Abdominal CTA With Direct Dual Energy Bone Subtraction

September 18, 2008 Abdominal CTA With Direct Dual Energy Bone Subtraction -------------------------------------------------------------------------------- HISTORY A 75-year-old man was referred for presurgical MDCT evaluation of a known abdominal aortic aneurysm that had been detected on screening abdominal ultrasound. A contrast enhanced CTA scan of the abdomen was performed. DIAGNOSIS The acquisition parameters allowed precise localization of the origin of the aneurysm with respect to the renal arteries and allowed for necessary measurements of the neck of the aneurysm, the distance from the renal arteries to the aortic bifurcation and to each common iliac bifurcation to be calculated, and the adequacy of the run-off to the lower extremities to be assessed. Finally, a small accessory renal artery supplying the upper pole of the right kidney was detected. Based on this single study, the patient was considered a candidate for endovascular repair.
