Acute disseminated encephalomyelitis (ADEM) may be a rapidly progressive disease with different clinical outcomes. ⋯ DWI is not always helpful for evaluating the evolution or predicting the outcome of ADEM. However, extension of the lesions, particularly brainstem involvement, may have an influence on the prognosis.

Magnetic resonance (MR) imaging has been established as the best imaging modality for the detection, localization, and staging of uterine cancers. Recently, the usefulness of diffusion-weighted imaging (DWI) in the diagnosis of cancers has been reported in several studies. ⋯ The present study shows that ADC measurements have the potential to quantitatively differentiate between normal and cancerous tissues of the uterine zones. We propose adding DWI as an adjunct sequence in the MR protocol for the assessment of uterine lesions.

Rat model of reperfused partial liver infarction (RPLI) has been increasingly used in studying new diagnostics and therapeutics. ⋯ RPLI in rats could be characterized by multiparametric MRI and postmortem assessments, with insight into the no-reflow phenomenon, which implies its further application for preclinical assessments of new pharmaceutics.

A relative paucity of data exists in the literature with regard to the utility of fluorodeoxyglucose positron emission tomography (FDG-PET) imaging in the clinical management of patients with primary lymphoma of the thyroid gland (PTL). ⋯ FDG-PET is a useful and sensitive modality for assessing disease activity in thyroid lymphoma. Its ability to detect disease recurrence was found to be superior compared to CT in two patients.

Human nephrogenic systemic fibrosis (NSF) is a rare condition reported in patients with severe renal insufficiency exposed to a gadolinium (Gd)-based contrast agent. An animal model of NSF could help to investigate its mechanisms and lead to prevention and treatment. ⋯ The visible skin lesions seen in this study appeared to be caused by excessive scratching in response to pruritus. As there was no evidence of dermal fibrosis, the cardinal feature of human NSF, this did not appear to be a model of human NSF.
