56 years Male (DOB:6/4/1960)Reason: evolution of stroke, r/o blood History: rt side weaknessPROVIDER/ATTENDING NAME: CHRISTOPHER L KRAMER CHRISTOPHER L KRAMER There is diffusion restriction associated with susceptibility effect involving left basal ganglia and adjacent left centrum semiovale. It is compatible patient's known area of infarction. On T1-weighted imaging it is hypointense in signal with the exception of a couple minor foci of signal hyperintensity. This suggests that potentially this is related to contrast rather than blood products. This corresponds to the area of diffusion restriction on the prior exam and extends to involve more of the lentiform nuclei and the current exam.Normal vascular flow voids are present in the distal carotid and vertebral arteries, the basilar artery and the proximal anterior, middle and posterior cerebral arteries as well as the internal cerebral veins and superior sagittal sinus.The visualized portions of the paranasal sinuses are clear. The visualized portions of the mastoid air cells are clear. The visualized portions of the orbits are intact.
There is diffusion restriction associated with susceptibility effect involving left basal ganglia and adjacent left centrum semiovale. It is compatible patient's known area of infarction. This susceptibility effect could be a result of contrast given the signal characteristics.
