This study investigated the repeatability and assessed
the radiologic quality of reduced field of view
diffusion weighted imaging (rFOV DWI) in thyroid glands
of healthy human volunteers. Repetitive DWI scans were
performed on each subject within the same scan exam and
across scan exams. Image qualities were scored and
apparent diffusion coefficient (ADC) values were
calculated on the lobes of thyroid glands and followed
by reproducibility investigation. The study demonstrated
that rFOV DWI had significantly improved image quality
but lower ADC values and lesser repeatability value of
ADC compared to the conventional DWI techniques in the
region of thyroid glands.
