Background: Positron emission tomography (PET) has been shown to be cost effective for the staging of stage I and II breast cancer, recurrent colorectal cancer and non small cell lung cancer. This study determines a required catchment size for the management of these three cancers based on a breakeven analysis.
Material/methods: Cost effectiveness analysis is used to determine the cost savings of introducing PET into the diagnostic algorithm for the staging of stage I and II breast cancer, recurrent colorectal cancer and non small cell lung cancer. The cost savings for these cancers are used to calculate a required catchment area for the installation of a PET center with cyclotron.
Results: The aggregate estimated "breakeven" cost of a PET study would be dollars 2195, well below the expected cost per study. In order to break even, each PET device would require 740 new cases per year. For a general representative population, one person per 766 may benefit from a PET scan if a PET study was included in the diagnostic algorithm for all three cancers. Finally, a calculated catchment size of 567,000 people would support the use of a PET center with cyclotron
Conclusions: The use of PET for the staging of cancer appears to be cost effective in most jurisdictions in Canada.

Objective: Arterial sampling for PET imaging often involves continuously measuring the radiotracer activity concentration in blood using an automatic blood sampling system (ABSS). We proposed and validated an external delay and dispersion correction procedure needed when a change in flow rate occurs during data acquisition. We also measured the external dispersion constant of [11C]CURB, [18F]FDG, [18F]FEPPA, and [18F]SynVesT-1.

Solitary axillary lymph node metastasis from ovarian cancer is rare. A 74-year-old woman who had undergone hysterectomy and bilateral salpingo-oophorectomy for ovarian cancer 2 years ago presented to our hospital with enlarged axillary lymph node. 18F-FDG PET/CT revealed left axillary lymphadenopathy with an SUVmax of 8.

Neoplastic meningitis, also known as leptomeningeal metastases, is a rare clinical entity seen in less than 1%-2% of primary nervous system tumors. Diagnosis of leptomeningeal metastases is difficult and is achieved by cytologic evidence of malignant cells in cerebrospinal fluid, or demonstration of radiologic abnormality. 18F-FDG PET/CT can detect leptomeningeal metastases before anatomical changes.

We present the case of a 60-year-old man admitted to the hospital presenting with high FUO (fever of unknown origin), strong headache, face erythematous-desquamative cutaneous lesions, long history of abdominal pain, and diffuse myalgia. He was also previously treated with immunosuppressants and currently managed with corticosteroids for a seronegative rheumatic disease. Given the immunocompromised state, an infective etiology was suspected.

Subcutaneous nodules and masses as the primary manifestation of diffuse large B-cell lymphoma are exceedingly rare. We present 18F-FDG PET/CT findings of multiple hypermetabolic nodules and masses distributed throughout the body, creating a characteristic "leopard man" appearance on the MIP image, in a 65-year-old man. An excisional biopsy of the right thigh mass confirmed the diagnosis of diffuse large B-cell lymphoma.
