A method for changing the tube current during helical scanning was applied to low-dose computed tomography (CT) in the lung. The changing method resulted in significant equalization of image noise in various lung sections compared with that at scanning with constant tube current. Detectability of nodules was equivalent between 60 mA and the changing method,(More)
Purpose: The aim of this study was to evaluate the effect of preoperative redistribution of gastric blood supply on the prevention of anastomotic leakage following surgical reconstruction of the esophagus. Methods: In 37 patients with esophageal carcinoma, transarterial embolization (TAE) of the left gastric, right gastric, and splenic arteries was(More)
The aim of this study was to examine the significance and problems of 2-[fluorine-18]-2-deoxy-d-glucose (FDG) positron emission tomography (PET) in diagnosing pancreatic cancer and mass-forming pancreatitis (MFP). PET, X-ray computed tomography (CT) and magnetic resonance (MR) imaging were performed in 15 patients with pancreatic cancer and nine patients(More)
Pulmonary infection with cavitation causes severe respiratory symptoms if the cavity has a communication with main bronchus, through which fluid flows out into trachea. In this report a young male with lung cancer invading an adjacent pre-existent fungus cavitary lesion is presented. Cancer invasion led to broncho-cavitary communication and caused massive(More)
