background and purpose : there has been no report in which preoperative evaluation of adc for prediction of post therapeutic outcome was presented. the aim of our study was to retrospectively evaluation the use of the apparent diffusion coefficient (adc) for the prediction of malignancy and the outcome of malignant astrocytic tumors. methods: we reviewed mri of 26 male and 14 female patients wi...

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...

Objectives: The purpose the study was to evaluate role of diffusion weighted magnetic resonance imaging (DW-MRI) in diagnosis benign and malignant breast lesions, calculate a cut-off apparent coefficient (ADC) value explore use relative ADC (r ADC) for improving sensitivity specificity MRI cancer. Methods: This retrospective based on cohort patients who underwent dynamic contrast enhanced (DCE)...

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...

OBJECTIVE To assess the feasibility and reliability of apparent diffusion coefficient (ADC) measurements of normal adrenal glands. MATERIALS AND METHODS This was a retrospective study involving 32 healthy subjects, divided into two groups: prepubertal (PreP, n = 12), aged from 2 months to 12.5 years (4 males; 8 females); and postpubertal (PostP, n = 20), aged from 11.9 to 61 years (5 males; 1...

This issue of Journal of Medical Radiation Sciences includes a study (Rundle-Thiele et al.) that investigates the correlation between magnetic resonance imaging (MRI)-based estimates of water mobility in glioblastoma tumours and expression of the prognostically important gene promoter methylguanine methyltransferase (MGMT). The authors address previous inconsistent reports regarding a correlati...
