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
Neurologists eagerly awaiting results of the first scan
The First Clinical Patient
Intracranial contrast-enhancing massPresumptive diagnosis: Cystic meningioma
The First Clinical Patient
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

Diagnosis: Arachnoid cyst T 12/13Good recovery after surgery
7-year old Shi Tsu with neck painDiagnosis: Intervertebral disc extrusion C3/4; Incidental finding of a brain cyst (“quadrigeminal cistern cyst”)Good recovery after surgery
More Neurology Patients
The First Orthopedic Patient
Partial rupture of the cranial cruciate ligament, degenerative joint disease, subchondral sclerosis and cyst

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 regenerationDdx: nutritional (white muscle disease), toxic, neurogenic, infectious or ischemic
