Local Research Productivity, Trends, and Collaboration Among Filipino Nuclear Medicine Physicians: A Bibliometric Analysis of the Philippine Journal of Nuclear Medicine

OBJECTIVE The Philippine Journal of Nuclear Medicine, the official publication and peer-reviewed journal of the Philippine Society of Nuclear Medicine, serves as a primary repository of research articles by Filipino nuclear medicine physicians. Despite rapid global developments in nuclear medicine, local research output remains underexplored. With ۲۰ volumes and multiple articles published, the PJNM best reflects the situation of nuclear medicine research in the country. This study analyzed and described local research productivity through a bibliometric analysis of PJNM from ۲۰۰۲ to ۲۰۲۵.METHODSFull-text research articles were retrieved from both physical and online sources. Eligible articles were classified by study type. Bibliographic data such as authorship and institutional affiliation were extracted. Descriptive statistics and bibliometric mapping using VOSviewer were employed to evaluate publication trends, collaboration networks, and keyword occurrences.RESULTSA total of ۱۳۴ full text articles were included. Publication output peaked during ۲۰۱۰-۲۰۱۲, followed by stable but modest productivity in subsequent years. Observational studies (۵۳%) comprised the majority of publications, followed by case report/series (۴۰%), and meta-analyses/systematic review (۷%). No experimental studies were published. JM Obaldo was the most prolific author (n = ۲۴), while GFL Goco demonstrated the strongest collaborative links (۳۷). St. Luke’s Medical Center-Quezon City produced the highest research output and linkages. Keyword mapping revealed seven thematic clusters, namely: bone imaging, cardiac and parathyroid scintigraphy, radioactive iodine therapy for thyroid cancer, pediatric scintigraphy, prostate cancer and theranostics, MPI SPECT image quality, and renal scintigraphy. The more recent articles focused on oncology, PET/CT, and theranostics. CONCLUSIONSPJNM reflects the growth and evolving focus of nuclear medicine research in the Philippines. While research output is diverse and increasingly aligned with international trends, there is a need to strengthen experimental and translational studies, foster broader collaborations, and achieve international indexing to enhance visibility and global impact.
