Objective To evaluate the value of a CT ribs unfolding algorithm in the diagnosis of rib fracture. Methods Retrospective analysis of 180 patients who suffered chest trauma to do the chest or/and abdominal CT examination, and they also had the surgical or CT referral information. The images of these patients were postprocessed by software(Bone Reading software)and hand-drawn method(multi-point hand-painted CPR method). The rib fracture was observed and the time of reading was record. The diagnosis of fractures was confirmed by follow-up review or surgery. The fractures diagnosis sensitivity of the two post-treatment methods were measured, and the McNemar test was used to compare the difference between the software method and the hand-drawn method. Results Eight patients were excluded due to program failure, 172 cases were included in the study. Of the 172 patients, 63 patients suffered 259 fractures(178 ribs). The sensitivity of the software group was 91.7％(475/518), which was higher than that of the hand-painted group(86.3％, 447/518), the difference was statistically significant(P=0.005). The time of reading were (30.3 ± 3.3)and(173.2 ± 4.5)s, respectively, and the difference had statistically significant(P=0.001). Conclusion Compared to the traditional CPR method, the bone reading technique was used in patients with rib fractures during thoracic CT postprocessing can shorten the reading time and increase the sensitivity of the diagnosis.

Objective To investigate the therapeutic effect of the fourth ventricle tumors through lateral wall type of the transcerebellomedullary fissure approach under endoscope.Methods Clinical data of 14 cases with the fourth ventricle lesions were analyzed retrospectively.All the patients were treated by lateral wall type of the transcerebellomedullary fissure approach surgery.The endoscope was used if the lesions develop to the aqueduct and hard to be exposed.Both neurophysiological monitoring and intraoperative ultrasound were used regularly.Results Tumors were totally removed in 12 cases,subtotally in 1,and partially in 1.All the patients were diagnosed in postoperative histopathology,including 4 medulloblastoma,three epidermoid cyst,two ependymoma,two hemangioblastoma,one meningioma,one cavernous hemangioma and 1 astrocytoma.Hypopnea occurred immediate after operation in 1 patient.Ventilatory support was performed by Ventilator,and the respiration was restored 1 day later.Normal cerebrospinal fluid circulation was return in all cases.Neither aggravation of preoperative symptoms nor nuclei injury related complication had been found.The follow-up interval between 3 months to 28 months,one patient was dead with unexplained,and 1 medulloblastoma patient was relapse.Conclusion Lateral wall type of the transeerebellomedullary fissure approach,under endoscope,combined with the usage of neurophysiological monitoring and intraoperative ultrasound,can degrade the surgical related complications such as facial palsy and amblyacousia.

ObjectiveTo investigate the CT and MRI imaging characteristics of autoimmune pancreatitis and its clinical value.MethodsFourteen patients(13males, 1female, mean age 58.3 years) with autoimmune pancreatitis proved histopathologically or clinically were enrolled in the study.Clinical data was studied retrospectively.Among those patients,CT was performed on 12 cases and MR imaging was performed on 8 patients,6 patients underwent both CT and MR imaging.ResultsAll 14 patients had enlargement of the pancreas,which could be divided into three types including diffuse type ( n =7 ),focal type ( n =5 ) and mixed type ( n =2 ).On plain CT the pancreas was of isodensity ( n =5 ) or mild hypodensity ( n =7).In one case there was several small hypodensity cystic lesions within and around the pancreas that was rarely seen in other autoimmune pancreatitis cases.Pancreatic lesions as shown by MRI were all mildly hypointense on T1WI and mildly hyperintense on T2WI,all displayed lesions were detected as high-signal intensity areas on DWI. By medium contrast,autoimmune pancreatitis lesions demonstrated “ snow-like” heterogeneously decreased enhancement on artery phase of dynamic contrast enhanced imaging and then showed gradually delayed enhancement on portal venous phase and later phases.“Capsule-like” rim was present around the autoimmune pancreatitis lesions in 9 cases.Main pancreatic duct was irregular in shape in 4 cases and slightly dilated in 5 patients.Strictures of lower common bile duct and upper bile duct dilatation as well as thickening and enhancement of the bile duct wall were found in 9 cases.Peripheral vascular involvement was seen in 4 cases. Abdominal lymphadenopathy at hepatic portal was observed in 1 patient.Two cases showed tiny decreased enhancement lesions in the kidneys.Steroid therapy was given in 10 cases,all pancreatitis lesions ameliorated as showed by follow-up imaging examinations.ConclusionsAIP specific CT and MRI imaging findings are common in most patients which help establish the diagnosis and differential diagnosis of AIP.

Objective To study the imaging characteristics of the ligaments in craniocervical junction (CCJ), and to optimize the examination methods and scanning sequences of the ligaments in this region. Methods Two groups of 51 healthy volunteers in each were selected to undergo CT and MRI examination respectively. The CT and MRI features of the ligaments in CCJ were assessed. Two senior imaging doctors compared the results of showing the ligaments in CCJ by several MRI sequences, including T1 WI ,T2 WI, proton density weighted imaging (PDWI), T2 * WI and short time inversion recovery (STIR) ,and proton density fat saturate (PDFSAT). Standard normal rank transformation was done according to the primary data,and then analysis of variance of repeated measurement was applied. Results CT and MRI could both demonstrate the ligaments (except the anterior atlantooccipital membrane only seen on MRI) and their adjoins in CCJ, while MRI had more advantages than CT. The display ratio of the anterior atlantooccipital membrane was 100% (51/51) by MRI. The display ratio of the apical ligament was 29.4%(15/51) by CT and 43.1% (22/51) by MRI. The posterior atlantooccipital membrane-dura complex,tectorial ligament-dura complex, transverse ligament, and alar ligament could be demonstrated clearly by CT and MRI, the display ratio was 100% respectively (51/51). The results of PDWi scored by two doctors were both 5.0, there were no significant differences between them (F = 0.000, P > 0.05), which were significantly higher than T, WI (M = 3.0), T2Wi (M = 3.0), T2 * WI (M = 1.0), STIR (M = 1.0), and PDFSAT(M = 3.0)(P < 0.01). Conclusion MRI was superior to CT in demonstrating the ligaments in CCJ. PDWI was the optimal MRI sequence. Imaging research of normal ligamentous structures in CCJ could provide valuable diagnostic and therapeutic information for evaluating the ligamentous diseases.
