“…Another benefit of ultrasound, while not utilized in this study, is that ultrasound allows the use of Doppler interrogation to help assess the vascularity of tendon lesions. The exact significance of increased Doppler signal still requires additional research, but it can be useful to help identify or confirm lesions and assess for active increased vascularity [32].…”

Damage to the soft tissue structures of the digit is a common source of equine lameness. While magnetic resonance imaging (MRI) allows for the most complete diagnostic imaging of the equine digit, ultrasound is more readily available and less expensive. This prospective diagnostic accuracy study compares ultrasound to MRI for the diagnosis of injuries visible with ultrasound within the digit, including the deep digital flexor tendon (DDFT), collateral sesamoidean ligament (CSL), and navicular bursa. Clinical patients underwent an MRI of the digit and a blinded ultrasound of the digit between the heel bulbs, and results of the two modalities were compared. A total of 70 ultrasound and MRI exams of 45 horses were included. Ultrasound had good sensitivity (85%), moderate specificity (60%), and accuracy of 70% for evaluating the dorsal tearing of the DDFT. Accuracy was lower for navicular bursa effusion (67%), navicular bursa proliferation (61%), and CSL enlargement (61%). Tearing of the DDFT distal to the navicular bone was identified with MRI in 27 limbs, 20 of which also had dorsal damage proximal to the navicular bone identified with ultrasound. Ultrasound evaluation remains a useful screening tool, particularly for the assessment of DDFT tearing proximal to the navicular bone but risks under-diagnosing pathology to the navicular bursa and CSL. Clinically significant concurrent damage to the distal DDFT and other osseous and soft tissues in the hoof capsule is unlikely to be identified without MRI.

“…A limitation of the study was the use of grayscale B-mode ultrasonography only, as this modality is less sensitive than color doppler or power doppler techniques in detecting blood vessels. However, previous studies have reported that power Doppler signals indicating neovascularization are not detected in structures such as suspensory ligament branches and the superficial digital flexor tendon when there are no abnormal findings detected by B-mode ultrasonography [ 10 , 26 ]. The fact that power Doppler signals were also seen in suspensory ligament branches of sound limbs albeit with abnormal B-mode ultrasonographical findings [ 26 ], complicates the interpretation of the clinical relevance of such findings and highlights the need for histopathological confirmation of disease.…”

“…However, neovascularization of the patellar tendon identified by power doppler ultrasonography has been identified as a more specific diagnostic indicator of clinical patellar tendinopathy [ 7 ], most likely as nociceptive nerve fibers accompany the blood vessel ingrowth [ 9 ]. Power doppler ultrasonography has also been used for detecting neovascularization in superficial digital flexor tendinopathy in horses [ 10 ] and could potentially be useful for diagnosing PL lesions. However, whereas the normal vascular architecture of the equine superficial digital flexor tendon has been described [ 11 ], such information is lacking for the equine PLs.…”

Background Interpretation of patellar ligament (PL) ultrasonography may be difficult, as hypoechoic or heterogenous echogenicity are common findings. Verifying suspected disease of equine PLs by histopathology is also problematic as descriptions of normal PL vascularity and histology are scarce. The current study describes the PL and infrapatellar fat pad (IFP) vascular pattern from computed tomography scans of barium perfused normal equine specimens (n = 8; age 10 days to 18 years), as well as routine histology to serve as a reference for future investigations into PL pathology and IFP disease. Results The PLs received a bipolar blood supply. Vascular architecture consisted of numerous distinct longitudinal vessels with several horizontal connections, which branched into extensive latticeworks of smaller vessels throughout the ligaments. Several vascular connections between the PLs and the IFP were identified. One distinct longitudinal vessel was seen entering each of the IFP lobes at the distocranial aspect, branching extensively into lobar vascular networks which anastomosed by several horizontal branches at the mid portion of the IFP where the two lobes merge. Histologically, there were large variations in PL interfascicular endotenon thickness, vascularity and fatty infiltration; these parameters increased with age for the intermediate and medial PL. Areas of metaplastic tenocytes / chondroid metaplasia were identified in all investigated adult medial PLs; in 2/7 in the intermediate PL and in 4/7 in the lateral PL. The adult IFP consisted of white unilocular adipose tissue, organized in lobules separated by thin connective tissue septa increasing in thickness towards the periphery and the distocentral aspect. Conclusions The equine PLs and IFP are highly vascularized structures with ample vascular connections suggestive of crosstalk. This, together with the large variation in PL endotenon thickness, vascularity and fatty infiltration, should be taken into consideration when assessing potential PL histopathology as these changes increase with age and are found in horses without clinical signs of stifle disease. Metaplastic tenocytes / chondroid metaplasia should be considered a normal finding throughout the medial PL and is not age dependent. The role of the equine IFP in stifle disease has yet to be elucidated.

La ultrasonografía, en medicina equina, es una técnica fundamental para el diagnóstico de las claudicaciones y en la evaluación de la disminución del rendimiento deportivo. A pesar del gran desarrollo del Modo B es escasa la utilización del Doppler Color y específicamente del Doppler de Poder o power angio en la evaluación de las afecciones músculo-esqueléticas en el equino. El objetivo de este trabajo fue analizar los alcances, ventajas y limitaciones del estudio ultrasonográfico con Doppler de Poder asociado al Modo B en la evaluación de 122 afecciones músculo-esqueléticas en equinos deportivos, de entre 2 y 15 años, de ambos sexos y distintas razas Se utilizó un ecógrafo portátil Sonoscape E2 con sonda lineal de 7-11 Mhz y convexa de 2,5-5 Mhz. De la totalidad de las lesiones músculo-esqueléticas evaluadas (n:122) se observó presencia de señal con el Doppler de Poder en 46/122 siendo la más observada la de grado I (29/46), seguida del grado II (13/46) y por último de grado III (4/46). Si bien este es un estudio preliminar y faltan más resultados para poder aplicar análisis estadísticos, según la experiencia de los autores, el Doppler de Poder complementando los estudios ultra-sonográficos en Modo B, ha demostrado ser una herramienta de gran utilidad para el diagnóstico, seguimiento de la evolución de las lesiones, evaluación de la respuesta terapéutica y con valor predictivo de posibles lesiones futuras.
