Spinal angiograms are the pictures obtained when performing spinal angiography. Pictures obtained with conventional spinal angiography differ from those obtained from a CT angiogram of the spine or an MR angiogram of the spine. CT and MR modalities can often be used as screening tools for blood vessel disease but spinal angiography is usually the procedure of choice because MR angiography cannot detect aneurysms below 2-3 mm in size. Routine angiograms are performed in the work up of spinal aneurysms, arteriovenous-malformations, or fistulae and vascular tumors of the spine. Spinal angiography is a fairly lengthy procedure due to the number of vessels that need to be injected. A typical procedure time is 3-4 hours. At the end of the angiogram all catheters are removed and direct pressure is held over the groin puncture until bleeding has stopped. Patients are then closely monitored in a recovery area for 4-6 hours.
