In those studies that have addressed chronic rejection, there is agreement that changes in renal function are not accompanied by consistent changes in flow wave\u2010form shape. The pathology of chronic rejection may be very different from the changes seen in acute rejection and its onset is usually gradual. Some authors have suggested that the decline in function is accompanied by lower Doppler frequency shifts (corresponding to lower velocities) in intra\u2010renal arteries. In a preliminary study comparing grafts with normal renal function and with biopsy\u2010proven chronic rejection, it has been shown that for grafts with chronic rejection, observed intra\u2010renal velocities are lower, especially at segmental and interlobar levels. This may be a more reliable reflection of reduced renal blood flow in chronic rejection than conventional Doppler ultrasound analysis of flow waveform shape. However, the diagnostic use of changes to intra\u2010renal flow velocities in chronic rejection is currently very limited. \u00a9 1992 John Wiley &amp; Sons, Inc.<\/jats:p>","DOI":"10.1002\/jcu.1870200807","type":"journal-article","created":{"date-parts":[[2007,2,28]],"date-time":"2007-02-28T20:46:14Z","timestamp":1172695574000},"page":"539-544","source":"Crossref","is-referenced-by-count":10,"title":["Doppler and color Doppler ultrasonography in renal transplants: Chronic rejection"],"prefix":"10.1002","volume":"20","author":[{"given":"Colin","family":"Deane","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2005,12,2]]},"reference":[{"key":"e_1_2_1_2_2","first-page":"184","volume-title":"Concise Renal Pathology","author":"Dische FE","year":"1987"},{"key":"e_1_2_1_3_2","first-page":"1941","volume-title":"The Kidney","author":"Strom TB","year":"1985"},{"key":"e_1_2_1_4_2","doi-asserted-by":"publisher","DOI":"10.1016\/0090-4295(82)90195-9"},{"key":"e_1_2_1_5_2","doi-asserted-by":"publisher","DOI":"10.2214\/ajr.149.3.521"},{"key":"e_1_2_1_6_2","doi-asserted-by":"publisher","DOI":"10.1148\/radiology.162.1.3538151"},{"key":"e_1_2_1_7_2","first-page":"1893","article-title":"Duplex Doppler evaluation of renal allograft dysfunction","volume":"21","author":"Marchal G","year":"1989","journal-title":"Trans Procs"},{"key":"e_1_2_1_8_2","doi-asserted-by":"publisher","DOI":"10.2214\/ajr.152.3.535"},{"key":"e_1_2_1_9_2","doi-asserted-by":"publisher","DOI":"10.1148\/radiology.171.3.2655003"},{"key":"e_1_2_1_10_2","doi-asserted-by":"publisher","DOI":"10.1177\/000331978904000804"},{"key":"e_1_2_1_11_2","doi-asserted-by":"publisher","DOI":"10.7863\/jum.1990.9.4.199"},{"key":"e_1_2_1_12_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0272-6386(12)80524-5"},{"key":"e_1_2_1_13_2","doi-asserted-by":"publisher","DOI":"10.2214\/ajr.155.3.2117350"},{"key":"e_1_2_1_14_2","doi-asserted-by":"publisher","DOI":"10.2214\/ajr.155.3.2117351"},{"key":"e_1_2_1_15_2","volume-title":"Arteries","author":"McDonald DA","year":"1974"},{"key":"e_1_2_1_16_2","volume-title":"The Mechanics of the Circulation","author":"Caro CG","year":"1978"},{"key":"e_1_2_1_17_2","volume-title":"Hemodynamics","author":"Milnor WR","year":"1982"},{"key":"e_1_2_1_18_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0009-9260(05)81651-4"},{"key":"e_1_2_1_19_2","doi-asserted-by":"publisher","DOI":"10.1002\/jcu.1870150904"},{"key":"e_1_2_1_20_2","doi-asserted-by":"publisher","DOI":"10.1016\/0720-048X(90)90139-3"},{"key":"e_1_2_1_21_2","first-page":"1919","article-title":"Renal transplant blood flow evaluation by color Doppler echography","volume":"21","author":"Nishioka T","year":"1989","journal-title":"Trans Proc"},{"key":"e_1_2_1_22_2","volume-title":"Doppler Ultrasound.
