“…Normally, there is high tracer uptake in the skull base, orbits, nasal region, temporomandibular joints, and cranial sutures, whereas absence of uptake may be seen in the region of the anterior fontanelle. As growth centers close, the biodistribution of 99m Tc-MDP gradually reaches the adult pattern (76)(77)(78)(79)(80)(81)(82)(83)(84). One special indication in this age group is evaluation for skeletal injury in suspected cases of child abuse (85).…”

“…Furthermore, trauma from suspected nonaccidental injury often results in multiple skeletal fractures at different stages of healing. Skeletal scintigraphy offers a highly sensitive imaging tool for evaluation of the entire skeleton (84). Osseous stress or fracture may be identified on skeletal scintigraphy by increased radiotracer uptake within a few hours of symptom onset and before radiographic changes appear (80,81).…”

Learning Objectives: On successful completion of this activity, participants should be able to describe, for children less than 1 y old, (1) the wide variety of nuclear medicine indications; (2) the nuclear medicine studies, relative to other imaging methods, that can provide the highest diagnostic yield; (3) how to obtain high-quality nuclear medicine examinations at the lowest radiation exposures; (4) how growth and development affect the appearance, and therefore the interpretation, of nuclear medicine images; and (5) special care needed, such as patient preparation, immobilization, distraction techniques, environment, sedation or general anesthesia, imaging techniques, image processing, and presentation of results.Financial Disclosure: The authors of this article have indicated no relevant relationships that could be perceived as a real or apparent conflict of interest.

Patients in this age group present with a spectrum of diseases different from those of older children or adults. These patients can benefit from the full range of nuclear medicine studies. In these young children, nuclear medicine studies are more likely to be used to evaluate a wide range of congenital conditions but also can be helpful for evaluating acquired conditions such as infection, cancer, and trauma. This review first will cover the general aspects of nuclear medicine practice with these patients, including the special considerations that can help achieve successful diagnostic imaging. These topics will include clinical indications, imaging technology, instrumentation, software, positioning and immobilization, sedation, local and general anesthesia, radiopharmaceutical doses, radiation risk, and dose reduction. The review then will discuss the specific nuclear medicine studies that typically are obtained in patients in this age group. With extra care and attention to the special needs of this population, nuclear medicine departments can successfully study patients less than 1 y old.

“…Absence of involvement of adjacent discs helps differentiate spinal LCH from osteomyelitis or discitis [ 52 ]. On bone scan, lesions may show increased, decreased, or normal activity [ 7 ]. Bone scans and radiographic skeletal surveys are complementary, as some lesions are evident on only one of these imaging techniques [ 21 ].…”

This chapter fi rst discusses general principles of tumor imaging, including both characteristics of benign and malignant tumors and utility of different imaging modalities. It then enters an in-depth discussion of benign tumors and tumor-like lesions, addressing cystic, cartilaginous, osseous, fi bro-osseous, and vascular lesions, along with Langerhans cell histiocytosis. It concludes with a review of osteosarcoma and Ewing sarcoma, the more common malignant tumors, as well as chondrosarcoma, lymphoma, malignant fi brous histiocytoma, and metastatic disease.

“…67 False-negative findings in suspected osteomyelitis can be owing to the bone scan being performed within 24 hours of occurrence of symptoms. 68 In some patients with osteomyelitis, especially in children, increased marrow space pressure or thrombosis of blood vessels results in paradoxically decreased tracer uptake and a cold or photopenic lesion. 1 False-negative scintigraphic studies are unusual but have been reported, more commonly in neonates.…”
