Abstract

Aims and objectives Methods and materials Results Conclusion Personal information References, Aims and objectives: With delivery FDG, the radiation dose is constant at calibration time but the actual dose given varies with the preset PET scan time point. Eventually, it is infeasible to keep the dose per weight constant unlike the case with cyclotron-produced...

Author

Abstract

The aim of this study was to assess the physiological uptake of 18F-fluoro-2-deoxyglucose (FDG) by an apparently normal testis with combined positron emission tomography–computed tomography (PET/CT) and its correlation with age, blood glucose level, and testicular volume. The testicular uptake of 18F-FDG, expressed as the standardized uptake value (SUV), was measured on PET/CT images in 203 men. The correlation between SUV and age, blood glucose level, and testicular volume was assessed. The SUV in the total of 406 testes was 2.44 ± 0.45 (range 1.23–3.85). The SUV was 2.81 ± 0.43 (2.28–3.85) for 30–39 years ( n = 12), 2.63 ± 0.45 (1.77–3.75) for 40–49 years ( n = 64), 2.46 ± 0.35 (1.44–3.15) for 50–59 years ( n = 82), 2.51 ± 0.41 (1.50–3.46) for 60–69 years ( n = 86), 2.43 ± 0.47 (1.42–3.29) for 70–79 years ( n = 86), and 2.18 ± 0.45 (1.23–3.03) for 80–89 years ( n = 76). When we calculated the mean SUV of bilateral testes in each patient, there were significant statistical differences between those in the age group of 30–39 years and 80–89 years, 40–49 years and 80–89 years, and 50–60 years and 80–89 years, when using an unpaired test with Bonferroni correction. The laterality index (|L − R|/(L + R) × 2) in 203 men was 0.066 ± 0.067 (0–0.522). There was a mild correlation between the mean SUV and age ( r = −0.284, P < 0.001) as well as between the mean SUV and mean volume ( r = +0.368, P < 0.001). There was no correlation between the mean SUV and glucose blood level ( r = −0.065, P = 0.358). Some uptake of FDG is observed in the normal testis and declines slightly with age. Physiological FDG uptake in the testis should not be confused with pathological accumulation. [ABSTRACT FROM AUTHOR]

Abstract

Objective: The purpose of this study was to compare the predictive capabilities of diffusion-weighted MRI (DWI) and 18F-FDG PET/CT for tumor response to therapy and survival in patients with non-small cell lung cancer (NSCLC) receiving chemoradiotherapy., Subjects and Methods: The study included 64 patients with NSCLC diagnosed as stage III who underwent pretherapeutic DWI and FDG PET/CT and were treated with chemoradiotherapy. For quantitative prediction, apparent diffusion coefficient (ADC) for DWI and maximum standardized uptake value (SUVmax) for PET/CT were measured at all targeted lesions and averaged to obtain final values for each patient. To evaluate the predictive capability of either index for distinguishing partial response and nonresponse (stable or progressive disease) groups, receiver operating characteristic analysis was performed, and sensitivity, specificity, and accuracy of the two modalities were compared using the McNemar test. Finally, overall and progression-free survival curves divided by the corresponding threshold value were compared by means of the log-rank test., Results: The area under the curve (Az) for ADC (Az=0.84) was significantly larger than that for SUVmax (Az=0.64, p<0.05). The application of feasible threshold values resulted in specificity (44.4%) and accuracy (76.6%) of DWI becoming significantly higher than those of PET/CT (specificity, 11.1%; p<0.05 and accuracy, 67.2%, p<0.05). In addition, only overall survival and progression-free survival of the two groups divided by ADC at 2.1×10(-3) mm2/s and SUVmax at 10 showed a significant difference (p<0.05)., Conclusion: DWI may have better potential than FDG PET/CT for prediction of tumor response to therapy in NSCLC patients before chemoradiotherapy.

Abstract

Background and Objectives: Recently, early mobilization and discharge after cardiac surgery have been recommended. However, many patients are anxious about returning to daily life soon after undergoing heart operations. To resolve this problem, an individualized rehabilitation plan for each patient is important. Rehabilitation programs must estimate the level of cardiac function in daily life. This study evaluated self-measurements of heart rate and blood pressure during home-based exercise training., Methods: Thirty-six patients, 28 men and 8 women (mean age 58 +/- 19 years) who underwent cardiac operations were enrolled in this study. None of the patients experienced postoperative complications. Changes in heart rate and blood pressure during daily activities at home were measured by the patients. This data was then used to plan individual rehabilitation programs., Results: The blood pressure rose from 114 +/- 17 to 139 +/- 21 mmHg (mean increase of 25 +/- 15 mmHg) when the patients were asked to walk up and down a set of stairs. Thirteen patients (36%) exhibited an increase in blood pressure of 30 mmHg or more while ascending the stairs. The patients' blood pressure returned to its pre-exercise level after 5 min. The heart rate rose from 84 +/- 15 to 113 +/- 14 beats/min (mean increase of 29 +/- 8 beats/min) during the exercise. During the home-based training period, the maximum blood pressure was 133 +/- 22 mmHg, and the maximum heart rate was 97 +/- 13 beats/min., Conclusions: The patients were very careful during their trial outpatient period, as this was their first post-cardiac surgery experience. Consequently, the degree of exercise at home was even more mild than in hospital. Self-measurement of heart rate and blood pressure was feasible. By referring to these measurements, the patients were able to monitor and increase their level of exercise. This post-cardiac surgery rehabilitation program is helpful for early returning to daily life activities.
