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
A head magnetic resonance imaging scan, or MRI, is a test that produces images of the brain using a strong magnetic field and radio-wave energy, according to WebMD. It typically offers useful information that X-ray, ultrasound and computer tomography scans cannot provide.Full Answer >

A hypodense liver lesion is an abnormality that is less dense than the surrounding liver tissue as seen in a radiological scan, such as a Computed Tomography scan or Magnetic Resonance Imaging, explains HealthTap. Hypodense liver lesions range from benign cysts to cancerous metastases, according to the Radiology Assistant.Full Answer >
A hypoattenuating lesion is an area on an organ that appears brighter than the rest of the organ on an X-ray or CT scan. The brighter area on the image of the organ indicates some sort of abnormality to the surface.Full Answer >
