Reproducibility of ultrasound measurement of pancreatic size with new advanced high-resolution dynamic image scanners.
The reproducibility of ultrasound measurements of the pancreas was investigated in 10 healthy volunteers. All subjects underwent three different evaluations, each consisting of three ultrasound examinations, at 8:00 after overnight fasting, at 12:00 after a solid, standard meal, and at 14:00. The longitudinal and anteroposterior (AP) diameters of the head, body, and tail, as well as the total areas of the gland, were measured in longitudinal and axial scans. Significant differences were observed in the head and body longitudinal diameters measured at 12:00 and in the tail AP diameter at 14:00. We conclude that ultrasonography of the pancreas should be performed in the morning with patients in the fasting state. In these conditions, the reliability of ultrasound measurements of the gland appears to be the highest.
