Lung tumors associated with obstructive pneumonitis: US studies.

abstract：:The authors describe the value of computed tomographic (CT) guidance for percutaneous gastrostomy (PG) or gastroenterostomy (PGE) in 22 patients with anatomic or pathologic difficulties precluding fluoroscopic guidance. Indications for PG or PGE were decompression for gastrointestinal obstruction (n = 15) or for feedi...
