Parkinson’s disease: Diagnosis using radiology

Parkinson’s disease is one of the most common neurological disorders in Germany, particularly amongst people over the age of 60. Early diagnosis plays a crucial role in slowing the progression of the disease and maintaining the quality of life of those affected. Modern radiological techniques such as nuclear medicine and DaT-SPECT (Single Photon Emission Computed Tomography) can provide valuable support in this regard.

Parkinson’s disease is a degenerative neurological disorder that affects the central nervous system. The gradual loss of dopamine-producing nerve cells in the brain leads to the development of motor and non-motor symptoms.

• Trembling of the limbs (tremor)

• Muscle stiffness (rigidity)

• Slowed movements (bradykinesia)

• Speech and swallowing difficulties

• In addition, generalised symptoms such as sleep problems, muscle and joint pain, and memory problems may occur.

An early diagnosis is crucial, as it forms the basis for targeted treatment that can slow the progression of the disease and improve the quality of life of those affected.

To diagnose Parkinson’s disease, functional diagnostic tests are carried out. Two main procedures are used: DaT-SPECT, which is a nuclear medicine technique, and MRI (magnetic resonance imaging).

The DaT-SPECT scan makes it possible to distinguish Parkinson’s tremor from other conditions with similar symptoms. A contrast agent makes the dopamine-containing nerve cells in the brain visible. If fewer signals are detectable in a specific region of the brain, particularly the striatum, this suggests Parkinson’s disease.

An MRI scan may be used as a supplementary investigation, particularly in cases of atypical symptoms or unclear findings. Imaging helps to rule out other causes of the symptoms and to establish a differentiated initial diagnosis. Nevertheless, DaT-SPECT is currently the preferred method, as it provides a more detailed picture of the dopamine system and lays the foundation for further treatment.

An early diagnosis of Parkinson’s disease makes it possible to treat the condition more effectively and maintain patients’ quality of life. DaT-SPECT and MRI are important radiological techniques that aid in making a clear and precise diagnosis. If you or a relative notice symptoms of Parkinson’s disease, please consult experienced specialists in radiology or nuclear medicine to facilitate an early assessment.
