Patients with triple-negative breast cancer (TNBC) are at increased risk of brain metastases (BMs). In this retrospective single-institutional study, we assessed the radiographic features from a cohort of breast cancer (BC) patients with confirmed BM. ⋯ Patients with BMs from TNBC have distinct MRI features helping the assessment of newly developed BM. A large confirmatory study with correlated histology in this unique patient population will be required.

We investigated the relationship between transcranial Doppler (TCD) pulsatility index (PI) and central aortic pressure by measurement of the aortic augmentation index (AIx). ⋯ TCD PI was significantly related with central aortic pressure, especially PP. The PI in the MCA and BA is closely associated with the pulsatile component of BP in the systemic circulation.

The aim of this study is to explore the possible changed cerebral white matter regions in patients with temporal lobe epilepsy (TLE) using diffusion tensor imaging (DTI) and tract-based spatial statistics (TBSS). ⋯ TLE is associated with widespread abnormalities in cerebral white matter tracts and these changes may have important clinical consequences.

Observational Study
Diagnostic and Prognostic Impact of pc-ASPECTS Applied to Perfusion CT in the Basilar Artery International Cooperation Study.
The posterior circulation Acute Stroke Prognosis Early CT Score (pc-APECTS) applied to CT angiography source images (CTA-SI) predicts the functional outcome of patients in the Basilar Artery International Cooperation Study (BASICS). We assessed the diagnostic and prognostic impact of pc-ASPECTS applied to perfusion CT (CTP) in the BASICS registry population. ⋯ CTP was performed in a minority of the BASICS registry population. Perfusion disturbances in the posterior circulation were most pronounced on MTT parameter maps. CBV pc-ASPECTS < 8 may indicate patients with high case fatality.
