TL;DR: In this large patient-level meta-analysis, models using four or five predictors had acceptable to good discrimination and could inform the location and frequency of observations on patients in clinical practice, explain treatment effects in prior randomised trials, and guide the design of future trials.

Feasibility of 4D flow MR imaging of the brain with either Cartesian y-z radial sampling or k-t SENSE: comparison with 4D Flow MR imaging using SENSE.
TL;DR: Cartesian y-z radial sampling is feasible for measuring flow, and k-t SENSE offers sufficient flow visualization; both allow acquisition of 4D Flow MR imaging with shorter scan time.
Subarachnoid haemorrhage and vasospasm due to pituitary apoplexy after pituitary function tests.
TL;DR: A unique case of a 55-year-old man who presented with severe headache after a combined pituitary function test, and computed tomography evidence of an infarction, with subsequent intratumoural haemorrhage and subrachnoid haem orrhage associated with vasospasm is reported.

Neuroimaging of primary central nervous system lymphoma in immunocompetent patients: comparison of recent and previous findings.
TL;DR: Atypical neuroimaging findings do not rule out PCNSL, even in immunocompetent patients and how imaging findings over the last 10 years differ from those from more than 10 years ago is analyzed.
