CZT MPI SPECT and LV function: Cochet and colleagues evaluate myocardial perfusion imaging using cadmium-zinc-telluride SPECT cameras to measure left ventricular global and regional function and also assess absolute wall motion and thickness measurements with cardiac MR as a reference.
Sex differences in extraaortic 18F-FDG: Kaneko and colleagues describe differences in extraaortic arterial 18F-FDG accumulation in asymptomatic men and women to clarify the association between such accumulation and both cardiovascular risk factors and coronary artery stenosis.

99mTc(CO)3(NTA) and 131I-OIH: Taylor and colleagues compare the pharmacokinetics of these tracers in imaging patients with stage 3–4 renal failure and describe the potential of the new 99mTc agent for routine clinical measurement of effective renal plasma flow.
PET/CT lymphoscintigraphy in oral cancer: Heuveling and colleagues investigate the clinical feasibility of PET/CT lymphoscintigraphy using 89Zr-nanocolloidal albumin in patients with early-stage oral cancer.
Dynamic bone imaging: Wong and Piert offer an educational overview of the mechanisms of uptake of 99mTc-labeled diphosphonates and 18F-sodium fluoride and discuss and compare the performance of these bone-seeking radiotracers in clinical and research applications.
In vivo Bmax and Kd of 11C-GR103545: Tomasi and colleagues describe the development of this selective κ-opioid receptor PET tracer and the results of a study in rhesus monkeys to estimate in vivo receptor concentration and dissociation equilibrium constant.
PET and cardiac hypertrophy: Zhong and colleagues use a mouse model of transverse aortic constriction to explore the hypothesis that metabolic remodeling with increased 18F-FDG uptake precedes and triggers severe contractile dysfunction in pressure-overload left ventricular hypertrophy.
Imaging V/Q in a model of COPD: Jobse and colleagues assess ventilation/perfusion SPECT imaging in mouse studies to determine the ways in which chronic exposure to cigarette smoke affects the lungs, with special reference to early functional changes.

ON THE COVER

As can be seen in this patient, SPECT/CT clarifies the anatomic location of the SLNs located outside the extended pelvic lymphadenectomy field (white and pink arrows). See page 493.
