Lymph Node Staging Flashcards
1
Q
Soultani, VRU, 2017:
CT indirect lymphography in canine mammary gland tumors
- What had the highest sensitivity, specificity and accuracy for detection of neoplastic invasion of the sentinel lymph node?
- What Hounsfield units value in the center of the sentinel lymph node 1min after contrast injection provided significant sensitivity, specificity and accuracy for sentinel lymph node metastasis?
A
Soultani, VRU, 2017:
- Absence of opacification or heterogenous opacification 1min after contrast injection had the highest sensitivity, specificity and accuracy for detection of neoplastic invasion of the sentinel lymph node
- A value of <444 Hounsfield units in the center of the sentinel lymph node 1min after contrast injection provided significant sensitivity, specificity and accuracy for sentinel lymph node metastasis

Q
Grimes, VRU, 2017:
Indirect CT lymphangiography for tumors of the head
- In what % of dogs was the sentinel lymph node successfully identified within 3mins of contrast injection?
- What delayed or prevented identification of sentinel lymph nodes in 11% of the dogs?
A
Grimes, VRU, 2017:
- The sentinel lymph node was successfully identified within 3mins of contrast injection in 89% of the dogs
- Compression of lymphatic vessels from ET tube ties and/or the patient’s own body weight delayed or prevented identification of sentinel lymph nodes in 11% of the dogs

Q
Rossi, VRU, 2018:
CT-lymphography for lymph node staging
- What % had maximal Hounsfield units in the respective region of interests 1min after contrast injection?
- What % of primary draining lymph nodes showed homogenous contrast enhancement following IV contrast enhancement?
- Primary draining lymph nodes were successfully identified after local injection of contrast in what % of cases?
- What % of primary draining lymph nodes corresponded to the anatomical lymph node(s)?
- What % had multiple draining lymph nodes?
- What % of cytologically positive lymph nodes were contrast enhancing on CT-lymphography?
A
Rossi, VRU, 2018:
- 51% had maximal Hounsfield units in the respective region of interests 1min after contrast injection
- 100% of primary draining lymph nodes showed homogenous contrast enhancement following IV contrast enhancement
- Primary draining lymph nodes were successfully identified after local injection of contrast in 60% of cases
- 78% of primary draining lymph nodes corresponded to the anatomical lymph node(s)
- 27% had multiple draining lymph nodes
- 44% of cytologically positive lymph nodes were contrast enhancing on CT-lymphography
