Advancements in radiographic imaging techniques for early cancer detection

The present review articles are focused much on the changes which have taken place in the imaging methodologies, especially with regard to computed tomographic (CT) imaging in relation to the early diagnosis of cancer. The background information on modern medical imaging is provided in the article, starting with naked eye inspection and its progressive changes into X rays, fluoroscopy, CT scans and beyond. The article gives the basic working principles and the uses of CT scan in great detail especially in finding and following up different types of cancer. The advanced imaging techniques such as high-resolution computed tomography (HRCT), and micro computed tomography (μCT) have also been covered in the paper where their use in studying bone structures and other preclinical studies that involve high resolution imaging has been highlighted. The role of these techniques in the early diagnosis and management of various conditions including cancer, cardiovascular disease, and disorders of the nervous system has been examined. Nonetheless, the risks of CT scanning are also noted in this review; particularly, the frequency of exposure to the CT scans of patients and the effect that may have after a long period of time.&nbsp
