Precise identification of the epileptogenic focus following subtraction of MRI (3D T1) co-registered, ictal and interictal SPECT images acquired using the radiopharmaceuticals 99mTc-HMPAO and 99mTc-ECD.

Neurocloud-SISCOM improves the location of surgical seizure focus, which translates into an improved surgery outcome by increasing the possibility of complete extraction of the focus.
