Contrast-enhanced CT images depicted all osseous borders; MR images were superior for soft tissue structures.ConclusionsThis study enhances the understanding of normal cervical spine anatomy and the diagnostic usefulness of cervical MRI and contrast-enhanced CT in the horse.Ethical animal researchThis ...
Forum (2) Inhomogeneityis the degree of lack ofhomogeneity, for example the fractional deviation of the localmagnetic fieldfrom the average value of the field. Inhomogeneities of the staticmagnetic field, produced by the scanner as well as by objectsusceptibility, is unavoidable inMRI. The large ...
Conclusions This study enhances the understanding of normal cervical spine anatomy and the diagnostic usefulness of cervical MRI and contrast‐enhanced CT in the horse. Ethical animal research This study was approved by the animal care and use committee of the M ississippi S tate U niversity, MS...
MRI velocimetry (also known as phase-contrast MRI) is a powerful tool for quantification of cerebrospinal fluid (CSF) flow in various regions of the brain and craniospinal junction and has been accepted as a diagnostic tool to assist with the diagnosis of certain conditions such as hydrocephalus...
Sleutjens J, Cooley AJ, Sampson SN, et al. The equine cervical spine: comparing MRI and contrast-enhanced CT images with anatomic slices in the sagittal, dorsal, and transverse plane. Vet Q 2014;34:74-84.Sleutjens, J., Cooley, A.J., Sampson, S.N., Wijnberg, I.D., Back, W.,...
Objectives: (1) To describe in detail the anatomy of the equine cervical spine by comparing anatomical sections with corresponding MR and contrast-enhanced CT images in the sagittal, dorsal, and transverse plane. (2) To discuss the ability of MR and contrast-enhanced CT imaging to visualize ...
Crosstalk is anartifactintroduced into images byinterferencebetween adjacent slices of a scan, caused by aslice profilethat is not ideal due to the constraints of the measurement technology. If theslicedistances are too small, there is cross talk between the slices, which can affect T1contrast. ...
The aorta is conventionally selected for AIF parameter estimation in the spine. However, there is a fundamental problem with this approach as ET assumes that the arterial contrast signal intensity curve is simultaneous to contrast uptake in vertebral body lesions. In fact, the bone marrow is much...
Zhong et al. [22] proposed an MRI-based radiomics nomogram to differentiate cervical spine osteoradionecrosis from metastasis in patients with nasopharyngeal carcinoma after radiotherapy. The nomogram model demonstrated good calibration and discrimination, and DCA indicated that, if the threshold probability...
respectively. As for contrast-enhanced images, accuracy of 95.62%, recall of 80.72%, precision of 94.24%, and an F1-score of 86.96% were attained. Conclusions: Based on the results, the proposed method for classifying AS disease has demonstrated successful outcomes using MRI. The model has bee...
