A T2 hyperintense lesion is a very bright area seen on a magnetic resonance imaging scan using T2-weighting. A lesion is any abnormality seen on an MRI scan. T2 hyperintense lesions are usually dense areas of abnormal tissue.Know More
T2 hyperintense lesions in the brain are commonly seen with multiple sclerosis, small strokes, migraines, tumors, inflammation and many other conditions. T2 hyperintense lesions are seen in other organs, as well. For example, malignant liver tumors often appear as T2 hyperintense lesions.
MRI can acquire images with or without contrast, and by using either T1 or T2 weighting. Other methods of acquiring images, such as diffusion weighting and FLAIR, are also available. A full scan usually involves acquiring a number of images using different methods. The various methods of acquiring images reveal different properties of the tissues.Learn more about Conditions & Diseases
WebMD describes lytic lesions as weak areas of the bone. Also called osteolytic lesions, these lesions occur when multiple myeloma afflicts the body.

Choroid plexus xanthogranulomas are lesions of the choroid plexus of the brain's lateral ventricle. They aren't common and don't easily show up with the standard magnetic resonance imaging, but they are one type of lesion that is hyperintense with the nonenhancing T2 MRI technique, notes the American Journal of Neuroradiology.Full Answer >
A hyperechoic liver lesion is a region on that liver that shows up on an ultrasound. This can be the result of a number of different conditions, some benign and some malignant.Full Answer >
According to Dr. West at Cancer Grace, a low-attenuation lesion is a spot that appears on a radiographic image as less dense than the surrounding healthy tissue in that specific organ of the body. For example, a low-attenuation lesion could appear as a result of imaging on the liver, pancreas, kidney or thyroid.Full Answer >
