The scientific and technical concepts related to nuclear medicine
Nuclear medicine is a specialized area in medicine that involves radiology and radioactive materials or radiopharmaceuticals for imaging to diagnose and treat common conditions through the use of radioactive chemical tracers (Wehrl et al., 2015). The radiation is also being used to destroy unhealthy tissues that cannot be treated through the ruse of ordinary medical techniques.
Depending on the type of examination done, radiotracers or radiopharmaceuticals are injected into someone’s bloodstream, inhaled, or swallowed to target specific tumors through staging them. The materials eventually amass in the body under examination through the formation of energy-like forms of gamma rays detected by an imaging device or camera to provide molecular information (Kereiakes and Rosenstein, 2019). The other type of radiation exploit is radioactive iodine medication for hyperthyroidism or treatment of cancer, and radioactive antibodies commonly used to treat lymphomas.
Both the patient and the radiologist determine patients’ preparation for nuclear medicine procedures. How radiologists prepare patients for the nuclear medicine procedure, determine the accuracy of the results. Likewise, how patients prepare for the procedures varies with the patient requirement, current health status, and history since different patients will need different examinations (Van den Wyngaert et al., 2016). Nevertheless, nuclear medicine procedures depend on the type of exam. The patient is given a radioisotope either orally or by a shot to heighten the organ’s imagining or vascular structure being examined. Until then, when a camera is used to scan the region and produces imagery results that the doctor later communicated to the patient.
The advantage of using nuclear energy is that it’s transforming the medical field in giving hope to patients with different illnesses and ailments. Nuclear medicine uses radiopharmaceutical or radioactive tracers to diagnose different organ functions, structure conditions, and ailments in organs, tissues, and body systems (Biassoni and Easty, 2017). For instance, a positron emission tomography (PET) scan is being used to scan tissue and organ functions through tracers and examine chemical activities in the body areas. According to the studies, PET scans are used to trace cancer cells through spotting parts with high metabolic rates to detect, check the spread, if the treatment is working, or find cancer recurrence in the brain or other organs and tissues. Nuclear medicine therapy uses radiopharmaceutical or radionuclides drugs when disorganizing for cancer (Knapp and Dash, 2016). The drugs are administered through mouth or vein. They collect in areas where cancer cells are detected, making it possible for doctors to deliver radiation doses of chemotherapy to the affected area.
Also, tracers are applied to reveal heart disease or part of the body with decreased blood flow, which offers doctors information on whether to perform angioplasty to open clogged arteries or perform coronary artery bypass surgery. The advantage of this application is through PET scans, the patient can get advanced treatments, and the radiologists can detect such heart disorders early and accorded the needed treatment. Similarly, a PET scan is being used to evaluate brain disorders like tumors in the brain, seizures, and other diseases. Signal send by the tracer processes a 3-D image to trace brain injuries and to assess brain tissues and their working (Afshari et al., 2018). However, despite the effectiveness of nuclear medicine, the main disadvantage is that it’s associated with allergic reactions and different health risks when the patient is exposed to the radiation for a prolonged period.
