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 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...
متن کاملSodium ion apparent diffusion coefficient in living rat brain.
The apparent diffusion coefficient (ADC) of Na(+) was determined in live rat brain. The brain extracellular-to-intracellular Na(+) content ratio is approximately 8:2, which is the inverse of that for water in these spaces. Consequently, the ADC of Na(+) is primarily affected by motion in the extracellular space, and Na(+) can be viewed as a reporter molecule for motion in that space. Likewise, ...
متن کاملBiexponential apparent diffusion coefficient parametrization in adult vs newborn brain.
The decay of brain water signal with b-factor in adult and newborn brains has been measured over an extended b-factor range. Measurements of the apparent diffusion coefficient (ADC) decay curves were made at 16 b-factors from 100 to 5000 s/mm(2) along three orthogonal directions using a line scan diffusion imaging (LSDI) sequence to acquire data from 0.09 ml voxels in a mid-brain axial slice. R...
متن کاملExploring the Possibility of Estimating Degree of Glioma Tumors by Measuring Apparent Diffusion Coefficient
Introduction: Most common glioma tumors are tumors of the central nervous system (CNS) which are the cause of about 40 to 50 percent of brain tumors. This type of cancer includes 2 to 3 percent of cancers in the world. Conventional MRI is powerless in the detection and differentiation of benign and malignant tumors. In this case, diffusion weighted imaging (DWI) can create cont...
