Brain volume estimation from post-mortem newborn and fetal MRI
OBJECTIVE Minimally invasive autopsy using post-mortem magnetic resonance imaging (MRI) is a valid alternative to conventional autopsy in fetuses and infants. Estimation of brain weight is an integral part of autopsy, but manual segmentation of organ volumes on MRI is labor intensive and prone to errors, therefore unsuitable for routine clinical practice. In this paper we aim to show that volum...
متن کاملPartial Volume Estimation in Brain MRI Revisited
We propose a fast algorithm to estimate brain tissue concentrations from conventional T1-weighted images based on a Bayesian maximum a posteriori formulation that extends the "mixel" model developed in the 90's. A key observation is the necessity to incorporate additional prior constraints to the "mixel" model for the estimation of plausible concentration maps. Experiments on the ADNI standardi...
متن کاملcomparison of prostate and bladder volume measurements from mri and pre- and post-mri ultrasound images
background : safe dose escalation is highly desirable in radiotherapy for prostate cancer. prostate displacement due to bladder filling can be significant, so improved targeting of the prostate by ultrasound imaging potentially allows for a reduction in the target margin and consequently less toxicity. this study estimates the accuracy of ultrasound for prostate and bladder volume measurements ...
متن کاملSnapshot MRI with volume reconstruction of the fetal brain
Introduction: Fetal magnetic resonance imaging (MRI) is able to increase the detection of abnormalities within the fetal brain and to improve their characterisation when compared with antenatal ultrasound. The most frequent indications for referral for MRI include ventriculomegaly, abnormal appearance to the cerebellar vermis or suspected commissural agenesis. Fetal imaging provides information...
متن کاملFetal Adrenal Gland in the Second Half of Gestation: Morphometrical Assessment with 3.0T Post-Mortem MRI
BACKGROUND The morphometry of fetal adrenal gland is rarely described with MRI of high magnetic field. The purpose of this study is to assess the normal fetal adrenal gland length (AL), width (AW), height (AH), surface area (AS) and volume (AV) in the second half of gestation with 3.0T post-mortem MRI. METHODS AND FINDINGS Fifty-two fetal specimens of 23-40 weeks gestational age (GA) were sca...
