Introduction: The liver fibrosis is caused by extracellular accumulation of cluster, glycos amino glycans and proteoglycans, which this extracellular accumulation may limit the penetration and molecular movement of water in the tissue, so the Diffusion weighted imaging(DWI) technique is due to the sensitivity to the movement and release of water molecules Can show this restrict...

Abstract BACKGROUND Stereotactic radiosurgery (SRS) is a cornerstone in the management of Breast Cancer Metastases to Brain (BCMB). While control rates are high following SRS, radiation necrosis rare but potentially devastating long-term toxicity. There clinical need for automated/semi-automated methods assess tumor response and optimize RT plans local with minimal Multiparametric MRI (mpMRI), ...

The purpose of this study is to develop a noninvasive quantitative imaging scheme to assess the functional microanatomy of dog brain using high resolution diffusion tensor imaging (DTI) at 7-Tesla (T) magnetic resonance imaging (MRI) scanner. Diffusion weighted images (DWIs) along 25 diffusion-encoding directions, combined with T2 weighted images, were acquired using the standard spin-echo diff...

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...

Abstract Background The purpose of this study was to investigate the diagnostic performance diffusion weight imaging (DWI), apparent coefficient (ADC) map, normalized ADC liver, and spleen compared dynamic contrast-enhanced MRI (DCE-MRI) in evaluation residual hepatocellular carcinoma (HCC) after radiofrequency ablation (RFA) using 3 T (T) magnetic resonance (MRI). Results A prospective perform...

background: gliomas are the most common primary neoplasms of the central nervous system. relative cerebral blood volume (rcbv) could estimate high-grade gliomas computed with dynamic susceptibility contrast mr imaging which it is artificially lowered by contrast extravasation through a disrupted blood-brain barrier. objectives: our intent was to clarify the usefulness of diffusion-weighted magn...

Background: The diffusion-weighted imaging (DWI) with apparent diffusion coefficient (ADC) map and the dynamic contrast-enhanced magnetic resonance (DCE-MRI) constitute functional MRI technique many oncological applications as it can define tissue microstructure characterize post-treatment changes from a recurrent tumor in treated head neck squamous cell carcinoma (HNSCC). Objective: To evaluat...

conclusions adc valuecould be a prognostic factor to monitor the response to therapy for patients with cervical cancer. the addition of dw-mri to the conventional mri protocolsconsiderably improved the diagnostic ability of mr imaging method for tumor evaluations. results studies had shown thatthe mean adc value of cervical carcinoma (1.110 ± 0.175 × 10-3 mm2/s)is significantly lower than that ...

The purpose of this study was to evaluate the capability and the reliability of diffusion-weighted MRI in the evaluation of normal kidney and different renal lesions. 39 patients (10 normal volunteers and 29 patients with known renal lesions) underwent MRI of the kidneys by using a 1.5 T superconducting magnet. Axial fat suppressed turbo spin echo (TSE) T(2) and coronal fast field echo (FFE) T(...

We present the procedure for designing a high speed and low power all-optical analog to digital converter (AO-ADC), by integrating InGaAsP semiconductor optical amplifier (SOA) with InP based photonic crystal (PhC) drop filters. The self-phase modulation in the SOA can shift the frequency of the Gaussian input pulse. The two output PhC based drop filters are designed to appropriately code the f...
