摘要

磁共振作为疾病诊断和监测的关键成像方式不断发展和进步。硬件和软件的进步继续推动这种模式到诊断成像领域的前沿。新一代磁共振造影剂,特别是具有更好的弛豫性和稳定性(相对于提供的对比效果)的钆螯合物,已经出现,为该领域提供了进一步的推动。关注钆在体内的沉积,主要是较弱的钆螯合物(现在已经从市场上移除,至少在欧洲)仍然是临床医生心中的最前沿。这引起了人们对锰基造影剂可能发展的新兴趣。光子计数CT的发展及其临床应用使CT图像质量的进一步重大进步成为可能,同时也有可能降低辐射剂量。首先认识到在胸部、心脏和肌肉骨骼成像方面取得重大临床进展的可能性,现在也认识到其更广泛的影响-跨越所有器官系统。常规获取全光谱多能数据(没有时间或辐射剂量的损失)的效用现在也被认为是光子计数CT的另一个主要进步。人工智能现在被用于大多数成像平台和模式的后台,使得成像技术和图像质量的进一步进步成为可能,尽管这一领域还远未实现其全部潜力。最后,但并非最不重要的是,超声领域在可用性(随着非常低成本系统的发展)和可能的新一代微泡造影剂方面取得了进一步的重大进展。

Diagnostic and Technological Advances in Magnetic Resonance (Focusing on Imaging Technique and the Gadolinium-Based Contrast Media), Computed Tomography (Focusing on Photon Counting CT), and Ultrasound-State of the Art.

Magnetic resonance continues to evolve and advance as a critical imaging modality for disease diagnosis and monitoring. Hardware and software advances continue to propel this modality to the forefront of the field of diagnostic imaging. Next generation MR contrast media, specifically gadolinium chelates with improved relaxivity and stability (relative to the provided contrast effect), have emerged providing a further boost to the field. Concern regarding gadolinium deposition in the body with primarily the weaker gadolinium chelates (which have been now removed from the market, at least in Europe) continues to be at the forefront of clinicians' minds. This has driven renewed interest in possible development of manganese-based contrast media. The development of photon counting CT and its clinical introduction have made possible a further major advance in CT image quality, along with the potential for decreasing radiation dose. The possibility of major clinical advances in thoracic, cardiac, and musculoskeletal imaging were first recognized, with its broader impact - across all organ systems - now also recognized. The utility of routine acquisition (without penalty in time or radiation dose) of full spectral multi-energy data is now also being recognized as an additional major advance made possible by photon counting CT. Artificial intelligence is now being used in the background across most imaging platforms and modalities, making possible further advances in imaging technique and image quality, although this field is nowhere yet near to realizing its full potential. And last, but not least, the field of ultrasound is on the cusp of further major advances in availability (with development of very low-cost systems) and a possible new generation of microbubble contrast media.
