So-called T1-weighted (T1W) images are produced by keeping TR and TE relatively short. Under these conditions, contrast between structures is based primarily on their T1 relaxation differences. T2-weighted (T2W) images are produced by using longer TR and TE times.

MRI was sporadically reported [21]: (1) the normal thyroid gland was homogeneously hyperintense relative to the neck muscles on both T1- and T2-weighted images; (2) the tuberculous lesion showed an intermediate signal on both T1- and T2-weighted images, the signal intensity was higher than normal glandular parenchyma due to the presence of ...

At MR the lesion is hypointense on T1- and hyperintense on T2-weighted images. This lesion may be hyperintense on T1-weighted images due to mucinous content. Intraductal papillary mucinous tumor of the pancreas. Intraductal papillary mucinous tumor of the pancreas (IPMN) are most frequent indentified in …

DWI is particularly useful as an initial screening tool for liver study as nearly 70%-95% of HCCs can appear hyperintense[21]. Although DWI is high sensitive in detecting liver nodules, it cannot accurately distinguish between HCC and dysplastic nodules or other malignant and benign liver lesions.

We have shown that D* and f values can reflect liver lesions perfusion since hypervascular liver lesions had significantly greater D* and f values than intermediate and non hypervascular lesions. A biexponential approach might be useful for the characterization of liver lesions and the assessment of tumour response. Tuesday 13:30-15:30 Computer 101

: In a Phase 2b study in patients with multiple sclerosis, ‘168 reduced Gd-enhancing T1 hyperintense lesions by 85% compared to placebo. In June, Sanofi announced the first multiple sclerosis patient was enrolled in the Phase 3 program for the BTK inhibitor, comprising four pivotal clinical trials across the disease spectrum.

Small punctuate hyperintense focal lesions in subcortical and periventricular WM on T2-weighted and FLAIR images, without contrast enhancement; T1–weighted signals are usually normal. Sensitivity 51% for acute NPSLE (54% in major, 30% in minor NPSLE); increased in focal than diffuse major NPSLE (79% versus 48%)

T2 hyperintense lesions plaques are circumscribed and lack mass effect (except occasional large plaques, but mass effect is still disproportionally small!). some T2 foci extend outward from ventricular surface, corresponding to pattern of perivenous demyelination that …
