Ischemic stroke is a medical emergency requiring fast and effective collaboration of neurologists and radiologists. Currently there are promising new developments in the treatment of acute ischemic stroke with efforts being made to reduce the door-to-needle time and to improve recanalization of occluded vessels by new endovascular techniques. Clinical trials have also demonstrated the efficacy of thrombolysis up to 4.5 h and confirmed the importance of the time to treatment for positive outcome.

Imaging in monoclonal plasma cell disease serves to detect end organ damage, i.e., osteoporosis or bone destruction. Diffuse or circumscribed bone marrow infiltration without damage to mineralized bone is so far not regarded as end organ damage. ⋯ For the initial diagnosis of monoclonal gammopathy of undetermined significance (MGUS), smoldering multiple myeloma or symptomatic multiple myeloma, a whole-body MRI and a whole body low-dose CT should be performed. For MGUS and asymptomatic myeloma, whole body MRI only should be performed for follow-up until detection of first bone destruction. Patients with symptomatic multiple myeloma and known bone destruction will usually have whole body low-dose CT, supplemented by MRI studies where clinically required.
