It’s been quite a year for Hallmarq’s Vision CT. Designed to bring fast 3D imaging to every equine practice, the walk-in-scan-walk-out system is safe, effective, and affordable. It offers the next step up from DR and is proving particularly effective when used in combination with our Standing Equine MRI. In a series of studies undertaken on Thoroughbred cadaver limbs using Vision CT, fan beam CT, and MRI, we take the opportunity to pull together this year’s published papers:

Sagittal and parasagittal groove fissures

Fractures of the third metacarpal/tarsal parasagittal groove and proximal phalanx sagittal groove are common in racehorses. It is important to detect precursor pathologies including fissures to prevent the propagation to fracture. This study aims to identify the imaging features and compare the diagnosis of fissures on cone-beam (CB) computed tomography (CT), fan-beam (FB) CT, and low-field magnetic resonance imaging (MRI) to histopathology associated with fissures.

Palmar osteochondral disease

Palmar/plantar osteochondral disease (POD) of the metacarpal/tarsal condyles is a common pathological finding in racehorses. This cross-sectional study compares diagnoses, imaging details, and measurements of POD lesions between cone-beam computed tomography CT (CBCT), fan-beam CT (FBCT), and low-field magnetic resonance imaging (MRI) using macroscopic pathology as a gold standard. Thirty-five cadaver limbs from 10 horses underwent CBCT, FBCT, MRI, and macroscopic examination. CT and MR images were examined for the presence of POD, imaging details of POD, and measurements of POD dimensions and areas. Imaging diagnoses, details, and measurements were compared with macroscopic examination and between modalities.

Heterotopic mineralisation

Heterotopic mineralization in equine distal limbs has been considered an incidental finding and little is known about its imaging features. The study aimed to identify heterotopic mineralization and adjacent pathology in the fetlock region with cone-beam (CB) computed tomography (CT), fan-beam (FB) CT, and low-field magnetic resonance imaging (MRI). Images from 12 equine cadaver limbs were examined for heterotopic mineralization and adjacent pathology and verified by macro-examination.

Fig. 1. Focal mineralization at the insertion of the suspensory ligament branches (Fetlock 2). CBCT standard (A) and bone (B) windows and the FBCT standard (C) and soft tissue (D) windows. The homogenous, hyper-attenuated mineralizations (arrows) were most evident on the standard and bone windows of the CBCT images and the soft tissue window of the FBCT image. Lateral is to the left.

Proximal phalanx dorsoproximnal osteochondral defects

Osteochondral defects in the dorsoproximal aspect of the proximal phalanx, including the dorsomedial and dorsolateral eminences, are a common pathology affecting the metacarpophalangeal/metatarsophalangeal (fetlock) joint in horses. Dorsoproximal osteochondral defects commonly affect the proximal phalanx, but information about diagnosis on computed tomography (CT) and magnetic resonance imaging (MRI) is limited. This cross-sectional study assesses CT and MRI diagnoses of osteochondral defects, describes the lesions, and compares the sensitivity and specificity of the modalities using macroscopic pathology as the gold standard.
