Posterior Layering of Fluorine-18 Fluorodeoxyglucose in the Urinary Bladder

layering of excreted 18 F - FDG in the urinary bladder in patients with urinary tract infection and distended bladder

Preliminary assessment of fluorine-18 fluorodeoxyglucose positron emission tomography in patients with bladder cancer.

The purpose of this study was to assess the feasibility of imaging of bladder cancer with fluorine-18 fluorodeoxyglucose positron emission tomography (FDG-PET) scanning. We studied 12 patients with histologically proven bladder cancer who had undergone surgical procedures and/or radiotherapy. Retrograde irrigation of the urinary bladder with 1000-3710 ml saline was performed during nine of the ...

PHEOCHROMOCYTOMA OF THE URINARY BLADDER

One of the rarest tumors involving the urinary bladder is the pheochromocytoma. A case of pheochromocytoma of the urinary bladder in a young female suffering from headache and cystitis for many years is reported. Twenty-four hour urine VMA was normal. The patient was never hypertensive except during surgical manipulation of the tumor. Biopsy of the bladder resulted in massive hemorrhage.

Interesting Layering of Excreted 18F-FDG in the Urinary Bladder in Patients with Urinary Tract Infection and Distended Bladder.

Settling of (18)F-FDG in the bladder is often noted on whole-body PET/CT images, but this phenomenon has never received any careful attention and the mechanism has been unclear. The 2 patients described in this report, one with a T1 pathologic fracture and another with widespread bone and lymph node metastases from an unknown primary tumor, underwent PET/CT. Both had urinary tract infection and...

Clinical value of fluorine-18α-methyltyrosine PET in patients with gliomas: comparison with fluorine-18 fluorodeoxyglucose PET

BACKGROUND We investigated the relationship between metabolic activity and histological features of gliomas using fluorine-18α-methyltyrosine (18F-FAMT) positron emission tomography (PET) compared with fluorine-18 fluorodeoxyglucose (18F-FDG) PET in 38 consecutive glioma patients. The tumor to normal brain ratios (T/N ratios) were calculated, and the relationships between T/N ratio and World He...
