Abstract
- The first-line imaging modality used to detect subarachnoid hemorrhage (SAH) is a non-contrast computed tomography (CT) scan. Although a CT scan shows great sensitivity for diagnosis of SAH, especially in the hyper-acute and acute stages, it sometimes shows negative results despite typical symptoms. It is thought that the small amount of blood causing the hemorrage and the delay time of the CT scans were the causes of the negative results. Two patients presented to us with SAH, but initial CT scans were negative. We diagnosed the SAH of these patients using magnetic resonance images.
