Πολύ ενδιαφέρον post από την Equipixel σχετικά με την αξία της επαναληπτικής μαγνητικής σε άλογα με proximal suspensory disease. 👏
Η υποχώρηση του οστικού οιδήματος στο McIII (τρίτο μετακάρπιο) συσχετίζεται με επιστροφή στην άσκηση , ενώ η πλήρης “ομαλοποίηση” της εικόνας του συνδέσμου δεν ήταν απαραίτητη.
Ένα πολύ καλό παράδειγμα του πώς το standing MRI μπορεί να βοηθήσει όχι μόνο στη διάγνωση αλλά και στην παρακολούθηση της επούλωσης και στον σχεδιασμό της επιστροφής στην άσκηση.
Very interesting post from Equipixel highlighting the value of repeat MRI in horses with proximal suspensory disease. 👏
The study showed that resolution of bone oedema within the McIII was associated with return to work, while complete normalisation of the suspensory ligament itself was not required.
Another great example of how standing MRI can help not only with diagnosis, but also with monitoring healing and helping guide return-to-exercise decisions.

Do You Know? · Episode 16
We routinely use MRI to diagnose proximal metacarpal pain when radiography and ultrasound fall short. But once the horse is in rehab, what do we actually look for on the rescan to decide if they are ready to return to work?
A new retrospective MRI follow-up series of 17 sport horses finally gives us some answers, and the findings are clinically important. The McIII STIR hyperintense signal resolved in every single horse that successfully returned to soundness. In 75% of horses that did not return to work, it did not resolve. This is your imaging benchmark. Mean resolution time was 94 days, with a range of 47 to 202 days, which translates to a suggested primary rescan window of 120 days, covering 87% of the study population. If the signal is still present at 6 months without improvement, the prognosis warrants careful reassessment.
Equally important is what you do not need: complete normalisation of the proximal suspensory ligament on T1W or T2*W GRE sequences was not observed in any horse, yet all returned to full work. Residual PSL signal is not a barrier to soundness. PSL cross-sectional area also remained stable throughout, confirming it is not a reliable dynamic marker of recovery.
This study also introduces a practical structured rescan framework: 120 days primary, then additional 60-day intervals if STIR signal is reducing but not yet resolved.
The message is clear: watch the bone, not just the ligament.
