Bone Imaging - Basics and Non-Fx
Bone Dz – Question well answered
On plain radiographs the (cortex/medullary cavity) produces a smooth white shell of varying
thickness and appears as a dense white band along the outer margins of the bone and
completely surrounds the bone - correct answer ✔✔cortex
On plain radiographs the (cortex/medullary cavity) appears as a core of less dense, grayish
material inside the cortical shell - correct answer ✔✔medullary cavity
T/F: The term orthogonal refers to the fact that almost all radiographic evaluation of a bone
begins with 2 views exposed at 45 degrees of each other - correct answer ✔✔false (should be
90 degrees aka right angles of each other)
T/F: Plain films can view entire circumference of tubular bone but they are just not good for
evaluating soft tissue injuries - correct answer ✔✔false (they CANNOT view the entire
circumference of tubular bone and they're NOT good for soft tissue injuries)
T/F: CT and MRI are able to visualize entire circumference and internal matrix of bone - correct
answer ✔✔true
(CT/MRI) is excellent for evaluating components of the medullary canal and non-osseous
musculoskeletal structures thus it is used to categorize marrow disorders - correct answer
✔✔MRI
Which of the following best describes reversal of normal conversion of marrow cells?
A) Myelofibrosis
B) Myeloid depletion
, C) Reconversion
D) Marrow replacement - correct answer ✔✔C) Reconversion
Which of the following best describes the replacement of cells by metastatic cells?
A) Myelofibrosis
B) Myeloid depletion
C) Reconversion
D) Marrow replacement - correct answer ✔✔D) Marrow replacement
Which of the following best describes a loss of red marrow due to radiation or chemo?
A) Myelofibrosis
B) Myeloid depletion
C) Reconversion
D) Marrow replacement - correct answer ✔✔B) Myeloid depletion
Which of the following best describes replacement of marrow by fibrous tissue due to radiation
or chemo?
A) Myelofibrosis
B) Myeloid depletion
C) Reconversion
D) Marrow replacement - correct answer ✔✔A) Myelofibrosis
T/F: A diffuse increase in bone density on plain film and CT will appear as a generalized overall
whiteness (sclerosis)of bone with diffuse loss of visualization of normal network of bony
trebeculae and loss of visualization of the normal cortico-medullary junction - correct answer
✔✔true
