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
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.,...
The PET/CT scan can be also performed earlier or later during the course of treatment in case of clinical deterioration and/or suspicious progression on contrast- enhanced CT. – Before immunotherapy discontinuation In patients receiving maintenance therapy or undergo- ing long-term ...
Diagnostic CT scan: A CT scan that typically involves higher X-ray doses than a low-dose CT scan with the option of using oral or intravenous contrast. It is recommended that diagnostic CT scans be conducted in alignment with local consensus protocols or established national guidelines. Low-dos...
The 1816 A Bard coaxial biopsy needle was used to stepwise insert into the biopsy target area, and CT scan was used to fuse with 18 F-FDG PET through the built-in VMI software to confirm that the needle tip was located in the most metabolically active area. The needle core was ...
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 ...
CT scan can be acquired with variable parameters (e.g., mAs, kVp, pitch, with or without contrast) to suit the clinical need or according to local protocols and regulations, for instance using a low-dose, low-resolution CT scan only for attenuation correction and anatomical localization, or...
Patients will be placed in the supine position with both arms raised above their head. Our standard clinical PET/DECT protocol includes a non- breath-hold contrast-enhanced DECT scan with the arms down for attenuation correction, acquired from the top of the skull through the inguinal region, ...
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 ...
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 ...
