Response was assessed by using the International Workshop Criteria (IWC) and revised criteria (IWC + PET) as well as the criteria of the European Organization for Research and Treatment of Cancer. One-way analysis of variance for repeated measures, receiver operator curve analysis, and Kaplan-Meier

curves were used for statistical analysis.\n\nResults: PET/CT performed at 2 months revealed complete (n = 12) or partial (n = 4) metabolic response in 16 of 23 patients with complete or partial clinical response. These findings were all confirmed at 6-month scanning. PET/CT indicated refractory or persistent disease at 2 and 6 months in the remaining seven patients. Better overall survival was observed for patients with a reduction in the maximum standard uptake value of 49% or higher (both at 2 and 6 months after RIT) when compared with those buy PD98059 with a decrease of less than 49% (P < .05).\n\nConclusion: Early assessment of response

to RIT by using PET/CT might be useful in the identification of patients needing additional therapeutic strategies. (C) RSNA, 2010″
“Objective. Selleck Dinaciclib – To investigate the accuracy in the estimation of the aortic lumen area and distensibility obtained from Steady-State Free-Precession (SSFP) and Phase Contrast (PC) MR sequences.\n\nSubjects and methods. – Systolic and diastolic aortic lumen of the ascending and descending aorta of 50 subjects. collected with both Anlotinib manufacturer acquisition sequences, were extracted using a 2D + t automated segmentation method.\n\nResults. – While the statistical study indicated very similar lumen areas for SSFP and PC data (slope = 1, r = 0.99), the corresponding distensibility values were less correlated (r = 0.54). Comparison between distensibility values in the ascending and descending aorta and study of these values with aging indicated a greater coherence with expected physiological behavior of the aorta when using SSFP images.\n\nDiscussion. -

Flow artifacts were more severe in PC images and could explain the better results obtained when using SSFP sequences.\n\nConclusion. – A more accurate local assessment of the aortic stiffness is obtained from SSFP image sequences than from PC image sequences.

“Objective Approximately 10% of young adults report non-medical use of stimulants (cocaine, amphetamine, methylphenidate), which puts them at risk for the development of dependence. This fMRI study investigates whether subjects at early stages of stimulant use show altered decision making processing. Methods 158 occasional stimulants users (OSU) and 50 comparison subjects (CS) performed a “risky gains” decision making task during which they could select safe options (cash in 20 cents) or gamble them for double or nothing in two consecutive gambles (win or lose 40 or 80 cents, “risky decisions”). The primary analysis focused on risky versus safe decisions.
