“…Different ultrasonographic scoring systems have been previously used to semi-quantitatively evaluate injured tendons in veterinary practice (Genovese et al 1986;Saini et al 2002;Van den Belt et al 1993). In the present study, four semiquantitative ultrasonographic criteria were defined (score 0 -4): a. lesion echogenicity (0 sane echogenic tissue -4 pathologic anechogenic tissue), b. transversal lesion extent (0 no extension -4 lesion area > 50% of the cross-sectional area), c. transversal lesion architecture (0 normal -4 pathologic hypoechogenic tissue) and d. longitudinal lesion architecture (0 sane tendon -4 complete disorganization of fibres pattern).…”

“…They often require long periods without full training and they represent one of the major reasons of horse athletes retirement (Lam et al 2007). Ultrasonography is a widely spread technique for tendon lesions diagnosis, follow-up and a tool to establish a prognosis (Denoix et al 1990;Genovese et al 1986). Although qualitative in nature, the signs characterizing the ultrasonographic images of a tendon lesion (e.g.…”

“…Ultrasonographic evaluation described by Tnibar et al 1999 using a linear 7,5 MHz transducer, revealed the presence of an irregular anechoic area between zones B and C of the biceps tendon, characterizing grade 2/4 of fibers rupture [1 = slightly (25%) less echogenic than normal, 2 = half echogenic and half anechoic, 3 = mostly anechoic (75%) 4 = completely anechoic, Genovese et al 1986] (Figures 1a and 1c). Areas of mineralization, which can occur in chronic cases, were not observed (Boys Smith et al 2007).…”

“…The upper zone, 1A, included the 4 cm immediately distal to the base of the accessory carpal bone. The next zone, 1B, was the 4 cm below zone 1A, and so on, proceeding through zones 2A, 2B, 3A and 3B [5]. In the antemortem specimens, 6 of the transverse slices fitted the ultrasound positions, with the addition of 1A, 1B-2A, 2B-3A and below 3B (3C) slices, to make a total of 10.…”

ABSTRACT. In this study antemortem evaluation of equine flexor tendons -the superficial digital flexor tendon and the deep digital flexor tendon -using magnetic resonance (MR) images was performed. Postmortem flexor tendons were used to prepare the slice positions, coil and body positions for MR imaging. It was possible by this method to take antemortem MR images of equine limbs that distinguished features as well as postmortem images described in previous studies. The total time of antemortem scanning was about 40 min. This study is the first to report antemortem MR images in horses. we first performed postmortem MRI imaging of the equine superficial digital flexor tendon (SDFT), deep digital flexor tendon (DDFT), and ligaments on removed limbs, in order to determine the imaging conditions, including the imaging slice position, body position and coil settings. Then, using these conditions, we attempted to take MR images of flexor tendons on horses under anesthesia. To the authors' knowledge, antemortem MRI of equine limbs has not yet been reported, and this is the first report of MR images of antemortem equine limbs. MATERIALS AND METHODSPostmortem specimens: The forelimbs were removed from a number of horses that had been slaughtered for reasons unrelated to the condition of their musculoskeletal systems. A total of 12 limbs, 4 right forelimbs and 4 left forelimbs from Thoroughbreds, and 2 right forelimbs and 2 left forelimbs from Percherons were examined. Radiographs of the carpal joints, metacarpophalangeal joints and metacarpal bones were normal. The limbs were frozen, then thawed 12 hr before imaging. The shoes were removed. A 0.2 tesla MRI system (MRP-20 Hitachi Medical Co., Japan; 38 × 100 × 133 cm bore size) with a permanent magnet was used for the study. A knee-quadrature coil (QD coil) with a diameter of 15 cm and a length of 18 cm was used. MR images were made in the transverse and sagittal planes; the transverse slice thickness was made in 10 mm, and the sagittal slice thickness was done in 5 mm sections. Spin-echo sequences were used and T1 weighted images (pulse-repetition-time (TR)/echo-delay-time (TE)=500/25 ms) and T2 weighted images (TR/TE=2000/ 110 ms) were obtained. In the postmortem specimens 30 slices were taken in the transverse plane and 5 slices in the sagittal plane. The time required to complete the MR imaging examination was about 60 min.Antemortem specimens: The antemortem specimens were 3 horses kept at the Veterinary Hospital of Yamaguchi Flexor tendinitis -especially superficial digital flexor tendinitis and deep digital flexor tendinitis -is a serious problem for racehorses. Inflammation of a tendon can be acute or chronic, with varying degrees of fibril disruption [3,11,13,14,19,20]. Methods of diagnosing flexor tendinitis include ultrasonography, scintigraphy, magnetic resonance imaging (MRI) and thermography. Diagnostic ultrasonography is widely used for flexor tendinitis and for visualizing injuries to the tendinous and ligamentous structures of the distal equine limb [6]. I...
