M.Sc. Nuclear Medicine (Quaid-e-Azam University, Islamabad)

Director CENUM, Lahore

Member Pakistan Society of Nuclear Medicine (PSNM)

Dr. Nasir Mahmood did his MBBS in 1985 from Quaid-e-Azam Medical College, Bahawalpur. He joined Pakistan Atomic Energy Commission (PAEC) as Medical Officer at PAEC HQrs Islamabad in 1987. He has received specialized training in the field of Nuclear Medicine from United Kingdom and Japan. He is Director of the Centre since July 2010.


Centre for Nuclear Medicine (CENUM), Lahore started functioning in early sixties (1963) under the name of Medical Radioisotope Centre. It was later on known as Atomic Energy Medical Centre and was renamed as Centre for Nuclear Medicine (CENUM), Lahore in the year 2001. Committed to the life saving concept and enhancement of healthcare standards in Pakistan, CENUM has been providing nuclear medicine services to the patients since its inception. More than forty thousand new patients are registered annually for various nuclear medicine procedures at the Centre.
CENUM continues to provide the best and yet affordable nuclear medicine services to its patients. This social mission and humanitarian legacy has been the driving force behind the Centre's efforts and achievements in Service, Teaching and Research, the "Three Pillars" of CENUM.
The Department of Diagnostic Nuclear Medicine at CENUM is equipped with the latest Single and Dual Head SPECT Gamma Cameras assisted by ultra-sensitive fast computers and are managed by highly trained & competent medical and technical experts. Our procedures commonly called Scintigraphic investigations or scan provide valuable functional-information (to a certain extent structural information as well) that can enable physicians / surgeons to make an early diagnosis. These tests are relatively safe, painless and are considered to be among the safest diagnostic tests available.
A specialized laboratory using RIA technique is available at CENUM for the determination of thyroid hormones, infertility hormones and tumor markers.
CENUM has the distinction of initiating the first ever Breast Care Clinic in PAEC medical centres. The Clinic is equipped with Metaltronica FLAT® SE Mammography Machine and Toshiba’s Nemio 20 Ultrasonography. A Colored Doppler Machine has been installed at the centre for detailed evaluation of the disease in breast. Patients suffering from all types of breast diseases are carefully examined.
Another milestone achievement of CENUM is the Thyroid Clinic where patients are diagnosed, managed and treated under the supervision of highly qualified and experienced physicians.
CENUM has been providing teaching and training facilities to postgraduate doctors from various specialties by organizing training and teaching programmes in the field of nuclear medicine. Students from various educational institutes come here for their research work. The Centre is also involved in research and training activities in collaboration with IAEA, Postgraduate Medical Institute Lahore, King Edward Medical University Lahore, Pakistan Institute of Engineering & Applied Sciences (PIEAS) Islamabad, University of the Punjab and University of Engineering & Technology, Lahore.
CENUM is constantly eyeing in the future and advancing. The possibilities that crop up for expansion are captured at the appropriate time. A most modern and state of the art dual head SPECT Gamma camera has been installed recently and is in operation to strengthen the Nuclear Medicine Department. A Bone Densitometer and a Digital X-ray machine are in operation thus broadening the spectrum of diagnostic facilities at the Centre.
 The key attribute to the centre success is its principles of meeting international standards of quality control. The strong believe in providing quality nuclear medicine service has earned CENUM continued and valuable trust.
