To predict blood perfusion in both the diseased femoral head and the transferred bone, all the hips were followed up using dynamic magnetic resonance (MR) scans, performed 1 and 7 months after surgery. In the present cases, it was shown that conventional enhanced MR imaging sometimes depicts increased intensity in bone marrow without blood perfusion due to the leakage of gadolinium\u2010DTPA (Gd\u2010DTPA) from the capillaries surrounding the avascular tissue. It was found that Gd\u2010DTPA remaining in the dead bone marrow resulted in a false\u2010positive image. By contrast, the dynamic MR scan evaluated only those images taken before the leakage. This is one of the advantages of the dynamic study, which reflects actual blood flow in the bone. The fast rise in the time\u2010intensity curve following bolus injection of Gd\u2010DTPA indicates that there is fast blood perfusion in the bone. The dynamic MR scan has demonstrated that there is little blood perfusion in the diseased bone 1 month after the operation and that vascular ingrowth from the transferred bone flap proceeds gradually between 1 and 7 months after surgery. These findings indicate that the dynamic MR scan is very useful in demonstrating vascular ingrowth after surgery in avascular necrosis of the femoral head and can be a reliable monitoring technique for anastomotic patency of the vascularized bone flap. \u00a9 1995 Wiley\u2010Liss, Inc.<\/jats:p>","DOI":"10.1002\/micr.1920161004","type":"journal-article","created":{"date-parts":[[2007,3,4]],"date-time":"2007-03-04T23:42:16Z","timestamp":1173051736000},"page":"673-678","source":"Crossref","is-referenced-by-count":11,"title":["Value of a dynamic MR scan in predicting vascular ingrowth from free vascularized scapular transplant used for treatment of avascular femoral head necrosis"],"prefix":"10.1002","volume":"16","author":[{"given":"Kohzou","family":"Fujisawa","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hitoshi","family":"Hirata","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hitoshi","family":"Inada","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Akimasa","family":"Morita","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kan","family":"Takeda","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hiroshige","family":"Hibasami","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2005,10,19]]},"reference":[{"key":"e_1_2_1_2_2","first-page":"178","volume-title":"Microsurgery for major limb reconstruction","author":"Urbaniak JR","year":"1987"},{"key":"e_1_2_1_3_2","doi-asserted-by":"publisher","DOI":"10.1148\/radiology.169.2.3175001"},{"key":"e_1_2_1_4_2","doi-asserted-by":"publisher","DOI":"10.1148\/radiology.182.2.1732963"},{"key":"e_1_2_1_5_2","doi-asserted-by":"publisher","DOI":"10.1148\/radiology.176.2.2367649"},{"key":"e_1_2_1_6_2","doi-asserted-by":"publisher","DOI":"10.1148\/radiology.193.1.8090922"},{"key":"e_1_2_1_7_2","first-page":"275","article-title":"Bone marrow perfusion evaluated with gadolinium\u2010enhanced dynamic fast MR imaging in a dog model","volume":"27","author":"Cova M","year":"1992","journal-title":"Radiology"},{"key":"e_1_2_1_8_2","doi-asserted-by":"publisher","DOI":"10.1097\/00004424-199204000-00002"},{"key":"e_1_2_1_9_2","first-page":"103","article-title":"MRI appearance of femoral head osteonecrosis following core decompression and bone grafting","volume":"20","author":"Chen TW","year":"1991","journal-title":"Skeletal Radiol"},{"key":"e_1_2_1_10_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0009-9260(05)81884-7"},{"key":"e_1_2_1_11_2","first-page":"715","volume-title":"Microsurgery: Transplantation\u2010Replantation","author":"Buncke HJ","year":"1991"},{"key":"e_1_2_1_12_2","doi-asserted-by":"publisher","DOI":"10.1002\/micr.1920151107"},{"key":"e_1_2_1_13_2","doi-asserted-by":"crossref","first-page":"123","DOI":"10.1302\/0301-620X.75B1.8421008","article-title":"Vascularized fibular grafts for reconstruction of the femur","volume":"75","author":"Yajima H","year":"1993","journal-title":"J Bone Joint Surg"},{"key":"e_1_2_1_14_2","first-page":"400","article-title":"Evaluation of blood perfusion in vascularized bone graft by dynamic MRI (in Japanese)","volume":"27","author":"Beppu M","year":"1992","journal-title":"Transplantation"}],"container-title":["Microsurgery"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/api.wiley.com\/onlinelibrary\/tdm\/v1\/articles\/10.1002%2Fmicr.1920161004","content-type":"unspecified","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1002\/micr.1920161004","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2023,10,25]],"date-time":"2023-10-25T13:47:24Z","timestamp":1698241644000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1002\/micr.1920161004"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[1995,1]]},"references-count":13,"journal-issue":{"issue":"10","published-print":{"date-parts":[[1995,1]]}},"alternative-id":["10.1002\/micr.1920161004"],"URL":"https:\/\/doi.org\/10.1002\/micr.1920161004","archive":["Portico"],"relation":{},"ISSN":["0738-1085","1098-2752"],"issn-type":[{"value":"0738-1085","type":"print"},{"value":"1098-2752","type":"electronic"}],"subject":[],"published":{"date-parts":[[1995,1]]}}}
