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 کاملDiagnostic value of apparent diffusion coefficient for the accurate assessment and differentiation of intracranial meningiomas
BACKGROUND Diffusion-weighted imaging (DWI) along with the calculation of apparent diffusion coefficient (ADC), is a novel, non-invasive, and reliable technique of choice for accurate assessment and for the treatment planning of different types of brain tumors. It is more advantageous in the distinction and differentiation of benign from malignant meningiomas on the basis of ADC values. PURPO...
متن کاملPotential Value of Apparent Diffusion Coefficient (ADC) in First-Line Treatment of Retinoblastoma
Background and Purposes: Assess the correlation between Apparent Diffusion Coefficient (ADC) values and prognostic parameters in retinoblastoma, including a possible contribution to prediction of response to intra-arterial chemotherapy (IAC). Materials and Methods: Conventional MR images and ADC-maps in 38 retinoblastoma patients (23 males, 15 females, mean age 26.8 months, 4 group B, 2 group C...
متن کاملOptimised diffusion-weighting for measurement of apparent diffusion coefficient (ADC) in human brain.
This work studies the effect of diffusion-weighting on the precision of measurements of the apparent diffusion coefficient (ADC, or D) by diffusion-weighted magnetic resonance imaging. The precision in the value of the ADC was described in terms of a diffusion-to-noise ratio (DNR) which was calculated as the signal-to-noise ratio in the resultant ADC. A theoretical analysis decomposed the DNR i...
متن کاملDifferentiation of benign and malignant breast lesions by apparent diffusion coefficient value in mass and non-mass lesions
Background: Diffusion-weighted imaging (DWI) is one of methods in evaluation of breast lesions. We aimed to investigate the apparent diffusion coefficient (ADC) values in breast tumors and their accuracy in differentiating benign versus malignant lesions. Methods: In this cross-sectional study, 72 patients with 88 breast lesions were investigated by 1.5-T breast MRI from 2015 to 2017 in Athari...
