evaluation of sacral ratio as a prognostic factor in patients with anorectal malformations
correlation between sacral ratio and bowel function as well as fecal continence has been well documented in patients with anorectal malformations (arms). one hundred and twenty children with arms were investigated in this study. sacral ratio (sr) was measured from pelvic x-rays of patients. among these, 52 patients (43%) had no pelvic x-ray and were excluded from this study. sr was measured by ...
متن کاملAnorectal malformations with sacral bony abnormalities.
A range of anorectal malformations with sacral bony abnormalities was found in members from three generations of two kindreds. The anorectal anomaly was low in all but one of the patients. Partial sacral agenesis was the main bony defect in one family, and meningomyelocele and spina bifida occulta were noted in the second. The inheritance pattern in these kinships is autosomal dominant. This ma...
متن کاملmagnetic resonance imaging (mri)
basic physical principles of nuclear magnetic resonance imaging (n.m.r.i), a nonionizing medical imaging technique, are described. principles of nmri with other conventional imaging methods, ie, isotope scanning, ultrasonography and radiography have been compared. t1 and t2 and spin density (s.d.) factors and different image construction techniques based on their different combinations is discu...
متن کاملNon-uniformity of Clinical Head, Head and Neck, and Body Coils in Magnetic Resonance Imaging (MRI)
Introduction Signal intensity uniformity in a magnetic resonance (MR) image indicates how well the MR imaging (MRI) system represents an object. One of the major sources of image non-uniformity in high-field MRI scanners is inhomogeneity of radio-frequency coil. The aim of this study was to investigate non-uniformity in head, head and neck, and body coils and compare the obtained results to det...
