ABSTRACT
Objective To observe the value of MRI in evaluation on the morphology and function of iliococcygeal muscles in fertile and nulliparous women.Methods Totally 50 healthy fertile women (fertile group,further divided into cesarean section subgroup and spontaneous delivery subgroup according to the mode of delivery) and 17 nulliparous healthy women (nulliparous group) underwent MR scanning in both natural and increased abdominal pressure state.Iliococcygeus thickness (ICT),coronal iliococcygeal angle (cICA) and sagittal iliococcygeal angle (sICA) of different states were measured and compared between the groups.Results In the natural state,the right and bilateral average sICA in the fertile group were larger than those in nulliparous group (both P＜0.05),while no statistical difference of ICT,right,left and bilateral average cICA and left sICA were found between two groups (all P＞0.05);the bilateral average sICA in spontaneous delivery subgroup was larger than that in cesarean section subgroup (P＜0.05).In increased abdominal pressure state,left,right sICA and bilateral average sICA in fertile group were larger than those in nulliparous group (all P＜0.05),while there was no statistical difference of ICT and cICA between two groups (all P＞0.05);no statistical difference of ICT,cICA nor sICA was found between spontaneous delivery subgroup and cesarean section subgroup (all P＞0.05).Conclusion MRI can accurately evaluate morphological and functional changes of iliococcygeal muscle in females.
ABSTRACT
Objective To evaluate the diagnostic value of MSCT in small bowel obstruction and related complications caused by diverticulitis.Methods Clinical data and CT findings of 13 patients with diverticulitis and related complications were reviewed.The imaging findings of diverticulitis were calculated and compared with those in other 20 cases without intestinal obstruction.Results Among the 1 3 cases with diverticulitis,8 occurred in the j ej unum and other 5 in ileum.CT revealed the diverticulitis in all patients as a predominantly cylindrical expansion in communication with the adjacent small bowel.CT showed intraluminal intestinal contents and little air bubbles in 3 cases with simple diverticulitis,thickening of the appendix lumen in 2 cases with perforated diverticulitis, and annular high-density in lumen in 2 cases with diverticulitis and bezoar.CT also showed diverticulitis with volvulus in 6 cases as mesenteric swirling.The average thickness of diverticula were (3.06±0.31)mm,and the average volume of diverticula were (98.98±38.59)cm3 , exhibting statistically significant differences between diverticulitis and control groups (P value were 0.000 and 0.000).Conclusion MSCT is helpful for the diagnosis of small bowel obstruction and related complications caused by diverticulitis.
