Answer

Patients with a history of severe reactions to IV radiocontrast media may require use of contrast in an urgent or emergency situation. Alternatives (eg, noncontrast spiral computed tomography [CT] for ureteral stone, Doppler ultrasonography for deep venous thrombosis [DVT], nuclear scans or spiral CT for pulmonary embolism) should be considered but are not always feasible. In these circumstances, a prophylactic regimen of corticosteroids and antihistamines may be used.
