What is a T2 hypointense lesion?

T2 heterogeneous hypointense or mixed signal solid lesions have intermediate signal or T2 inhomogeneous signal with a mixture of T2 low and bright signal (higher than that of the outer myometrium or skeletal muscle). These may represent either benign or malignant lesions, either primary or secondary 3, 8.

What is a T2 hypointense mass?

A hypointense ovarian lesion on T2 weighted MRI is usually a sign of benignity. The low signal is considered to be due to fibrosis and blood products 1. Lesions that can give this appearance include 1: endometrioma.

What is a T2 lesion in brain?

T2/FLAIR images show the total amount of scar from MS from its onset. The pictures show both old and new inflammation. T2/FLAIR lesions can directly account for some symptoms. For example, a brainstem lesion can cause room spinning sensations and balance problems.

What is Hypointensity in the brain?

Abstract. T1 -hypointense lesions (T1-black holes) in multiple sclerosis (MS) are areas of relatively severe central nervous system (CNS) damage compared with the more non-specific T2-hyperintense lesions, which show greater signal intensity than normal brain on T2-weighted magnetic resonance imaging (MRI).

What is hyperintense T2?

Hyperintensity on a T2 sequence MRI basically means that the brain tissue in that particular spot differs from the rest of the brain. A bright spot, or hyperintensity, on T2 scan is nonspecific by itself and must be interpreted within clinical context (symptoms, why you had the MRI done in the first place, etc).

What is T2 hyperintensity?

Hyperintensity on a T2 sequence MRI basically means that the brain tissue in that particular spot differs from the rest of the brain. A bright spot, or hyperintensity , on T2 scan is nonspecific by itself and must be interpreted within clinical context (symptoms, why you had the MRI done in the first place, etc).

What does heterogeneous T2 Pons signal indicate?

Heterogeneous signal on T2 weighted images may be due to demyelination,ischemia etc. Normally there are no focal focal bright lesions on T2 weighted images. Pons lesions may cause dysphagia. It is important to see lesions in other areas of brain like peri ventricular region,corpus callosum of brain.
