to CHD CT imaging that includes pediatric and adult cardiologists, cardiac imagers and surgeons. Several questions should be asked prior to selection of CT as the imaging test of choice in CHD: 1. Does the study indication justify the risks of CT (radiation and contrast exposure, anesthesia and/or medication for heart rate control when needed)? 2. Background The American College of Radiology Dose Index Registry for CT enables evaluation of radiation dose as a function of patient characteristics and examination type. The hypothesis of this study was that academic pediatric CT facilities have optimized CT protocols that may result in a lower and less variable radiation dose in children. Materials and Methods A retrospective study of doses The results of this survey illustrate the collective opinion of a subset of SPR members relating to the use of i.v. contrast media in pediatric CT, providing guidelines for clinical histories needed before i.v. contrast media, maximum i.v. contrast injection rates for standard angiocatheters, contra … It is important for reviewers to be aware that there may be significant differences between the dose estimates reported by some CT scanners for pediatric scans based on which phantom size (16 or 32 cm diameter) is used to report the CTDI vol values in the dose report. Though the manufacturers are converging on a standard for pediatric abdomen exams being reported with the 32 cm (body) CTDI Many principles of enteric contrast use in pediatric imaging are similar to those in adult imaging, but important differences must be kept in mind when imaging the gastrointestinal tract in infants and children, and practical ways to optimize the imaging examination and the patient experience should be employed where possible. CT Neck with contrast (includes jaw, and mandible) 70491 CT Neck without and with contrast (includes jaw, and mandible) 70492 CT Guidance for Placement of Radiation Therapy Fields 77014 Pediatric Neck Imaging Guidelines should be imaged according to the General Neck Imaging Guidelines. Patients who are ≥18 years old should be imaged 1) The Radiology nurse will determine the catheter type and size by visual inspection and review of documentation. Pediatric patients with non-power injectable central lines, in whom peripheral IV access cannot be obtained, may undergo contrast injection for a CT/MRI by hand injection into the following catheters: BARD tunneled 4.2 SL, 6.6 SL. For CT of the abdomen and pelvis, volume of administered IV contrast is based on child body weight, with 2 mL/kg up to a maximum of 100 mL. Contrast is injected via peripheral IV access by means of a power injector at a rate of 2 mL/s or by hand injection, depending upon the size of the peripheral IV access catheter. CT Image Evaluation Inform your doctor and the technologist prior to the exam if your child has a known allergy to contrast material. Your child should wear loose, comfortable clothing and may be asked to wear a gown. You may be instructed to withhold food or drink beforehand, especially if sedation or anesthesia is to be used. These suggestions are general guidelines that apply to the use of contrast for CT exams provided at Oregon Imaging Centers. If you have questions about ordering your patient's CT, we encourage you to speak with a radiologist about the study and the need for contrast.
