    Low-carbohydrate diet versus euglycemic hyperinsulinemic clamp for the assessment of myocardial viability with F-18-fluorodeoxyglucose-PET: a pilot study
    (2014) SOARES JR., Jose; RODRIGUES FILHO, Filadelfo; IZAKI, Marisa; GIORGI, Maria Clementina P.; CATAPIRRA, Rosa M. A.; ABE, Rubens; VINAGRE, Carmen G. C. M.; CERRI, Giovanni G.; MENEGHETTI, Jose Claudio
    Positron emission tomography with F-18-fluorodeoxyglucose (FDG-PET) is considered the gold standard for myocardial viability. A pilot study was undertaken to compare FDG-PET using euglycemic hyperinsulinemic clamp before F-18-fluorodeoxyglucose (F-18-FDG) administration (PET-CLAMP) with a new proposed technique consisting of a 24-h low-carbohydrate diet before F-18-FDG injection (PET-DIET), for the assessment of hypoperfused but viable myocardium (hibernating myocardium). Thirty patients with previous myocardial infarction were subjected to rest Tc-99m-sestamibi-SPECT and two F-18-FDG studies (PET-CLAMP and PET-DIET). Myocardial tracer uptake was visually scored using a 5-point scale in a 17-segment model. Hibernating myocardium was defined as normal or mildly reduced metabolism (F-18-FDG uptake) in areas with reduced perfusion (Tc-99m-sestamibi uptake) since F-18-FDG uptake was higher than the degree of hypoperfusion-perfusion/metabolism mismatch indicating a larger flow defect. PET-DIET identified 79 segments and PET-CLAMP 71 as hibernating myocardium. Both methods agreed in 61 segments (agreement = 94.5 %, kappa = 0.78). PET-DIET identified 230 segments and PET-CLAMP 238 as nonviable. None of the patients had hypoglycemia after DIET, while 20 % had it during CLAMP. PET-DIET compared with PET-CLAMP had a good correlation for the assessment of hibernating myocardium. To our knowledge, these data provide the first evidence of the possibility of myocardial viability assessment with this technique.

    Influence of the arm position in myocardial perfusion imaging acquisition
    (2014) IZAKI, Marisa; SOARES JUNIOR, Jose; GIORGI, Maria Clementina Pinto; MENEGHETTI, Jose Claudio
    Objective: despite the technologic advances in myocardial perfusion imaging, we keep using an uncomfortable and sometimes impracticable patient position - supine with arms raised above the head (U). The purpose of this study was to investigate whether perfusion and functional cardiac gated SPECT scan results of acquisition U are equivalent to another position modality: supine with arms down at the sides of the trunk (D). Methods and Results: we performed U acquisition and in sequence D acquisition in 120 patients (pts) using a one-day MPI (rest-gated/stress), with 99mTc-sestamibi (370 MBq and 1110 MBq). Images were processed by the iterative reconstruction method (OSEM). Rest (R) and stress (S) studies were scored using 17-segments model. Functional parameters (left ventricular ejection fraction, and volumes) were automatically obtained by the quantitative gated SPECT (QGS) program. According to the degree of stress defects observed in U study, the patients were categorized in two subgroups: normal (SSS <= 3 or < 5%) and abnormal (SSS > 3 or >= 5%). Shoulder/back pain occurred in 23.3% of U patients and in 5% of D. No significant differences between U and D were found for SSS (p = 0.82) and SRS (p = 0.74) in normal group. In abnormal group, good correlation was found between U and D modes for SSS (Rho = 0.95, p = 0.0001) and SRS (Rho = 0.96 p = 0.0001), but the mean SSS (12.53 +/- 7.54) and SRS (10.60 +/- 7.08) values of D were significantly lower (p < 0.05) than SSS (13.43 +/- 6.81) and SRS (11.33 +/- 6.97) of U mode. Function measurements presented good correlations, except for end-diastolic volume (p = 0.0001). Conclusion: although D mode appears to be more comfortable and presented a good correlation with U values of SSS and SRS, in abnormal pts, the extent and severity of defects can be underestimated. Considering clinical implications of an accurate perfusion measurement, the acquisition with the arms down should be avoided.
