Article Synopsis
- * A study reviewed 46 patients who had completion cholecystectomy after subtotal cholecystectomy, finding that remnant cholecystitis was the main reason for reoperation in 80.4% of cases, with some encountering complications like bile leaks and pancreatitis.
- * The procedure is generally safe and effective, with a high rate of symptom resolution (95.6%), although it can be technically challenging, with a small percentage needing conversion to open surgery.
Objectives: The aim of this study was to determine the diagnostic accuracy of grating-based phase-contrast computed tomography (gb-PCCT) to classify and quantify coronary vessel characteristics in comparison with optical coherence tomography (OCT) and histopathology in an ex vivo setting.
Materials And Methods: After excision from 5 heart specimens, 15 human coronary arteries underwent gb-PCCT examination using an experimental imaging setup consisting of a rotating molybdenum anode x-ray tube, a Talbot-Lau grating interferometer, and a single photon counting detector. Subsequently, all vessels were imaged by OCT and histopathologically processed.
Objectives: To evaluate the potential of grating-based phase-contrast computed-tomography (gb-PCCT) to classify human carotid and coronary atherosclerotic plaques according to modified American Heart Association (AHA) criteria.
Methods: Experiments were carried out at a laboratory-based set-up consisting of X-ray tube (40 kVp), grating-interferometer and detector. Eighteen human carotid and coronary artery specimens were examined.
Objective: The objective of this study was to assess the potential of grating-based phase-contrast computed tomography (gb-PCCT) for the detection and characterization of human coronary artery disease in an experimental ex vivo validation study.
Materials And Methods: The study was approved by the institutional review board, and informed consent was obtained from all patients. Specimens were examined using a conventional low-coherence x-ray tube (40 kV) and a Talbot-Lau grating interferometer.
Background: Traumatic rupture of the thyroid gland is rare. A common approach does not exist. Surgical and nonsurgical management have been advocated.
