In preparation for this procedure the patient may be asked to remove any metal and change into a gown. However, trauma studies are timed for the late arterial/early portal venous phase. For example, we work in a trauma center with a large oncology population, and we have learned that. Pediatric and adult reference protocols, a set of pre-loaded protocols on a CT system that serve as a baseline for a variety of clinical tasks. • Coronal brain imaging, preferably perpendicular to the long axis of the hippocampus, should be included in routine MRI protocols. 5 mm x 16 Detail 120 250 0. (A) axial brain CT, position of the ventriculo – peritoneal shunt catheter, (B) course of the catheters outside the skull in VRT. The decision as to whether to use axial or helical should be influenced by the specific patient indication, scanner capabilities, and image quality. PMID: 23127050 doi: 10. PECARN Pediatric Head Injury/Trauma Algorithm. Secondary outcome: Evidence of brain injury on CT. The Brainlab registration matrix with integrated MR markers is designed for use with a 3-pin skull clamp and therefore does not compromise standard patient positioning.
