The idea that assessment is intrinsic to effective instruction is traced from early experiments in the individualization of learning through the work of Benjamin Bloom to reviews of the impact of feedback on learners in classrooms.
Incidental hypervascular lesions are also very common findings in liver imaging. It is important to differentiate between 'touch' and 'don't touch' lesions. Benign 'don't touch' hypervascular tumors include hemangioma, FNH and small adenomas.
The hypointense liver lesion on T2-weighted MR images and what it means. Curvo-Semedo L, Brito JB, Seco MF, Costa JF, Marques CB, Caseiro-Alves F. The vast majority of focal liver lesions are hyperintense on T2-weighted magnetic resonance (MR) images.Rarely, however, hepatic nodules may appear totally or partially hypointense on those images.he aims of this work are to discuss the causes and mechanisms of hypointensity of liver lesions on T2-weighted images and proposing an algorithm for classification that may be useful as a quick reminder for the interested reader.
