Early and accurate diagnosis of brain tumors, a lethal disease caused by the abnormal growth cells in brain, is imperative to increase survival rates. A popular method for detection, diagnosis, treatment magnetic reasoning imaging (MRI) because it non-invasive provides high-quality visuals. Unfortunately, analyzing them manually can often be time-consuming requires medical expertise. Image clas...

Background: The touch preparation technique is an accurate and rapid method, and when used as intraoperative consultation examination technique it preserves a good amount of tissue for paraffin embedded sections. This study aimed at examining the accuracy of the touch preparation technique by comparing its diagnosis with that of final pathological diagnosis made by microscopic examinations. ...
