Objective: It was aimed to create special phantom to be used for benchmarking the
lesion detectability of planar, SPECT and SPECT / CT systems by computing the corresponding
contrast (C) and contrast / noise ratio (CNR) of the lesions with different
activity concentrations.
Method: In the study,
the phantom was equiped with with four lesions filled with radioiodine (131I).
The phantom’s planar images were acquired by two different gamma cameras with
small field of view (SFOV) and large field of view (LFOV). Tomographic images
were obtained from SPECT and SPECT / CT scans. Contrast (C) and
contrast-to-noise ratio (CNR) were calculated by delineating areas of interest
(ROI) over the tubes and background with different activity concentrations in
the phantom.
Results: As the camera’s
field of view increased, the related contrast and CNR values increased
partially. Contrast and CNR values of SPECT and SPECT / CT images were
significantly higher than planer images.
Conclusions:
It was found that the superior lesion
detectability might be achieved by SPECT or SPECT / CT (AC) imaging techniques.
