Now we needed volunteers to test the
system and establish imaging
parameters…
The First “Volunteer”
The First “Volunteer”
Normal Thoracolumbar Spine
The First Clinical Patient
7-year-old MC Weimaraner
 One year long history of bilateral hind
limb weakness that had progressively
worsened
 Recent onset seizures
 Plan: MRI brain
+/- MRI lumbar spine

The First Clinical Patient

Neurologists
eagerly awaiting
results of the first
scan
The First Clinical Patient
Intracranial contrast-enhancing mass
Presumptive diagnosis: Cystic meningioma
Other Patients
1-year-old M Mastiff
 Wobbly in hind limbs since birth,
progressive
 Hind limb paresis except when on
prednisone
 Plan: MRI thoracolumbar spine

T2
FLAIR
Diagnosis: Arachnoid cyst T 12/13
Good recovery after surgery
More Neurology Patients
7-year old Shi Tsu with neck pain
Diagnosis: Intervertebral disc
extrusion C3/4; Incidental finding
of a brain cyst (“quadrigeminal
cistern cyst”)
Good recovery after surgery
The First Orthopedic Patient
Partial rupture of the cranial cruciate ligament, degenerative
joint disease, subchondral sclerosis and cyst
The First Oncology Patient
9-year old American Bulldog; Known MCT on back
MRI performed to evaluate margins
Additional smaller mass found unexpectedly
Arguably the cutest patient…
Approximately 4 month old Black Bear
(8 lb)
 Brought in from Appalachian Bear
Center
 Blindness, running in circles
 Plan: MRI brain

Diagnosis: Congenital dilation
of lateral ventricles
(Hydrocephalus)
More Exotics – From Large…
2-year old F Tiger
Ataxia
Normal brain MRI
More Exotics – … to small
Rabbit, few months old
1 month history of seizures
Normal limited brain MRI
Initial Large Animal Experience
4 month old Potbellied Pig
 Fever (105°F) and rear leg weakness
 Plan: MRI lumbar spine

Imaging Diagnosis: Diffusely contrast enhancing
areas in epaxial muscles
-> Muscle biopsy: Myofiber necrosis and
degeneration with secondary inflammation and
regeneration
Ddx: nutritional (white muscle disease), toxic,
neurogenic, infectious or ischemic
STAY TUNED!
