Once suspected, intracranial aneurysms can be diagnosed radiologically using magnetic resonance or CT angiography. They constitute a wide array of disorders with clinically and radiologically diverse manifestations. It was found that the two syndromes were distinct clinically, radiologically, and genetically. Siva and colleagues suggested an alternate name, radiologically uncovered asymptomatic possible inflammatory-demyelinating disease (RAPIDD). PVNS is radiologically diagnosed by magnetic resonance imaging (MRI). The MOG-related neuromyelitis optica can be radiologically identified by the conus involvement. In 1913 more than 5,000 patients were examined radiologically. Treatment is by prompt neurosurgery or radiologically guided interventions. A "radiologically enhanced weapon", or "dirty bomb", uses an explosive to spread radioactive material. The sample is then centrifuged and compared radiologically to a control. Aged U-233 is self-protected radiologically from diversion. This is often named "Radiologically Isolated Syndrome" (RIS). Radiologically tumors are grouped based on appearance into simple cystic, complex cystic, or solid. Radiologically the tumors may show characteristic 'soap bubble' appearance.
