RESUMO
The field of nuclear cardiology has grown significantly over the past decade. This is a reflection of the value seen by providers in these safe and effective procedures. Nuclear scan studies are noninvasive and versatile in their usefulness. These studies assist in determining the likelihood of future cardiac events, guide approaches to revascularization, and assist in evaluation of the adequacy of revascularization procedures. Critical thinking and decision-making abilities are two key requirements for nurses in the critical care environment. Knowledge and understanding of the nuclear scan studies indicated for patients help nurses advocate for those in their care.

The four basic techniques of medical imaging are X-ray, ultrasound, magnetic resonance and radionuclide. This article describes imaging techniques that display anatomical structure and those that are better at showing the physiological function of organs and tissues. Safety and preparation relating to nursing practice are discussed. Understanding the purpose and limitations of the different imaging techniques is important for providing best patient care.

Cancer surgery has existed as an elective treatment modality for more than 150 years, yet it is relatively unsophisticated in light of the advances seen in other medical disciplines. Using the nuclear medicine technique of lymphoscintigraphy (i.e., mapping lymph nodes using a radioactive isotope), the surgeon can perform a sentinel lymph node biopsy that targets only the lymph nodes that first drain a primary tumor site. This procedure can provide accurate staging information without risking the potential morbidity associated with lymph node dissection. This type of precise biopsy is made possible by using a gamma-detecting instrument coupled with an ultrasensitive probe designed for intraoperative use.
