Oncologic imaging: interactions of nuclear medicine with CT and MRI using the bone scan as a model.

摘要: There are many radionuclides currently used in oncologic imaging including technetium 99m diphosphonates, gallium 67, thallium 201, sestamibi, and others. The specific interactions of each these agents with computed tomography (CT) magnetic resonance (MRI) extensive. radionuclide bone scan using Tc diphosphonate is the most frequently performed nuclear medicine examination imaging. can be as a model to generalize CT MRI. applications for other procedures include evaluating metastases, assessing response therapy, guiding radiation therapy planning. Bone findings that equivolcal metastases evaluated modalities. Areas abnormal uptake axial skeleton or MRI, whereas those appendicular plain radiographs, followed by MRI if necessary. valuable because its high sensitivity lesion detection, ease whole body imaging, low cost. major disadvantage it lacks fine anatomic detail, which particular importance cancer patient local back pain, radiculopathy, myelopathy. Because pain without radiculopathy earliest symptom spinal cord compression 90% patients, an study choice exquisite depiction anatomy. A myelogram postmyelogram there contraindications basic principle detection provided detail applied also use
