CT evaluation

What are CT evaluations?

CT evaluations, or computed tomography evaluations, are diagnostic procedures that utilise specialised X-ray equipment to obtain detailed images of the inside of the body. These images, often referred to as CT scans or CAT scans, provide valuable information about the structures and tissues within the body, particularly the lungs and respiratory system, in the context of pulmonary health.

When are CT evaluations recommended?

CT evaluations are recommended in various clinical scenarios, particularly in the field of pulmonology. Some common reasons for recommending CT evaluations include:

• Diagnosis and monitoring of lung conditions CT scans are invaluable tools for diagnosing and evaluating a diverse range of lung conditions, such as pneumonia, bronchitis, pulmonary fibrosis, chronic obstructive pulmonary disease (COPD), lung cancer, and pulmonary embolism.
• Assessment of respiratory symptoms: When patients present with symptoms such as a long-term cough, shortness of breath, chest pain, or abnormal chest X-ray findings, CT evaluations may be recommended to further investigate the underlying cause.
• Pre-operative evaluation: Prior to certain lung surgeries or interventions, CT evaluations may be performed to assess the anatomy of the lungs and surrounding structures, aiding in surgical planning and minimising risks.
• Follow-up after treatment: CT scans may be used to evaluate the effectiveness of treatment interventions, such as chemotherapy, radiation therapy, or surgical resection, in managing lung diseases or tumours.
• Screening for lung cancer: In individuals at increased risk for lung cancer, such as heavy smokers or those with a history of lung cancer, CT screenings may be recommended for early detection and intervention.

What do CT evaluations involve?

CT evaluations involve the use of specialised X-ray equipment to acquire multiple cross-sectional images of the chest or other targeted areas of the body. The procedure typically lasts a few minutes and is painless. Patients may be required to hold their breath briefly during the scan to minimise motion artefacts and ensure clear images.

During a CT scan, computers and x-ray machines are used to produce detailed images of the body. During the scan, you will be asked to lie inside a specially designed-machine while X-rays are taken from various angles. In some cases, a contrast dye is administered so that your internal structures can be more clearly seen.

A CT evaluation may be recommended in cases where it is necessary to perform a diagnosis. Because the X-ray images are so detailed, it is possible to view the blood vessels and other internal structures, identify the location of tumours, and diagnose infections and disorders.
