non diagnosed stroke

If a patient is admitted to hospital with stroke symptoms but a CT scan doesnt diagnose it, then the symptoms improve,  is it the standard  of care to  give the patient an MRI scan which can detect a stroke within minutes of occurring?  Is it against the standarfd of care to alllow 5 hours to elapse without a diagnosis therefore losing the opportunity to admnister stroke busting drugs?

Hi there. For diagnosing ischemic stroke MRI is more sensitive and specific than CT, for hemorrhagic stroke, they both are comparable and for chronic hemorrhages, MRI is more sensitive. Therefore, with the presentation of a stroke, a quick neurological examination should be followed up by an MRI head for a prompt diagnosis and empirical therapy. It would be medical negligence if time as good as 5 hours is lost before therapy was started. Immediate period following stroke is crucial for the extent of irreversible neurological damage. Therapy depends on the type of the stroke and includes drugs like anticoagulants and antithrombotic for ischemic stroke, the same could be hazardous for hemorrhagic stroke. Hope this helps. Take care.
