Flashcards in Radiology of the Lower Limb Deck (27):
1

frog-leg lateral

good for displaying femoral head in acetabulum

2

what can frog-leg lateral help diagnose?

FAIS
femoroacetabular impingement syndrome

3

groin-lateral view

used for visualizing the anterior and posterior head of femur and for analyzing angle between shaft and neck/head of femur

4

if angle increases

will medially rotated look
"toed in" - pigeon toed

5

if angle decreases

duck walk

laterally rotated look

6

CT with contrast through upper thigh

gluteus maximus in a different plane
so it looks different

7

MRI T1 weighted image

from the bottom

8

what converges to pes aneserinus?

sartorious, gracilis, semitendinosus

9

medial knee plain film?

can see intercondylar notch of femur

10

fabella

sesamoid bones within the lateral head of gastrocnemius

11

sunrise view

plain film

allows you to view the patellofemoral joint space

should be equal on medial and lateral surfaces

can indicate patellafemoral syndrome

12

coronal MRI of knee

can view cruciate ligaments and meniscus

also, can view posterior meniscofemoral ligament

13

bow ties

looking at the articular cartilage of knee

can see different representations of cartilage at different levels of view

14

sagittal MRI of knee

can see anterior and posterior cruciate ligaments

15

salter harris classification of femoral epiphyseal fractures

I. through epiphysis
-non union or non growth
II. through epiphysis and metaphysis
-differential bone growth
III. vertical through two condyles and epiphysis
-splits knee joints NO GOOD
IV. vertical through two condyles and metaphysis
-splits knee joints NO GOOD
V. compression of eiphysis

16

good on medial plain film of knee

adductor tubercle

17

axial MRI

anterior tibial arteries - anterior to interosseous membrane
posterior tibial and fibular vessels - posterior to interossesus membrane and tibialis posterior

18

lateral oblique ankle plain film

can see articulation of the mortise/tenon relationship

19

what shows age?

look for epiphysis in bone

20

medial ankle plain film

see the overlap of the malleoli

can see density of bones

assess transverse tarsal joint***

21

sagittal MRI of ankle

interosseous ligament - cuboid slice

22

dorsal view of foot plain view

can see the joints of foot

23

lateral oblique plain film of foot

affords assessment of 5th metatarsal

24

medial view of foot plain film

assessment of lateral, medial longitudinal and transverse arches

25

plain film with contrast

can see vasculature

26

lateral AP plain film with contrast in leg

can see the deep plantar artery

also, gives you depth for the vasculature

27

lytic lesion

from renal metastasis

caudmanns triangle
-elevation of periosteum due to swelling and cancer formation
