Adaptations in Nuclear Neurology Procedures for Elderly Patients: A Survey of Nuclear Medicine Technologists in Portugal.

The increase in life expectancy has raised the incidence of neurologic diseases among the elderly, resulting in greater demand for nuclear neurology examinations and a need to adapt procedures to meet these specific needs. This study aimed to assess the adaptation of nuclear neurology procedures performed in Portugal and, through questionnaires directed at nuclear medicine technologists (NMTs), identify the most common adaptations. Methods: An online questionnaire was distributed to NMTs in clinical practice, excluding those in commercial, production, or research settings. The questionnaire investigated NMTs' adaptations in patient preparation, positioning, and image acquisition for the elderly population. Results: Responses from 17 NMTs were collected and revealed that nuclear neurology procedures are infrequent (41.2%), with Parkinson disease dementia and Lewy body dementia being the most common clinical indications (23.5% each). Cerebral perfusion scintigraphy and dopaminergic transporter or receptor assessments were the most frequently performed examinations (17.6% each). Adaptations were not routinely applied, but when needed, dialogue and family involvement (76.5%) were used. Positioning challenges were noted by 64.7%, with 29.4% using immobilization accessories. PET/CT scans were preferred by 41.2% for their speed and diagnostic quality. Conclusion: Clear communication, family participation, and the use of immobilization aids key to maintaining image quality and patient comfort in elderly populations. Adapting imaging protocols and prioritizing faster modalities may improve diagnostic outcomes and patient care.
