Regional and global T2 hyperintense and T1 hypointense parenchymal lesion loads were ordinally rated. Enlargement of subarachnoid and ventricular spaces (atrophy) was ordinally rated vs. age- and gender-matched normal controls. T2 hypointensity was highly, positively correlated with many other MRI ...
An implantable rat liver tumor model for experimental transarterial chemoembolization therapy and its imaging features. The tumors were hypodensity on CT, hypointense on MR T1-weighted and hyperintense on T2-weighted. The model closely resembled human hepatocarcinoma in ... Xin,Li,Chuan-Sheng,... ...
Because cholangiocarcinoma shows no specific clinical signs or symptoms and presents with non-specific biological and tumor markers in the early stages, MRI findings often lack typical features before this lesion becomes symptomatic and might be mistaken for other liver lesions. An evaluation of relevant...
The classification of lesions based on their hypointense or hyperintense appearance is hampered by the influence of field strength and pulse sequence parameters. An alternative approach (but not commonly used today, clinically) is to calculate tissue relaxation times, thus providing a quantitative ...
# Pelvic endometriosis lesions can exhibit T1-hyperintensity across their three phenotypes.# A definitive diagnosis of a T1-hyperintense endometriotic lesion is crucial for patient management.# Hemorrhages, high protein concentrations, lipids, and artifacts are the main sources of T1-hyperintense mimickers...

AIM: To evaluate the relationship between the total brain T2-hyperintense lesion volume (TBT2LV) and the axonal damage in the normal-appearing white matter of brainstem measured by 1H-MRS in a group of early patients. SUBJECTS AND METHODS: 40 relapsing-remitting patients and ten sex- and age...
Atrophied T2 Hyperintense Lesion Volume is Highly Predictive of Disability Progression. A 2-year Longitudinal Study Using Voxel-Wise Dynamic ClassificationZivadinov, RBergsland, NFritz, DHani, NNussenbaum, FWeinstockGuttman, BDurfee, JAbdelrahman, N...
In T2-weighted TSE images, breast cancers were iso- or hypointense with respect to breast parenchyma in 87% of cases, whereas fibroadenomas were hyperintense in 71%. Visual assessment of lesion appearance in T2-weighted TSE images allowed to distinguish between fibroadenomas and breast cancers, ...
