Objective To observe the value of the corresponding solutions for MRI static magnetic field artifacts after analyzing their generating mechanism.Methods Different solutions was used to eliminate static magnetic field artifacts,such as improving inner and outer background,calibrating software and hardware,editing parameters,instructing patients,etc.in scanning patients or phantom with Siemens Impact 1.0T and GE Signa 1.5T MR by the use of SE or GRE sequences.Results Static magnetic field artifacts were controlled to different extent and the quality of the mass MR images were improved.Conclusion Most static magnetic field artifacts can be eliminated completely or reduced by using corresponding solutions,so more corrective information can be provided to clinic.

Dual source CT is a kind of 64 slices CT including two acquisition systems. It possesses such advantages as higher SNR of images,higher resolution of time,lower dose of radiation,bigger FOV of scanning,wider coverage of scanning and dual enrage subtraction imaging,etc. Weather these advantages could be brought into full play has great relationship with the preparations of dual source CT before its installation. The corresponding discussion is made in this text to see how to make preparations for dual source CT in different aspects such as room building,surrounding background,power supply,fire protection,radiation protection and periphery,etc.

Objective To investigate the feasibility and efficacy of tunica vaginalis flap cover in treatment of recurrent urethrocutaneous fistula (UCF).Methods We reviewed the clinical datas of 25 cases of UCF after urethroplasty of hypospadias from January 2011 to January 2015.The mean age of the patients was 6.2 years(range 1.6-14.0 years).All patients had undergone previous hypospadias repair and at least one previous failed attempt to close the urethrocutaneous fistulae.There were 5 cases of fistula in the coronary sulcus,6 cases of fistula in the penile body and 14 cases of fistula at the junction of penis and scrotum.The diameter of urethrocutaneous fistulae were 3-10 mm.Single fistula was present in all patients.16 cases had undergone UCF repair for two times, 9 cases had undergone UCF repair for more than two times.After closing the fistula with inverting running stitch, a tunica vaginalis flap was mobilized to cover the repair site through a subcutaneous tunnel and the skin closed.Results The mean follow-up time was 2.1 years(range 0.5-4 years).The overall success rate was 96％ (24/25).Penile cosmesis was excellent.There was no evidence of recurrent fistulas or urethral strictures.All parents reported a straight penis when erected, and one patient in whom there was leak from the fistula site because of local wound infection.No postoperative complication was encountered in the testis.The testis was of normal size and position, and the ultrasound findings were normal.Conclusions Repairment of recurrent urethrocutaneous fistulas with a tunica vaginalis flap could be effective regardless of fistula location.The technique is simple to improve the success rate of the repair of UCF effectively and reduce the occurrence of postoperative complications.

ObjectiveTo explore the diagnostic methods and surgery pattern at the first time of spontaneous perforation of congenital choledochal cyst.MethodsEleven cases(4 male,7 female) with spontaneous perforation of congenital choledochal cyst were 6 months to 5 years old,and their average course of disease were 4 days.Gustily abdominal distension,abdominal pain,crying and fever were present in all cases.Jaundice(7 cases) and emesis(5 cases) appeared.All cases were detected with physical sign of peritonitis by physical examination.Choledochal cysts were confirmed by CT or B ultrasound in 8 cases.All cases accepted abdominal paracentesis and biliary ascites was drawn.Three different operative procedures were performed:choledochocyst excision & Roux-Y choledocho-jejunostomy(2 cases),choledochotomy with T-tube drainage(3 cases),and cholecystostomy(6 cases).Nine children receiving external drainage operation accepted a second operation to rebuild biliary tract(choledochocyst excision & Roux-Y choledochoje-junostomy) after 3 to 6 months.ResultsAll cases had got satisfactory therapeutic efficacy without any grave complication such as fistula of anastomotic stoma,infection of biliary tract or obstruction of biliary tract.During operation,perforations were located in the juncture of choledochus and cystic duct in 5 children and were not found in the other 6 children.In the second operation,the cases receiving cholecystostomy had less peritoneal adhesion,anatomic structure changes,haemorrhage[(30-50) mL vs(100-200) mL] and operation time[(2.5-3.0) h vs(3.5-5.0) h] than those receiving choledochotomy with T-tube drainage,and did not appear inadequate drainage for cystic duct obstruction.ConclusionsFor children with more organ inflammatory edema and adherence and in a bad overall condition,the first-time operation of cholecystostomy is more reasonable.

Objective To explore the long-term efficacy of botulinum toxin type A injections on facial beauty and its long-term safety.Methods A total of 33 beauty-seekers with botulinum toxin type A treatment for more than five years were reviewed as observation group,using digital muscle palpation meter (Myoton PRO) for the determination of the orbicularis oculi muscle and masseter muscle tension (F),the muscle characteristic parameters,such as muscle hardness (S) using a homemade facial questionnaire test for satisfactory rate of beauty from both beauty-seekers and physicians.At sametime,33 normal adults that never accepted botulinum toxin injection with matched age and gender were collected as control group.The same-sex indicators were dtermined and compared with using statistic analysis t test.Results The pairwised parameters of the same sex and site were comparied between the two groups;average F and S values in the observation group were lower than those of the control group,but no statistically significant difference were observed between the two groups (P＞0.05);in the observation group,average appearance age was 7.3 years younger than the control group,and the facial shape improved significantly.Conclusions Long-term and repeated application of botulinum toxin A is able to remove crow's feet and decrease the masseter and so the injection is safe with high satisfaction to beauty-seekers.
