Review
Nuclear imaging (scintigraphy) is a noninvasive diagnostic procedure that can provide complementary information to that obtained by radiography, CT, MRI, or ultrasonography. Nuclear imaging is based on physiologic distribution of radiopharmaceutical compounds within the body so that it allows assessment of organ functions. When digital image processing is employed, nuclear imaging can allow quantitative assessment of organ function. This article provides an overview of common nuclear imaging procedures used in veterinary medicine.

Review
Nuclear medicine bone scans are a highly effective diagnostic tool, particularly when conducted in conjunction with other radiologic examinations. Typically, bone scans are used to diagnose a variety of skeletal conditions that cover the entire skeleton or occur in a specific location, including metastatic bone cancer, bone infections, or bone injuries. For each procedure, a small amount of a radiopharmaceutical agent is administered to the patient before scanning, and areas of the body that might be damaged or under repair will adsorb the agent. In general, bone scans are noninvasive with little to no adverse effects and are an important step in assessing the health of the skeletal system.

Review
The thyroid gland was one of the first organs imaged in nuclear medicine, beginning in the 1940s. Thyroid scintigraphy is based on a specific phase or prelude to thyroid hormone synthesis, namely trapping of iodide or iodide analogues (ie, Tc99m pertechnetate), and in the case of radioactive iodine, eventual incorporation into thyroid hormone synthesis within the thyroid follicle. Moreover, thyroid scintigraphy is a reflection of the functional state of the gland, as well as the physiological state of any structure (ie, nodule) within the gland. Scintigraphy, therefore, provides information that anatomical imaging (ie, ultrasound, computed tomography [CT], magnetic resonance imaging) lacks. Thyroid scintigraphy plays an essential role in the management of patients with benign or malignant thyroid disease. In the former, the structure or architecture of the gland is best demonstrated by anatomical or cross-sectional imaging, such as ultrasound, CT, or even magnetic resonance imaging. The role of scintigraphy, however, is to display the functional state of the thyroid gland or that of a clinically palpable nodule within the gland. Such information is most useful in (1) patients with thyrotoxicosis, and (2) those patients whose thyroid nodules would not require tissue sampling if their nodules are hyperfunctioning. In neoplastic thyroid disease, thyroid scintigraphy is often standard of care for postthyroidectomy remnant evaluation and in subsequent thyroid cancer surveillance. Planar radioiodine imaging, in the form of the whole-body scan (WBS) and posttherapy scan (PTS), is a fundamental tool in differentiated thyroid cancer management. Continued controversy remains over the utility of WBS in a variety of patient risk groups and clinical scenarios. Proponents on both sides of the arguments compare WBS with PTS, thyroglobulin, and other imaging modalities with differing results. The paucity of large, randomized, prospective studies results in dependence on consensus expert opinion and retrospective analysis with inherent bias. With a growing trend not to ablate low-risk patients, so that a PTS cannot be performed, some thyroid carcinoma patients may never have radioiodine imaging. In routine clinical practice, however, imaging plays a critical role in patient management both before and after treatment. Moreover, as evidenced by the robust flow of publications concerning WBS and PTS, planar imaging of thyroid carcinoma remains a topic of great interest in this modern age of rapidly advancing cross sectional and hybrid imaging with single-photon emission computed tomography, single-photon emission computed tomography/CT, and positron emission tomography/CT.

Review
Dual-modality imaging is a technique in which computed tomography (CT) or magnetic resonance imaging is combined with positron emission tomography or single-photon emission CT to acquire structural and functional images with an integated system. The data are acquired in a single procedure; the patient remains on the scanner table while undergoing both x-ray and radionuclide studies to facilitate correlation between the structural and functional images. The resulting data can aid in localization, enabling more specific diagnosis than can be obtained with a conventional imaging study. In addition, the anatomic information can be used to compensate the correlated radionuclide data for physical perturbations such as photon attenuation, scatter radiation, and partial volume errors. Thus, dual-modality imaging provides a priori information that can improve both the visual quality and the quantitative accuracy of the radionuclide images. Dual-modality imaging systems are also being developed for biologic research involving small animals. Small-animal dual-modality systems offer advantages for measurements that currently are performed invasively with autoradiography and tissue sampling. By acquiring data noninvasively, dual-modality imaging permits serial studies in a single animal, enables measurements to be performed with fewer animals, and improves the statistical quality of the data.
