Review article: effect of nuclear medicine on paediatric imaging.

Detailed understanding of anatomy and pathology is central to radiology. If functional imaging can be incorporated into the overall picture of the patient then the “radiologist” stands in a unique position to assist the clinician, not only with establishing the diagnosis but also with assessing the effectiveness of therapy. The role of nuclear medicine varies with different organ systems; almost every nuclear medicine examination must be based on a firm anatomical foundation and therefore radiology (including ultrasound, CT and MRI) must be available close to the time of the nuclear medicine study. There are certain nuclear medicine examinations which are truly complementary to well-established anatomical studies, e.g. ventilation/perfusion (V/Q) lung scans with the chest radiograph or 99Tcm HMPAO brain scans with CT or MRI. Other nuclear medicine examinations have however replaced radiological investigations, e.g. 99Tcm DMSA for the IVU in renal scarring, or the bone scan for the skeletal survey when sta...
