“…The cartilage and synovial fluid revealed moderate signal intensities and appeared grey. A similar pattern of MRI signal intensities was reported in MR imaged equine (Dyson & Murray, ; Smith et al, ), bovine (Raji et al, ) and camel cadaveric feet (Hagag et al, ). On the other hand, in T2‐W images the adipose tissue, fatty marrow and trabecular bones revealed a decrease in their signal intensities and exhibited a greyish‐white colouration, whilst the cartilage and synovial fluid appeared with much enhanced signal intensities compared to those in T1‐W images and appeared white.…”

“…Thanks to the availability of cost‐effective low‐field MRI facilities, several descriptive studies of foot MRI anatomy were reported during the past two decades in several species including the canine (Ober & Freeman, ), equine (Kleiter et al, ; Smith, Dyson, & Murray, ), bovine (Raji, Sardari, & Mirmahmoob, ) and camel (Hagag et al, ). However, those entailed the buffalo foot is still lacking.…”

Buffaloes represent a major source of milk production, especially in developing countries including Egypt. The buffalo foot is frequently involved in a large proportion of lameness cases. The relatively small size and complexity of its structures often render the radiographic evaluation of the foot challenging. Magnetic resonance imaging (MRI) is a noninvasive imaging technique that is regarded as both safe and accurate for assessment of the foot disorders in both man and animals. The purpose of the current investigation was to describe the MRI anatomy of buffalo foot using cadaveric hind feet. The feet were subjected to consecutive MRI scanning using a 0.3 Tesla scanner. Both T1-weighted (T1-W) and T2-weighted (T2-W) spin-echo pulse sequences were applied in dorsal, sagittal and transverse planes. The heterogeneity of signal intensities noted amongst foot components allowed for clear differentiation of bones, tendons, ligaments, adipose tissue and synovial fluid. The T1-W images provided an excellent overview of the foot. They were valuable for visualizing the bones and the alignment of tendons and ligaments. The T2-W images were particularly useful for the evaluation of synovial structures such as tendon sheaths and joint cavities. A communication between the two plantar sacs of the metatarsophalangeal (fetlock) joints was evident in T2-W images. MRI findings were further confirmed using relevant gross anatomical sections. The present study establishes a detailed MRI anatomic reference of buffalo foot that could help veterinary researchers, clinicians and surgeons for increasing the accuracy of interpretation of foot MRI scans of both healthy and diseased animals.

“…These findings were in line with those of Kraft and Gavin () in equine, Hagag and Tawfiek () in bovine and Ibrahim et al (, ) in camel. In addition to that, these advantages of CT and MRI providing excellent views of the cross‐sectional imaging aid in diagnosis of the musculoskeletal disorders (Raji, Sardari, & Mohammadi, , ). CT images provide excellent visualization of the bony structures and can differentiate osseous changes before they are clinically or radiographically apparent (Young, Samii, Mattoon, Weibrode, & Bertone, ), and also can be used for assessment of soft tissue structures (Awaad, Abdel Maksoud, & Fathy, ; Seddek, Abedellaah, & Awaad, ).…”

“…However, Abdellatif et al () in the same animal reported that the hoof capsule and its corium are best evaluated on sagittal and transverse MR images where the hoof was depicted with low signal intensity and cannot be observed on black background, while the corium visualized with intermediate signal intensity. On contrary, the hoof corium of bovine appears black on MRI (Raji et al, ). This variable pattern of tissue intensity on both CT and MRI might be due to either technical factors; different acquisition settings, variable magnetic field of MRI and apparatus used or species‐specific anatomic features.…”

“…However, the need for general anaesthesia and high costs limited using these techniques in veterinary clinics (Arencibia et al, ). Meanwhile, low cost‐effective MRI and CT facilities motivated several studies on different animal species; canine (Gielen, Rycke, Bree, & Simoens, ; Ober & freeman, ; Ricciardi & Lenoci, ), equine (Hevesi et al, ; Sampson & Tucker, ; Sherlock, Mair, Ireland, & Blunden, ), camel (El‐Nahas et al, ; Alsafy, El‐Gendy, & Kamal et al, ; Ibrahim, Adam, & Tawfiek, , ) and bovine (Abdellatif, Hamed, El‐Shafaey, & Eldoumani, ; Raji, Sardari, & Mohammadi, , ). However, limited studies are attended for pastern and coffin joints in buffalo.…”

The purpose of this study was to describe normal magnetic resonance imaging and computed tomographic anatomy of pastern and coffin joints in Egyptian buffalo using cadaveric distal limbs. This study was achieved using twelve fresh cadaveric distal limbs from adult healthy buffaloes of both sexes. These cadaveric limbs were scanned using a 1 Tesla MRI scanner and CT scanner, injected with red latex, frozen at −20°C for 1 week, and then sectioned into sagittal, dorsal and transverse slices. The obtained MR and CT images were selected to be matched with their corresponding anatomical cross‐sections for identification and evaluation of the clinically correlated anatomical structures of the pastern and coffin joints. The difference in signal intensities on CT and MRI scans amongst the tissues allowed clear differentiation of major bone and soft tissue structures of the pastern and coffin joints. CT provided a high spatial resolution of bone and soft tissue structures, however, MRI allowed a better and higher resolution and definition between soft tissues. The current study provided a normal CT and MRI anatomic reference which could help veterinary clinicians for interpretation and diagnosis of the clinically affected pastern and coffin joints in buffalo.
