Nuclear medicine procedures have carried out in the Clinical Center of Montenegro – Podgorica since
2006 by the dual-headed SPECT and Digital gamma camera NUCLINE Spirit DH-V. In the first six months of the
gamma camera use (from September 2006 to March 2007) examinations of skeleton, kidneys, thyroid and lung
were performed. For diagnostic skeletal imaging (102 patients) the radiopharmaceutical 99mTc-MDP is used, and
administered activities were in the range from 555 to 740 MBq. For thyroid imaging (203 patients) 99mTcpertechnetate
is used, and administered activities were in the range (37-111) MBq. Lung imaging is performed for
3 patients, using 99mTc-MAA and administered activities in the range (111-185) MBq. Renal imaging is carried out
for 72 patients: 42 dynamic studies of kidneys were performed with 99mTc-DTPA and administered activities from
207 to 282 MBq, and 30 static kidneys scintigraphies were performed using the radiopharmaceutical 99mTcDMSA.
6 patients in the last mentioned group were children with year of birth between 2000 and 2006, and
administered activities were from 16.6 to 55.5 MBq. In the same group, activities 28.5 MBq, 74.4 MBq and 120
MBq were administered to three patients with age between 6 and 18 years, and in the other cases, administered
activities to the patients (adults) were in the range (59.2 to 196) MBq. The administered activities presented here
are basis for further estimations of cumulated activity and absorbed dose to the various organs, which is useful for
comparison of the average dose to patient organs in various nuclear medicine procedures and calculation of
effective dose equivalent and total effective dose, significant for an estimation of potential risk due to the
radioactivity administered to a patient during nuclear medicine procedures. It is very important for procedures
optimization and improvement of the radiation protection.
