Diagnostic Imaging for Cancer Care
What is the purpose of diagnostic tests?
Cancer patients may undergo many different types of tests in order to accurately diagnose their disease, determine their prognosis and monitor their cancer for progression or recurrence.
Diagnostic imaging involves visualization of abnormal masses using high-tech machines that create images. Examples of diagnostic imaging include x-rays, computed tomography (CT) scans, positron emission tomography (PET) scans, magnetic resonance imaging (MRI), and combined PET/CT scans.
The term "diagnostic test" can be misleading, as these tests are not used only for diagnosing cancer, but also for monitoring cancer progression. There are many reasons for employing diagnostic tests depending on whether the disease is active or progressing, being treated, or in remission.
