Parastomal hernia occurs frequently after the formation of a colostomy or ileostomy and it is the most common late stoma complication. Contents of parastomal hernia almost exclusively are limited to the mobile structures of the abdomen. Parastomal hernia including stomach is extremely rare. We describe a case of parastomal hernia containing stomach in a 65 year old woman who underwent rectal resection and left lower quadrant colostomy two years ago for rectal adenocarcinoma. The patient was presented to our emergency department with abdominal pain, vomiting and upper abdominal distension proceeding for 2 weeks. Abdominal CT revealed mild gastric dilatation associated with a parastomal hernia that contained the gastric corpus and antrum. The parastomal hernia was manually reduced. After 7 days, the patient fully recovered and was discharged. Parastomal hernia may contain stomach in patients presenting with obstructive symptoms. To the best of our knowledge, the current case has been published the ninth of such cases. Although rare, the present case is noteworthy in highlighting both the importance of being aware of this entity as well as radiologic confirmation to make correct diagnosis.","PeriodicalId":13333,"journal":{"name":"Imaging in Medicine","volume":"8 1","pages":"5-8"},"PeriodicalIF":0.0,"publicationDate":"2017-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89407459","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Crisp values are inadequate to model real situation due to imprecise information frequently used in decision making process. Various intuitive methods have been explored to understand the ambiguity and uncertainty of medical images to carry out segmentation task. Therefore, in this paper, an attempt has been made to segment the medical images using clustering method based on Intuitionistic fuzzy set. With the incorporation of spatial information into intuitionistic clustering named as Spatial Intuitionistic Fuzzy C Means (SIFCM), the object of interest is segmented more accurately and effectively. The benefits of incorporating spatial information is that it is a powerful method for noisy image segmentation and works for both single and multiple-feature data with spatial information as well as capable of reduction of noisy spots and spurious blobs. The performances of proposed methods are evaluated for real images. The results indicate that SIFCM is more effective, and noise tolerant as compared with the fuzzy c-means clustering.","PeriodicalId":13333,"journal":{"name":"Imaging in Medicine","volume":"47 1","pages":"95-101"},"PeriodicalIF":0.0,"publicationDate":"2017-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80802220","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We investigated the long-term transition of geometrical accuracy of a commercially available rigid and deformable image registration (RIR, DIR) software product, MIM Maestro, in livers of patients who underwent proton beam therapy (PBT). Methods: Image registration of pre-treatment and post-treatment CT was performed in 15 liver tumor patients who received PBT and follow up post-treatment CT examination was performed over time (2-7 times each, a total of 54 times). We performed RIR and DIR of pre-treatment CT and compared the post-treatment CT by calculating the similarity of whole liver (Dice similarity coefficient: DSC) and dislocation of metallic markers implanted close to the tumor (fiducial registration error). Results: In the plain CT, the DSC was bigger with RIR in 1 case and DIR in 53 cases (0.83 ± 0.07 vs. 0.92 ± 0.04), then consistently bigger with DIR in 14 patients. The fiducial registration error was smaller with RIR in 10 cases, DIR in 43 cases, and equal error in 1 case (11.8 ± 6.9 vs. 7.6 ± 9.7 mm), then consistently smaller with DIR in 10 patients. In the contrast-enhanced CT, the DSC was consistently bigger with DIR in all 15 patients, 54 cases in all (0.84 ± 0.06 vs. 0.92 ± 0.03). The fiducial registration error was smaller with RIR in 7 cases and DIR in 47 cases (11.0 ± 6.3 vs. 6.3 ± 7.3 mm), then consistently smaller with DIR in 12 patients. Conclusion: The DIR performance of MIM is therefore superior to that of RIR and its advantage is independent the term after PBT.","PeriodicalId":13333,"journal":{"name":"Imaging in Medicine","volume":"16 1","pages":"149-154"},"PeriodicalIF":0.0,"publicationDate":"2017-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86858641","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Intraoperative nerve injuries often cause permanent neurogenic untoward events such as functional disorders, palsy, pain and numbness. To avoid such accidents, we devised an intraoperative fluorescence-imaging of peripheral nerves as a contribution to navigation surgery. Myelin-targeting fluorescent agents; namely, amphotericin B and fluorescinisothyanate, were used as markers of nerves in this study since myelin was a main component of Schwann sheath in peripheral nerve. In in vitro, cultured Schwann cells were served as model of peripheral nerves. After treating Schwann cells with each fluorescent agent, we observed the fluorescence emitted in a dark room. Then, we carried out in vivo studies with rats following the results of in vitro data and assessed the clinical significance of our newly devised method. We could clearly observe specific florescence the Schwann cells radiated in in vitro and discriminated peripheral nerve fibres from surrounding tissues in in vivo. These results strongly suggested a clinical usefulness of intraoperative visualization of peripheral nerve fibres. Our novel method would promote intraoperative nerve- preservation.","PeriodicalId":13333,"journal":{"name":"Imaging in Medicine","volume":"1 1","pages":"143-148"},"PeriodicalIF":0.0,"publicationDate":"2017-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82058095","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
