Q.Freeze helps increase staging accuracy
Reconstruction: VUE Point HD with SharpIR*
Post injection time: 63 min
- Standard:1.5 min/bed
Dose: 260 MBq of 18F-FDG
Whole-body acquisition for localization and attenuation purpose.
4D acquisition both for CTAC and diagnosis.
Patient treated surgically for a left colon adenocarcinoma followed by several chemotherapy cycles.
After 2 years, an increase of the serum marker ( GICA 76 U/ml) is noticed. Patient submitted to contrast enhanced CT with a suspicious relapse in the colon hepatic flexure. The colonoscopy showed tubular polypoid lesion with moderate dysplasia. No other pathological findings were found.
Patient submitted the for PET/CT for staging of the disease.
Small focus uptake area localized on the gastric wall difficult to classify .
Several mismatch artifacts due to the patient breathing on the abdominal area.
The focal uptake area is clearly localized in the pancreatic tail as well
as new pathological uptake area corresponding to a peritoneal nodule.
After the motion correction performed by the Q.Freeze technology
the localization of the lesion and extent of the
disease is confirmed. Correctly localizing the metastasis benefited the patient with a more accurate staging.
