Quiz 2 Flashcards
Self Limiting Disease of Large Breed Dogs with Shifting Leg Lameness characterized by:
Increased Medullary Opacity
Lesion often Begins at the Nutrient Foramen

Panosteitis


Yes
*Cortex Destruction and Indistinct Transition Zone
What Joint Condition is Detected in this Radiograph

Joint Effusion

What Bone Condition can be Detected in these Radiographs

Aseptic Necrosis of Femoral Head (Legg-Calve-Perthes)

Once the Radiographs are made using PenHIP Screening, they are submitted and a Distriction Index is Calculated. What equation is used to Calculate the Distraction Index
D = Distance Center Moves Laterally
R = Radius Of Femoral Head
*Ex. A Distraction Index of 0.75 is Very Big- A Lot of Laxity

Infection of the Disk that Results in Destruction of the Endplates
Discospondylitis
*Need Two Radiographic Views on these Dogs- Lateral and Dorsoventral or Ventrodorsal
CHRONIC Disk Disease where the Annulus/Nucleus Protrudes into the vertebral canal with Spinal Cord compression that typically occurs in Large Breed Dogs
Hansen Type II

What Spine Condition is Detected in this Radiograph?

Herniated Disc within the Vertebral Canal
*Are these Herniated Disks the Cause of the Dogs Problem?- Can’t tell, these could be Chronic Type II Disks and Clinically Insignificant
When Performing a Spinal MRI, if we Perfom a _____ Image we will Only see the Fluid within the Subarachnoid Space
STIR
*STIR- Gets rid of the Signal from Fat

Must be distinguished from an Underexposed Radiograph
On Radiograph you see a Bulge between 1:00-2:00. What does the Bulge Represent?

Main Pulmonary Artery
*Enlargment of Main Pulmonary Artery- Common in Heartworm
What Bone Condition is Detected in these Radiographs

Osteochondrosis

Bone Condition that can Mimic Primary Bone Tumor, but is Often:
Polyostotic (More than One Bone)

Fungal Osteomyelitis
*Are you in an Endemic Region? California and Arizona- Coccidiodomycosis. Ohio River Valley Area- Blastomycosis

Typical Extradural Appreance of a ____

Type II Disc Herniation


Low
*Salter Harris Type I Fracture
Radiographs show Hip Dysplasia under ______ Classification

OFA
*Problems with OFA- Not evaluating Joint Laxity and is Extremely Subjective
_____ Ventricular Hypertrophy is More Common and Characterized by:
Increased Sternal Contact
Elevation of Apex from Sternum
Backward “D” Appearance

Right
*Causes of Right Ventricular Hypertrophy- Pulmonic Stenosis, Heartworm
*Backward “D” Appearance

Heart Condition seen in this Radiograph

Left Atrial Dilation
*Left Atrial Dilation- Best Seen in Lateral View

Know this Chart

*Lysis or Sclerosis is not a Factor of Bone Aggressiveness- The Opacity of the Lesion doesn’t tell us whether a Lesion is aggressive or Not

What Joint Condition is Detected in this Radiograph?

Hip Osteoarthritis
*Osteophytes are detected

Physeal Fracture Classification System where the Chance of a Secondary growth anomaly is much Higher as the Ranking Increases

Salter Harris
*Growth Plate Fracture Classification- Applies Only to Skeletally Immature Patients
*Chance of Secondary Growth Anomaly is much Higher with Type V than with Any other Type. Hardly ever get a Secondary Growth Anomaly with a Salter Harris Type I Fracture
*Salter Harris V- Compression Injury of the Growth Plate. Cannot Diagnose Radiographically

The Earliest Radiographic sign of Canine Hip Dysplasia
Joint Laxity
What can be seen in this Radiograph of Bone

Metatarsal Sequestrum
*Periosteum is Damaged, which can lead to Sequestration because of the Disruption of the Blood Supply- The piece of Bone dies off (Necrosis)

Lumbosacral (L7-S1) Spinal Cord Abnormality with these Clinical Signs:
Lumbosacral Pain
Reduced Tail Wagging- Caudal Nerve
Weakness/Lameness in One or Both Hind Limbs- Sciatic Nerve
Severe Compression of Nerve Roots
Fecal and Urinary Incontinence- Pudendal Nerve
Cauda Equina Syndrome
*Large Dog Problem
