Zero-Echo-Time and Dixon Deep Pseudo-CT (ZeDD CT): Direct Generation of Pseudo-CT Images for Pelvic PET/MRI Attenuation Correction Using Deep Convolutional Neural Networks with Multiparametric MRI
Andrew P. Leynes,Andrew P. Leynes,Jaewon Yang,Florian Wiesinger,Sandeep Kaushik,Dattesh Dayanand Shanbhag,Youngho Seo,Youngho Seo,Thomas A. Hope,Thomas A. Hope,Peder E. Z. Larson,Peder E. Z. Larson +11 more
TL;DR: ZeDD CT produces natural-looking and quantitatively accurate pseudo-CT images and reduces error in pelvic PET/MRI attenuation correction compared with standard methods.
Journal ArticleDOI
Zero TE MR bone imaging in the head.
Florian Wiesinger,Laura Sacolick,Anne Menini,Sandeep Kaushik,Sangtae Ahn,Patrick Veit-Haibach,Gaspar Delso,Gaspar Delso,Dattesh Dayanand Shanbhag +8 more
TL;DR: To investigate proton density‐weighted zero TE (ZT) imaging for morphological depiction and segmentation of cranial bone structures, proton densities are measured through X-ray diffraction and radiolysis.
Journal ArticleDOI
Clinical Evaluation of Zero-Echo-Time MR Imaging for the Segmentation of the Skull
Gaspar Delso,Florian Wiesinger,Laura Sacolick,Sandeep Kaushik,Dattesh Dayanand Shanbhag,Martin Hüllner,Patrick Veit-Haibach +6 more
TL;DR: This is the first, to the authors' knowledge, clinical evaluation of skull bone identification based on a ZTE sequence and the results suggest that proton density–weighted ZTE imaging is an efficient means of obtaining high-resolution maps of bone tissue with sufficient anatomic accuracy for, for example, PET attenuation correction.
Journal ArticleDOI
Comparison of 4-class and continuous fat/water methods for whole-body, MR-based PET attenuation correction
Scott David Wollenweber,Sonal Ambwani,Albert Henry Roger Lonn,Dattesh Dayanand Shanbhag,Sheshadri Thiruvenkadam,Sandeep Kaushik,Rakesh Mullick,Florian Wiesinger,Hua Qian,Gaspar Delso +9 more
TL;DR: It is demonstrated that both 4class and continuousFat/water AC methods provided adequate quantitation in the body, and that the continuous fat/water method was within 5.7% on average for SUV mean in liver and 1.6% onaverage for SUV max for FDG-avid features.
Journal ArticleDOI
Zero TE-based pseudo-CT image conversion in the head and its application in PET/MR attenuation correction and MR-guided radiation therapy planning.
Florian Wiesinger,Mikael Bylund,Jaewon Yang,Sandeep Kaushik,Dattesh Dayanand Shanbhag,Sangtae Ahn,Joakim Jonsson,Josef A. Lundman,Thomas A. Hope,Tufve Nyholm,Tufve Nyholm,Peder E. Z. Larson,C. Cozzini +12 more
TL;DR: A method for converting Zero TE MR images into X‐ray attenuation information in the form of pseudo‐CT images is described and its performance for attenuation correction in PET/MR and dose planning in MR‐guided radiation therapy planning (RTP) is demonstrated.
