Final answer:
Diagnostic procedures that produce images of body structures include X-ray and MRI. X-rays are used for viewing bones, while MRIs provide detailed images of organs and tissues. Other imaging techniques such as CT scans and ultrasound also offer valuable insights into the body's internal structures.
Step-by-step explanation:
A medical assistant should identify 1) X-ray and 2) MRI as diagnostic procedures that produce images of body structures. These are part of a group of medical imaging technologies used extensively in medicine. An X-ray can depict a two-dimensional image of a body region, typically used for viewing bones or dense structures. In contrast, an MRI, or Magnetic Resonance Imaging, utilizes a magnetic field and radio waves to generate detailed images of the organs and tissues in the body. These technologies provide vital data for disease diagnoses and are invaluable tools in modern medicine.
Other imaging techniques mentioned, such as CT scans and ultrasound, similarly provide different but valuable views into the body's interior. CT scans use computer processing of X-ray measurements to produce cross-sectional views of the body, while ultrasound uses sound waves to produce images, which is highly favorable for monitoring pregnancies due to the lack of ionizing radiation.
Blood tests and physical examinations are also critical diagnostic tools but do not produce images of body structures, and therefore are not considered imaging techniques.
