Magnetic Resonance Imaging Compared to CT Scan

Case Study One (Part 1)

Case Description:
This patient's imaging studies show evolution of a left cerebral artery infarct on CT scan and MRI.

 

Computed tomography of the head done 1/7/97 shows a hyperacute infarct, which is seen only by the effacment of the cerebral sulci in the left parietal region and suggestion of loss of grey/white distinction.

T2- weighted MRI scan shows no obvious signal abnormality.

Contrast-enhanced T1-weighted image shows slightly prominent intravascular contrast enhancement within the branches of the left middle cerebral artery.  Otherwise, the T1-weighted images show no obvious abnormality.
