Interest of diffusion-weighted echo-planar MR imaging and apparent diffusion coefficient mapping in gynecological malignancies: a review.
Magnetic resonance imaging (MRI) remains the standard modality for the local staging of gynecological malignancies but it has several limitations, particularly for lymph node staging or evaluating peritoneal carcinomatosis. Consequently, there has been a growing interest in functional imaging modalities. Based on molecular diffusion, diffusion-weighted imaging (DWI) is a unique, noninvasive mod...
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 کاملRole 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 کاملSources of functional apparent diffusion coefficient changes investigated by diffusion-weighted spin-echo fMRI.
The mechanism behind previously observed changes in the apparent diffusion coefficient (ADC) during brain activation is not well understood. Therefore, we investigated the signal source and spatial specificity of functional magnetic resonance imaging (fMRI) ADC changes systematically in the visual cortex of cats using diffusion-weighted (DW) spin-echo (SE) fMRI with b-values of 2, 200, and 800 ...
متن کاملFunctional changes of apparent diffusion coefficient during visual stimulation investigated by diffusion-weighted gradient-echo fMRI
The signal source of apparent diffusion coefficient (ADC) changes induced by neural activity is not fully understood. To examine this issue, ADC-fMRI in response to a visual stimulus was obtained in isoflurane-anesthetized cats at 9.4 T. A gradient-echo technique was used for minimizing the coupling between diffusion and background field gradients, which was experimentally confirmed. In the sma...
