The diagnostic accuracy of CT-based "Banner cloud sign" for dural ossification in patients with thoracic ossification of the ligamentum flavum: a prospective, blinded, diagnostic accuracy study protocol.

ABSTRACT:

Background

Ossification of the ligamentum flavum (OLF) is the most common cause of thoracic spinal stenosis, which responds poorly to conservative treatment. Thus, surgery is the only effective treatment for OLF. The existence of dural ossification (DO) makes surgery challenging and increases the risk of intra-/post-operative complications. To date, several methods have been proposed to identify DO, but either the diagnostic accuracy is low or the feasibility is poor. Therefore, the aim of this study was to propose a new imaging sign (Banner cloud sign, BCs), evaluate the accuracy of BCs in the diagnosis of DO, and provide reliable evidence-based data for its application in clinical practice.

Methods

A prospective, blinded, diagnostic accuracy study will be conducted to asse
