Early localization of biochemical recurrence in patients after radical treatment of prostate cancer is a widely accepted clinical indication of (11)C-choline PET/CT. Its widespread clinical use has prompted the depiction of incidentalomas, unusual sites of metastatic lesions, as well as false positive and negative cases. Over the last 6 years, a total of(More)
We present here results on the labelling of red blood cells with 99mTc-HMPAO as an alternative method to the usual in vitro technique. Anticoagulant agents, the labelling medium with plasma, and the lapse of time between 99mTc-HMPAO preparation and labelling are the main factors which affect the efficiency of the procedure. A 93.9 +/- 2.3% labelling yield(More)
Bone scintigraphy has been used extensively in prostate cancer patients to detect bone involvement. (11)C-choline PET/CT is indicated when a biochemical recurrence is suspected, as this procedure is able to detect local recurrence, lymph-node infiltration, and metastases.In cases where the results of these 2 procedures do not coincide, MRI is then usually(More)
We report a case of a patient with lung adenocarcinoma and bone and extraosseus metastases studied with (18)F-FDG PET-CT, (99m)Tc-HMDP and (18)F-fluoride PET-CT. It assesses the usefulness of (18)F-FDG PET-CT for initial staging of the disease and monitoring response to therapy. For the study of the sclerotic bone metastases it shows the superiority of(More)
The current protocols include the bone scintigraphy and choline PET/CT to localize recurrence in patients having elevated serum PSA after treatment for prostate cancer. Both methods show good agreement in the diagnosis of bone metastases, however conflicting results can be found. We present three cases in which a PET/CT was performed with (18)F-Fluoride due(More)
Tracheobronchial tree is reported to harbor benign processes like inflammatory origin, foreign bodies, pulmonary aspirations, mucous plugs and benign tumors (most of them of mesenchymal origin), as well as malign processes: primary (of epithelial origin), and secondary (by direct infiltration or hematogenous spread).1,2 We report a patient with history of(More)
Varón de 57 años diagnosticado a finales del año 2003 de carcioma escamoso de hipofaringe (T3N2M0), tratado mediante radioerapia y quimioterapia con respuesta completa. En el transcurso e siete años presentó dos episodios de recurrencia local, la última ace tres años, que fue tratada mediante cirugía y radioterapia. En un estudio RM de control se visualizó(More)
CLINIC PROBLEM AND CASE SERIES To assess the diagnostic usefulness of (11)C-choline PET/CT vs. multi-parametric MRI in the prostate cancer relapse. A retrospective study of 21 patients with prostate cancer treated initially with surgery (n=12), radiotherapy (n=9). PSA levels were increased (post-surgery: .3-3.6 ng/ml; post-radiotherapy: 2.4-8.8 ng/ml). In(More)
