Combination of transcranial ultrasound and susceptibility weighted imaging in diagnosis of Parkinsonism
To analyze the diagnostic value of combination of transcranial ultrasound (TCS) found substantia nigra hyperechogenicity (SN
+
) and susceptibility weighted imaging (SWI) found loss of "swallow tail sign" (LSTS
+
) to diagnose parkinsonism
and assess the clinical value of TCS and SWI in the diagnosis of Parkinson's disease (PD).
Methods
2
A total of 116 patients with parkinsonism admitted the Chongqing People's Hospital from July 2016 to December 2018 were recruited in this study. And 62 of them were in the PD group and 54 in the non-PD group. The image features of TCS for nigra and SWI were analyzed in these parkinsonism patients. With SN
+
found by TCS and LSTS
+
found by SWI as indicators
receiver operating characteristic (ROC) curve was used to analyze the sensitivity
specificity
and area under the curve (AUC) of the 2 examinations alone or combined together in diagnosis of PD.
Results
2
There were more patients with SN
+
by TCS or LSTS
+
by SWI in the PD patients than the non-PD patients. The sensitivity
specificity and AUC of diagnosis of by using SN
+
and LSTS
+
to diagnose PD were 80.6%
66.7%
0.737 and 88.7%
64.8%
0.768
respectively. However
the sensitivity and specificity and AUC of their combination for the diagnosis were 71.0%
88.9%
and 0.809.
Conclusion
2
In patients with parkinsonism
the results of TCS and SWI have similar efficacy in the diagnosis of PD
but TCS is better in economics and convenience. Although the sensitivity is decreased when the 2 examinations combine together
the specificity is greatly improved.
