Radiation does not stay in the body with a CT scan: After a CT scan, no radiation remains in the body. On the contrary, a small amount of radiation may stay in the body for a short time after a PET scan. PET scans detect cancer earlier than other tests: Unlike other forms of imagi...
Objective:To compare the diagnostic accuracy of positron emission tomography/computed tomography(PET/CT)with contrast enhanced CT(CECT)alone in the initial evaluation of cervical lymph node of patients with head and neck cancer.Methods:Fifteen consecutive patients diagnosed with a head and neck cancer ...
PET/CT was performed in 60 patients with cancer after oral administration of barium, water, or mannitol-LBG. Qualitative and quantitative analyses were conducted to determine bowel distention and a potential influence of the contrast agents on the PET data. Intestinal distention with mannitol-LBG ...
Lymphoma was upstaged by PET/CT in 17% of the patients; with major changes in 12% of them and downstaged in 6% of the patients. Conclusion 18F-FDG PET/CT scan has a better diagnostic performance, represented by sensitivity, specificity, and accuracy, than CECT scan in the initial ...
This study sought to retrospectively evaluate whether combined 18F-FDG PET/CT with thoracic contrast-enhanced CT (CECT) helps in assessing primary cardiac tumors in adult patients, compared with CECT or PET/CT alone. Methods Forty-six consecutive patients who were diagnosed as primary cardiac tumors...
Pts with a diagnosis of DLBCL, FL, CLL/SLL, or MZL with PET/CT and contrast-enhanced CT studies performed at the Hospital of the University of Pennsylvania within 6 weeks of each other without intervening therapy were studied. Pts with clinically suspected progression of lymphoma between studies...
Aim of the study was to quantify the economic impact of PET/CT and contrast enhanced (c.e.) CT performed in a single session examination vs. stand-alone modalities in oncological patients. One-hundred-forty-five cancer patients referred to both PET/CT and c.e. CT, to either stage (N....
PURPOSE To compare the diagnostic performance of whole-body FDG PET-CT with that of contrast-enhanced CT (CE-CT) for assessment of resection stump recurrence after surgery in non-small cell lung cancer (NSCLC) patients. METHOD AND MATERIALS 98 consecutive NSCLC patients (58 males and 40 females...
The purpose of this study was to compare the ability of 18F-FDG PET/CT and contrast-enhanced MRI (CEMRI) to detect and grade venous tumour thrombus (VTT) and venous bland thrombus (VBT) in RCC and assess invasion of the venous wall by VTT. The PET/CT and
