What is lymphiscintigraphy?
Lymphoscintigraphy (sentinel lymph node mapping) is an imaging technique used to identify the lymph drainage basin, determine the number of sentinel nodes, differentiate sentinel nodes from subsequent nodes, locate the sentinel node in an unexpected location, and mark the sentinel node over the skin for biopsy.
A sentinel node is?
It is the first node in which the lymphatic drainage occura in a particular area.
What is sentinel node?

What distinguishes a sentinel node from other nodes?
A sentinel lymph node is the first lymph node that drains a cancer. If a cancer has not spread to the first draining lymph node near a cancer, there is a high likelihood it has not spread elsewhere.
What is the significance of sentinel lymph node?
A sentinel lymph node is the first lymph node that drains a cancer. If a cancer has not spread to the first draining lymph node near a cancer, there is a high likelihood it has not spread elsewhere.
What node biopsy is performed a the beginning of the treatment of breast cancer?
sentinel
Can you delete the head node from doubly linked list?
If by 'head node' you simply mean the first node, then yes; but if 'head node' means the special element which is not supposed to ever be deleted (aka sentinel node), then no.
What is sentinel lymph node mapping and biopsy?
A new technique called sentinel lymph node mapping and biopsy often eliminates the need for removing some or all lymph nodes by testing the first lymph node for cancer.
How do you usually indicate the end of a linked list?
The last node typically points to NULL (meaning there is no next node). Some implementations make use of a sentinel node as this can make it easier to implement some algorithms (because the sentinel always exists even when the list is empty). In such implementations, both the head and the tail node may be sentinels.
What is learned by the procedure known as sentinel node mapping?
These sentinel nodes are thus identifiable and are the most likely to harbor any regional metastatic disease. If these nodes alone are biopsied and are normal, the rest of the lymph node group can be spared.
What kind of biopsy is performed at the beginning of breast cancer treatment?
Sentinel-node biopsy
What is most important in stage determination and regional lymph node involvement?
Of primary importance to stage determination and regional lymph node involvement is identification and analysis of the sentinel lymph node.
