    <p> <strong>Sonography of Normal and Abnormal Thyroid and Parathyroid Glands<br> Andrioli, M. (Rome); Valcavi, R. (Reggio Emilia)</strong> </p><p><em>Video FHR442273_Video01</em> <br> Ultrasonographic appearance of chronic autoimmune thyroiditis. </p><p><em> Video FHR442273_Video02<br></em> Mixed nodule in the right thyroid lobe. </p><p><em> Video FHR442273_Video03<br></em>Elastosonographic evaluation of a solid nodule in the right thyroid lobe. </p><p><strong>Hybrid Molecular Imaging in Differentiated Thyroid Carcinoma <br> Schmidt, D.; Kuwert, T. (Erlangen)</strong> </p><p><em> Video FHR442276_Video01<br></em>SPECT of the cervical region of a patient with iodine-positive mediastinal lymph node metastases of a papillary thyroid carcinoma (see figure 1d–f). </p><p><em>Video FHR442276_Video02<br></em>FDG-PET visualized by a maximum intensity projection (MIP): a patient with a solitary bone metastasis of a papillary thyroid carcinoma in the iliac crest. </p><p><em> Video FHR442276_Video03<br></em>FDG-PET visualized by a maximum intensity projection (MIP): a patient with several pulmonal metastases and a solitary bone metastasis, as well as solitary cervical lymph node metastasis of a follicular thyroid carcinoma in the iliac crest. </p><p> <strong>Adrenal Imaging: Magnetic Resonance Imaging and Computed Tomography<br> McCarthy, C.J.; McDermott, S.; Blake, M.A. (Boston, Mass.)</strong> </p><p><em> Video FHR442213_Video01</em><br>A series of images obtained during cone-beam CT during the right adrenal vein sampling. </p><p><em>Video FHR442213_Video02</em><br>Left adrenal vein sampling in another patient. </p><p><strong>Intraoperative Magnetic Resonance Imaging for Pituitary Adenomas<br> </strong><strong>Buchfelder, M.; Schlaffer, S.-M. (Erlangen)</strong> </p><p><em> Video FHR442228_Video01</em><br>Workflow for intraoperative MR imaging in the ‘brain suite’: when the surgeon believes that he or she has resected the tumor, the upper portion of the head coil is mounted and the patient’s head is draped and rotated into the center of the magnet for intraoperative imaging. On the basis of the results it is then decided whether the procedure can be finished or one has to proceed with further resection. </p><p><em> Video FHR442228_Video01</em><br>Operative situs during transsphenoidal surgery of the same patient as in figure 6. The segmented contours of the adenoma are superimposed into the microsurgical operative field. The right-sided parasellar lesion (yellow) semi-encases the right carotid artery (blue). During tumor resection, the localization of the carotid artery, as displayed by navigation, is confirmed with the laser Doppler and by intraoperative fluorescence angiography. Thus, the localization of structures which by themselves are not visible by direct light is made available to the surgeon. </p><p> <br></p

    <p>Axial slices of MRI data in upward order with the Broca and Wernicke speech areas (yellow), fMRI activations (white and yellow) and ventral pathways along the inferior fronto-occipital fasciculus (IFOF) reconstructed by global search (GS) (green). Images show patient (female, 36 years old) with language lateralized to the left hemisphere and with a left temporal astrocytoma (WHO grade II, shown in red).</p
