[Chilean experience with the use of 18F-deoxyglucose positron emission tomography].

Background: Clinical oncology is the main application of 18F-deoxyglucose (FDG) positron emission tomography (PET).

Aim: To evaluate the first 1,000 patients studied with FDG PET in Chile.

Material And Methods: Retrospective analysis of 1,000 patients (aged between 1 and 94 years, 550 females) studied with FDG PET, since 2003.

[Use of positron-emission tomography with F18-fluorodeoxyglucose for the assessment of lung lesions suspicious of malignancy].

Positron-emission tomography (PET) with F18-fluorodeoxyglucose (FDG) is very helpful in the evaluation and management of lung lesions. It is specially useful for the characterization of solitary nodules, for the staging, evaluation of recurrence and therapeutic response in non-small cell lung cancer, for the evaluation of small cell lung cancer and for the assessment of pulmonary metastases. This article is a literature review on PET with FDG in lung cancer.

[Fluorodeoxiglucose F18 positron emission tomography imaging (F18FDG) for the assessment of rising levels of serum CA 19-9 in pancreatic mucinous cystadenocarcinoma. Report of one case].

We report a 38 year old female patient with a pancreatic mucinous cystadenocarcinoma. She presented at the onset with a peritoneal rupture that required emergency surgery. Five months later, the patient was subjected to a segmental pancreatectomy and splenectomy.

The predictive value of 201Tl rest-redistribution and 18F-fluorodeoxyglucose SPECT for wall motion recovery after recent reperfused myocardial infarction.

Unlabelled: 201Tl and 18F-FDG are useful for acute myocardial infarction (MI) assessment. The goal of this study was to compare their predictive value for wall motion recovery in the culprit area after a recent reperfused MI using SPECT technique.

Methods: Forty-one patients (mean age: 56 +/- 12 years) were included, 81% of them male; all were studied within 1-24 days post MI.

[Clinical application of positron emission tomography (PET)].

Functional imaging using PET (positron emission tomography) has a great impact on current medical practice. It allows to explore, in a very precise way, different processes such as tissue flow and metabolism. Fluor-deoxyglucose labeled with F18 fluorine represents glucose metabolism.

[Performance of Thallium 201 rest-redistribution spect to predict viability in recent myocardial infarction].

Background: The detection of viability after acute myocardial infarction is primordial to select the most appropriate therapy, to decrease cardiac events and abnormal remodeling. Thallium201 SPECT is one of the radionuclide techniques used to detect viability.

Aim: To evaluate the use of Thallium201 rest-redistribution SPECT to detect myocardial viability in reperfused patients after a recent myocardial infarction.
