a2z Radiology AI Raises $4.5M Seed Round to Scale Comprehensive CT Interpretation

a2z放射学AI筹集了450万美元的种子轮融资，以扩大全面的CT解读规模。

Funding from Khosla Ventures and SeaX Ventures follows FDA clearance and RSNA 2025 debut; company advances toward commercial deployment

Khosla Ventures 和 SeaX Ventures 在 FDA 批准和 RSNA 2025 首秀后提供资金支持；公司正朝着商业部署迈进。

BOSTON, December 9, 2025-- a2z Radiology AI, developer of AI systems for comprehensive medical imaging interpretation, today announced a $4.5M seed round with participation from Khosla Ventures and SeaX Ventures. The funding will accelerate commercial deployment of the company's FDA-cleared triage system and continued R&D toward broader imaging interpretation capabilities..

波士顿，2025年12月9日——a2z放射学AI公司，作为开发用于综合医学影像解读的AI系统的公司，今天宣布完成了450万美元的种子轮融资，Khosla Ventures和SeaX Ventures参与了投资。这笔资金将加速公司FDA批准的分诊系统的商业部署，并继续研发以实现更广泛的影像解读能力。

The investment comes on the heels of two milestones: FDA clearance for a2z-Unified-Triage, the first system to simultaneously triage seven urgent conditions on abdomen-pelvis CT scans in the U.S. market, and the company's debut at RSNA 2025, where it presented the first prospective study evaluating AI-assisted preliminary report drafting for abdomen-pelvis CT..

这项投资是在两个里程碑事件之后进行的：一是a2z-Unified-Triage获得FDA批准，这是美国市场上首个能够同时对腹部和骨盆CT扫描中的七种紧急情况进行分诊的系统；二是该公司在2025年北美放射学会（RSNA）年会上首次亮相，展示了首个评估人工智能辅助生成腹部和骨盆CT初步报告的前瞻性研究。

That study demonstrated that AI assistance reduced reporting time by 17.8%, increased radiologist confidence by 14.8%, and decreased mental demand by 22.4%—while improving detection of findings without increasing false positives. The results offer early evidence that comprehensive AI can meaningfully improve both accuracy and efficiency, addressing longstanding questions about the real-world value of radiology AI..

该研究表明，人工智能辅助使报告时间减少了17.8%，放射科医生的信心增加了14.8%，脑力负担减少了22.4%，同时提高了对结果的检测能力且没有增加假阳性。这些结果提供了早期证据，表明综合性人工智能可以显著提高准确性和效率，解决了长期以来关于放射学人工智能实际价值的问题。

'Radiology is one of the areas that will benefit the most from AI, ensuring no disease goes undetected,' said Vinod Khosla of Khosla Ventures. 'While others focus on single conditions, a2z is able to evaluate imaging for a broad range of issues, bringing us closer to the comprehensive capabilities of a real-life radiologist.'.

“放射学是将从人工智能中获益最多的领域之一，确保没有疾病被遗漏，”科斯拉创投的维诺德·科斯拉表示。“虽然其他公司专注于单一病症，a2z 能够评估广泛的影像问题，使我们更接近真实放射科医生的综合能力。”

'Radiology is central to modern medicine, but delays can slow down care when timely answers are essential,' said Dr. Kid Parchariyanon, Founder and Managing Partner of SeaX Ventures. 'a2z is meeting this challenge with technology that brings expert-level support directly to clinicians. We're proud to support a2z as they build the tools that make a meaningful difference for providers and patients worldwide.'.

“放射学是现代医学的核心，但当需要及时得到答案时，延误可能会减缓医疗服务的速度，”SeaX Ventures创始人兼管理合伙人基德·帕查亚南博士说道。“a2z通过技术迎接这一挑战，将专家级支持直接带给临床医生。我们很自豪支持a2z构建对全球医疗服务提供者和患者产生有意义影响的工具。”

With imaging demand outpacing the radiology workforce, clinicians face growing wait times for reads that guide critical decisions. Abdomen-pelvis CT alone accounts for over 20 million exams annually in the U.S.—the highest-volume CT category. a2z's approach differs from existing AI solutions that address single conditions: the company is building toward systems that can evaluate imaging comprehensively, the way radiologists actually work..

随着成像需求超过放射科医生的工作量，临床医生面临着越来越长的等待时间，而这些读片结果是指导关键决策的重要依据。仅腹部和盆腔CT每年在美国就占超过2000万次检查，是CT检查中数量最多的一类。a2z的方法不同于现有的针对单一疾病的AI解决方案：该公司正在构建能够全面评估影像的系统，就像放射科医生实际工作的方式一样。

'The response at RSNA validated what we've been building—AI that considers everything from A to Z in each study,' said Pranav Rajpurkar, PhD, co-founder of a2z Radiology AI and Associate Professor at Harvard Medical School. 'This funding lets us keep pushing on R&D while bringing our cleared technology to the care teams who need it.'.

“RSNA的反馈验证了我们一直在构建的东西——即在每项研究中从头到尾全面考虑的AI，”a2z放射学AI的联合创始人、哈佛医学院副教授Pranav Rajpurkar博士说道，“这笔资金让我们能够继续推进研发，同时将我们已获批的技术带给需要它的医疗团队。”

'We're building toward comprehensive interpretation of complex imaging studies at a level that simply hasn't existed before,' said Samir Rajpurkar, co-founder and CEO.

“我们正在构建对复杂影像学研究的全面解读，其水平是前所未有的，”联合创始人兼首席执行官萨米尔·拉杰普尔卡说。

The funding will support partnerships with health systems, continued product development, and commercial rollout in 2026.

这笔资金将支持与卫生系统的合作、持续的产品开发以及2026年的商业推广。
