Bone mineral density (BMD) is one of the indications of the strength and health. BMD measured by quantitative computed tomography (QCT) was compared with that measured by dual energy X-ray absorptiometry (DXA) and radiographic bone aluminum equivalence (RBAE). Limbs were removed from horses that had been euthanized for reasons not associated with this study. Sixteen limbs (left and right metacarpals and metatarsals) from 4 horses were used to compare BMD as measured by QCT with those measured by DXA and RBAE. There was a strong correlation between BMD values measured by QCT and those measured by DXA (R2=0.85); correlation was also observed between values obtained by QCT and those obtained by RBAE (R2=0.61). To investigate changes in BMD with age, 37 right...

Techniques for measuring hydrogen (H2) and methane (CH4) levels in breaths were assessed in horses with gastrointestinal (GI) diseases. A total of 31 horses were studied: 11 healthy horses (Group A), 10 horses with GI diseases (Group B), and 10 horses with diseases without GI involvement (Group C). Expired gases were measured using gas chromatography. CH4 levels in Group A were significantly lower than those in Group B. In Group B, CH4 levels were significantly higher after treatment. Fluctuations in H2 and CH4 levels in breath were associated with changes in GI function.

Basic Assessment of Diagnosis by MDCT in Horses
Provedor de dados: 19

In this equine study, we used an MDCT unit and a trestle for large animals to assess the utility of MDCT in the diagnosis locomotor system disorders and problems in the head and spine. We used a mature thoroughbred horse under general anesthesia and 5 specimens. For specimens, MDCT images were compared with other images taken by a computed radiography X-ray unit. In the live horse, use of the trestle for large animals enabled scanning under general anesthesia. In specimens, MDCT created 3D images of the fractured lesions and evaluation of multiple cross-sectional and sagittal images was possible. Further, multiple sagittal images and virtual endoscopic images revealed details of a spinal canal stenosis in the swayback case. These results indicate that MDCT...
