Optic neuropathy in imaging.

The aim of this work is to provide a diagnostic approach to the potential causes of optic neuropathy, focusing on the radiological findings associated with this pathology. Various etiologies have been identified, including inflammatory and demyelinating optic neuritis, developmental and hereditary diseases, neurodegenerative disorders, infectious conditions, post-traumatic causes, ischemic optic neuropathy (with anterior ischemic optic neuropathy being the most common form), and neoplastic etiologies. Optical coherence tomography and magnetic resonance imaging play a fundamental role in the diagnosis of optic neuropathy, allowing to distinguish patterns of optic nerve involvement.

Medication-related osteonecrosis of the jaw: the radiologist's role.

In recent decades, the dreaded adverse effect of bisphosphonates, osteonecrosis of the jaw, has been widely reported and described in detail. Osteonecrosis of the jaw consists of the destruction of part of the maxilla as a consequence of these antiresorptive drugs. In recent years, new drugs that can also cause osteonecrosis of the jaw (e.

Brain CT requests from emergency department: Reality.

Objectives: To evaluate the most common reasons for requesting brain CT studies from the emergency department and to calculate the prevalence of urgent acute pathology on this population group.

Material And Methods: We reviewed brain CT studies requested from the emergency department during October and November 2018. We recorded the following variables: age, sex, reason for requesting the study, CT findings, use of contrast agents and reasons for using them, and, in patients who had undergone previous head CT studies, whether the findings had changed.

[Valuation of automatized ASPECTS as an artificial intelligence tool in daily clinical].

Aims: To evaluate an automated ASPECTS (ASPECTS-a) software against two radiologists' reading of CT scans requested from the Emergency Department. Describe the most frequent failures of the ASPECTS-a.

Material And Methods: All the cranial CT Scans requested by the Emergency Department in one month were collected.

Inner ear MRI: is it always useful to manage intravenous contrast?

Objective: To evaluate the added value of administering intravenous contrast (IVC) routinely to the MRI of patients with audiovestibular symptoms in the assessment of a neuroradiologist and a resident.

Materials And Methods: Retrospective study including patients who had an inner ear MRI for two months. Two radiologists reviewed independently and blinded the images.
