Meckel's diverticulum is the most frequent congenital malformation of the gastrointestinal tract, occurring in 2% of the general population. Meckel's diverticulum is usually asymptomatic and found incidentally. However, the lifetime risk of complications is 4-40%. In this essay, we describe the clinical and imaging findings in 12 cases of Meckel's diverticula with complications over a 5-year period, which were confirmed pathologically. The major complications of Meckel's diverticulum include gastrointestinal bleeding, bowel obstruction, perforation and inflammation. Small bowel follow-through (SBFT), computed tomography (CT) including CT enterography and RI scintigraphy can be used to show typical imaging features of Meckel's diverticulum and its complications. Knowledge of the clinical and radiologic findings of Meckel's diverticulum can aid in the early and accurate diagnosis of this anomaly and its complications.

A cortical defect with bright dotlike or curvilinear high-signal-intensity lesions on T2-weighted MRI may be an additional morphologic feature to increase the diagnostic performance of detecting anterior talofibular ligament injuries, including those with partial tears.

We analyzed the ratio of bronchial wall thickeness , the frequency of bronchial dilatation , the presence of emphysema , centrilobular nodule, and p 비 monary infiltration in two groups. In addition , we assessed HRCT findings of asthmatic patients for correlation with clinical findings and the p 비 monary function test Results: The ratio of bronchial wall thickness of 16 asthmatic subjects (0.48 ::t 0.08) and 16 control subjects(O 40 ::t 0.08) was significantly different in statistical analysis (p < 0.001). Bronchial dilatation was seen in 53(32 % ) of 165 bronchi in the asthmatic group and in 16(13 % ) of 119 bronchi in the control group, which was statistically significant (p
