WebDWI is an MRI technique that is extremely sensitive for the detection of cytotoxic edema. It is highly specific and sensitive (> 95% for both) for the detection of acute ischemic infarcts and can differentiate acute from chronic infarctions. It has high signal-to-noise ratio and excellent interrater reliability. WebDWI is an imaging modality that combines T2 images with the diffusion of water. With DWI scans, ischaemia can be visualised within minutes of it occurring (Figure 5). This is because DWI has a high sensitivity for water diffusion, thereby detecting the physiological changes that happen immediately after a stroke.

Webhigh signal on DWI were collected. For each lesion, two radiologists independently measured the ADC values and evalu-ated the DWI morphological characteristics. The dierences of the quantitative and qualitative MRI features determined by the readers were assessed. The ADC values of the malignant and benign liver lesions were compared. WebJan 1, 2003 · However, high signal intensity on diffusion-weighted MR images and low apparent diffusion coefficient values (similar to the findings in acute cerebral infarction) were reported in such diverse conditions as hemorrhage, abscess, lymphoma, and even Creutzfeldt-Jakob disease. grand harbor sc real estate
