SLNB

Sentinel lymph node biopsy

2

Sentinel lymph node biopsy

The removal of the sentinel lymph node to see if it contains cancer

3

What is sentinel lymph nodes?

Is the first lymph node in a chain or cluster of lymph nodes that receives lymph fluid from the area around a tumour

4

What will most likely spread to sentinel lymph nodes?

Cancer

5

What is another term for sentinel lymph node biopsy?

Sentinel lymph node dissection
- SLND

6

What are 4 examples of new technologies?

1. Spatial Compound Imaging
- SonoCT
2. Sonoelastography
3. Elastography
4. 3D and 4D

7

Spatial Compound Imaging

Views the target area from multiple lines of sight to form an image that has fewer artifacts

8

How does spatial compound imaging work?

Several overlapping scans are acquired from different angles then averaged and combined to form a compound image

9

Elastography

Imaging the strain induced in breast tissue following compression with a small mechanical device or transducer

10

What is normal breasts composed of?

Glandular tissue
- which is firmer than connective tissue which is firmer than fat

11

How do pathologies disrupt normal tissue patterns?

With stiff, dense, inelastic tissue

12

What are poorly seen sonographically?

Benign lesions

13

How are malignant lesions seen as? (2)

1. Larger
2. Hard

14

What does 3D imaging acquire?

Image data from many different planes, storing the data in memory, then manipulating the data with computer software

15

4D

3D with real time scanning capability

16

What are potential benefits of 3D scanning? (6)

1. Visualization of infiltrative zone in coronal plane
2. Tumour surface imaging
3. Analyze data blocks
4. Rotate the 3D image
5. Estimation of tumour volume
6. Monitor tumour size post therapy

17

6. Skin retraction

25

Vascularity (3)

1. Present or not present
2. Adjacent to lesion
3. Diffusely increased

26

Miscellaneous (5)

1. Clustered microcysts
2. Complicated cysts
