Teleradiology solutions are playing an essential role during the COVID-19 outbreak. Activity at radiology departments must be maintained and adapted to this new situation beyond teleradiology. Teleworking should be extended to the rest of non-medical radiology department areas. A comprehensive perspective based on our own experience during the COVID-19 outbreak has been performed highlighting the value of teleworking for almost all areas implied in the workflow of radiology departments beyond radiologists. Personal and technical requirements for successfully adapting to this new scenario are discussed including the opportunities that this unprecedent situation is bringing for reorganizing workflow and developing new projects.

A 70-year-old woman with osteoporosis fell at home and presented to our emergency department with intense left hip pain. Radiographs revealed a left iliopubic rami fracture and nondisplaced right ischiopubic rami fracture. She was discharged after a 24-hour observation with no clinical changes. Seventy-two hours later, she was readmitted with a painful abdominal mass, progressive oliguria, tachycardia, hypotension, and profuse perspiration with generalized pallor. On physical examination, a painful mass in the hypogastrium and intense inflammation in the thigh and the proximal portion of left knee were found.Emergent multiphase contrast computed tomography revealed a large nonhomogeneous hematoma neighboring the fractured left iliopubic rami, and contrast extravasation indicated arterial bleeding. Selective angiography showed an active hemorrhage from the distal portion of a small branch of the left obturator artery. After embolization of the arterial vessel, the patient was hemodynamically stable. The fracture was rotationally and vertically stable.These fractures are common, especially among the elderly. This type of injury is usually treated conservatively and with active mobilization once the acute pain has subsided. Supraselective embolization after localization of the bleeding vessels by arteriography is recognized as a minimally invasive procedure with excellent outcomes in hemorrhagic complications of pelvic fractures. An apparently benign pubic rami fracture in the setting of hemodynamic instability should raise the suspicion of a corona mortis injury, especially in elderly and anticoagulated patients.

Evaluation of Central Nervous System (CNS) focal lesions has been classically made focusing on the assessment solid or enhancing component. However, the assessment of solitary peripherally enhancing lesions where the differential diagnosis includes High-Grade Gliomas (HGG) and metastasis, is usually challenging. Several studies have tried to address the characteristics of peritumoral non-enhancing areas, for better characterization of these lesions. Peritumoral hyperintense T2/FLAIR signal abnormality predominantly contains infiltrating tumor cells in HGG whereas CNS metastasis induce pure vasogenic edema. In addition, the accurate determination of the real extension of HGG is critical for treatment selection and outcome. Conventional MRI sequences are limited in distinguishing infiltrating neoplasm from vasogenic edema. Advanced MRI sequences like Diffusion Weighted Imaging (DWI), Diffusion Tensor Imaging (DTI), Perfusion Weighted Imaging (PWI) and MR spectroscopy (MRS) have all been utilized for this aim with acceptable results. Other advanced MRI approaches, less explored for this task such as Arterial Spin Labelling (ASL), Diffusion Kurtosis Imaging (DKI), T2 relaxometry or Amide Proton Transfer (APT) are also showning promising results in this scenario. In this article, we will discuss the physiopathological basis of peritumoral T2/FLAIR signal abnormality and review potential applications of advanced MRI sequences for its evaluation.
