Abstract<\/h2>\n\n\n\n

Purpose<\/h3>\n\n\n\n

To evaluate the use of magnetic resonance fingerprinting (MRF) for simultaneous quantification of \"urn:x-wiley:07403194:media:mrm28160:mrm28160-math-0005\" and \"urn:x-wiley:07403194:media:mrm28160:mrm28160-math-0006\" in a single breath\u2010hold in the kidneys.<\/p>\n\n\n\n

Methods<\/h3>\n\n\n\n

The proposed kidney MRF sequence was based on MRF echo\u2010planar imaging. Thirty\u2010five measurements per slice and overall 4 slices were measured in 15.4 seconds. Group matching was performed for in\u2010line quantification of \"urn:x-wiley:07403194:media:mrm28160:mrm28160-math-0007\" and \"urn:x-wiley:07403194:media:mrm28160:mrm28160-math-0008\". Images were acquired in a phantom and 8 healthy volunteers in coronal orientation. To evaluate our approach, region of interests were drawn in the kidneys to calculate mean values and standard deviations of the \"urn:x-wiley:07403194:media:mrm28160:mrm28160-math-0009\" and \"urn:x-wiley:07403194:media:mrm28160:mrm28160-math-0010\" times. Precision was calculated across multiple repeated MRF scans. Gaussian filtering is applied on baseline images to improve SNR and match stability.<\/p>\n\n\n\n

Results<\/h3>\n\n\n\n

\"urn:x-wiley:07403194:media:mrm28160:mrm28160-math-0011\" and \"urn:x-wiley:07403194:media:mrm28160:mrm28160-math-0012\" times acquired with MRF in the phantom showed good agreement with reference measurements and conventional mapping methods with deviations of less than 5% for \"urn:x-wiley:07403194:media:mrm28160:mrm28160-math-0013\" and less than 10% for \"urn:x-wiley:07403194:media:mrm28160:mrm28160-math-0014\". Baseline images in vivo were free of artifacts and relaxation times yielded good agreement with conventional methods and literature (deviation \"urn:x-wiley:07403194:media:mrm28160:mrm28160-math-0015\", \"urn:x-wiley:07403194:media:mrm28160:mrm28160-math-0016\").<\/p>\n\n\n\n

Conclusions<\/h3>\n\n\n\n

In this feasibility study, the proposed renal MRF sequence resulted in accurate \"urn:x-wiley:07403194:media:mrm28160:mrm28160-math-0017\" and \"urn:x-wiley:07403194:media:mrm28160:mrm28160-math-0018\" quantification in a single breath\u2010hold.<\/p>\n","protected":false},"featured_media":0,"comment_status":"open","ping_status":"closed","template":"","meta":{"footnotes":""},"categories":[],"class_list":["post-1960","publications","type-publications","status-publish","hentry"],"_links":{"self":[{"href":"https:\/\/www.m2olie.de\/en\/wp-json\/wp\/v2\/publications\/1960","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.m2olie.de\/en\/wp-json\/wp\/v2\/publications"}],"about":[{"href":"https:\/\/www.m2olie.de\/en\/wp-json\/wp\/v2\/types\/publications"}],"replies":[{"embeddable":true,"href":"https:\/\/www.m2olie.de\/en\/wp-json\/wp\/v2\/comments?post=1960"}],"version-history":[{"count":2,"href":"https:\/\/www.m2olie.de\/en\/wp-json\/wp\/v2\/publications\/1960\/revisions"}],"predecessor-version":[{"id":3365,"href":"https:\/\/www.m2olie.de\/en\/wp-json\/wp\/v2\/publications\/1960\/revisions\/3365"}],"wp:attachment":[{"href":"https:\/\/www.m2olie.de\/en\/wp-json\/wp\/v2\/media?parent=1960"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.m2olie.de\/en\/wp-json\/wp\/v2\/categories?post=1960"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
