3. This is the raw image seen in the previous slide (#1) before it was subtracted. This process, known as digital subtraction angiography (DSA) attempts to remove all densities except those in the range of the iodine contrast in the arteries. Notice the bones of the pelvis and spine seen on this image are not seen on image 1. Bowel gas is seen due to motion. The success of this process is dependant on there being no motion between an image taken before contrast injection, (the mask image) and the contrast film. Several seconds may pass between them, and areas of motion create subtraction artifacts. Radiographs vs. DSA

Abdominal aorta * Compare the origin of this vessel, from the abdominal aorta, to the variation labeled “B” on plate (324) 333 This injection of the abdominal aorta is unusual. Typically the aorta fills instantly, and the renals and SMA fill momentarily, or sometimes not well at all (notice the lack of filling of the SMA on image 2). In this case the position of the catheter and the sideholes were such that everything but a small portion of the aorta were filled at the moment the image was made. Bilateral renal arteriogram

7. 1. Common hepatic artery 2. Gastroduodenal artery 3. Hepatic artery proper 4. Rt hepatic artery 5. Lt hepatic artery On this injection the catheter tip was advanced to the common hepatic artery. On Netter’s plate (293) 303, the catheter tip is in the celiac trunk. Notice the filling of the splenic and Lt gastric artery as well. Due to its small size and position at the proximal part of the trunk the Lt gastric does not always fill on a celiac injection. Selective Hepatic Plates (290-293) 300-302

22. 1. Rt femoral vein 2. Rt popliteal vein The proliferation of veins below the head of the fibula are superficial. They disappear so dramatically due to a tourniquet at that level. Prior to vascular ultrasound venograms were the “gold standard” for visualizing deep vein thrombosis (DVT). The injection was made through a superficial vein in the dorsum of the foot, and tourniquets at the ankle, below the knee, and on the distal thigh helped drive the iodine contrast into the deep system. Finding a vein in edematous tissue was a challenge, and filling the deep venous system was a tricky and exacting process, and most uncomfortable for the patient. There are undoubtedly few, if any, radiologic technologists who are not thankful that vascular ultrasound has supplanted there need to perform this exam. #19 Rt leg venogram Plates (498, 526-528) 502, 516-517
