PET Predicts Survival in Atypical Parkinsonian Syndrome
FDG-PET provides physicians with survival predictions for patients with suspected atypical Parkinsonian syndrome.
FDG-PET can predict survival of patients with clinically suspected atypical Parkinsonian syndrome (APS), according to a study published in The Journal of Nuclear Medicine.
Researchers from Germany investigated the prognostic value of using FDG-PET compared with clinical diagnosis among patients with APS. Seventy-eight patients with suspected APS were enrolled in the study. All underwent initial FDG-PET imaging and were followed for 5.9 years. Of these patients, 44 were diagnosed with APS and 34 with Lewy body disease. Forty-four patients were still alive at 4.7 months (median) follow-up.
The results showed that patients who had been diagnosed with APS by PET or at one-year clinical follow-up had a median survival time of only 4.1 years, while the remaining patients, with Lewy body disease, had yet to reach median survival time.
The researchers concluded that use of FDG-PET provided an early predictor of survival in patients with clinically suspected APS. “This finding strongly supports the early inclusion of PET imaging in patient care,” they wrote.
Can Radiomics Bolster Low-Dose CT Prognostic Assessment for High-Risk Lung Adenocarcinoma?
December 16th 2024A CT-based radiomic model offered over 10 percent higher specificity and positive predictive value for high-risk lung adenocarcinoma in comparison to a radiographic model, according to external validation testing in a recent study.

Study Shows Merits of CTA-Derived Quantitative Flow Ratio in Predicting MACE
December 11th 2024For patients with suspected or known coronary artery disease (CAD) without percutaneous coronary intervention (PCI), researchers found that those with a normal CTA-derived quantitative flow ratio (CT-QFR) had a 22 percent higher MACE-free survival rate.
