The canine common calcanean tendon can be repaired successfully using a modified Kessler knotless barbed technique. A long‐term ultrasound follow‐up showed improved and increased normal tendon fibrillar echotexture and homogeneity.
Susceptibility artifacts caused by ferromagnetic implants compromise magnetic resonance imaging (MRI) of the canine stifle after tibial plateau leveling osteotomy (TPLO) procedures. The WARP-turbo spin echo sequence is being developed to mitigate artifacts and utilizes slice encoding for metal artifact reduction. The aim of the current study was to evaluate the WARP-turbo spin echo sequence for imaging post TPLO canine stifle joints. Proton density weighted images of 19 canine cadaver limbs were made post TPLO using a 3 Tesla MRI scanner. Susceptibility artifact sizes were recorded and compared for WARP vs. conventional turbo spin echo sequences. Three evaluators graded depiction quality for the tibial tuberosity, medial and lateral menisci, tibial osteotomy, and caudal cruciate ligament as sufficient or insufficient to make a diagnosis. Artifacts were subjectively smaller and local structures were better depicted in WARP-turbo spin echo images. Signal void area was also reduced by 75% (sagittal) and 49% (dorsal) in WARP vs. conventional turbo spin echo images. Evaluators were significantly more likely to grade local anatomy depiction as adequate for making a diagnosis in WARP-turbo spin echo images in the sagittal but not dorsal plane. The proportion of image sets with anatomic structure depiction graded adequate to make a diagnosis ranged from 28 to 68% in sagittal WARP-turbo spin echo images compared to 0-19% in turbo spin echo images. Findings indicated that the WARP-turbo spin echo sequence reduces the severity of susceptibility artifacts in canine stifle joints post TPLO. However, variable depiction of local anatomy warrants further refinement of the technique.
A 13-year-old female spayed Domestic Shorthair cat was presented to Texas A&M University Veterinary Medical Teaching Hospital (VMTH) for a chronic nail bed infection. The owner noticed the cat favoring and holding up the left front paw about 4-6 weeks prior; no bleeding or abnormal discharge was noted. The cat was initially evaluated by the primary care veterinarian for limping, where it was noted that the nails had grown into the footpads on the 2nd and 3rd digits. The paw was also swollen and painful. The nails were trimmed and the cat was administered antibiotic and antiinflammatory injections. The cat returned to the primary care veterinarian 2 weeks later for re-evaluation, but showed no improvement. Oral antibiotics were initiated prior to referral.At presentation to the VMTH, digits 2 and 3 of the left front paw were swollen, fairly firm, and painful. Mild exudate was present along the ventral margin of the claw fold. Cytologic evaluation of the exudate surrounding the second digit on the left forelimb revealed moderate numbers of neutrophils with rare bacterial cocci. An aspirate of a lesion on the third digit of the left forelimb was obtained (Figure 1). Figure 1. Aspirate of a lesion on the third digit on the left forelimb in a cat, Diff-Quik, 9 60 objective.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
