Intravenous urograms (IVUs) have been performed routinely to screen potential donors at the Veterinary Hospital of the University of Pennsylvania (VHUP), but the vascular phase views lack sufficient detail of the renal vascular anatomy. Computed tomography angiography (CTA), which requires a helical computed tomography (CT) scanner, has been found to provide superior renal vascular anatomic information of prospective human renal donors. The specific aims of this study were as follows: 1) develop the CTA technique for the feline patient; and 2) obtain preliminary information on feline renal vessel anatomy in potential renal donors. Ten healthy, potential feline renal donors were anesthetized and imaged using a third\u2010generation helical CT scanner. The time delay between IV contrast medium injection and image acquisition, and other parameters of slice collimation, slice interval, pitch, exposure settings, and reconstruction algorithms were varied to maximize contrast medium opacification of the renal vascular anatomy. Optimal CTA acquisition parameters were determined to be: 1) 10\u2010sec delay post\u2010IV bolus of iodinated contrast medium; 2) two serially acquired (corresponding to arterial and venous phases) helical scans through the renal vasculature; 3) pitch of 2 (4 mm\/sec patient translation, 2 mm slice collimation); and 4) 120\u2010kVp, 160\u2010mA, and 1\u2010sec exposure settings. Retrospective reconstructed CTA transverse images obtained at a 2\u2010nim slice width and a 1\u2010mm slice interval in combination with two\u2010dimensional reformatted images and three\u2010dimensional reconstructed images were qualitatively evaluated for vascular anatomy; vascular anatomy was confirmed at surgery. Four cats had single renal arteries and veins bilaterally; four cats had double renal veins. One cat had a small accessory artery supplying the caudal pole of the left kidney. One cat had a left renal artery originating from the aorta at a 90\u00b0 angle with the cranial mesenteric artery. CTA of the feline renal vascular anatomy is feasible, and reconstruction techniques provide excellent anatomic vascular detail. CTA is now used routinely at VHUP to screen all potential feline renal donors.<\/jats:p>","DOI":"10.1111\/j.1740-8261.2003.tb00522.x","type":"journal-article","created":{"date-parts":[[2005,5,19]],"date-time":"2005-05-19T16:26:08Z","timestamp":1116519968000},"page":"636-641","source":"Crossref","is-referenced-by-count":30,"title":["USE OF COMPUTED TOMOGRAPHY RENAL ANGIOGRAPHY FOR SCREENING FELINE RENAL TRANSPLANT DONORS"],"prefix":"10.1111","volume":"44","author":[{"given":"Jennifer L.","family":"Bouma","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lillian R.","family":"Aronson","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Dennis G.","family":"Keith","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"H.","family":"Mark Saunders","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2005,5,19]]},"reference":[{"key":"e_1_2_1_2_2","first-page":"336","article-title":"Clinical renal transplantation in the cat: a review of 23 cases","volume":"20","author":"Gregory CR","year":"1991","journal-title":"Vet Surg"},{"key":"e_1_2_1_3_2","doi-asserted-by":"crossref","first-page":"285","DOI":"10.2460\/javma.1992.201.02.285","article-title":"Renal transplantation for treatment of end\u2010stage renal failure in cats","volume":"201","author":"Gregory CR","year":"1992","journal-title":"J Am Vet Med Assoc"},{"key":"e_1_2_1_4_2","first-page":"1141","volume-title":"Textbook of small animal surgery","author":"Slatter D.","year":"1993"},{"key":"e_1_2_1_5_2","first-page":"261","article-title":"Angiographic assessment of potential renal transplant donors","volume":"25","author":"Derauf B","year":"1987","journal-title":"Radiol Clin North Am"},{"key":"e_1_2_1_6_2","doi-asserted-by":"publisher","DOI":"10.1148\/radiology.195.2.7724766"},{"key":"e_1_2_1_7_2","doi-asserted-by":"publisher","DOI":"10.1148\/radiographics.18.3.9599383"},{"key":"e_1_2_1_8_2","doi-asserted-by":"publisher","DOI":"10.2214\/ajr.168.6.9168727"},{"key":"e_1_2_1_9_2","doi-asserted-by":"publisher","DOI":"10.2214\/ajr.169.5.9353451"},{"key":"e_1_2_1_10_2","doi-asserted-by":"publisher","DOI":"10.1148\/radiology.198.2.8596843"},{"key":"e_1_2_1_11_2","doi-asserted-by":"publisher","DOI":"10.1097\/00007890-199502270-00037"},{"key":"e_1_2_1_12_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0041-1345(00)01321-X"},{"key":"e_1_2_1_13_2","doi-asserted-by":"publisher","DOI":"10.1034\/j.1399-0012.1999.130107.x"},{"key":"e_1_2_1_14_2","doi-asserted-by":"publisher","DOI":"10.1046\/j.1440-1622.1999.01526.x"},{"key":"e_1_2_1_15_2","doi-asserted-by":"crossref","first-page":"51","DOI":"10.1016\/S0033-8389(22)00562-0","article-title":"Current status of three\u2010dimensional spiral CT scanning for imaging the vasculature","volume":"33","author":"Rubin GD","year":"1995","journal-title":"Radiol Clin North Am"},{"key":"e_1_2_1_16_2","doi-asserted-by":"publisher","DOI":"10.1148\/radiographics.21.2.g01mr19373"}],"container-title":["Veterinary Radiology &amp; Ultrasound"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/api.wiley.com\/onlinelibrary\/tdm\/v1\/articles\/10.1111%2Fj.1740-8261.2003.tb00522.x","content-type":"unspecified","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1111\/j.1740-8261.2003.tb00522.x","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2024,1,26]],"date-time":"2024-01-26T01:29:01Z","timestamp":1706232541000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1111\/j.1740-8261.2003.tb00522.x"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2003,11]]},"references-count":15,"journal-issue":{"issue":"6","published-print":{"date-parts":[[2003,11]]}},"alternative-id":["10.1111\/j.1740-8261.2003.tb00522.x"],"URL":"https:\/\/doi.org\/10.1111\/j.1740-8261.2003.tb00522.x","archive":["Portico"],"relation":{},"ISSN":["1058-8183","1740-8261"],"issn-type":[{"value":"1058-8183","type":"print"},{"value":"1740-8261","type":"electronic"}],"subject":[],"published":{"date-parts":[[2003,11]]}}}
