INTRODUCTION: Prognosticating outcome after cardiac arrest(CA) requires a multimodal approach. However, evidence regarding combinations of methods is limited. We evaluated whether the combination of electroencephalography(EEG), somatosensory evoked potentials(SEPs) and brain computed tomography(CT) could predict poor outcome. METHODS: We screened our database regarding patients successfully resuscitated after CA, for whom EEG, SEPs and brain CT were available within 24 hours...

INTRODUCTION: Haemorrhagic stroke is of significant healthcare concern due to its association with high mortality and lasting impact on the survivors' quality of life. Treatment decisions and clinical outcomes depend strongly on the size, spread and location of the haematoma. Non-contrast CT (NCCT) is the primary neuroimaging modality for haematoma assessment in haemorrhagic stroke diagnosis. Current procedures do not allow convenient NCCT-based haemorrhage volume calculation in clinical settings, while research-based approaches are yet to be tested for clinical utility; there is a demonstrated need for developing effective solutions...

Posterior reversible encephalopathy syndrome (PRES) is a clinico-neuroradiological entity, first described in 1996. It is commonly associated with systemic hypertension, intake of immunosuppressant drugs, sepsis and eclampsia and preeclampsia. Headache, alteration in consciousness, visual disturbances and seizures are common manifestations of PRES. Signs of pyramidal tract involvement and motor dysfunction are uncommon clinical findings. However, clinical presentation is not diagnostic. On neuroimaging, lesions are characteristically found in parieto occipital region of the brain due to vasogenic edema...

BACKGROUND AND PURPOSE: With globalization, the contributions of authors from abroad to the American published literature has increased. We sought to determine the changes with time in the proportional contributions of American and non-American authors in the American neurosciences literature. We hypothesized the following: 1) During the past 21 years, manuscript contributions of American institutions have proportionally decreased in neuroradiology, more than in neurosurgery or neurology; 2) contributions of Asian institutions have affected neuroradiology more than neurosurgery and neurology; and 3) American articles garner more citations...

OBJECTIVES: In order to enable less experienced physicians to reliably detect early signs of stroke, A novel approach was proposed to enhance the visual perception of ischemic stroke in non-enhanced CT. METHODS: A set of 39 retrospective CT scans were used, divided into 23 cases of acute ischemic stroke and 16 normal patients. Stroke cases were obtained within 4.5 h of symptom onset and with a mean NIHSS of 12.9±7.4. After selection of adjunct slices from the CT exam, image averaging was performed to reduce the noise and redundant information...

BACKGROUND: The Neurologic Assessment in Neuro-Oncology (NANO) scale is a standardized objective metric designed to measure neurological function in neuro-oncology. Current neuroradiological evaluation guidelines fail to use specific clinical criteria for progression. OBJECTIVE: To determine if the NANO scale was a reliable assessment tool in glioblastoma (GBM) patients and whether it correlated to survival. METHODS: Our group performed a retrospective review of all patients with newly diagnosed GBM from January 1, 2010, through December 31, 2012, at our institution...

BACKGROUND AND PURPOSE: The thyrocervical trunk (TCT) is the second ascending branch of the subclavian artery. It is considered a 'border territory' between interventional vascular radiology and interventional neuroradiology because it gives rise to branches both cervical and to the upper limbs. We describe the TCT branches anatomy, the most frequent variants, and expose eight endovascular procedures performed through the thyrocervical trunk. METHODS: A retrospective review of all the interventional radiology procedures carried out through the TCT in our tertiary care center from August 2014 to January 2017 is presented...
