摘要

经动脉放射栓塞使用钇-90被广泛用于治疗不可切除的肝癌,通过直接向肿瘤输送辐射。而后处理成像通常依赖于单光子发射计算机断层扫描(SPECT)和SPECT/计算机断层扫描(CT),较低的信噪比和空间分辨率限制了其应用。PET/CT和PET/MR成像已被证明提供更有效的图像质量,产生更清晰的图像,用于准确的剂量量化和与治疗反应的相关性。基于pet的成像对于完善个性化剂量测定中的剂量-反应和剂量-毒性关系至关重要,尽管其有限的可用性挑战了其广泛使用。

Post-Y90 PET Dosimetry.

Transarterial radioembolization with yttrium-90 is widely used to treat unresectable liver cancer by delivering radiation directly to tumors. While post-treatment imaging generally relies on single-photon emission computed tomography (SPECT) and SPECT/computed tomography (CT), lower signal-to-noise ratio and spatial resolution limit its application. PET/CT and PET/MR imaging have proven to provide more effective image quality, yielding clearer images for accurate dose quantification and correlation with treatment response. PET-based imaging is crucial for refining dose-response and dose-toxicity relationships in personalized dosimetry, although its limited availability challenges its widespread use.
