Imaging

• MIT 研究人員發現，在精確條件下，混沌雷射光可以自我組織成高度聚焦的「鉛筆光束」（pencil beam），從而實現血腦屏障的快速 3D 成像。 • 該新方法的成像速度比現有技術快 25 倍，並能即時追蹤藥物進入腦細胞的過程。 • 這項突破讓科學家能高精度地觀察細胞中的蛋白質吸收情況，有望加速神經系統疾病的治療進程。

• Telix Pharmaceuticals resubmitted its New Drug Application to the U.S. FDA on March 16, 2026, for TLX101-Px (Pixclara®), a PET imaging agent targeting gliomas in adults and pediatrics. • The agent received Orphan Drug and Fast Track designations from the FDA due to its potential to address unmet needs in post-treatment glioma management, with 18F-FET PET already in international guidelines but no U.S.-approved equivalent. • Glioblastoma multiforme (GBM), the most common aggressive primary brain cancer, affects about 22,000 new U.S. cases yearly, with recurrence nearly universal and median survival of 12-15 months post-diagnosis.
