What coagulation cutoff parameters do you use for invasive radiological prodedures?
In general, platelets > 100, PT/INR > 1.5, and PTT > 45. These parameters may be modified on a case by case basis at the radiologist’s discretion. Which types of intravenous acess are suitable for the administration of contrast materials? For most contrast-enhanced CT and MR exams, a 22-gauge or larger IV is preferable, but a 24 gauge IV may be adequate for hand injections. For CT angiography exams (e.g. rule out PE, peripheral runoffs), as well as multiphase CT exams (e.g. liver and pancreas protocol exams), an 18-gauge IV is preferred given the higher injection rates of contrast. Tunneled catheters and PICC’s are in general not approved for power injector use. However, Power Port’s and Power PICC’s manufactured by Bard are approved for use with power injectors. If you are interested in these products, you should consult with the surgeon or intravenous therapy team at your institution regarding their availability. 16.

In general, platelets greater than 100, PT/INR of less than 1.5 are needed to proceed with an invasive procedure. Of note; PTT is no longer needed to be checked.
