The spinal vacuum phenomenon: evaluation by gradient echo MR imaging.

abstract：OBJECTIVE:The prevalence and features of the thyroid pyramidal lobe (TPL) on computed tomography (CT) have been reported, but no ultrasound (US) study has been found. The purposes of the current study were to assess the sonographic prevalence and features of TPLs and to compare the US and CT parameters of TPLs. METHOD...
