Objective: The aim of this study is to evaluate three techniques for calculating the sacroiliac joint (SIJ) index by bone scintigraphy in patients.
Materials and Methods: Patients (n:160) who did not exhibit abnormalities on bone scan were analyzed and were divided into 4 groups; 3-20 years, 21-40 years, 41-60 years, 61-86 years, respectively. Irregular and rectangular region of interest (ROI) were used for first and second methods, respectively. Horizontal rectangular ROI was selected for the last technique. The SIJ index was calculated by the following formula: SIJ count/sacrum count.
Results: There was no difference between the averages of all three methods according to right and left SIJ index (p>0.05). The averages of all SIJ values differed for three methods (p<0.05). The average of the first method values for all three situation was lower than the average of the other two method’s values (p<0.05). First technique had a lower mean for the right SIJ index than the other two techniques (p<0.05). The average of females was lower than males for all SIJ index values. The lowest average was detected at the age of 61 and above for three methods for both gender. All methods differed according to age (p<0.05). A relationship was detected between the age and all three index values of all techniques.
Conclusion: A threshold value for each method should be identified using with a fixed reference point for each age group taking into account gender.
