- Patient has given informed consent according to the International Conference on Harmonization (ICH) Good Clinical Practice (GCP) guidelines in accordance with the declaration of Helsinki.
Exclusion Criteria:
- Patient is planned for a treatment regimen which does not include standard surgical resection of the targeted lesion.
- Pregnant or actively lactating women.
- Blood glucose level ≥ 200mg/dl or more on the day of surgery.

実験的:intraoperative high-resolution PET-CT imaging of resected malignancy
|
Included patients are given a single weight-dependent activity of 18F-FDG at the department of Nuclear Medicine. After administration, patients are brought to the operating room where standard of care surgical removal of the malignancy is performed. The resected specimen(s) are brought to the imaging lab and scanned using a preclinical and/or a dedicated specimen PET/CT device. Following PET/CT imaging, the specimen is brought to the department of pathology, where it is sliced. Some of these slices are then rescanned using the preclinical PET/CT device. Moreover, frozen sections are made from one of these slices with macroscopically visible malignant tissue and placed on an autoradiograph overnight. Finally, the imaging results are then correlated to the results found during histopathological analysis of the specimens. |

|
Determine margin status in malignancies of the head and neck
時間枠:1 week after administration
|
To investigate the ability of high-resolution 18F-FDG-PET/CT-scan to determine the margin status in malignancies of the head and neck.
This will be compared to the gold standard of histopathological examination.

|
Characterize the ideal activity of 18F-FDG
時間枠:During data-analysis
|
The characterization of the ideal dose of 18F-FDG necessary for specimen imaging with a sufficient signal-to-noise ratio.
This dose will be identified using post-processing image reconstruction on the specimen resulting from patients given a standard diagnostic activity of 18F-FDG.

During data-analysis
|
|
Identify positive lymph nodes using 18F-FDG PET/CT
時間枠:1 week after administration
|
To investigate the ability of high-resolution 18F-FDG-PET/CT to identify positive lymph nodes excised by neck dissection.
This will be quantified as sensitivity and specificity compared to the gold standard of histopathological examination.
|
1 week after administration
|
|
Correlate distribution of 18F-FDG with histopathology
時間枠:1 day after administration
|
To correlate the distribution of 18F-FDG in and around tumoral tissue with the histopathology of the specimen.
This will be performed by correlating the results obtained from the PET/CT-scan of (sliced) tumoral specimens and autoradiography of a frozen section of the tumour.
