About Us | Services | Our Team Expert | Contact Us

Nuclear Medicine is a clinical specialty that uses radioactive materials specifically Radiopharmaceuticals in the diagnosis and treatment of various diseases in both adult and pediatric patients. The gamma camera and the computer interfaced to it are the primary instruments used. Together, they have served as the catalyst-responsible for enhancing the urique ability of Nuclear Medicine to provide functional information that is not possible with other anatomic imaging modalities.

Throughout the years, Nuclear Medicine has proven its worth and has gained acceptance in different clinical fields such as Endocrinology, Cardio-Pulmonary, Nephro-Urology, and Gastroenterology and Oncology.

We deliver the most rapid and accurate diagnosis in the specialty using high-quality radiopharmaceuticals.

We aim to provide the highest quality health care to all patients.

About Us


The year 2011 was a transition period for the unit with the much-anticipated transfer to the new NKTI Diagnostic Center with its state-of-the-art equipment.  The transfer began in the month of July and the unit started full operations with actual patients by the first week of August 2011.

Located in the ground floor of the Diagnostic Center, the Nuclear Medicine Division now boasts new imaging cameras namely:  Siemens Symbia Evo Excel and GE Discovery NM630 Gamma Cameras, acquired in 2019 and 2020, respectively, as well as Hologic Discovery A DXA Bone Densitometer. These top-of-the-line equipment serves as the unit’s workhorses in providing imaging and non-imaging diagnostic procedures in Nuclear Medicine and allied specialties.

The Siemens and GE gamma cameras provide superb image resolution with short imaging time due to its numerous cutting-edge technologies incorporated in both its hardware and computer.  It can image closer to the patient at a faster time without compromising image resolution whether planar, tomographic, or dynamic imaging.
