Neuroendocrine neoplasms (NENs) are a diverse group of tumors that express neuroendocrine markers and primarily affect the lungs and digestive system. The incidence of NENs has increased over time due to advancements in imaging and diagnostic techniques. Effective management of NENs requires a multidisciplinary approach, considering factors such as tumor location, grade, stage, symptoms, and imaging findings. Treatment strategies vary depending on the specific subtype of NEN. In this review, we will focus on treatment strategies and therapies including the information relevant to clinicians in order to undertake optimal management and treatment decisions, the implications of different therapies on imaging, and how to ascertain their possible complications and treatment effects.
神经内分泌肿瘤（NENs）是一类表达神经内分泌标记物的多种肿瘤，主要影响肺部和消化系统。随着影像学和诊断技术的进步，NENs 的发病率也在不断增加。有效治疗 NENs 需要采用多学科方法，考虑肿瘤位置、分级、分期、症状和成像结果等因素。治疗策略因 NEN 的具体亚型而异。在本综述中，我们将重点讨论治疗策略和疗法，包括临床医生做出最佳管理和治疗决策的相关信息、不同疗法对影像学的影响以及如何确定其可能的并发症和治疗效果。

Conventional imaging protocols, including sagittal T1-weighted imaging (T1WI) and water-only T2-weighted imaging (T2WI), are time consuming when screening for spinal metastases with vertebral compression fractures (VCFs). In this study, we aimed to assess the accuracy of using only the Dixon T2-weighted sequence in the diagnosis of spinal metastases with VCFs to determine its suitability as a simplified protocol for this task.

This study reviews the spectrum of imaging findings and complications after transarterial chemoembolization (TACE) for the treatment of primary liver tumors (hepatocellular carcinoma, cholangiocarcinoma) and liver metastases. The review encompasses a spectrum of imaging criteria for assessing treatment response, including the modified Response Evaluation Criteria in Solid Tumors guidelines, tumor enhancement, and apparent diffusion coefficient alterations.We discuss the expected posttreatment changes and imaging responses to TACE, describing favorable and poor responses. Moreover, we present cases that demonstrate potential complications post-TACE, including biloma formation, acute cholecystitis, abscesses, duodenal perforation, arterial injury, and nontarget embolization. Each complication is described in detail, considering its causes, risk factors, clinical presentation, and imaging characteristics.To illustrate these findings, a series of clinical cases is presented, featuring diverse imaging modalities including computed tomography, magnetic resonance imaging, and digital subtraction angiography.

Accurate quantification of liver iron concentration (LIC) can be achieved via magnetic resonance imaging (MRI). Maps of liver T2*/R2* are provided by commercially available, vendor-provided, 3-dimensional (3D) multiecho Dixon sequences and allow automated, inline postprocessing, which removes the need for manual curve fitting associated with conventional 2-dimensional (2D) gradient echo (GRE)-based postprocessing. The main goal of our study was to investigate the relationship among LIC estimates generated by 3D multiecho Dixon sequence to values generated by 2D GRE-based R2* relaxometry as the reference standard.
肝脏铁浓度（LIC）的精确量化可通过磁共振成像（MRI）实现。肝脏T2*/R2*图由市场上销售的、供应商提供的三维（3D）多回波迪克森序列提供，可自动进行在线后处理，无需进行基于传统二维（2D）梯度回波（GRE）的人工曲线拟合。我们研究的主要目的是探讨三维多回波 Dixon 序列生成的 LIC 估计值与作为参考标准的基于二维 GRE 的 R2* 弛豫测量法生成的值之间的关系。
