If you would like to speak to one of our radiologists for the best contrast guidelines for your patient, please call us directly.

One randomized controlled trial showed that premedication decreased the rate of allergic-like reactions in average-risk (with or without prior history of allergic-like reaction) patients exposed to older The UCSF Department of Radiology employs a practical but conservative approach to managing patients with a prior history of allergic-type reaction to intravascular iodinated contrast, stratified by severity of prior reaction.For several reasons, it is preferable for referring physicians to prescribe the premedication regimen, although other arrangements may be possible depending on individual circumstances. Please be assured these are recommendations only. The majority of reactions are mild non-life-threatening events that usually only require observation, reassurance, and/or supportive measures. This possible adverse effect has been termed contrast-induced nephropathy (CIN). Given the confounding factors present in these previous studies, the American College of Radiology has adopted the term post-contrast acute kidney injury (PC-AKI) for any sudden deterioration in renal function that occurs within 48 hours following intravascular administration of iodinated contrast and reserves the term contrast-induced nephropathy (CIN) for PC-AKI that is Recent studies [2-8] suggest that historical concern for CIN after administration of intravenous iodinated contrast was likely overstated. The use of cetirizine (Zyrtec®) instead of the previously recommended antihistamine diphenhydramine (Benadryl®) is preferred in adults due to the side effects associated with diphenhydramine (drowsiness). Treatment should then proceed as indicated based on the nature and severity of the acute contrast reaction.Specific ACR guidelines recommendations for management of acute contrast reactions based on category and severity:After managing an acute adverse event to intravascular contrast exposure, it is critical to analyze the event and determine whether the patient experienced an allergic-like reaction. The facility in Boca Raton on Glades Road is a beautiful facility and the staff is professional and friendly.

I had an appointment at 9:00 and was walking out at 9:07. Contrast extravasation is a well-recognized complication, with reported frequencies of 0.25% (56/22,254), 0.7% (475/69,657) and 0.9% (48/5,106) in three large CT series where power injectors were used [1-3]. Congrats to the team they built at this facilityGoing to DCA for my imaging was one of the best experiences I have had at a Health Care facility in a long time. It also impossible to conclude whether the increased morbidity and mortality seen in patients with PC-AKI is associated with intravascular iodinated contrast exposure or due to some other factor such as the underlying comorbid diseases present in these patients. Timing of CT-series is important in order to grab the right moment of maximal contrast differences between a lesion and the normal parenchyma. Kudos to the entire Delray DCA team. In patients taking Metformin who are known to have acute kidney injury or severe chronic kidney disease (stage IV or stage V), the contrast will not be administered unless the patient is scheduled for dialysis the next day or within 24 hours. These can be used as guidelines for hospital examinations. Reserved. Cardiopulmonary arrest is a nonspecific end-stage result that can be caused by a variety of the following severe reactions, both allergic-like and physiologic. The affected extremity should be elevated above the heart and cold compresses applied topically. The facility was clean and very comfortable as was the imaging equipment.

In addition a radiologist at Moffitt from the responsible imaging section should be notified so that the patient can be visited as soon as possible in the Emergency Department. However, the fact that a patient is on dialysis should NOT be regarded as automatically allowing the administration IV contrast. Taken collectively, we can conclude from these studies that intravenous iodinated contrast administration is only rarely associated with acute kidney injury in patients with stable eGFR >30mL/min/1.73mMany patient-specific factors have been proposed as placing patients at risk for CIN. Similarly, performing a CT or radiograph of the extremity for large extravasation is of doubtful utility, other than in cases where the extravasation may be subfascial and may cause a compartment syndrome. ***Prior UCSF recommendations for corticosteroid prophylaxis recommended the use of EITHER methylprednisolone (Solu-Medrol®) OR prednisone to be given 12 and 2 hours prior to imaging studies.

Modulation of the tube current is encouraged in the absence of metallic implants (e.g. Safe intravenous access, for the injection of intravenous contrast, is vital in obtaining high quality contrast enhanced or angiographic studies. However other routes may need to be used and each is considered separately.
