Summary
Preoperative CT-lymphography (CTLG) effectively visualizes sentinel lymph nodes (SLN) and lymphatic drainage. This technique aids in determining the extent of lymph node dissection, particularly for head and neck tumors.
Area of Science:
- Medical imaging
- Surgical oncology
- Diagnostic radiology
Background:
- Sentinel lymph node (SLN) biopsy is crucial for cancer staging.
- Current SLN identification methods include radioisotopes and blue dyes.
- A combined approach using 99mTc-phytate, patent blue V dye, and preoperative CT-lymphography (CTLG) is utilized.
Observation:
- CTLG involves intradermal injection of a contrast agent (Iomeprol) around the tumor.
- CT imaging is performed using a 64-row MDCT system.
- The study included 34 patients undergoing CTLG between September 2008 and March 2013.
Findings:
- CTLG successfully visualized SLN and lymphatic drainage in 21 out of 34 patients.
- The technique allows for clear detection of SLN and lymphatic flow near tumors.
- No significant "shine-through" effect was observed, enhancing visualization.
Implications:
- CTLG offers a valuable method for SLN navigation, especially in head and neck regions.
- This imaging modality can assist in precisely defining the scope of lymph node dissection.
- CTLG may improve surgical planning and patient outcomes in oncologic procedures.
