Case 1
The same 60-minute was seen earlier in this lecture. On the left no abnormal activity is noted. On the right the lower GI track is transposed over the same image, showing where the colon is located. Additionally note the following vascular structures: heart, liver, spleen, and descending aorta.
Case 2
This patient had a multitude of health problems, which include: CHF, hx of pulmonary emboli, cirrhosis, atria fibrillation, venous stasis, occult stool. It should also be noted that a vena cava filter was placed in the patient 13 yrs ago to filter our pulmonary emboli. Images of the lower abdomen were taken every five to ten minutes for 55 minutes. Results indicated that there was no indication of a bleeding site. However, the unusual finding is the varices noted the lower abdomen, sometimes refereed to as caput medusae. This was caused by vena cava filter.
Case 3
Following the injection of labeled RBCs a "blush" of activity was soon noted in the ascending colon. Four images displayed demonstrate the rapid movement of blood in the GI track as it moves from the ascending to the distal end of the transverse colon.
Case 4
This is a 53 year old male that had was excreting large purple clots. Tagged RBCs are noted early during imaging and is initiated within the small intestine. Clicking the image will show an enlarged view of the image.
