Detection of intraperitoneal free gas by ultrasound
Introduction: Patients with acute abdominal pain may have unsuspected pneumoperitoneum, and be investigated with ultrasound. Although not the primary imaging modality for this condition, ultrasound will usually demonstrate signs of free intraperitoneal or extra-luminal gas. Methods: Sonographic signs of pneumoperitoneum are described, along with the limitations and pitfalls of the technique. Th...
متن کاملextremal region detection guided by maxima of gradient magnitude
a problem of computer vision applications is to detect regions of interest under dif- ferent imaging conditions. the state-of-the-art maximally stable extremal regions (mser) detects affine covariant regions by applying all possible thresholds on the input image, and through three main steps including: 1) making a component tree of extremal regions’ evolution (enumeration), 2) obtaining region ...
Detection of low Intraperitoneal Air
Perforation of a hollow viscus is an acute abdominal drama and the accurate diagnosis highly depends on demonstration of free intrapritoneal air. The importance of adequate examination in the demonstration of ,tiny amount ()ff air is stressed and the value of an upright chest film when the horizontal beam is tangential to the top of the diaphragm is mentioned. Before standing for chest x-ray t...
متن کاملSpontaneous pneumoperitoneum and other nonsurgical causes of intraperitoneal free gas.
Intraperitoneal free gas seen radiologically as air under the diaphragm nearly always indicates a perforated abdominal viscus that requires surgical intervention. Rarely, however, the presence of a pneumoperitoneum may not indicate an intra-abdominal perforation and thus may not require laparotomy. Such a situation is termed spontaneous or nonsurgical pneumoperitoneum. In this review, we explor...
متن کاملMedical emergencies Spontaneous pneumoperitoneum and other nonsurgical causes of intraperitoneal free gas
NMA Williams, DFL Watkin Summary Intraperitoneal free gas seen radiologically as air under the diaphragm nearly always indicates a perforated abdominal viscus that requires surgical intervention. Rarely, however, the presence of a pneumoperitoneum may not indicate an intra-abdominal perforation and thus may not require laparotomy. Such a situation is termed spontaneous or nonsurgical pneumoperi...
