Imagine trying to solve a puzzle, but only getting half of the pieces. That’s been the challenge with diagnosing Parkinson’s disease using a heart scan called myocardial MIBG scintigraphy. It was missing crucial information. But scientists have discovered that by combining this heart scan with another one that looks at the major salivary glands, they can finally see the full picture. These combined scans showed impressive accuracy in distinguishing Parkinson’s patients from non-Parkinson’s individuals. The salivary gland scan alone provided valuable information, but when combined with the heart scan, it became a powerful tool for diagnosis. The researchers found that the earlier the scans were done, the better the accuracy. This breakthrough has the potential to greatly improve the diagnostic process for Parkinson’s disease.

BackgroundDecreased myocardial uptake of 131I-metaiodobenzylguanidine (MIBG) is known to be an important feature to diagnose Parkinson’s disease (PD). However, the diagnosis accuracy of myocardial MIBG scintigraphy alone is often unsatisfying. Recent studies have found that the MIBG uptake of the major salivary glands was reduced in PD patients as well.PurposeTo evaluate the diagnostic value of major salivary gland MIBG scintigraphy in PD, and explore the potential role of myocardial MIBG scintigraphy combined with salivary gland MIBG scintigraphy in distinguishing PD from non-PD (NPD).MethodsThirty-seven subjects were performed with 131I-MIBG scintigraphy. They were classified into the PD group (N = 18) and the NPD group (N = 19), based on clinical diagnostic criteria, DAT PET and 18F-FDG PET imaging findings. Images of salivary glands and myocardium were outlined to calculated the MIBG uptake ratios.ResultsThe combination of left parotid and left submandibular gland early images had a good performance in distinguishing PD from NPD, with sensitivity, specificity, and accuracy of 50.00, 94.74, and 72.37%, respectively. Combining the major salivary gland and myocardial scintigraphy results in the early period showed a good diagnostic value with AUC, sensitivity and specificity of 0.877, 77.78, and 94.74%, respectively. Meanwhile, in the delayed period yield an excellent diagnostic value with AUC, sensitivity and specificity of 0.904, 88.89, and 84.21%, respectively.Conclusion131I-MIBG salivary gland scintigraphy assisted in the diagnosis and differential diagnosis of PD. The combination of major salivary gland and myocardial 131I-MIBG scintigraphy further increased the accuracy of PD diagnosis.
