide availability, robustness, and fast image acquisition. However, CT is associated with ionizing radiation to the patients. ⋯ These include automated attenuation-based tube current modulation and automated selection of the tube voltage. In addition, iterative reconstruction techniques allow for a dramatic decrease in radiation dose while image quality can be maintained. Using all these techniques, it has become possible to perform a diagnostic CT examination of the lungs with a radiation dose that is comparable to that of a conventional chest X-ray.
