Radiology is a constantly evolving specialty with enormous responsibility, as radiologists often make the diagnosis to be treated. Large volumes of data increasing over time lead to a shortage of radiologistsʼ time. The use of systems based on artificial intelligence (AI) offers opportunities to relieve the burden on radiologists. Radiologists must understand the basic features of the technical function of the AI system in order to be able to assess the weaknesses and possible errors of the system and use the strengths of the system. This "explainability" creates trust in an AI system and shows its limits.
Neuroradiological diagnosis and therapy of cerebral vasospasm after subarachnoid hemorrhage
Alexander Neumann, Hannes Schacht, Peter Schramm
Cerebral damage after aneurysmal subarachnoid hemorrhage (SAH) results from various, sometimes unrelated causes. After the initial hemorrhage trauma with an increase in intracranial pressure, induced vasoconstriction, but also microcirculatory disturbances, inflammation and pathological electrophysiological processes can occur in the course of the disease, resulting in delayed cerebral ischemia (DCI). In the neuroradiological context, cerebral vasospasm (CVS) remains the focus of diagnostic imaging and endovascular therapy as a frequent component of the genesis of DCI. This review summarizes the current findings on the diagnosis and treatment of CVS after aneurysmal SAH from a neuroradiological perspective, taking into account the complex and up-to-date international literature.

Primary bone tumors are rare with variable histology and biologic aggressivity. In 2020, the World Health Organization published an updated classification for bone tumors. Management of primary bone sarcomas can be challenging due to their rarity and heterogeneity and requires a multi-disciplinary approach. Radiologists play a central role in the detection and characterization of asymptomatic (or incidentally detected) and symptomatic bone tumors. Accurate radiology reports can initiate appropriate management pathway, if required. There are four major reporting systems with the goal of standardized and systematic reporting of the imaging studies of bone tumors - each has its advantages and disadvantages.
