DOI: 10.1016/j.clinimag.2020.06.040
Abstract: Contrast media administration has been associated with complications such as nephropathy, cardiovascular morbidity, and neurovascular events, particularly in patients with renal insufficiency. This association has been questioned in recent studies. This review was performed to… read more here.
