WebSep 18, 2024 · On reviewing MR imaging, consider signal intensity, contrast enhancement, lesion location, association with anatomic structures, findings on radiographs, patient history, examination, and demographics. • Some solid masses have high T2 signal intensity and can be mistaken for cysts. Intravenous contrast helps in making the distinction. • WebOct 7, 2024 · Intramedullary cord hyperintensity at T2-weighted MRI is a common imaging feature of disease in the spinal cord, but it is nonspecific. Radiologists play a valuable role in helping narrow the differential diagnosis by integrating patient history and laboratory test results with key imaging characteristics. The authors present an algorithmic approach to …

WebThe signal intensity on T2-weighted images is primarily judged by comparing the signal intensity of the lesion with that of normal parotid gland or adjacent muscles, and the observer subjectively evaluates the signal as high, equal, or low. ... Compared with the parotid gland with high signal intensity due to more fat in stroma, most parotid ... WebThe lesions typically are hypointense on T1 and hyperintense on T2 compared to liver parenchyma. Classically, the lesions are hyperintense, almost "light bulb" bright on T2-weighted imaging. This feature helps distinguish them from malignant lesions, which are typically of intermediate signal on T2 imaging. imit thailand
