Offering reportedly seamless integration into workflows for prenatal evaluations and real-time decision-making, the cloud-based Delivery Date AI software was trained on millions of ultrasound images from diverse pregnancies.

In a recent interview, Ashesh Jani, M.D., discussed pertinent findings in two post-hoc studies from the SPOTLIGHT trial that examined the efficacy of 18F-flotufolastat PET/CT for detecting biochemical recurrence and bone metastases in patients with prostate cancer.

Full approval of PNT2003, a radioequivalent of Lutathera (lutetium Lu 177 dotatate), is subject to a 30-month stay — triggered by a Hatch-Waxman patent litigation — that is reportedly set to expire in June 2026.
