Objectives: To describe ultrasound findings and role of color Doppler in diagnosing of spontaneous isolated dissecting aneurysm of the superior mesenteric artery.
Methods: From 2015 – 2016, four cases were collected, male, age 48-60 years (mean age 53), diagnosis base on B-Mode and color Doppler which were confirmed by CT. All cases were in mild epigastric pain during scanning. There were three cases with acute onset epigastric pain sharply, relieve but not in recovery. In which the first case lasted one month, the second case lasted two months and the third case had acute epigastric pain for 2 days accompanied vomiting, dyspepsia and abdominal distension. Melena was noted in last case.
Results: The dissecting aneurysm happens at proximal part and extending to distal part, bigger than 10 mm in diameter, with intimal flap inside to split into true and false lumen. The flapping of intimal flap is not very clear.  There were two cases with false lumens contain fully thrombosis. The checkered appearance of color Doppler images represented in three cases. Two cases were endovascular stenting, conservative therapy for one, and last case unknown final result.
Conclusions: The checkered appearance of color Doppler images is typical pattern for diagnosing of dissecting aneurysm of superior mesenteric artery that can help in case of  not clear thin intimal flap.



2.  ACOUSTIC  RADIATION FORCE IMPULSE  IMAGING (ARFI)  of ULTRASOUND in ASSESSMENT  of PANCREAS DISORDERS

ABSTRACT:
PURPOSE :
 To evaluate pancreas elastic characters  using ARFI technique in normal individuals, diabetic patients and patients in mild acute pancreatitis.
 MATERIAL and METHODS:
Using SIEMENS S2000 with VTI and VTQ techniques to evaluate pancreatic tissue [head, body and tail with 3 times measurements  for  each part of pancreas] . There were total of  30 normal individuals  (age 20-40), and 34 diabetic patients suffering  from  diabetes  for 2-10 years enrolled in this study.  Patients were fasting 8 hours before ultrasound examination and in half sitting position. Statistic and data were treated by MedCalc software.
 RESULTS and DISCUSSIONS:
Elastic mean velocity ARFI of normal pancreas from normal individuals was V1= 0.96+/-0.16 m/s (range 0.6-1.19m/s), and more faster [harder] in diabetic patients, V1= 1.32+/-0.18 m/s.  There was significant statistic difference of elastic velocity in 2 groups (p under 0.0001). In diabetic patients, diabetic tissue  is getting fibrosis for a determined time [2 years, 5 years  and 10 years] , while cystic masses  and acute pancreatitis  getting harder . ARFI techniques reveals pancreatic tissue harder in old patients and  suffering from diabetes  for years.
 CONCLUSION:
Using ARFI techniques in routine daily clinical activities could help evaluating elastic properties of pancreas in diabetes and pancreatic disorders.
