Method: Case report and review of the literature reporting other radiation-induced intra-medullary glioblastomas. Results: We report a case of glioblastoma of the conus, which subsequently metastasized to the brain, arising in a 45 years old man, nine years after treatment for Hodgkin's lymphoma, which had included the administration of 41 Gy to the brain and spinal cord. Conclusion: Despite a well-conducted treatment by several lines of chemotherapy, the pronostic of radiationinduced glioblastoma is poor especially since these patients often cannot benefit from a re-irradiation due to the maximum dose supported by the spinal cord. Implications of cancer survivors: Associations are now established between therapeutic exposures and specific complications but considerable inter-individual variability is observed for a given therapeutic exposure. In this context, identification of genetic susceptibilities for specific treatment-associated late effect is a very promising future approach. Improvement in our knowledge on genetic susceptibilities may help define more personalized primary therapies that weigh treatment efficacy with the risk of late complications.","PeriodicalId":90030,"journal":{"name":"OMICS journal of radiology","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2017-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.4172/2167-7964.1000257","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47615707","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}

This method uses the random diffusion motion of water molecule depending on physiological and anatomical characteristics of living organisms. Aim: To calculate the apparent diffusion coefficient and diffusion values in order to determine the degree in the glial tumors. Patients and methods: In the study, cases were selected among those who presented with a diagnosis of intracranial mass to Neurosurgery Department of Erciyes University, Medicine School. Overall, 20 patients were included to the study: 7 patients with Glioblastoma Multiforme (GBM), 4 patients with anaplastic astrocytoma (AA), 4 patients with diffuse astrocytoma, 3 patients with ependymoma and 2 patients with low-grade astrocytoma. The apparent diffusion coefficient (ADC) images were acquired from echo-planar diffusion-weighted images (DWIs). For each tumor, the mean ADC values and the mean diffusion value were measured at a large region of interest (ROI) defined within tumor and at symmetrical normal brain tissue. Statistical analyses were performed by using SPSS 15.0 Statistical Package Program. Results: We calculated mean ADC values (2.91 × 10-3 mm2/s, 0.69 × 10-3 mm2/s, 3.13 × 10-3 mm2/s, 2.41 × 10-3 mm2/s and 0.70 × 10-3 mm2/s) and mean diffusion values (0.11 × 10-3 mm2/s, 1.6 × 10-3 mm2/s, 0.10 × 10-3 mm2/s, 1.58 × 10-3 mm2/s, 0.90 × 10-3 mm2/s) for GBM, AA, diffuse astrocytoma, low degree astrocytoma and ependymoma, respectively. The diffusion value of normal brain was calculated to be 0.85 × 10-3 mm2/s. A P-value <0.05 was considered statistically significant. We estimated a significant difference between GBM and AA (p=0.001). Although there were marked differences among diffuse astrocytomas, low degree astrocytoma and ependymoma, the difference did not reach statistical significance. Conclusion: The mean ADC value, the mean diffusion value and intensity region may provide additional information in determining tumor degree in malignant glial tumors.","PeriodicalId":90030,"journal":{"name":"OMICS journal of radiology","volume":"2017 1","pages":"1-5"},"PeriodicalIF":0.0,"publicationDate":"2017-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.4172/2167-7964.1000256","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43456985","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}

Improved methods of diagnosis of cerebrovascular atherosclerosis would result in significant improvement in quality of life and major savings in health care costs. Imaging plays a critical role evaluating patients suspected of acute stroke. Magnetic Resonance Imaging (MRI's) significant advantages over DUS in carotids imaging can pay off its cost by means of improved patient outcome. Although DUS is frequently performed to evaluate carotid disease, there is nonuniformity in practice among laboratories. MRI can detect and quantify major compositional features of the carotid plaque and comprehensively evaluate its complications. A high level of agreement exists between high-resolution in vivo MRI, gross, and histological findings on the thickness and sites of potential rupture of the fibrous cap in advanced carotid artery atherosclerosis. MRI is capable of classifying and distinguishing different stages of atherosclerotic lesions. It can also examine the mechanisms of regression, progression, and endothelial dysfunction of the carotid plaque. Carotid MRI is a histologically validated, non-invasive imaging method that can track atherosclerotic disease progression and regression. It can quantitatively evaluate parameters associated with plaque morphology and composition. MRI is able to quantify high-grade carotid artery stenosis and occlusion with good accuracy and reproducibility and provides an opportunity to prospectively examine the relationship between plaque features and subsequent cerebrovascular events. The aim of this article is to examine the efficacy of MRI versus DUS in identifying vulnerable carotid lesions in the acute stroke patient that can account for stroke etiology or mechanism.","PeriodicalId":90030,"journal":{"name":"OMICS journal of radiology","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2017-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.4172/2167-7964.1000255","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42271330","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}

Median values of KAP showed a reduction over the eight years, although median values of T and I showed a slight increase during the same period.
