  • There have been several significant advances innuclearmedicine since the publication of the second edition of Practical NuclearMedicine. The last seven years have seen great strides in instrumentation, including new coincidence detectors, the development of a wider variety of crystals, and the advent of combined anatomical/functional imaging devices, including PET/CT and SPECT/CT. PET imaging with 18F-FDG has become a mainstay of many clinical settings, and other radiotracers are finding theirway into the rapidly expanding field of oncologic PET.

  • Although a general understanding persists that the human brain functions similarly in women and in men, an increasing body of knowledge indicates that neuronal connectivity, recruitment, and disease patterns exhibit gender differences. Imaging techniques such as positron emission computerized tomography (PET) and single photon emission computerized tomography (SPECT) have highlighted some gender-based differences in human brain function.

  • Congenital Anomalies of the Lumbar Spine Spondylolysis is a bony defect in the pars interarticularis (a segment near the junction of the pedicle with the lamina) of the vertebra; the etiology may be a stress fracture in a congenitally abnormal segment. The defect (usually bilateral) is best visualized on oblique projections in plain x-rays, CT scan, or single photon emission CT (SPECT) bone scan and occurs in the setting of a single injury, repeated minor injuries, or growth.

  • Although dyspnea is a common symptom, there has been only limited investigation of its prognostic significance among patients referred for cardiac evaluation. methods We studied 17,991 patients undergoing myocardial-perfusion single-photon-emission computed tomography during stress and at rest. Patients were divided into five categories on the basis of symptoms at presentation (none, nonanginal chest pain, atypical angina, typical angina, and dyspnea).

  • Photovoltaics have started replacing fossil fuels as major energy generation roadmaps, targeting higher efficiencies and/or lower costs are aggressively pursued to bring PV to cost parity with grid electricity. Third generation PV technologies may overcome the fundamental limitations of photon to electron conversion in single-junction devices and, thus, improve both their efficiency and cost. This book presents notable advances in these technologies, namely organic cells and nanostructures, dye-sensitized cells and multijunction III/V cells. ...

  • QDs play an important role mainly in the imaging and as highly fluorescent probes for biological sensing that have better sensitivity, longer stability, good biocompatibility, and minimum invasiveness. The fluorescent properties of QDs arise from the fact, that their excitation states/band gaps are spatially confined, which results in physical and optical properties intermediate between compounds and single molecules. Depending on chemical composition and the size of the core which determines the quantum confinement, the emission peak can vary from UV to NIR wavelengths (400–1350 nm).
