The bregmatic fontanelle alone is an unreliable indicator of health in Pomeranian and other toy-sized dogs.

The Swiss Animal Welfare Ordinance prohibits the breeding of dogs with persistent fontanelles. Especially in toy-sized dogs, closed fontanelles are important for breeding selection. In such dogs, other alterations at the cranio-cervical junction, hydrocephalus and syringomyelia are frequently observed in magnetic resonance imaging (MRI).

Non-contrast enhanced visualization of the equine foot vasculature in a cadaver model using time-of-flight sequence.

Objective: The objective of this study was to establish a non-contrast enhanced MR angiography (NC-MRA) sequence for the equine foot (EF) using a post-mortem angiography model.

Materials And Methods: Time-of-flight (TOF) sequences were tested using variable parameter settings and 3 slice orientations during vascular perfusion of frozen-thawed cadaver EF with paraffine oil. Transverse and dorsal orientations were planned perpendicular or parallel to the sublamellar vascular plexus at the dorsal aspect of P3, or approximately perpendicular to the coronary plexus.

Pulse-Echo Imaging of Breast Speed of Sound as a Potential Biomarker for Breast Cancer.

Objective: Speed-of-sound (SoS) images, derived from minute misalignments between ultrasound images consecutively acquired using a motion-robust technique, were studied with multi-frame acquisitions to derive a lesion assessment metric for the differential diagnosis of breast cancer.

Methods: SoS elevation within inclusions was characterized as SoS contrast by comparing inclusions with their surrounding tissue. Malignancy was predicted as having larger SoS contrast compared with benign inclusions.

Uncertainty estimation for trust attribution to speed-of-sound reconstruction with variational networks.

Purpose: Speed-of-sound (SoS) is a biomechanical characteristic of tissue, and its imaging can provide a promising biomarker for diagnosis. Reconstructing SoS images from ultrasound acquisitions can be cast as a limited-angle computed-tomography problem, with variational networks being a promising model-based deep learning solution. Some acquired data frames may, however, get corrupted by noise due to, e.

A Dorsal Intramedullary T2-Weighted Hypointense Signal Suggests Haemorrhagic Necrotic Material Indicating Ascending-Descending Myelomalacia in Dogs.

Background: Ascending-descending myelomalacia (ADMM) is a progressive softening of the spinal cord observed in dogs after spinal cord injury (SCI). On histopathology, areas of hemorrhagic necrotic material are found in the central canal and dorsal funiculi.

Hypothesis/objectives: We investigated if hemorrhagic necrotic material dorsal to the central canal can be identified on magnetic resonance imaging (MRI).
