The effect of fasting on gallbladder opacification during oral cholecystography: a controlled study in normal volunteers.

abstract：:The authors used a gantry tilt of 20 degrees in five patients to allow fine-needle aspiration biopsy of peripheral pulmonary lesions that were difficult to approach with a vertical alignment because of overlying ribs. This method allowed a direct approach to the lesion in all five cases, with the entire needle path vi...
