I consider the Medical Imaging Specialisation 2 Unit to be useful for upgrading my skills and knowledge which will have a positive impact on my future career.
I have chosen to work on the evidence related to the diagnostic modality of computed tomography (CT) with contrast agent that enhances the resolution because it is an effective method with outstanding diagnostic accuracy even though it also has some drawbacks.
This unit had four unit learning outcomes (ULOs). The first ULO is to analyse the role of the field or specialisation modality that I have chosen which is CT scanning as a diagnostic process. The second ULO is to study how the principles of the chosen field CT can be applied to facilitate effective participation at work as a part of a radiology department team. The third ULO is to describe the major aspects of the chosen modality and present a range of daily ordinary examinations and operations within the subject matter. The fourth ULO is to analyse the current research in the field of CT scan application and to study how it can be applied in the future in the framework of the health care context.
1.0 Case Study
The first part of the assignment involves the case study evidence. I have chosen the case of pulmonary embolism (PE) that affects young patients as it is a life-threatening condition that is challenging to diagnose because the symptoms are frequently minor or vague. I am interested in this subject matter because it is important to have extensive knowledge about one of the major challenges in cardiovascular emergency and a condition that has a high fatality rate if it is diagnosed late or improperly. I have learnt that the medical field considers immediate diagnosis and treatment of pulmonary embolism to be a crucial priority task. My case study focused on the case of a 21-year-old female athlete with extensive pulmonary embolism which was revealed with a CT angiogram. She did not have any typical risk factors for pulmonary embolism (post-operative states elderly age inherited factors unhealthy way of life immobility etc.); rather her embolism was the result of trauma to her veins after she underwent extrinsic compression during her athletic training as well as repetitive arm movements and the ingestion of oral contraceptives which appear to be risk factors for a young athlete.
While conducting the PE investigation the sub-modality of my interest was CT angiography (CTA). I learnt that resolution improvements in the efficient high-quality newly enhanced systems and multi-sided CT scanners ensure that small blood clots which used to be unnoticeable can be detected. I learnt that CTA is the most efficient method for detection of PE if its probability rate is high. Without a doubt CTA is non-invasive; however its effectiveness depends on the optimal contrast protocols the appropriate volume of the contrast agent the contrast injection flow rate cardiovascular circulation and anatomical coverage.
As PE is typically diagnosed via a combination of methods (chest X-ray electrocardiogram blood tests checking the patients medical history etc.) I learnt how crucial it is to participate in this procedure as part of a team. This lesson will be valuable for me in the future. Furthermore the case study enabled me to revise the basics of examination procedures related to CTA so I will be able to ensure that the proper anatomical areas are imaged. Moreover I learnt a lot about the procedures of artefact detection related to CTA and I realized how important the contrast agents in CTA are improve the diagnostic value.
