Aim: This prospective study reports the acceptance testing of the Symbia Intevo Bold SPECT/CT scanner (Siemens Healthineers), recently installed at SQCCCRC, University Medical City, Muscat, Oman, before its clinical implementation.
Materials and methods: The acceptance tests were performed using a Low Energy High Resolution (LEHR) collimator and Technetium-99m (Tc-99m) as the radioactive source, following the manufacturer’s protocols. The tests included physical inspection, peaking and tuning, intrinsic and extrinsic uniformity calibration, intrinsic energy resolution, and planar spatial resolution without scatter. Key performance parameters such as full-width at half-maximum (FWHM), system sensitivity, and count rate performance were evaluated.
Results: All critical acceptance tests, including intrinsic energy resolution, energy calibration (symmetric curve), and extrinsic uniformity with the LEHR collimator, were completed and met the required specifications. System sensitivity and count rate performance were within the expected ranges, confirming the system’s readiness for clinical use.
Conclusion: The Symbia Intevo Bold SPECT/CT system passed all performance tests successfully. The acceptance testing validated the system’s optimal performance following international standards, ensuring its suitability for clinical operations.

I, Muhammad Sarwar Khan, am serving as Editor on Archives of Biotechnology and Biomedicine (ABB). I submitted an editorial titled, 'Edible vaccines to combat Infectious Bursal Disease of poultry' for publication in ABB. After submitting the manuscript; the services rendered by the management and technical personnel to handle and process the manuscript were marvelous. Plagiarism report was shared with me with complements before reviewers' comments, All steps including article processing and service charges were well taken care of keeping in view the author's interest/preference. All together, it was an encouraging and wonderful experience working with ABB personnel.
