Comparison of the navicular region of newborn foals and adult horses by magnetic resonance imaging.
Abstract: Magnetic resonance imaging (MRI) was tested for evaluation of the soft tissue structures of the equine digit in 16 limbs, derived from three adult warmblood horses and two newborn warmblood foals. The following measuring sequences were used in sagittal, transversal and coronal planes: spin echo, gradient echo, inversion recovery. The images were made with a 1.5 Tesla Siemens scanner in a CP-Helmholtz circular coil. To compare the visualization of the same tissue structures in adult and in newborn cases the limbs were imaged with the routinely used MRI sequences that are used for mature tissues. In newborn foals the bursa podotrochlearis could not be determined with the used sequences. For both the adult and newborn limbs the most visualization of the same tissue structures including the fluid spaces and growth plates were taken by the inversion recovery sequence. T2 sequence was very informative in adult cases but moderately in newborn foals.

This research tested the use of Magnetic Resonance Imaging (MRI) on the soft tissue structures of the equine digit in adult and newborn horses, to compare the visualization of structures and inform future diagnostics in both mature and developing stages.
Objective and Methodology of the Study
- The objective of this study was to comparatively examine the soft tissue structures of the equine digit (a lower limb section) in both adult (mature) horses and newborn foals. The primary tool used for this examination was Magnetic Resonance Imaging (MRI).
- A total of 16 limbs were tested, derived from three adult warmblood horses and two newborn warmblood foals.
- Use of different MRI sequences: The limbs were imaged using a 1.5 Tesla Siemens scanner in a CP-Helmholtz circular coil with multiple MRI sequences, including spin echo, gradient echo, and inversion recovery, oriented in sagittal, transversal, and coronal planes.
Findings and Comparisons
- The researchers compared the images produced by the different sequences in a bid to compare tissue visibility in both adult and newborn horses.
- The study found that for newborn foals, the bursa podotrochlearis (a small, fluid-filled sac in the hoof) could not be detected using the same MRI sequences used for mature tissues.
- Both mature and newborn horse limbs demonstrated most visibility of the same tissue structures, growth plates, and fluid spaces when utilizing the inversion recovery sequence. This suggests that this sequence may be particularly useful for imaging both mature and developing tissues in equines.
- The T2 sequence was found to be highly informative in adult cases, providing clear images of tissue structures. However, it was not as effective in newborn foals, suggesting that different protocols may be needed for imaging younger equine individuals.
Implications
- The findings of the study allow researchers and veterinarians to understand the necessary adaptations required while using MRI for imaging different stages of equine development.
- This information could be instrumental in developing effective detection and diagnostic protocols for both mature and developing horses.
