Dual-layer spectral detector computed tomography in distinguishing between bland and neoplastic portal vein thrombosis.

ABSTRACT:

Background

Differentiating bland from neoplastic portal vein thrombosis (PVT) is crucial for staging and treatment decisions in patients with suspected or confirmed liver malignancies. This study aimed to assess the diagnostic efficacy of the quantitative parameters of dual-layer spectral detector computed tomography (DLCT) in distinguishing between bland and neoplastic PVT.

Methods

This single-center prospective study included consecutive patients with identifiable PVT who underwent contrast-enhanced liver DLCT between April 2022 and August 2023. The reference standard was established based on imaging, patient history, and follow-up data. Quantitative parameters, including computed tomography (CT) attenuation values from conventional and virtual monoenergetic (40-90 keV) im
