新冠疫情的影響
由於封鎖措施以及擇期和非緊急影像檢查的延遲,新冠疫情對PET掃描市場造成了負面影響。包括PET掃描在內的核子醫學服務在2020年經歷了檢查數量的下降。然而,自2021年以來,診斷服務的恢復和患者預後的改善推動了市場的復甦。 PET影像在腫瘤學和神經病學領域日益增長的重要性將使市場重獲動力,並在預測期內保持穩定成長。
市場趨勢
混合影像系統日益普及
影響PET掃描市場的關鍵趨勢之一是混合影像系統(例如PET/CT和PET/MRI)的日益普及。這些系統結合了功能性影像和解剖成像,以提高診斷準確性、治療計劃制定和疾病監測。 歐洲核子醫學協會 (EANM) 於 2023 年發布的指南進一步支持將 PET/MRI 整合到常規臨床實踐中。
放射性示蹤劑研發與人工智慧整合的進展
放射性追蹤劑研發的持續進展正在改善癌症、神經系統疾病和心血管疾病的檢測和監測。此外,人工智慧 (AI) 和機器學習的整合正在增強影像重建、縮短掃描時間並提高工作流程效率,從而提高醫療機構對 PET 掃描的採用率。
市場成長驅動因素
慢性病發生率上升
癌症、神經系統疾病和心血管疾病發生率的上升是推動 PET 檢測需求的主要驅動因素。 PET 影像在早期檢測、分期和治療追蹤中發揮關鍵作用。根據世界衛生組織估計,帕金森氏症和阿茲海默症等神經系統疾病在全球範圍內持續增加,推動了對先進診斷影像檢測的需求。
對早期精準診斷的需求日益增長
政府措施、不斷增長的醫療保健支出以及對診斷基礎設施的投資正在推動對早期精準診斷工具的需求。 PET掃描具有高靈敏度和特異性,使其成為現代診斷流程的重要組成部分。
限制因子
儘管成長前景良好,但市場仍面臨諸多挑戰,例如設備和檢測成本高昂、放射性藥物供應有限以及新興國家保險覆蓋範圍有限。此外,能夠操作先進影像診斷系統的熟練專業人員短缺仍然是一個主要限制因素,尤其是在發展中地區。
依適應症劃分
腫瘤學領域預計將在2026年佔66.93%的市場佔有率,這主要得益於全球癌症負擔的加重以及PET掃描在診斷和治療隨訪中日益廣泛的應用。 由於神經系統疾病和心血管疾病的盛行率不斷上升,神經病學和心臟病學領域也佔了相當大的佔有率。
依資金來源劃分
到2026年,公共醫療保險領域佔了84.26%的顯著佔有率,這主要得益於政府對醫療保健的投入以及已開發國家擴大PET成像程序的報銷範圍。
依服務提供者劃分
到2026年,醫院以65.34%的市佔率領先。這得歸功於先進的基礎設施、龐大的患者數量以及混合成像系統的普及。 由於獨立影像設施的增加,診斷中心預計將保持穩定成長。

主要公司包括 RadNet, Inc.、Sonic Healthcare Limited、Akumin Inc.、Alliance Medical Limited、Apex Radiology、InHealth Group 和 Novant Health。 策略聯盟、人工智慧整合以及影像診斷網路擴展將繼續是關鍵的競爭策略。
The global positron emission tomography (PET) scan market is witnessing steady growth due to the increasing burden of chronic diseases, rising demand for early and accurate diagnostics, and continuous advancements in imaging technologies. Positron emission tomography is a nuclear imaging technique that enables visualization of metabolic and physiological activities within the body, making it highly valuable for oncology, cardiology, and neurology applications.
In 2025, the global PET scan market size was valued at USD 18.71 billion. The market is projected to grow from USD 19.46 billion in 2026 to USD 29.67 billion by 2034, registering a CAGR of 5.41% during the forecast period (2026-2034). North America dominated the global market with a 52.38% market share in 2025, supported by advanced healthcare infrastructure, strong reimbursement frameworks, and widespread adoption of hybrid imaging systems.
COVID-19 Impact
The COVID-19 pandemic had a negative impact on the PET scan market due to lockdowns and the postponement of elective and non-emergency imaging procedures. Nuclear medicine services, including PET scans, experienced a decline in procedure volumes during 2020. However, since 2021, the resumption of diagnostic services and improved patient outcomes have supported market recovery. The growing importance of PET imaging in oncology and neurology has enabled the market to regain momentum and maintain steady growth during the forecast period.
