The impact of different acquisition times (AqT) and technetium-99 m-labeled (^99mTc) diphosphonates on the image quality of bone scintigraphy is poorly documented in horses. The aim of this prospective experimental study was to evaluate the impact of varying ^99mTc-disphosphonates and AqT on...

This prospective, cross-sectional, pilot study aimed to investigate the effects of furosemide as a diuretic on the image quality of bone scintigraphy performed using ^99mTc-HDP and to investigate the impact of furosemide on the radiation dose rate. Thirty-one horses undergoing bone scintigraphy were ...

Background: In equine skeletal scintigraphy, there is no information about the possible influence of different phosphonate compounds on image quality. Methods: This prospective randomised study determined bone uptake changes and image quality for hydroxymethylene diphosphonate (HDP) and methylene...

Lameness originating from the proximal metacarpal region is known as one of the most common causes of lameness in horses. Differential diagnosis is based on the exclusion of other possible causes. Diagnostic imaging modalities, such as radiography, ultrasonography and scintigraphy, are often used...

Bone scintigraphy is the only imaging technique able to demonstrate organ function rather than anatomical details. It involves intravenous injection of a radiopharmaceutical that binds to the bone structures and display alteration in osteoblastic activity. It is commonly used in horses presented...

The caudal cervical spine is causally involved in diseases more often than the cranial parts. However, these sections are more difficult to access for computed tomographic examinations on the standing horse. The first results of the use of cone beam-computed tomography (CBCT) in the area of the...

This study was performed to evaluate the systemic short-term effects of tiludronate intravenous infusion on serum biochemical variables when administered as one single-dose in horses that undergo bone scintigraphy within 24 to 36 hours prior to treatment. Thirty-eight horses were enrolled in the...

Background: Positron emission tomography (PET) is a cross-sectional, functional imaging modality that has recently become available to the horse. The use of ¹⁸F-sodium fluoride (¹⁸F-NaF), a PET bone tracer, has not previously been reported in this species. Objectives: To assess the feasibility of ...

Positron emission tomography (PET) imaging had a higher interobserver agreement than scintigraphy for assessment of the racehorse fetlock and detected additional abnormalities, in particular in the proximal sesamoid bones.

A 5-year-old Hanoverian gelding with acute moderate right forelimb lameness underwent nuclear scintigraphy, which identified marked increase in radiopharmaceutical uptake of the proximomedial aspect of the right metacarpus. Ultrasonography and radiography identified sclerosis and exostosis of the...
