The utility of non\u2010enhanced magnetic resonance imaging (<jats:styled-content style=\"fixed-case\">MRI<\/jats:styled-content>), however, has not been investigated extensively for the diagnosis of <jats:styled-content style=\"fixed-case\">APN<\/jats:styled-content> or renal abscess in children. We describe the case of a 23\u2010month\u2010old boy with suspected <jats:styled-content style=\"fixed-case\">APN<\/jats:styled-content> who received non\u2010enhanced <jats:styled-content style=\"fixed-case\">MRI<\/jats:styled-content>. Whole body diffusion\u2010weighted imaging (<jats:styled-content style=\"fixed-case\">DWI<\/jats:styled-content>) was used, and a background body\u2010signal suppression sequence was applied. High\u2010intensity focal lesions were identified on <jats:styled-content style=\"fixed-case\">DWI<\/jats:styled-content> and low\u2010intensity lesions on the apparent diffusion coefficient map in the acute phase. This case suggested that non\u2010enhanced <jats:styled-content style=\"fixed-case\">MRI<\/jats:styled-content> could be a useful tool for the diagnosis of <jats:styled-content style=\"fixed-case\">APN<\/jats:styled-content> in children, because it can avoid the risks of not only radiation exposure but also nephrogenic systemic fibrosis associated with gadolinium\u2010based contrast agents, especially in infants.<\/jats:p>","DOI":"10.1111\/ped.12312","type":"journal-article","created":{"date-parts":[[2014,6,4]],"date-time":"2014-06-04T03:19:16Z","timestamp":1401851956000},"source":"Crossref","is-referenced-by-count":10,"title":["Utility of non\u2010enhanced magnetic resonance imaging to detect acute pyelonephritis"],"prefix":"10.1111","volume":"56","author":[{"given":"Jun","family":"Aoyagi","sequence":"first","affiliation":[{"name":"Department of Pediatrics Jichi Medical University  Tochigi Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jun","family":"Odaka","sequence":"additional","affiliation":[{"name":"Department of Pediatrics Jichi Medical University  Tochigi Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yuri","family":"Kuroiwa","sequence":"additional","affiliation":[{"name":"Department of Pediatrics Jichi Medical University  Tochigi Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Naomi","family":"Nakashima","sequence":"additional","affiliation":[{"name":"Department of Pediatrics Jichi Medical University  Tochigi Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Takane","family":"Ito","sequence":"additional","affiliation":[{"name":"Department of Pediatrics Jichi Medical University  Tochigi Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Takashi","family":"Saito","sequence":"additional","affiliation":[{"name":"Department of Pediatrics Jichi Medical University  Tochigi Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Takahiro","family":"Kanai","sequence":"additional","affiliation":[{"name":"Department of Pediatrics Jichi Medical University  Tochigi Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Takanori","family":"Yamagata","sequence":"additional","affiliation":[{"name":"Department of Pediatrics Jichi Medical University  Tochigi Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mariko Y","family":"Momoi","sequence":"additional","affiliation":[{"name":"Department of Pediatrics Jichi Medical University  Tochigi Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2014,6,3]]},"reference":[{"key":"e_1_2_5_2_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00330-003-2038-x"},{"key":"e_1_2_5_3_1","first-page":"1252","article-title":"Use of diffusion\u2010weighted MR imaging in differential diagnosis between intracerebral necrotic tumors and cerebral abscesses","volume":"20","author":"Desprechins B","year":"1999","journal-title":"AJNR Am.
