Diagnostic and therapeutic radiography are the two prominent types of radiography. Both these types deal with extensive technology developed for investigation of physiology, pathology and anatomy of the human body. In diagnostic radiography, high quality imaging of body is done which will interpret diagnosis regarding injuries and disease. While, in therapeutic radiography planning and delivery of required treatments using x-ray and other radioactive sources are provided.

Diagnostic radiography is one of the important types of radiography. It involves the applications of science and technology to patients. X-ray, Fluoroscopy, Computer Tomography (CT), Magnetic Resonance Imaging (MRI), Angiography and Ultrasound are some of the imaging technologies, which use diagnostic radiography. With the help of x-ray, we can examine bones, cavities and foreign objects in the body while, fluoroscopy gives the images of digestive system of the body. CT scan gives cross sectional view of the body. A 2-D and 3-D map of various types of tissue within the body can be obtained using diagnostic radiography. Blockage in the blood vessels can be investigated in angiography utilizing diagnostic radiography.

There are number of interrelated elements used in diagnostic radiography to maintain high quality of images. A small error can affect the quality and required medical information can not be transferred. In such cases, patient has to re-expose to generate images with adequate information. But, such re-exposure may dangerous. In case of pregnant women fetal absorbed dose of diagnostic radiation and time of exposure plays the vital role generate risks.

Therapeutic radiography is also known as radiotherapy. This includes delivering doses of x-rays and other ionizing radiations to patients. Most of these patients are suffering from cancers. An accurate dose of radiation must be applied only on the affected area of the body, preventing surrounded unaffected tissues. Hence, a skilled person is required to handle instruments used in therapeutic radiography. The planning of the process is vital part of these types of radiography. Localization is the first stage of therapeutic radiography. Usually, in this stage the exact location of tumor and its size are identified. MRI or CT scans are performed if necessary. Dosimetry planning is the second stage. In this the planning of treatment, exact parameters required for the treatments and measurements of radiations are analyzed. Before actual treatment begins, all the side effects of the radiotherapy are to be interpreted to patient.
