Early rebleeding after coiling of a ruptured intracranial aneurysm (IA) may cause disability or death. The incidence and predictors of early rebleeding have previously been sparsely investigated. ⋯ The incidence of early rebleeding after acutely coiled ruptured IA was 3.6%. Risk factors for post-procedural rehemorrhage were the presence of ICH on the initial CT and HH grade 3–5 before coiling. Early rebleeding appeared exclusively as an enlargement of the initial ICH and not an increased amount of blood in the subarachnoid space.

Enhancement characteristics of breast lesions are regarded as a major criterion for their differential diagnosis in dynamic breast MRI (bMRI). However, ductal carcinoma in situ (DCIS) exhibits a highly heterogeneous enhancement pattern when kinetic analysis is performed conventionally by manual placement of region of interest (ROI) and therefore its diagnosis remains challenging. ⋯ The detection of suspicious enhancement curves could not be significantly increased in DCIS lesions when using computer-aided analysis despite a significantly higher detection rate of washout curves alone.
