AIM To evaluate the effect of the 18F-FDG PET-CT respiratory gating (4D) study in the correct documentation of pulmonary lesions with faint uptake in standard PET-CT. METHODS Forty-two pulmonary lesions with a low or no detectable uptake of FDG (SUV(max) < 2.5) in 3D PET-CT were prospectively evaluated in 28 patients (19 males and 9 females), mean age(More)
AIM To analyze the costs of Fever of Unknown Origin (FUO) prior to the PET-CT study. To determine the effectiveness of PET-CT in the diagnosis of FUO. A proposal of diagnostic algorithm. MATERIAL AND METHODS A retrospective study was performed that included 20 patients who had been studied between January 2007 and January 2011, with a mean age of 57.75(More)
OBJECTIVE To obtain correct location of occult breast lesions by radiopharmaceutical methods.

We present three cases of patients with prostate carcinoma who underwent total body bone scintigraphy with 99mTc-Hydroxymethylene diphosphonate (99mTc-HMDP), showing myocardial uptake. Complementary diagnostic examinations were performed in these patients: cardiac (electrocardiogram and echocardiography), analysis of plasma electrolytes, including calcium,(More)
OBJECTIVE The aim of our work was to assess the diagnostic impact of 123-I Ioflupane SPECT in patients with tremor and some other sign of Parkinsonisms in regards to its categorization in Parkinsonisms with involvement/indemnity of presynaptic dopaminergic neurons as well as to establish a differential diagnosis between essential tremor (ET) and(More)
