The diagnosis from Covid-19 provides the set of several examinations such as: clinical examinations, laboratory examinations, radiographic examinations. Using radiological imaging, RX and chest CT, it is possible to evaluate the impairment of lung function and thanks to this aspect it is possible to define the severity and clinical conditions of the patient. In this way, it allows timely therapeutic intervention especially if the patient shows a mild condition in such a way as to avoid the onset of further complications. Chest X-rays allow both an initial assessment of patients and the possibility to perform a differential diagnosis towards other possible causes of lung parenchyma involvement. The CT scan, which highlights the peculiar characteristics of COVID pneumonia, is performed both as diagnostic confirmation and in the patient’s follow-up.

Cerebrovascular diseases are abnormalities of the intracranial vascular system, affecting its ability to carry blood to the brain. The pathogenesis of many of these begins in the wall of the vessel and actual imaging techniques are not able to visualize the vascular wall. Moreover, perfusion imaging techniques do not provide adequate information on the differentiation, onset or progression of the disease. Recently, imaging of vessel walls with magnetic resonance imaging (VWI) allowed to visualize sub-millimeter structures of the arterial wall, emerging as a valuable technique for understanding and evaluating cerebrovascular diseases. Localization of the lesion and characteristic aspects with contrast medium provide therefore new information on the inflammatory etiology of cerebrovascular diseases, such as intracranial steno-occlusive disease, identification of atherosclerotic plaques, localization of vessel pathology in areas with minimal or zero waist to luminal imaging and stability of the aneurysm allowing early diagnosis and treatment. In recent years, intracranial vessel wall (VW) magnetic resonance (MR) imaging has been an exponential increase in popularity and clinical applicability. However, increasing evidence shows that also the intracranial atherosclerosis might be a potential cause of ischemic stroke, focusing the toward the imaging of the intracranial vasculature. The following descriptive study has been carried out on some patients of the University Hospital “San Giovanni di Dio e Ruggi d’Aragona”, using a 3-T MR. This study describes the effectiveness of the magnetic resonance vessel wall imaging in cerebrovascular diseases.

Umbilical vessel catheterization is a technique used for neonatal reanimation, in neonatal intensive care units. Imaging techniques provide a strong support for the performance of this practice. In this case, radiography is the most widely used instrumental investigation for the evaluation of umbilical venous catheter placement. By protocol, the image is acquired with an antero-posterior projection of the thoraco-abdominal district, with perpendicular radius to the median sagittal plane. The following descriptive study has been carried out on 20 newborn patients of the Neonatal Intensive Care Unit of the University Hospital “San Giovanni di Dio e Ruggi d’Aragona”, born between December 4th 2020 and March 31th 2021. This study describes the effectiveness of the “thoraco-abdominal” radiological technique for the assessment of neonatal umbilical catheter placement. The basic premise for patients’ recruitment was the request for evaluation of umbilical venous catheter placement in preterm infants.
