Neurosurgeon and neuroradiologist Hugo Ramirez Luna, MD, and hemodynamic technician T. R. Gilberto Cesar Calvo Garcia, MD, of the Oaxaca Regional Hospital in Oaxaca, Mexico, have published a case study on neurosurgical clipping visualized with Siemens’ syngo^® iDentify^®. This technique enables the differentiation between two high-contrast 3D objects that have virtually the same contrast density and allows the display of syngo DynaCT^® and 3D angiography in one view.

An 18-year-old female patient was diagnosed with subarachnoid hemorrhage, which indicates a ruptured cerebral aneurysm. She also suffered from moderate to severe headache and nuchal rigidity, but showed no neurologic deficit other than cranial nerve palsy. The appearance of the subarachnoid hemorrhage on a computed tomography (CT) scan was non-evident. For the treatment, the physicians also relied on Siemens technology. A small, saccular aneurysm of the left posterior-communicant aneurysm was shown by DSA. Three-dimensional imaging with syngo InSpace 3D for better visualization of the vessel tree and localization of the aneurysm (Fig. 1) following a clipping – a Yasargil clip – was performed to treat the aneurysm. syngo iDentify helped confirm the successful clipping (Fig. 2: shows clip (green) and the vessel tree in red).
