Diagnostic Imaging
• X-rays
– Planes of Views
– Positioning
– Projection
– Procedures
X-ray Planes of View
• Coronal/Frontal Plane (Ventral; Dorsal)
– Vertically divides body into
• Front and back; anterior/ventral; posterior/dorsal
• Sagittal Plane
– Vertically divides body into right and left halves
– Midsagittal – midline; two equal halves
• Transverse (Horizontal/Axial)
– Horizontally divides body into
• Superior/inferior OR cranial/caudal
Positioning & Projection
• Positioning is based on the part of the
body that is closest to x-ray film
• Projection is the path that the beams take
through the body
• PA = Posteroanterior projection
• AP = Anteroposterior
• Lat = Lateral or side view
• LPO = Left posterior oblique
MS X-ray Procedures
• Arthrography
– X-ray of joint after contrast material injection
• Computed axial tomography (CT/CAT)
– X-rays of “slices” of body
– Processed to make 3-D images
• Fluoroscopy
– Continuous x-ray beam creates “movie”
– Used for invasive procedures/operations
– Adjustments
• Magnetic Resonance Imaging (MRI)
– Noninvasive, 2-D, spinal cord, etc.
Bone Scans

procedure
Fractures
– Uses tracers (radionuclides).
Arthritis
– Tracers emit a type of
Paget disease of bone
radiation called gamma waves
Bone tumors
• Two Parts
– Injection
Infection of joints,
– Scan
replacements, or bone
• # of phases may be ordered
(osteomyelitis)
• SPECT sometimes ordered
Fibrous dysplasia
– Single Photon Emission
Avascular necrosis or
Computerized Tomography
impaired bone blood supply
– Visualizes anatomy AND
Unexplained bone pain
function
Metastatic ca from lung,
breast, prostate, etc.
Densitometry
• Dual energy X-ray absorptiometry (DXA, DEXA)
• Bone density test
– Special X-rays to measure # of grams of calcium and
other bone minerals in a segment of bone
– Usually done on bones most likely to break because
of osteoporosis
• Lumbar vertebrae (central)
• Neck of femur
• Wrist and forearm
• Heel, finger (peripheral) (screening)
DEXA
• Results
– T-score = bone density compared to expected in
healthy young adult of same sex.
• Number of units — standard deviations (SD) —
that bone density is above or below the standard
• Above -1 = Normal
• Between -1 and -2.5 = Osteopenia
• Below 2.5 = Osteoporosis
– Z-score = number of SDs above or below what's
normally expected for someone of similar
• Age, sex, weight, and ethnic or racial origin
Interpreting T-scores and Z-scores

• Procedure
– Local anesthetic
– Positioned to open spaces between vertebrae
– Contrast is administered
– Fluoroscope (combines an x-ray with TV) takes images
• Mostly replaced by MRI -safer, simpler, more detailed
• Myelography w/ CT
– When more detail of spinal canal & bone needed
– If MRI not available/isn’t safe (person w/ heart pacemaker)
Arthrocentesis

– Removing bony growth and related soft tissue
– Often done in combination w/other procedures
– Silver
• Modified McBride bunionectomy
– Removal of bunion, rebalancing of the big toe joint by
releasing the tight tendons on the lateral side
– Tightening the joint capsule on the medial side
– Sometimes removing one of the sesamoid bones
Bunion Osteotomy
• Many types
• More severe the bunion, more proximal
the osteotomy on the metatarsal bone
– Distal = less of an angle of divergence
– Proximal = more of an angle
Bunion Osteotomy
• Keller procedure
– Combined soft tissue release
– Removal of the medial eminence with
– Resection of the proximal end of proximal phalanx
• Akin procedure - hallux valgus interphalangeus
– Deformity is located at the interphalangeal joint

phalanx
– Medial eminence of the metatarsal head is resected
– Medial capsular reefing is done
– Usually performed w/ Silver or McBride procedure
Bunion Osteotomy
• First metatarsal head osteotomy
– Most commonly performed bunionectomy
– Depends on perceived etiology of the condition and amount
of correction required
• Chevron (Austin) osteotomy
– Younger patient, no joint arthrosis, mild/moderate deformity
• involves a "V" shaped osteotomy of the distal metatarsal
• allows the first metatarsal head to be shifted laterally
– Proximal metatarsal osteotomy for hallux valgus is indicated
for patients with moderate to severe deformities
– May be combined w/ Silver or McBride
Bunion Osteotomy
• Mitchell bunionectomy
– Moderate to severe deformities of the
intermetatarsal angle and hallux valgus
– Metatarsal osteotomy that displaces
metatarsal head laterally
– More proximal than the Chevron osteotomy,
can correct more severe deformities than
Chevron
• Myerson/Ludloff
Bunion Lapidus procedure

• Dx = Patients with arthritis of the big toe joint
associated with a bunion deformity
– Fusion of the joint or by
– Removing a portion of the joint (arthroplasty)
• Excision arthroplasty
– One or both articular ends of the bones are excised
– Gap is created between them
– Gap fills with fibrous tissue, or a pad of muscle or other
soft tissue may be sewn in between the bones
– Interposed tissue allows ROM, but joint often lacks
stability.

– Tumor size and #
– # = size/extent of tumor
and spread (after each
– Lymph node involvement
letter)
– Cell type and tumor grade
• Osteosarcoma (rare)
– Metastasis
– Enneking staging system
(3 stages)
• Grade, size, spread
• I to III (A or B)
– AJCC system (4 stages)
• I to IV

TX can’t evaluate
T0 No evidence
Tis Carcinoma in situ
T1, T2, T3, T4 Size and/or extent of tumor
• Regional Lymph Nodes (N)
– NX can’t evaluate
– N0 No regional lymph node involvement
– N1, N2, N3 Involvement of regional lymph nodes
• Distant Metastasis (M)
– MX can’t evaluate

TNM Ca Staging
Stage
Stage 0
Stages I – III
Stage IV
Definition
Carcinoma in situ (early cancer that
is present only in the layer of cells in
which it began)
Higher numbers indicate more
extensive disease
Cancer has spread to another organ
Different combinations of TNM levels =
different stages for different CAs
