Final answer:
The term referring to minimally invasive diagnostic and treatment procedures is interventional radiology, which includes techniques like radioembolization and the use of an endoscope for surgeries and biopsies.
Step-by-step explanation:
The term that refers to the use of a minimally invasive procedure for both diagnostic purposes and for treatment is interventional radiology. This field is associated with minimally invasive techniques that offer alternatives to traditional surgical procedures, often using radioactive materials and radiation. For instance, interventional radiologists may perform radioembolization to treat liver tumors by implanting radioactive seeds that obliterate the tumor's blood supply, avoiding the need for major surgery or chemotherapy.
Another common minimally invasive procedure is the use of an endoscope, which allows doctors to look inside the body and perform surgery or take biopsy samples with minimal incisions. Conditions such as endometriosis can be treated laparoscopically, and even some bariatric surgeries for weight loss are conducted by making small incisions to limit food intake and nutrient absorption, reflecting the wide range of applications for minimally invasive techniques in medical treatment and diagnosis.
