Objective: A focal isolated lesion in the splenium of the corpus callosum(SCC) is a rare finding in MRI. The aim of the present study was to describe MR imaging findings of the SCC lesion and to analyze the relationship between this lesion and possible etiologic factors. Methods: Three patients with SCC lesion on MRI were reviewed. The imaging findings on MRI were analyzed. The clinical records and literature were also reviewed. Results: The first patient with influenza presented with mental symptom showed a lesion in the central portion of the splenium. After receiving antiviral medication, his neurological deficits completely recovered, and the diagnosis of virus-associated encephalitis was made. Two weeks later, the lesion completely disappeared. The second patient with epilepsy presented with signal abnormalities in the SCC in the context of presurgical epilepsy, the patient had received antiepileptic drugs for years. One week after operation for epilepsy, MR examination showed a clear reduction in lesion size. The last patient presented with abnormal neurological findings, and MRI showed an isolated SCC lesion and diffuse abnormal intensity in spinal cord. The diagnosis of acute disseminated encephalomyelitis(ADEM) was made and the recovery was complete in one month. Follow-up MR examinations showed complete disappearance of the SCC lesion. Conclusion: There is not a single condition or disease responsible for SCC lesion. These lesions are detected in a relatively large number of conditions with heterogeneous etiopathogenetic factors and a focal SCC lesion on MRI is a nonspecific finding.

DOI:
Objective: To explore the risk factors of hospital mortality in Stanford type A aortic dissection by analyzing its morphologic characteristics on CTA and thus try to design a rational treatment planning. Method: The imaging data of computed tomography angiography(CTA) from February 2011 and February 2013 in Changhai hospital in 47 patients with Stanford type A aortic dissection were analyzed retrospectively. All the patients were divided into death group(n=12) and control group(n=35), and all CTA images were reconstructed under Vitrea FX workstation, then measured and analyzed the morphological parameters related to hospital mortality by univariate and multivariate Logistic regression model and to analyse risk factors associated with hospital mortality of type A dissection. Result: There were two morphological parameters, including diameter at maximum(Wald χ2=5.839, P=0.016, OR=1.102) area level of aorta and number of involved branches(Wald χ2=4.594, P=0.032, OR=1.337) related with hospital mortality of type A dissection patients, both parameters were risk factors. Conclusion: The transverse diameter at maximum area level of type A dissection and the number of branching vessels involved by dissection are risk factors associated with hospital mortality. It is adovocated that patients with bigger length of aortic dissection and more branched vessels involved should be treated more actively.

DOI:
Objective: To assess left ventricular myocardial systolic dyssynchrony in patients with hypertrophic cardiomyopathy(HCM) by real-time three-dimensional echocardiography(RT3DE). Methods: Forty patients with HCM, 25 age and sex matched normal controls underwent examinations with 2D and full volume RT3DE. Ejection fraction was >0.55 in all subjects. According to with or without left ventricular outflow tract obstruction at rest, HCM patients were divided into 2 groups, non-obstructive HCM group and obstructive HCM group. With QLab 7.0 off-line software the 17 segmental volume-time curves were obtained. The difference(Dif) and standard deviation(SD) of the time to the point with minimal systolic volume(Tmsv) in 16, 12, and 6 segments were measured and adjusted by R-R interval(Tmsv Dif%, Tmsv SD%). Results: Compared with control group, the Tmsv 16-SD%, and there were no significant differences between non-obstructive and obstructive HCM group. The left ventricle volume-time curves of the HCM patients had disordered arrangement compared with the normal control. Conclusion: Systolic asynchrony is impaired in HCM patients with or without left ventricular outflow tract obstruction. The RT3DE is an useful method for detecting left ventricular dyssynchrony of HCM patients and provide additional value for understanding myocardial damage of HCM patients.

DOI:
Objective: To evaluate the accuracy of phase contrast(PC) MR in measuring the blood flow of aorta. Method: Eleven cases of blood flow in the beginning of aorta of the healthy volunteers were measured by using PC MR, and the stroke volume which was derived from the change of left ventricle within each cardiac cycle were measured by short axis cine MRI. The values of stroke volume by the two methods were analysed and compared. We compared the time that cost in scanning and post-processing of the two methods. Results: There were good consistency between net blood flow volume of aorta measured by using PC MR with that of left ventricle by short axis cine MRI(r=0.92). It took less time to scan and post-process imaging by using PC MR than short axis cine MRI. There was less inter-observer and intra-observer influence by using PC MR. Conclusion: PC MR is a noninvasive, safe, accurate method. It is a good way in research the blood flow dynamics of aorta by using PC MR, and can assess left ventricular systolic function.

DOI:
Objective: To evaluate functional CT in predicting the risks of interventional treatment for primary hepatic carcinoma. Materials and Methods: CT examination and laboratory tests were performed in 97 patients with primary hepatic carcinoma. Before undergoing interventional therapy, remnant hepatic volume measuring and portal perfusion scanning were performed. After interventional therapy, 29 patients showed acute hepatic failure(AHF group), and 68 patients had no hepatic failure(the non-AHF group). Peri-interventional imaging and experimental vairables were analyzed by analysis of variance and χ2 test respectively. The variables of significance(P＜0.05) were analyzed with stepwise logistic regression. Results: Ten variables including remnant hepatic volume per body surface area(RHVS), protal venous perfusion(PVP), hepatic blood flow(HBF), hepatic blood volume(HBV), diameter of catheter used for embolization, portal venous thrombosis, diameter of tumor, serum creatinine, thrombinogen activity, and Child-turcotte-pugh grading(CTP grading). The stepwise logistic regression analysis for the variables demonstrated that decreased RHVS, lowering of PVP, bigger diameter of the catheter and high level of serum creatinine were the independent risk factors of acute hepatic failure complicated to interventional therapy for primary hepatic carcinoma(P＜0.01). Conclusion: Hepatic functional reserve and risks of interventional therapy for primary hepatic carcinoma could be predicted and evaluated by funcional CT.

DOI:
Objective: To evaluate the diagnostic value of CT for synchronous colorectal carcinoma(SCRC). Methods: The clinico-pathologic and imaging results in 17 patients with SCRC were reviewed retrospectively. Results: Among the 17 patients with SCRC who underwent CT examination, 15 patients diagnosed as SCRC, 2 cases of SCRC happened in transverse colon and rectum were missed as transverse colon cancer and rectal cancer separately. Among the 16 cases who underwent colonoscopy examination, in 12 cases the colonoscopy arrived to the ileocecal region, and 11 cases were accurately diagnosed, 1 case was diagnosed as moderate dysplasia by preoperative pathology, in 4 cases there was incomplete colonoscopy due to intestinal stenosis caused by distal lesion so missed the proximal lesion. Conclusions: CT is an essential modality for diagnosing SCRC. Familiar with the imaging features of SCRC, strict training of doctor’s technique and awareness for the presence of SCRC can improve the accuracy of preoperative diagnosis.

DOI:
Objective: The imaging findings of CT, conventional MRI and fat saturation sequence in the lumbar articular joint degeneration were observed to further improve clinical importance. Methods: The imaging data of 538 patients with lumbar articular joint degeneration were restrospectively analysed. The results of CT, conventional MRI, and fat saturation sequence were analyzed by Chi-Square tests. Results: Fat saturation sequence was superior than CT and conventional MRI in terms of showing facet joint synovitis, MRI is better than CT in showing articular cartilage(P<0.05). There were obvious advantages for CT in observing bone destruction, vacuum sign, and secondary signs(P<0.05). But there was no significant difference in osteoarthritis among them(P>0.05). Conclusion: Conventional MRI and fat saturation sequence are the choice of technique for acute-inflammatory phase of disease, but CT is the choice for chronic phase or pre-operation.
