Role of Apparent diffusion coefficient value in Diffusion Weighted imaging of MRI to assessment of radiotherapy efficiency in the patient with glioma tumor during treatment
Introduction: Glioma is the most common primary malignancy of cerebral neoplasms in adults, which in spite of therapeutic significant efforts, has a very poor prognosis. The current standard treatment of these patients generally includes surgery and radiotherapy or concurrent chemoradiotherapy with 6 courses of adjuvant use of temozolomide tabs. During these years, the nervous...
متن کاملSegmentation of Ischemic Lesion from Diffusion Weighted MRI and MR Apparent Diffusion Coefficient Maps
The utility of diffusion-weighted MRI (DWI) in the assessment of acute ischemic stroke is now becoming well-established. The quantitative evaluation of the lesion is however problematic because of the lower resolution of clinical images in the context of extreme emergency. We have developed a new segmentation technique to extract the ischemic areas from standard, clinical DWI image volumes. Tho...
متن کاملadditional value of diffusion-weighted imaging to evaluate prognostic factors of breast cancer: correlation with the apparent diffusion coefficient
results a low adc value was associated with lymph node metastasis (p < 0.01) and with high ki-67 protein levels (p = 0.03). there were no significant differences in the adc values among the histological grade (p = 0.48), molecular subtype (p = 0.51), tumor size (p = 0.46), and p53 protein level (p = 0.62). conclusion the pre-operative use of the 3.0 tesla dwi could provide information about the...
متن کاملrhabdomyosarcoma metastasis to the breast: appearance on diffusion-weighted imaging and apparent diffusion coefficient sequences
rhabdomyosarcoma is a common primary childhood malignancy that rarely metastasizes to the breast. we report a patient with a primary sinonasal rhabdomyosarcoma metastasizing to the breast, with no distant spread. we describe the imaging appearance of rhabdomyosarcoma on magnetic resonance imaging (mri), particularly on diffusion-weighted imaging (dwi) and apparent diffusion coefficient (adc) se...
متن کاملReproducibility of Apparent Diffusion Coefficient Measurements in Malignant Breast Masses
This study aimed to evaluate the reproducibility of apparent diffusion coefficient (ADC) measurements in malignant breast masses, and to determine the influence of mammographic parenchymal density on this reproducibility. Sixty-six patients with magnetic resonance findings of the mass were included. Two breast radiologists measured the ADC of the malignant breast mass and the same area on the c...
