摘要

背景迄今为止，18F-氟脱氧葡萄糖（FDG）正电子发射断层扫描（PET）在进行性核上性麻痹（PSP）中的研究通常包括理查森综合征（PSP-RS）患者的PSP队列。目的评估FDG-PET在代表常规临床实践中常见的广泛表型PSP谱的患者样本中的表现。方法这项回顾性多中心研究包括41名PSP患者，21名（51%）患有RS，20名（49%）患有PSP的非RS变体，以及46名年龄匹配的健康对照。比较了FDG-PET的两种最先进的解释方法：基于体素的统计测试支持的视觉分析（五个阅读器）和使用预定义PSP相关模式的自动协方差模式分析。结果在整个队列中，大多数视觉读数对PSP检测的敏感性和特异性分别为74%和72%。PSP-RS子样本中假阴性病例的百分比为10%，vSP子样本中为43%。在整个队列中，自动协方差模式分析的敏感性和特异性分别为93%和83%。PSP-RS子样本中假阴性病例的百分比为0%，vSP子样本中为15%。结论基于体素检测支持的FDG-PET视觉判读为PSP-RS的检测提供了良好的准确性，但对vSP的敏感性较差。自动协方差模式分析在检测PSP-RS方面优于视觉解释，为vSP提供了临床有用的灵敏度，并降低了假阳性发现率。因此，模式表达分析在临床上有助于补充可疑PSP中FDG-PET的视觉读取和基于体素的测试。©2023作者。Wiley Periodicals LLC代表国际帕金森病和运动障碍协会出版的《运动障碍》。

Automatic covariance pattern analysis outperforms visual reading of 18F-fluorodeoxyglucose-positron emission tomography (FDG-PET) in variant progressive supranuclear palsy

Background

To date, studies on positron emission tomography (PET) with ¹⁸F-fluorodeoxyglucose (FDG) in progressive supranuclear palsy (PSP) usually included PSP cohorts overrepresenting patients with Richardson's syndrome (PSP-RS).

Objectives

To evaluate FDG-PET in a patient sample representing the broad phenotypic PSP spectrum typically encountered in routine clinical practice.

Methods

This retrospective, multicenter study included 41 PSP patients, 21 (51%) with RS and 20 (49%) with non-RS variants of PSP (vPSP), and 46 age-matched healthy controls. Two state-of-the art methods for the interpretation of FDG-PET were compared: visual analysis supported by voxel-based statistical testing (five readers) and automatic covariance pattern analysis using a predefined PSP-related pattern.

Results

Sensitivity and specificity of the majority visual read for the detection of PSP in the whole cohort were 74% and 72%, respectively. The percentage of false-negative cases was 10% in the PSP-RS subsample and 43% in the vPSP subsample. Automatic covariance pattern analysis provided sensitivity and specificity of 93% and 83% in the whole cohort. The percentage of false-negative cases was 0% in the PSP-RS subsample and 15% in the vPSP subsample.

Conclusions

Visual interpretation of FDG-PET supported by voxel-based testing provides good accuracy for the detection of PSP-RS, but only fair sensitivity for vPSP. Automatic covariance pattern analysis outperforms visual interpretation in the detection of PSP-RS, provides clinically useful sensitivity for vPSP, and reduces the rate of false-positive findings. Thus, pattern expression analysis is clinically useful to complement visual reading and voxel-based testing of FDG-PET in suspected PSP. © 2023 The Authors.
