Ga prostate-specific membrane antigen (PSMA) PET/CT is increasingly used to evaluate extent of disease in prostate carcinoma. Several other benign and malignant pathologies have also been reported to demonstrate PSMA avidity. We present a case of serous cystadenoma of the pancreas showing focal uptake on PSMA PET/CT.
Ga prostate-specific membrane antigen (PSMA) PET/CT is increasingly used to evaluate extent of disease in prostate carcinoma. We present a case of subacute cortical cerebral infarct showing focal uptake on PSMA PET/CT. It is an important potential cause of false-positive uptake in this imaging cohort. The patient is an 85-year-old man with a background of… (More)
The brain derived neurotrophic factor (BDNF) val66met polymorphism rs6265 influences learning and may represent a risk factor for schizophrenia. Healthy people with high schizotypal personality traits display cognitive deficits that are similar to but not as severe as those observed in schizophrenia and they can be studied without confounds of… (More)
Ga-DOTATATE PET/CT is increasingly used to image somatostatin receptor expressing tumors. Various intracranial tumors including medulloblastoma are known to express somatostatin receptors. We present a case of incidental cerebellar medulloblastoma on a staging Ga-DOTATATE PET/CT for appendiceal carcinoid.
Ga prostate-specific membrane antigen PET/CT is increasingly used to evaluate extent of disease in prostate carcinoma. Parenchymal brain metastases originating from prostate cancer have highly variable imaging appearance. We present a 77-year-old man with cerebellar metastasis from prostate cancer showing focal uptake on prostate-specific membrane antigen… (More)
O-(2-fluoroethyl)-L-tyrosine (FET) PET/CT is a promising imaging modality for brain tumor imaging because of its reported high sensitivity for biologically active tumor tissue. We present a case of biopsy-proven neurosarcoidosis showing FET uptake. It is an important cause of false-positive uptake on FET PET/CT.
Metastatic neureoendocrine tumor to bone is well recognized. Typically, this has an appearance of multiple focal lesions. We present an example of diffuse skeletal involvement on both F-FDG PET/CT and Ga DOTATATE PET/CT with a pattern similar to the superscan appearance described on skeletal scintigraphy.
