Standing cone‐beam computed tomographic digital flexor tendon sheath contrast tenography in 18 horses Open
Summary Background Limited data exist on the benefits of using standing cone‐beam computed tomography (CBCT) contrast tenography before tenoscopy of the digital flexor tendon sheath (DFTS). Objectives To document DFTS pathologies in a samp…
Computed Tomographic Tenography of the Equine Carpal Flexor Tendon Sheath Open
Exploratory tenoscopy is considered the gold standard technique to identify intrathecal pathology of the equine carpal flexor tendon sheath (CFTS). Preoperative diagnosis allows for more precise prognostication and surgical planning, poten…
Imaging and histopathological findings of a third metacarpal aneurysmal bone cyst and pathological proximal suspensory ligament avulsion fracture Open
Summary A 10‐year‐old Quarter Horse mare presented with acute and severe lameness, persisting despite initial farriery intervention. Upon physical examination, palpation of the proximal thirds of the third and fourth metacarpal bones elici…
Computed tomographic cervical myelography in horses: Technique and findings in 51 clinical cases Open
Background Three‐dimensional computed tomographic (CT) evaluation of the cervical vertebral column enables more accurate identification of osseous and soft tissue lesions than traditional latero‐lateral radiography. However, examination of…
Risk of intra-articular injection with longitudinal ultrasound-guided injection of the collateral ligaments of the distal interphalangeal joint in the horse Open
Desmopathy of the collateral ligaments of the distal interphalangeal joint is a common cause of equine foot lameness and carries a poor prognosis with conservative management. Intralesional injections may improve healing, although accuracy…

Desmopathy of the collateral ligaments of the distal interphalangeal joint is a common cause of equine foot lameness and carries a poor prognosis with conservative management. Intralesional injections may improve healing, although accuracy…
Use of positive contrast radiography to identify synovial involvement in horses with traumatic limb wounds Open
Summary Background The diagnostic value of positive contrast radiography in the work‐up of suspected synovial infection in horses with limb wounds near synovial structures has yet to be systematically evaluated. Objectives To determine the…
Is There An Association Between Straight Tarsus (Hock) Conformation and Hindlimb Proximal Suspensory Desmopathy? Open
Reasons for performing study: Presurgical investigation of digital flexor tendon sheath (DFTS) pathology is challenging, driving a need for increasingly sensitive and specific diagnostic tools.Computed tomographic contrast tenography (cCT)…
Skeletal pathology and variable anatomy in elephant feet assessed using computed tomography Open
Foot problems are a major cause of morbidity and mortality in elephants, but are underreported due to difficulties in diagnosis, particularly of conditions affecting the bones and internal structures. Here we evaluate post-mortem computer …
Peer Review #1 of "Skeletal pathology and variable anatomy in elephant feet assessed using computed tomography (v0.1)" Open
Foot problems are a major cause of morbidity and mortality in elephants, but are underreported due to difficulties in diagnosis, particularly of conditions affecting the bones and internal structures.Here we evaluate post-mortem computer t…
Clinical application of multidetector computed tomography and magnetic resonance imaging for evaluation of cranial nerves in horses in comparison with high resolution imaging standards Open
Summary Although horses are affected by cranial nerve disease, our understanding of these structures' imaging anatomy is limited, and the optimal modality for imaging of each of these nerves is unclear. The aim of this study was to describ…

Common artefacts and pitfalls in equine computed and digital radiography and how to avoid them Open
Summary Radiographic technology has rapidly advanced over the last decade with the use of both computed radiography and digital radiography now being common in equine practice. Image quality is critical for optimal diagnostic accuracy, so …
IMAGING DIAGNOSIS—IDIOPATHIC HYOID MALFORMATION IN AN 8‐YEAR‐OLD WELSH SECTION D HORSE Open
An 8‐year‐old gelding was evaluated for intermittent dorsal displacement of the soft palate (DDSP) at exercise. Standing laterolateral radiographs demonstrated an abnormal crossed appearance of the stylohyoid bones. Computed tomography (CT…
Technical innovation changes standard radiographic protocols in veterinary medicine: is it necessary to obtain two dorsoproximal–palmarodistal oblique views of the equine foot when using computerised radiography systems? Open
Since the 1950s, veterinary practitioners have included two separate dorsoproximal–palmarodistal oblique (DPr–PaDiO) radiographs as part of a standard series of the equine foot. One image is obtained to visualise the distal phalanx and the…
COMPUTED TOMOGRAPHIC APPEARANCE OF MELANOMAS IN THE EQUINE HEAD: 13 CASES Open
Melanomas are one of the most common neoplasms in the horse and are frequently found in the head region. There is a genetic predisposition in horses with a gray hair coat. Computed tomography (CT) is frequently used in referral practice to…
