![]() Hydrocephalus is a buildup of fluid in the ventricles of the brain, which can be caused by a range of different factors ( 1). Keywords: Intracranial pressure (ICP) phase-contrast cine MRI (PC-MRI) cerebrospinal fluid (CSF) correlation parameters These findings can be useful in assisting clinicians in predicting ICP more effectively, thus improving patient management. The ICP increased with the average velocity above 1.628 cm/s (P≤0.01), and the aqueduct diameter increased more than 3.6 mm (P<0.001).Ĭonclusions: This study found significant correlations between ICP and average velocity and aqueduct diameter. Furthermore, a nonlinear relationship was observed between the ICP and the average velocity of CSF, and the ICP and aqueduct diameter. Results: The mean ICP and CSF aqueduct diameter in hydrocephalus patients were 151.05 mmH 2O and 2.877 mm, respectively, and the maximum (6.938 cm/s) and mean (0.845 cm/s) CSF flow velocities were significantly higher in these patients compared with the controls (P0.05). In addition to recording patient’s age, heart rate, blood pressure and body mass index (BMI), ICP and CSF hemodynamic parameters, such as flow velocity and aqueduct diameter, were measured for correlation analysis. Methods: Fifteen normal people and 80 subjects with communicating hydrocephalus who underwent PC-MRI examinations from a single center were included in this cross-sectional study. Policy of Dealing with Allegations of Research Misconductīackground: To explore the correlation between intracranial pressure (ICP) and cerebrospinal fluid (CSF) parameters assessed by phase-contrast cine MRI (PC-MRI).Policy of Screening for Plagiarism Process.Patients receiving premedication can be scheduled at any of our locations EXCEPT for MINS (Medical Imaging of North Stafford). Patients receiving premedication can be scheduled at any of our locations EXCEPT for MINS (Medical Imaging of North Stafford).Īny patients requiring Benadryl premedication will need to be accompanied by a driver due to the associated drowsiness from this medication. Diphenhydramine (Benadryl®): 50 mg by mouth 1 hour before contrast medium.Prednisone: 50 mg by mouth at 13 hours, 7 hours, and 1 hour before contrast media injection and.What is the suggested premedication protocol? Where can these patients be imaged? Call (540) 741-1571 to speak to a radiologist. This includes any reaction that required urgent medical care. Patients with prior anaphylactic reactions to imaging contrast agents (ex: iodinated contrast for CT, gadolinium for MRI) need to be discussed with a radiologist prior to scheduling to determine if an alternative test could be performed.Patients with prior severe life-threatening reaction to ANY substance, other than iodinated contrast, that required hospitalization are recommended to have our standard premedication protocol prior to iodinated IV contrast injection.What about patients with history of anaphylaxis? ![]() Scan location in these instances would depend on the clinical scenario. SEVERE REACTIONS – laryngeal edema, severe shortness of breath, or anaphylactoid response need to be discussed with a radiologist prior to scheduling to determine if an alternative test can answer the clinical question. MILD REACTIONS – hives, nasal congestion, itching, mild shortness of breath can be performed at any facility and require the premedication as described below. These drugs will not prevent or alleviate these symptoms. ![]() Patients who have only had vasovagal reactions, nausea, vomiting, or contrast-induced renal dysfunction do NOT need steroid/antihistamine premedication.
