The impact of pediatric-specific dose modulation curves on radiation dose and image quality in head computed tomography.

abstract：:Gallbladder volvulus in children is rare. Pre-operative diagnosis is considered difficult because of the nonspecific symptoms and inflammatory blood analysis findings. Sometimes diagnosis is confirmed at laparotomy. Many reports mention that the chief complaints of this disease are sudden and severe abdominal pain. We...
