Abstract

Portal vein thrombosis (PVT) is usually diagnosed on contrast-enhanced CT, MRI or Doppler ultrasound. However, for patients with contraindications to intravenous contrast, its diagnosis is challenging. In these patients, PVT can be detected on unenhanced MRI using T2, T1 and diffusion-weighted imaging. These sequences may also help differentiate between bland PVT, portal pyemia and tumour thrombus. This case series aims to highlight the various appearances of PVT on unenhanced MRI.

摘要

门静脉血栓形成（PVT）通常通过增强CT、MRI或多普勒超声诊断。然而，对于有静脉造影剂禁忌证的患者，其诊断具有挑战性。在这些患者中，可使用T2、T1和扩散加权成像在平扫MRI上检测到PVT。这些序列也有助于鉴别单纯性PVT、门静脉脓毒症和肿瘤血栓。本病例系列旨在强调平扫MRI上PVT的各种表现。
