The rate at which ROCM must be injected to achieve a high iodine concentration depends on several factors, including the desired concentration, the volume of the bloodstream, and the rate of clearance of iodine from the body. In general, a higher injection rate would result in a higher concentration of iodine in the bloodstream. However, it is important to note that the injection rate should be determined by a medical professional based on the specific needs and circumstances of the patient.
