Answer- A. Transcranial ultrasound Diagnostic Procedures:Polygraphic video-EEG recording ofsuspected events is probably mandatory for an incontroveible seizure diagnosis.It is performed at the bedside and provides effective assessment of ventricular size and other fluid-containing lesions as well as effective viewing of haemorrhagic and ischaemic lesions and their evolution.CT brain scan is often of secondary or adjunctive impoance to ultrasound. Last-generation CT brain scan imagesare of high resolution, can be generated within seconds and can accurately detect haemorrhage, infarction, grossmalformations and ventricular and other pathological conditions.MRI is much superior for abnormalities of coical development used for the detection of structural abnormalitiessuch as malformations of coical development, intracranial haemorrhage, hydrocephalus and cerebral infarction.
