1) Patients with benign and early stage malignant ovarian tumors who were confirmed by surgery or pathological biopsy; 2) patients who had received plain CT (P-CT) and contrast-enhanced CT (CE-CT) scan before surgery or puncture. 3) Patients with no history of relevant treatments (e.g.,...
To compare the performance of [18F]FDG and [18F]FAPI-04 in PET/CT evaluation for liver cancer lesions, with a further exploration of the associations between PET semiquantitative data and immunohistochemical markers to liver cancer. Patients with suspect
7). In contrast, FDG uptake in the myocardium can decrease in patients with LVH if the metabolic remodeling proceeds as structural remodeling in the form of LVH. The decrease in diastolic function leads to a decline in FDG uptake. The reduction of FDG uptake in progressive LVH that is ...
Patients undergoing PET scans may experience nausea and vomiting. These symptoms can be associated with the contrast dye used for the CT part of the scan. Headache: Some individuals might experience headaches as a result of the contrast dye or other factors related to the scan. ...
When a diagnostic CT scan with intravenous contrast agent enhancement is to be performed as part of the FDG PET/CT study, indications, contraindications and restrictions have to be assessed by a qualified physician. Medication that interacts with intravenous contrast agent (e.g. metformin for the ...
After PET acquisition, a diagnostic CT scan was conducted for radiological diagnostic purposes. An eGFR > 30 mL/min/1.73 m2 was required for intravenous contrast. The scan was performed at 120 kVp using dose modulation, SmartmA at noise index 24, pitch 0.984, and reconstructed with the iterati...
IV flush with 10 mL, start scan 30–40 s post injection. The arrows are pointing towards the increased visualization of the vessels with the different contrast application regimes. Similar window-level settings are applied to all CT-slices. In man, typically, a whole-body CT can be ...
If there were uncertainties or if the puncture needle was not visible (e.g., due to significant respiratory excursion), a control CT scan could be performed at any time. Three gastropexies (2 cm apart) were mandatory before wire placement with an 18 G needle, dilatation, and tube ...
On the day of the scan, body weight was measured and non-fasted animals were anesthetized for 8 ± 2 min with a mixture of oxygen (95%) and isoflurane (5% for induction and ≤ 2% for maintenance). A small drop of blood was collected for measuring blood glucose levels. Animals then rec...
If a diagnostic CT scan using contrast was routinely performed as part of the PET/CT examination, it was performed after the PET scan. All patients fasted for at least 6 h before the injection of 4.5 MBq/kg of FDG. Serum glucose level measured before injection of the radiotracer was less...
