The results were ranked from 1 to 5 (poor quality-high quality). Three nuclear medicine specialists blindly evaluated all image sets.
Acquisition, reconstruction and printing were performed according to the clinical routine in each centre. A three-dimensional high resolution brain phantom (Data Spectrum's 3D Hoffman Brain Phantom) was filled with a well-mixed solution of technetium-99m (110 MBq), water and detergent. Twelve laboratories participated in the study. The aim of the study was to evaluate the quality of routine brain perfusion single-photon emission tomography (SPET) images in Finnish nuclear medicine laboratories. Quality of brain perfusion single-photon emission tomography images: multicentre evaluation using an anatomically accurate three-dimensional phantom
this results: The investigation of small abnormalities strongly related to the operating conditions and deviation from best tuning state of the system Methods of Hoffman brain phantom was filled with a solution of Tc- 99 m (5 mCi) and water (1300 cc). In this research we made a comparison between normal and abnormal states of Hoffman brain phantom. To more meaningful ones based on performance of some tasks related to clinical application it is better to use from organs' phantoms, such as: brain, cardiac, etc. The above tests are simple physics measures. Each of the above standards has the following important orders: Physical inspection, Acceptance and Reference Testing, Periodic Q C tests (Daily, Weekly, Monthly, Quarterly, Annually).
There are the following standards for quality control in nuclear medicine: American Association of Physicists in Medicine, National Electrical Manufacturers Association, International Electromechanical Commission, International Atomic Energy Agency. The purpose of this investigation is using Hoffman brain phantom for quality assessment of brian images in SPECT system. International Nuclear Information System (INIS)
