Prostate cancer (PCa) is the most common cancer afflicting men in USA. Multiparametric Magnetic Resonance (mp-MR) imaging is recently emerging as a powerful tool for PCa diagnosis. The development of CAD systems for its automatic processing and elaboration is growing but they can be affected by the variation of the imaging characteristics of PCa depending on its aggressiveness and location. The aim of this study is to characterize the homogeneity of a large set of data derived from mp-MR images, in order to assess the effect on the performances of a CAD system for PCa detection. Firstly, 15 semiquantitative and quantitative features were extracted from malignant and normal region of interest in 60 patients, who underwent mp-MR exam before prostatectomy. Then, we used a clustering procedure based on a Self-Organizing Map (SOM) for grouping patients with similar characteristics from the features point of view. Finally, we evaluated the impact of this partition on the malignant voxel detection by means of a classifier based on a set of SOMs trained and tested using only those patient belonging to the same cluster. We compared these results with those obtained using a unique classifier for all patients. From our analysis it emerged that the image partition in homogeneous groups can effectively improve the final detection performances.","PeriodicalId":221120,"journal":{"name":"2016 IEEE International Symposium on Medical Measurements and Applications (MeMeA)","volume":"187 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114743215","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}

The correct diagnosis of nontraumatic VCFs is therefore, fundamental for correct treatment. We aimed to classify VCFs using T1-weighted magnetic resonance images (MRI) of the lumbar spine acquired in the sagittal plane. Our study group comprised 63 patients (38 women and 25 men). From these patients 102 lumbar VCFs (53 benign and 49 malignant) and 89 normal vertebral bodies were manually segmented. The principal axis of each vertebral body region of interest was identified using moments. Statistical features of height and width measured perpendicular and parallel to the principal axis were computed. The k-nearest-neighbor method, a neural network with radial basis functions, and the naïve Bayes classifier were used with feature selection for classification. Areas under the receiver operating characteristic curve of 0.96 in the recognition of VCFs as compared with normal vertebral bodies and 0.73 for the classification of benign versus malignant VCFs were obtained. The proposed methods are promising for the recognition of VCFs, but additional features are needed to improve the classification of benign versus malignant VCFs.","PeriodicalId":221120,"journal":{"name":"2016 IEEE International Symposium on Medical Measurements and Applications (MeMeA)","volume":"2008 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128897457","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}

During swimming sessions the trainer is able of discriminating by sight large movement problems connected to the back pain, but an automatic intelligent system capable to assess the presence of movement problems could help the swimmer doing therapy by him/herself. This paper describes a possible easy-to-use solution, which is based on four small inertial systems to be installed on wrists and ankles in order to follow the movements of legs and arms. The inertial systems are composed of a commercial miniaturized Inertial Measurement Unit and by a Teensyduino board, which is able to store up to ten thousand inertial samples enabling recording the swimming for about four minutes. Angular velocity and acceleration recorded by the inertial systems are then transferred to a computer via an USB cable and processed to obtain an indication of the swimming asymmetry. The paper describes the design and realization of the acquisition units and the first results obtained by some patients during their therapy.","PeriodicalId":221120,"journal":{"name":"2016 IEEE International Symposium on Medical Measurements and Applications (MeMeA)","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121906387","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 evaluated whether it is possible to observe a variation of skin erythema, yellowness, pigmentation, color variance and xerosis induced by the season effect and the evaluated body site by using a new ultra-high definition videodermoscope. This videodermoscope provides images independent from the external lightening and reproducible. Videodermoscopy images were acquired at three body sites (photo-exposed forearm and face and photo-protected arm) of 149 elderly healthy volunteers. 79 subjects were evaluated in March and 70 subjects were evaluated in November. We found a difference in erythema, pigmentation, xerosis and yellowness in the two groups of subjects evaluated before and after the summer. As expected, erythema, pigmentation and xerosis increased and yellowness decreased after the summer. Some differences of these parameters were found in the three body sites independently from sun exposure. Videodermoscopy can provide quantitative data about both skin color and xerosis and in the future it could be used to evaluate different cosmetics and aesthetical procedures.","PeriodicalId":221120,"journal":{"name":"2016 IEEE International Symposium on Medical Measurements and Applications (MeMeA)","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123458993","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}
