CAT cardio05

18F-FDG CARDIOLOGIC PET-CT

DESCRIPTION: Study of the metabolism of cardiac glucose, completing myocardial perfusion studies.

PREPARATION: 6-hour fasting. Intense physical exercise must be avoided 24 hours before the study. An insulin clamp or oral glucose overload must be performed.

INDICATIONS: Study of myocardial viability.

DURATION OF PROCEDURE: 2 hours.

CAT neuro02

18F-FDG BRAIN PET-CT

DESCRIPTION: Study of brain glucose metabolism.

PREPARATION: 4 to 6-hour fasting. Patients should take the usual medication. There is the possibility of withdrawing the psychotropic drugs. Diabetic patients should take their usual medication. If needed, sedation will be performed 20 minutes after the administration of FDG, preferably before images acquisition, according to the anesthesia procedure.

INDICATIONS: Early diagnosis and differential diagnosis of dementias. Study of movement disorders, for the characterization of atypical parkinsonisms. Delimitation of the epileptographic focus of the interictal phase in epilepsy. Evaluation of some psychiatric disorders (schizophrenia, depression, obsessive-compulsive disorder). Evaluation of cranioencephalic traumatisms and cerebrovascular pathologies.

CAT onco03

18F-FDG ONCOLOGIC PET-CT

DESCRIPTION: Study of the disease in oncologic patients.

PREPARATION: 6-hour fasting of at least 6 hours before performing the procedure is required. In general, it is advisable that patients take a light meal the night before the study and that they do not ingest anything until after it has been done. On the day of the procedure, the patient will have to drink abundant water (0.5-1L). Juices, sugary solutions, sweets, etc. are not allowed. Urine must not be retained. Intravenous glucose solutions should also interrupt at least 6 hours before the scheduled time of the procedure. Patients should take their usual medication. It is necessary to avoid doing physical exercises 2-3 days before the procedure since this could condition a high muscular uptake of the tracer. Diabetic type II and hyperglycemic patients treated with oral antidiabetic medicines should take their usual medication early in the morning and preferably stay in bed at night before performing the test. Type I or diabetic patients undergoing subcutaneous or intravenous insulin therapy should take their usual medication early in the morning. To avoid possible hypoglycemia, these patients can take some light breakfast, with a minimum of 4 hours before the procedure.

INDICATIONS: Characterization of pancreatic masses. Detection of lung pulmonary nodules and evident tumors of unknown origin. Detection of recurrences of gliomas with a high degree of malignancy; head and neck tumors; differential thyroid cancer (high TG and negative RCI); primary lung carcinoma; breast, pancreatic, colorectal and ovarian carcinoma; malignant lymphomas; malignant melanomas and other carcinomas. Staging of malignant melanoma; locally advanced breast cancer; head and neck tumors; primary lung cancer; esophagus, pancreatic and colorectal cancer; malignant lymphomas. Monitoring of the response to the treatment of malignant lymphomas and head and neck tumors.
