Performance of RAPID noncontrast CT stroke platform in large vessel occlusion and intracranial hemorrhage detection.

Background: Noncontrast CT (NCCT) is used to evaluate for intracerebral hemorrhage (ICH) and ischemia in acute ischemic stroke (AIS). Large vessel occlusions (LVOs) are a major cause of AIS, but challenging to detect on NCCT.

Aims: The purpose of this study is to evaluate an AI software called RAPID NCCT Stroke (RAPID, iSchemaView, Menlo Park, CA) for ICH and LVO detection compared to expert readers.

Syndromes with focal femoral deficiency: strengths and weaknesses of prenatal sonography.

Objective: To further characterize the prenatal diagnosis of proximal focal femoral deficiency and to contrast this entity with a variety of other "syndromes" in which the femur may be deficient.

Methods: We report 2 cases of proximal focal femoral deficiency and a case of femoral-facial syndrome.

Results: A series of 3 women whose fetuses had deficiency of 1 or both femurs were carefully analyzed for severity and for similarities and differences with other syndromes in which the femur may be deficient, as well as syndromes showing global skeletal abnormalities.
