A case of strangulated bowel obstruction in which transabdominal ultrasound was useful for preoperative diagnosis.

A 74-year-old man presented to the emergency department with the chief complaint of abdominal pain. A computed tomography scan showed paralytic ileus. An ileostomy tube was placed, but the symptoms of bowel obstruction did not improve.

Feasibility, safety, and efficacy of artificial carbon dioxide pneumothorax for computed tomography fluoroscopy-guided percutaneous radiofrequency ablation of hepatocellular carcinoma.

Purpose: To retrospectively assess the feasibility, safety, and efficacy of artificial carbon dioxide (CO) pneumothorax for computed tomography (CT) fluoroscopy-guided percutaneous radiofrequency (RF) ablation of hepatocellular carcinoma (HCC).

Materials And Methods: This study included 26 sessions of 24 patients in whom the creation of artificial CO pneumothorax was attempted to avoid the transpulmonary route during CT fluoroscopy-guided percutaneous RF ablation of HCC between April 2011 and December 2017. In these 26 sessions, 29 HCCs (mean tumor diameter: 12 mm, range: 6-22 mm) were treated.

Temperature imaging of water in a microchannel using thermal sensitivity of near-infrared absorption.

This paper presents a remote and preparation-free method of temperature imaging of aqueous solutions in microchannels of microfluidic chips. The principle of this method is based on the temperature dependency of the near-infrared (NIR) absorption band (ν(2) + ν(3) band) of water. Temperature images were constructed from absorbances in a narrow wavelength range including 1908 nm, the most sensitive to temperature in the band, measured by using an NIR camera and an optical narrow-bandpass filter.
