Review of Magnetic Resonance System and Positron Emission Tomography Machines


In this contemporary world, technology continues to prove decisive in the medical sector. The pharmaceutical industry has witnessed innovations that work to fight cancer, high blood pressure and many other ailments. For instance, recently, a company manufacturing medical equipment came up with the Magnetic Resonance System and the PET scanner. The machine plays a fundamental role towards fighting cancer. It works to detect cancer at the early state, therefore, provide a likelihood for treating and controlling cancer. Rationally, cancer is treatable but at a first stage.

At the same time, it is a hazardous disease when not handled in real time. Therefore, I strongly recommend that the major stakeholders in the health sector should come on board and champion for the appreciation and accommodation of the Magnetic Resonance System and the PET system as they play a fundamental role in the detection and prevention of Cancer and other lifestyle diseases. Attributable to the above elucidations, this paper in writing seeks to discuss the advantages that emanate as a result of using the Magnetic Resonance System the PET scanner and provide a recommendation.


Magnetic Resonance SystemThe Magnetic Resonance System commonly denoted by the acronym (MRI) is a must buy machine to nearly the entire medical industry (Stoller, 2015). The MR is an innovative device that captures the images of the body from various facets and epitomizes an excellent supplement to the diagnostic armamentarium. The pictures or the images captured vary in accordance with the examined tissues and depict the chemical and physical components. According to WEBB (2016) the MR system is a non-invasive and appears to be moderately harmless and safe as regards its application in the medical sector.

The device as well works in a manner that it cuts and reduces exposure towards the ionizing radiations. The innovation and technology that has been tested in the device prove to be helpful and useful towards the medical sector that strives to combat cancer. The MR provides unusual rewarding in the detection, assessment, as well as, localization of the prevalence, characters, and character of diseases present in the musculoskeletal, central nervous system and the cardiovascular systems. In the scanning of the brain, for instance, the devices prove its capability to define some anomalies in the form of plaques of multiple sclerosis as captured using other scanning devices and tumors.

Furthermore, the MR system can capture and provide information concerning the circulation of blood throughout the body system and the blood vessels. The report works to enhance the capability of clinicians to detect any malpractices and problems in the blood system hence provide corrective measures (Levitt, 2013).

Reasonably, research shows that the MR is entirely safe for use. In that, the risks are fundamentally linked to the oscillating as well as the static magnetic fields that are employed in the MR system. The tracks are in a position of creating biological effects at a satisfactorily high exposure. However, the effects have not been witnessed at that levels presently used in the medical and clinical practice. On the contrary, the MR system has some disadvantages. Its best-identified risk is the projectile risk. The risk entails the powerful attraction of ferromagnetic objects towards the magnets used. However, one must exercise caution when the objects of ferromagnets entrench in the patient, as, for instance, implants or shrapnel. Besides, the MR system should not be used by the patients who suffer from cardiac arrests or aneurysm clips (Jolesz, 2014).

Positron Emission Tomography (PET)The Positron Emission Tomography commonly denoted by the acronym PET is a noninvasive device that is employed to undertake imaging that works to detect the gamma rays from positron-emitting isotopes. In fact, it is a nuclear medicine imaging machine (DAS, 2015). It is a big machine that is round, and doughnut-like shaped hole in the centre. The tool contains several detector rings that capture and record energy emission from the radiotracer of a body (Santiago, 2015). The device undertakes a critical role as regards diagnosis and treatment of various diseases. PET enhances the capability of the clinicians to view, scrutinize an assess the body of a human being from both the biochemical and functional perspective. The PET device assesses the blood circulation, use of oxygen in the body, sugar metabolism among others. Reasonably, as an innovatively accurate and sensitive imaging technology that bases on molecular biology, the PET device shows an exception capability to assess the functioning and analyze the biochemical processes that the body tissues show as altered in the primary phases of nearly all diseases.

In fact, the PET device works to establish the following variations, which are often prior anatomical, as well as the structural changes. The PET device is beneficial to the medical sector in some ways. Given that, the method works to provide information that it gains from accessing the numerous processes that the body engages. For instance, the analysis of the blood circulation, sugar metabolism and use of oxygen in the body (Wall, 2017). Besides, most of the information captured and provided during the scan is unattainable when using other procedures of imaging. The device is accurate and useful hence saving the costs of undertaking several tests to determine the cause of an inefficiency in the body as it provides the information using nuclear scans as compared to exploratory tests and surgery (Hess & H??ilund-Carlsen, 2014). In fact, research shows that nuclear medicine researchers offer the most accurate findings in the field of medicine.

The device is real time as it works to detect the early start of a disease prior to the condition being evident in other devices that offer the imaging tests. The aspect of timeliness and early detection of diseases reduces the treatment cost and hence opportunities to fight deadly diseases, as, for example, cancer. The device also reduces radiation to the patients as it uses minute doses of the radiotracer, hence resulting in comparatively low exposure to radiation. Besides, the test on the device shows no adverse effects towards the patient as a result of low-dose use (Rosette, 2009).

The PET device also exercises caution and therefore safe for use. It works to enlighten the patient of the eminent risks before the treatment, hence, give the patient the opportunity to ask questions and determine the risks by weighing the risks and the benefits that emanate as a result of using the PET device. However, the device may at times lead to an allergic reaction as a result of using radiopharmaceuticals products. But, then again, the chances are rare and minimal as the radiopharmaceutical products are of quality and standard. Nevertheless, it is required that the patient should notify the personnel in charge of nuclear medicine of any allergies (Wall, Blanksma, Niemeyer, & Paans, 2013).

Responses and Conclusion

The MR system and the PET device are a must acquire by the medical fields and stakeholders. The review shows that the machines are outstanding, efficient and effective towards the scrutiny of diseases. For instance, in the case of cancer, it can detect the anomalies early enough to enhance its treatment. The tools work to diagnose primary tumor, restaging, metastasis, restaging and most importantly they provide monitoring benefits in nearly all tumors and diseases. Similarly, the tools have the capacity to analyze the head, esophagus, neck, breast, thyroid, and melanoma of any abnormalities that may cause cancer or other diseases (Peller, Subramaniam & Guermazi, 2012).

Both the MR and PET machines provide critical and functional information of both the biological and functional body processes. The mentioned-above capabilities of the MR and the PET machines are identified by not only the clinicians and the research scientists, but as well by the CMS body that has assessed the machines capacity and approved the production and coverage of the MR and the Pet. Owing to the sheer nature of the discussion regarding the MR and PET machines, I recommend that the healthcare sector should consider employing the Magnetic Resonance System and the Positron Emission Tomography machines. The machines play a pivotal role in detecting cancer at early stage, as well as, other diseases.
